refactor: Migrate list commands to flag handler pattern #1788
Conversation
…Parser - Reorganize all list commands into cmd/list/ directory following command registry pattern - Replace legacy flag handling with StandardParser and Options structs for all 10 list subcommands - Add comprehensive environment variable support (ATMOS_* prefix) for all flags - Create shared newCommonListParser() factory for DRY flag management across commands - Eliminate deep exits - checkAtmosConfig now returns errors for better testability - All existing tests pass with new implementation Commands migrated: - list stacks, components, themes (simple flags) - list workflows, vendor (medium complexity) - list instances, metadata, settings (common flags + processing flags) - list values, vars (most complex with abstract, vars, query support) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

🧹 Nitpick comments (14)
cmd/list/instances.go (1)
13-24: InstancesOptions + parser wiring look solid, options are ready for future useThe StandardParser + newCommonListParser setup cleanly registers common list flags plus
--upload(withATMOS_LIST_UPLOAD) and buildsInstancesOptionsembeddingglobal.Flags. Even thoughInstancesOptionsisn’t consumed yet inexecuteListInstancesCmd, it gives you a stable place to hang future behavior or tests without affecting current semantics. I’d leave it as‑is unless you’re certain you won’t need options here, in which case you could trim the struct and constructor for now.Also applies to: 59-73
cmd/list/stacks.go (1)
21-27: Stacks command wiring is consistent; minor error-wrapping tweak is optional
StacksOptions+stacksParsercorrectly wire the--componentflag (andATMOS_COMPONENT) through StandardParser into options, andlistStacksWithOptionscleanly goes throughInitCliConfig→ExecuteDescribeStacks→FilterAndListStacks, with a nice “No stacks found” UX. If you ever want richer introspection on errors here, you could switch thefmt.Errorf("error ...: %v", err)calls to use%wand sentinel errors (similar to the values file) so callers canerrors.Ison them, but that’s strictly a nicety, not a blocker.Also applies to: 29-65, 67-97
cmd/list/values.go (3)
39-42: Values + vars commands align with the StandardParser pattern and env supportThe move to
ValuesOptionswith embeddedglobal.Flagsand the twin parsers (valuesParser/varsParser) looks clean—flags are centrally registered vianewCommonListParser, environment overrides (ATMOS_LIST_ABSTRACT,ATMOS_LIST_VARS,ATMOS_PROCESS_TEMPLATES,ATMOS_PROCESS_FUNCTIONS) are wired throughWithEnvVars, and RunE consistently doescheckAtmosConfig(),BindFlagsToViper, andflags.ParseGlobalFlags. Thevarsalias forcingQuery: ".vars"while dropping theVarsflag keeps the semantics straightforward. The extralen(args)check on top ofcobra.ExactArgs(1)is a bit redundant; if you want to trim noise you could rely on Cobra’s arg validation and drop the manual guard, but that’s optional.Based on learnings.
Also applies to: 44-108, 110-167, 169-223
243-265: Filter option helpers correctly model--vars, query, and CSV/TSV delimiter behavior
getFilterOptionsFromValuesandprepareListValuesOptionsdo a nice job of centralizing how CLI options translate intol.FilterOptions:Varsforcing the query to.vars,Stackmapping toStackPattern, and the special handling of.varsviaComponentFiltervsComponentmatches the needs of the extractor. The small CSV tweak—switching the delimiter fromDefaultTSVDelimitertoDefaultCSVDelimiteronly whenformat == csvand the user hasn’t explicitly overridden the delimiter—nicely avoids surprising tab‑delimited “CSV” output while preserving explicit overrides. If you find yourself needing the same CSV/TSV default behavior in other list commands, it might be worth pulling this into a shared helper, but it’s fine to keep scoped here for now.Also applies to: 275-302
24-37: listValuesWithOptions error handling is solid; consider whether process- flags should affect existence checks*
listValuesWithOptionshas well-structured error handling: it uses explicit sentinels (ErrComponentNameRequired,ErrInitializingCLIConfig,ErrDescribingStacks), wraps underlying errors viafmt.Errorf(ErrFmtWrapErr, ...)forerrors.Iscompatibility, distinguishesComponentDefinitionNotFoundErrorfromNoValuesFoundError, and logs a friendly “no values/vars” message before returning nil for the latter. One subtle point:listutils.CheckComponentExistscurrently callsExecuteDescribeStackswith its own hard-coded flags, while the main values flow callsExecuteDescribeStackswithopts.ProcessTemplates/opts.ProcessFunctions. If your intention is that--process-templates/--process-functionsfully define the view of the world (including whether a component “exists”), you may eventually want to thread these options through to the existence check as well to avoid potential mismatches in edge cases where templates/functions introduce components. Not urgent, but worth keeping in mind.Based on learnings.
Also applies to: 303-355
cmd/list/themes.go (1)
20-27: Themes command cleanly adopts Options + StandardParser while remaining tolerant of missing config
ThemesOptionsplusthemesParserfollow the same StandardParser pattern as the other list commands, and wiring--allthroughATMOS_LIST_ALL_THEMESkeeps env behavior consistent. InexecuteListThemesWithOptions, treatingInitCliConfigfailures as “no active theme” rather than hard errors meansatmos list themesstill works even if the user’s config is absent or broken, which feels like the right trade‑off for a purely informational command. If you ever want better diagnosability, you could log the init error at a debug level when it occurs, but functionality-wise this looks good.Also applies to: 28-37, 45-59, 61-98
cmd/list/workflows.go (1)
79-87: listWorkflowsWithOptions composes config + list config cleanly; CSV delimiter behavior is a future polish
listWorkflowsWithOptionsusesInitCliConfig(configAndStacksInfo{}, false)purely to obtainatmosConfig.Workflows.List, then delegates toFilterAndListWorkflows, which matches the signature shown in the list package. That layering keeps config resolution in one place. There is some inevitable duplication becauseFilterAndListWorkflowswill also init config whenfileFlag == "", but the overhead is minor for this command. If you want parity with the values command, you could later introduce the same “auto-switch toDefaultCSVDelimiterwhenformat == csvand delimiter is still at the TSV default” behavior here so that--format csvwithout an explicit--delimiteryields comma-separated output, but that’s a refinement, not a bug.cmd/list/metadata.go (2)
36-47: Add explicit Args validation for the optional component argument
metadataCmd’sUsestring advertises an optional[component], butArgsis not set, so Cobra will accept and silently ignore any extra positional args beyond the first. For consistency withsettingsCmdand clearer UX, consider enforcing a single optional argument.You could tighten this up like:
var metadataCmd = &cobra.Command{ - Use: "metadata [component]", - Short: "List metadata across stacks", - Long: "List metadata information across all stacks or for a specific component", + Use: "metadata [component]", + Short: "List metadata across stacks", + Long: "List metadata information across all stacks or for a specific component", Example: "atmos list metadata\n" + "atmos list metadata c1\n" + "atmos list metadata --query .component\n" + "atmos list metadata --format json\n" + "atmos list metadata --stack '*-{dev,staging}-*'\n" + "atmos list metadata --stack 'prod-*'", + Args: cobra.MaximumNArgs(1), RunE: func(cmd *cobra.Command, args []string) error {
146-157: Avoid calling ExecuteDescribeStacks twice when a component filter is providedWhen
componentFilteris non-empty,listMetadataWithOptionsfirst callslistutils.CheckComponentExists, which internally runsExecuteDescribeStacks, and then callsExecuteDescribeStacksagain to obtainstacksMap. On large stacks this can be noticeably expensive.If feasible, consider one of these approaches:
- Drop the explicit
CheckComponentExistsand rely on the downstream listing logic to surface aComponentDefinitionNotFoundError/NoValuesFoundError, or- Reuse the first
stacksMapfromCheckComponentExistsinstead of recomputing it.This would keep behavior the same while avoiding duplicate stack traversal.
cmd/list/components.go (3)
29-35: Double-check that forbidding positional args doesn’t break existing usage
componentsCmdis declared withArgs: cobra.NoArgs, which meansatmos list components <stack>will now be rejected and users must use--stackinstead.If prior versions accepted an optional stack positional argument, this is a breaking change. If you want to preserve that convenience while still preferring the flag, you could allow at most one arg and map it into the stack option:
var componentsCmd = &cobra.Command{ - Use: "components", - Short: "List all Atmos components or filter by stack", - Long: "List Atmos components, with options to filter results by specific stacks.", - Args: cobra.NoArgs, + Use: "components", + Short: "List all Atmos components or filter by stack", + Long: "List Atmos components, with options to filter results by specific stacks.", + Args: cobra.MaximumNArgs(1), RunE: func(cmd *cobra.Command, args []string) error { @@ - opts := &ComponentsOptions{ - Flags: flags.ParseGlobalFlags(cmd, v), - Stack: v.GetString("stack"), - } + stack := v.GetString("stack") + if len(args) == 1 && stack == "" { + stack = args[0] + } + + opts := &ComponentsOptions{ + Flags: flags.ParseGlobalFlags(cmd, v), + Stack: stack, + }If the old command never supported positional stacks, then the current
NoArgsbehavior is fine.
67-81: Consider enabling stack completion for --stack as in other list subcommandsThe
componentscommand defines a--stackflag but doesn’t hook intoaddStackCompletion, unlikemetadataCmdandsettingsCmd. Adding completion here would make the UX consistent across list commands.For example:
func init() { // Create parser with components-specific flags using functional options componentsParser = flags.NewStandardParser( flags.WithStringFlag("stack", "s", "", "Filter by stack name or pattern"), flags.WithEnvVars("stack", "ATMOS_STACK"), ) // Register flags componentsParser.RegisterFlags(componentsCmd) + + // Add stack completion + addStackCompletion(componentsCmd) // Bind flags to Viper for environment variable support if err := componentsParser.BindToViper(viper.GetViper()); err != nil { panic(err) } }
83-96: Align error wrapping with list error types for consistency
listComponentsWithOptionswraps failures fromInitCliConfigandExecuteDescribeStackswithfmt.Errorf(...)strings, whilemetadata/settingsuse the typed errors inpkg/list/errors. Using the same typed errors here would make behavior more uniform and easier to test.Something along these lines:
-import ( - "fmt" - "strings" +import ( + "fmt" + "strings" @@ - l "github.com/cloudposse/atmos/pkg/list" + l "github.com/cloudposse/atmos/pkg/list" + listerrors "github.com/cloudposse/atmos/pkg/list/errors" @@ func listComponentsWithOptions(opts *ComponentsOptions) ([]string, error) { configAndStacksInfo := schema.ConfigAndStacksInfo{} atmosConfig, err := config.InitCliConfig(configAndStacksInfo, true) if err != nil { - return nil, fmt.Errorf("error initializing CLI config: %v", err) + return nil, &listerrors.InitConfigError{Cause: err} } stacksMap, err := e.ExecuteDescribeStacks(&atmosConfig, "", nil, nil, nil, false, false, false, false, nil, nil) if err != nil { - return nil, fmt.Errorf("error describing stacks: %v", err) + return nil, &listerrors.DescribeStacksError{Cause: err} }That would keep the user-visible messages essentially the same while aligning with the rest of the list commands.
cmd/list/settings.go (2)
101-112: Optional: use a shared constant for the “settings” component key (if available)
setupSettingsOptionshard-codes"settings"as the component key. Ifpkg/listdefines aKeySettings(similar toKeyMetadata), using that would avoid duplicating the string literal and keep things aligned with the metadata command.If such a constant exists, the change would be:
func setupSettingsOptions(opts *SettingsOptions, componentFilter string) *l.FilterOptions { return &l.FilterOptions{ - Component: "settings", + Component: l.KeySettings,If there’s no existing constant, the current code is fine.
124-154: Same double ExecuteDescribeStacks pattern as metadata when componentFilter is setAs with
listMetadataWithOptions, the settings path will:
- Call
listutils.CheckComponentExists, which internally executesExecuteDescribeStacks, and then- Call
ExecuteDescribeStacksagain to obtainstacksMap.On large configs this can be more work than necessary.
If you later decide to optimize, the same options apply here as for metadata:
- Drop the explicit existence check and let the listing logic surface a not-found error, or
- Reuse the first
stacksMapfor both existence checking and filtering.This doesn’t block the PR, but it’s a good candidate for a small follow-up improvement.

Timestamp: 2025-10-07T00:25:16.333Z
Learning: In Atmos CLI, subcommands inherit flags from their parent commands via Cobra's command inheritance. For example, `atmos terraform metadata --help` shows `--affected` and related flags inherited from the parent `terraform` command (defined in cmd/terraform.go), even though the metadata subcommand doesn't explicitly define these flags. This is expected Cobra behavior and auto-generated help screengrabs accurately reflect this inheritance.

Learning: In the Atmos codebase, commands using the `StandardParser` flag pattern (from pkg/flags) do NOT need explicit `viper.BindPFlag()` calls in their code. The StandardParser encapsulates flag binding internally: flags are registered via `parser.RegisterFlags(cmd)` in init(), and bound via `parser.BindFlagsToViper(cmd, v)` in RunE, which internally calls viper.BindPFlag for each flag. This pattern is used throughout Atmos (e.g., cmd/toolchain/get.go, cmd/toolchain/info.go, cmd/toolchain/install.go, cmd/toolchain/path.go). Do not flag missing viper.BindPFlag calls when StandardParser is used.

Learning: The Atmos codebase uses a consistent pattern for commands that delegate to external tools: `PersistentFlags().Bool("", false, doubleDashHint)` where doubleDashHint provides help text about using double dashes to separate Atmos options from native command arguments. This pattern is used across terraform, packer, helmfile, atlantis, aws, and ansible commands.

Learning: In the cloudposse/atmos repository, command merging prioritizes precedence over display ordering. Help commands are displayed lexicographically regardless of internal array order, so the mergeCommandArrays function focuses on ensuring the correct precedence chain (top-level file wins) rather than maintaining specific display order.

Learning: In Atmos CLI, subcommands inherit flags from their parent commands via Cobra's command inheritance. For example, `atmos terraform metadata --help` shows `--affected` and related flags inherited from the parent `terraform` command (defined in cmd/terraform.go), even though the metadata subcommand doesn't explicitly define these flags. This is expected Cobra behavior and auto-generated help screengrabs accurately reflect this inheritance.

Instead, document the OpenTofu requirement in code comments and documentation, trusting users who enable the feature (e.g., `PassVars`) to ensure their terraform command points to an OpenTofu binary.

Learning: In the Atmos codebase, commands using the `StandardParser` flag pattern (from pkg/flags) do NOT need explicit `viper.BindPFlag()` calls in their code. The StandardParser encapsulates flag binding internally: flags are registered via `parser.RegisterFlags(cmd)` in init(), and bound via `parser.BindFlagsToViper(cmd, v)` in RunE, which internally calls viper.BindPFlag for each flag. This pattern is used throughout Atmos (e.g., cmd/toolchain/get.go, cmd/toolchain/info.go, cmd/toolchain/install.go, cmd/toolchain/path.go). Do not flag missing viper.BindPFlag calls when StandardParser is used.

Learning: In the Atmos codebase, when a function receives an `*schema.AtmosConfiguration` parameter, it should read configuration values from `atmosConfig.Settings` fields rather than using direct `os.Getenv()` or `viper.GetString()` calls. The Atmos pattern is: viper.BindEnv in cmd/root.go binds environment variables → Viper unmarshals into atmosConfig.Settings via mapstructure → business logic reads from the Settings struct. This provides centralized config management, respects precedence, and enables testability. Example: `atmosConfig.Settings.AtmosGithubToken` instead of `os.Getenv("ATMOS_GITHUB_TOKEN")` in functions like `getGHCRAuth` in internal/exec/oci_utils.go.

cmd/docs_generate.go (1)
20-21: Nice simplification.Removing the explicit argument check is the right move since
cobra.ExactArgs(1)on line 17 handles validation, andExecuteDocsGenerateCmdalso validates args. Cleaner flow.cmd/cmd_utils.go (2)
817-832: Clean wrapper implementation.The function properly initializes config, describes stacks, and filters results. Error propagation is good.
834-856: Wrapper looks good.The silent error handling on line 839 (defaulting
stackFlagto""when flag read fails) is reasonable for completion contexts where the flag may not be set.cmd/list/utils.go (4)
19-36: Good refactor for testability.Returning errors instead of calling
Exitis a key improvement per the PR objectives. The optionalskipStackCheckparameter adds flexibility for commands that don't require stack validation.
38-44: Stack completion setup looks good.Properly checks for existing flag before adding and registers completion.
46-97: Completion and listing functions are well-structured.The functions properly separate concerns and handle errors appropriately for completion contexts.
99-119: Nice factory pattern.Centralizing common list flags and env var bindings in one place reduces duplication. The extensibility via
additionalOptionsis a good touch.cmd/list/vendor_test.go (1)
1-15: LGTM!Package rename aligns with the refactor. The test documents that the vendor command doesn't require stack processing, which is a useful design constraint to capture.
cmd/root.go (1)
48-48: LGTM!Side-effect import follows the established pattern for command registration. The list package's init() function will automatically register all list subcommands.
cmd/list/workflows_test.go (1)
1-15: LGTM!Package rename is correct. Test consistently documents that the workflows command doesn't require stack processing.
cmd/list/instances_test.go (1)
1-105: LGTM!Comprehensive test coverage for the instances command. Tests verify flags, argument validation, command structure, and options handling. Well-structured and thorough.
cmd/list/list_test.go (2)
1-1: LGTM!Package rename aligns with the refactor.
188-204: LGTM!Command variable references updated to match the new modular structure (removing the "list" prefix). The tests maintain their coverage while working with the new command names.
cmd/list/settings_test.go (1)
1-186: LGTM!Comprehensive test coverage for the settings command. Tests verify flags, argument validation, command structure, and options handling. Table-driven tests for setupSettingsOptions provide good scenario coverage.
cmd/list/vendor.go (2)
60-81: LGTM!Parser initialization follows the StandardParser pattern correctly. Environment variable bindings are appropriate, and the panic on bind error is acceptable in init() to prevent silent configuration failures.
83-97: LGTM!The helper function correctly calls InitCliConfig with
processStacks=falseand maps options appropriately. This aligns with the test expectations in vendor_test.go.cmd/list/list.go (1)
1-48: LGTM!Clean implementation of the list command module. The ListCommandProvider pattern is correctly implemented, and all 10 subcommands are properly registered. The command structure follows the established conventions.
cmd/list/instances.go (1)
26-56: Execution path forlist instancescorrectly reuses common CLI plumbingThe RunE flow—
checkAtmosConfig(),instancesParser.BindFlagsToViper, thenProcessCommandLineArgs("list", cmd, args, nil)andlist.ExecuteListInstancesCmd—matches the established pattern for commands that need full config/stack context. Explicitly settingCommand = "list"andSubCommand = "instances"onconfigAndStacksInfokeeps downstream logic unambiguous. No issues here from a wiring or correctness standpoint.Also applies to: 75-85
cmd/list/themes.go (1)
142-216: TTY-aware theming and recommended indicators behave consistently with the--allflag
displayThemes,formatThemesTable, andformatSimpleOutputnicely separate concerns: TTY detection viaterm.IsTTYSupportForStdout()decides between the styled table and plain text, and both paths useopts.Alland theshowingRecommendedOnlyflag so the star indicator and footer message only appear in “show everything” mode. Including the active theme marker (>) regardless of mode is a good touch. The rendering logic is straightforward and doesn’t surface any edge-case issues.Also applies to: 218-261
cmd/list/workflows.go (1)
16-25: Workflows command is wired correctly into list.FilterAndListWorkflows with env-backed flags
WorkflowsOptionsandworkflowsParsercorrectly surface--file,--format, and--delimiter(withATMOS_WORKFLOW_FILE,ATMOS_LIST_FORMAT,ATMOS_LIST_DELIMITERenv overrides) through StandardParser andflags.ParseGlobalFlags. The RunE flow—checkAtmosConfig(true),BindFlagsToViper, build options,listWorkflowsWithOptions, thenPrintMessageInColor—is consistent with the rest of the list commands and keeps the output nicely themed. Nothing blocking here.Also applies to: 26-57, 59-77
cmd/list/metadata.go (2)
79-98: StandardParser wiring and env var support look aligned with the shared patternUsing
newCommonListParserwithRegisterFlags(metadataCmd)ininit()andBindFlagsToViperinRunE, plusBindToViper(viper.GetViper())for env var support, matches the StandardParser pattern used elsewhere and should preserve the expected flag/env precedence.Based on learnings
167-175: Graceful handling of NoValuesFoundErrorMapping
NoValuesFoundErrorto a specific “No metadata found” log message and returning("", nil)keeps the CLI exit status clean while still signaling the condition to users, and lets other errors propagate unchanged.cmd/list/settings.go (1)
156-173: Consistent, user-friendly handling of empty settings outputLogging “Filtering settings …” at debug level, then translating
NoValuesFoundErrorinto a “No settings found” info log and a("", nil)result mirrors the metadata behavior and keeps non-empty error cases distinct from the “nothing to show” case.

File: website/src/components/Screengrabs/atmos-terraform-metadata--help.html:25-55
Timestamp: 2025-10-07T00:25:16.333Z
Learning: In Atmos CLI, subcommands inherit flags from their parent commands via Cobra's command inheritance. For example, `atmos terraform metadata --help` shows `--affected` and related flags inherited from the parent `terraform` command (defined in cmd/terraform.go), even though the metadata subcommand doesn't explicitly define these flags. This is expected Cobra behavior and auto-generated help screengrabs accurately reflect this inheritance.

Learning: In the cloudposse/atmos repository, CLI documentation files in cmd/markdown/ follow a specific format that uses " $ atmos command" (with leading space and dollar sign prompt) in code blocks. This is the established project convention and should not be changed to comply with standard markdownlint rules MD040 and MD014.

Learning: In the Atmos codebase, commands using the `StandardParser` flag pattern (from pkg/flags) do NOT need explicit `viper.BindPFlag()` calls in their code. The StandardParser encapsulates flag binding internally: flags are registered via `parser.RegisterFlags(cmd)` in init(), and bound via `parser.BindFlagsToViper(cmd, v)` in RunE, which internally calls viper.BindPFlag for each flag. This pattern is used throughout Atmos (e.g., cmd/toolchain/get.go, cmd/toolchain/info.go, cmd/toolchain/install.go, cmd/toolchain/path.go). Do not flag missing viper.BindPFlag calls when StandardParser is used.

Learning: The Atmos codebase uses a consistent pattern for commands that delegate to external tools: `PersistentFlags().Bool("", false, doubleDashHint)` where doubleDashHint provides help text about using double dashes to separate Atmos options from native command arguments. This pattern is used across terraform, packer, helmfile, atlantis, aws, and ansible commands.

84-86: Consider graceful error handling instead of panic.The
panic(err)in the init function will crash the application at startup ifBindToViperfails. While this might be acceptable for catching programming errors during development, consider logging a fatal error or returning the error through a lazy initialization pattern for more graceful handling and testability.

Learning: In Atmos (internal/exec/terraform.go), when adding OpenTofu-specific flags like `--var-file` for `init`, do not gate them based on command name (e.g., checking if `info.Command == "tofu"` or `info.Command == "opentofu"`) because command names don't reliably indicate the actual binary being executed (symlinks, aliases). Instead, document the OpenTofu requirement in code comments and documentation, trusting users who enable the feature (e.g., `PassVars`) to ensure their terraform command points to an OpenTofu binary.

Learning: The "ExecuteAtmosValidateSchemaCmd" function in internal/exec/validate_schema.go has been reviewed and confirmed to have acceptable cognitive complexity despite static analysis warnings. The function uses a clean structure with only three if statements for error handling and delegates complex operations to helper methods.

Timestamp: 2025-11-08T19:56:18.660Z
Learning: In the Atmos codebase, when a function receives an `*schema.AtmosConfiguration` parameter, it should read configuration values from `atmosConfig.Settings` fields rather than using direct `os.Getenv()` or `viper.GetString()` calls. The Atmos pattern is: viper.BindEnv in cmd/root.go binds environment variables → Viper unmarshals into atmosConfig.Settings via mapstructure → business logic reads from the Settings struct. This provides centralized config management, respects precedence, and enables testability. Example: `atmosConfig.Settings.AtmosGithubToken` instead of `os.Getenv("ATMOS_GITHUB_TOKEN")` in functions like `getGHCRAuth` in internal/exec/oci_utils.go.

cmd/list/instances_test.go (4)
11-49: Consider testing the actual command instead of a mock.This test creates a fresh
cobra.Commandand manually adds flags, then verifies they exist. It's testing Cobra's flag mechanism rather than the actualinstancesCmd. Consider either:
- Testing
instancesCmddirectly (likeTestListInstancesCommanddoes on line 67)- Removing this test if flag registration is already verified elsewhere
Example refactor to test the real command:
-func TestListInstancesFlags(t *testing.T) { - cmd := &cobra.Command{ - Use: "instances", - Short: "List all Atmos instances", - Long: "This command lists all Atmos instances or is used to upload instances to the pro API.", - Args: cobra.NoArgs, - } - - cmd.PersistentFlags().String("format", "", "Output format") - cmd.PersistentFlags().String("delimiter", "", "Delimiter for CSV/TSV output") - cmd.PersistentFlags().String("stack", "", "Stack pattern") - cmd.PersistentFlags().String("query", "", "JQ query") - cmd.PersistentFlags().Int("max-columns", 0, "Maximum columns") - cmd.PersistentFlags().Bool("upload", false, "Upload instances to pro API") - - formatFlag := cmd.PersistentFlags().Lookup("format") +func TestListInstancesFlags(t *testing.T) { + // Test actual command from package + formatFlag := instancesCmd.PersistentFlags().Lookup("format") assert.NotNil(t, formatFlag, "Expected format flag to exist") assert.Equal(t, "", formatFlag.DefValue) - delimiterFlag := cmd.PersistentFlags().Lookup("delimiter") + delimiterFlag := instancesCmd.PersistentFlags().Lookup("delimiter") assert.NotNil(t, delimiterFlag, "Expected delimiter flag to exist") assert.Equal(t, "", delimiterFlag.DefValue) + // ... continue for other flags
52-63: Consider removing framework behavior test.This test verifies Cobra's built-in
NoArgsvalidator works correctly. Since it doesn't test Atmos-specific logic, it could be removed or consolidated withTestListInstancesCommandwhich already verifies the Args validator on line 72-76.
80-105: Remove tautological struct tests.These tests assign values to struct fields and verify they were assigned correctly. This tests Go's language behavior rather than Atmos logic. Per the project's CLAUDE.md guidelines, tautological tests should be removed.
If you want to test
InstancesOptions, test actual behavior like:
- How options affect command execution
- Validation logic on options
- Transformation of options into other types
108-170: Convert to behavioral tests or remove.While table-driven tests are good practice, this test is tautological - it assigns struct fields and verifies the assignments succeeded. Consider testing actual behavior instead:
- How do these option combinations affect
listInstancesWithOptions?- Are there validation rules that reject certain combinations?
- Do options transform input/output in expected ways?
If there's no behavior to test yet (integration tests deferred), consider removing this until the behavior is implemented.
docs/prd/test-coverage-implementation-summary.md (1)
81-96: Consider acknowledging test quality variability.The summary states "All tests follow CLAUDE.md guidelines" and "No stub/tautological tests," but the actual test files include several tautological struct validation tests (e.g.,
TestListInstancesOptions,TestMetadataOptions_AllFields). Consider updating this section to acknowledge:
- Option structure tests are baseline validation
- Primary value comes from helper function tests
- Some tests will be replaced with integration tests in Phase 4
This provides a more accurate representation of the current test quality.
cmd/list/utils_test.go (1)
54-63: Remove duplicate test.
TestNewCommonListParser_CreatesValidParserduplicates the "parser with no additional options" case fromTestNewCommonListParser(lines 18-21). The table-driven test already covers this scenario.Apply this diff:
-// TestNewCommonListParser_CreatesValidParser tests that the parser is usable. -func TestNewCommonListParser_CreatesValidParser(t *testing.T) { - parser := newCommonListParser() - assert.NotNil(t, parser, "Parser should not be nil") - - cmd := &cobra.Command{Use: "test"} - assert.NotPanics(t, func() { - parser.RegisterFlags(cmd) - }, "RegisterFlags should work on a fresh command") -}

Learning: In Atmos CLI, subcommands inherit flags from their parent commands via Cobra's command inheritance. For example, `atmos terraform metadata --help` shows `--affected` and related flags inherited from the parent `terraform` command (defined in cmd/terraform.go), even though the metadata subcommand doesn't explicitly define these flags. This is expected Cobra behavior and auto-generated help screengrabs accurately reflect this inheritance.

Learning: In the Atmos codebase, commands using the `StandardParser` flag pattern (from pkg/flags) do NOT need explicit `viper.BindPFlag()` calls in their code. The StandardParser encapsulates flag binding internally: flags are registered via `parser.RegisterFlags(cmd)` in init(), and bound via `parser.BindFlagsToViper(cmd, v)` in RunE, which internally calls viper.BindPFlag for each flag. This pattern is used throughout Atmos (e.g., cmd/toolchain/get.go, cmd/toolchain/info.go, cmd/toolchain/install.go, cmd/toolchain/path.go). Do not flag missing viper.BindPFlag calls when StandardParser is used.

Learning: The Atmos codebase uses a consistent pattern for commands that delegate to external tools: `PersistentFlags().Bool("", false, doubleDashHint)` where doubleDashHint provides help text about using double dashes to separate Atmos options from native command arguments. This pattern is used across terraform, packer, helmfile, atlantis, aws, and ansible commands.

139-197: Solid behavioral test.Good work on this test! It validates actual helper function behavior with meaningful edge cases (flag exists, doesn't exist, different defaults). This follows the CLAUDE.md guidelines for testing behavior rather than implementation.
200-387: Excellent behavioral test coverage.These tests validate real helper function behavior with meaningful scenarios:
getFilterOptionsFromValuestests delimiter transformations, vars flag behavior, and query handlingprepareListValuesOptionstests the distinction between vars and non-vars queries- Table-driven approach with clear expectations
Well done following CLAUDE.md guidelines.
cmd/list/utils_test.go (1)
66-96: Good utility function tests.These tests verify actual behavior of
addStackCompletion:
- Adds flag when missing
- Doesn't panic when flag exists
- Verifies flag properties (shorthand, default)
Good edge case coverage for a utility function.
docs/prd/test-coverage-improvement-plan.md (1)
1-596: Well-structured coverage improvement plan.This plan demonstrates solid understanding of testing best practices:
- Phased approach with clear targets
- Acknowledgment of CLAUDE.md guidelines (lines 428-435)
- Example tests show behavioral testing (lines 519-591)
- Realistic about challenges and dependencies
The plan provides good direction for improving test quality beyond just coverage numbers.

66-170: Strong behavioral test coverage.These tests validate actual transformation logic in
setupMetadataOptions:
- Default query application when empty (lines 153-160)
- Custom query preservation (lines 163-170)
- Complete field mapping from options to filter options (lines 66-129)
Well-structured tests that verify real behavior rather than implementation details.
199-276: Comprehensive option mapping tests.Excellent table-driven test that verifies how different
MetadataOptionscombinations map to filter options. Tests meaningful scenarios:
- All options populated with custom query
- Empty options defaulting to
.metadata- Component filtering behavior
This provides good coverage of the transformation logic.
Remove ineffective TestListVendorCmd_WithoutStacks which only logged a message without any assertions. Replace with TestVendorOptions that actually verifies the VendorOptions structure behavior with various combinations of format, stack, and delimiter values. The removed test claimed to verify that InitCliConfig was called with processStacks=false, but provided no actual verification - it would never fail even if the code changed. The new test validates actual option structure behavior and will fail if the structure changes. Changes: - Remove: TestListVendorCmd_WithoutStacks (t.Log-only test) - Add: TestVendorOptions with 3 test cases (all options, empty, partial) - Add assertions that fail when behavior changes 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
- Add unit test covering the case where homeDir is a prefix of another directory name - Fix obfuscateHomeDirInOutput to only replace homeDir at path boundaries - Refactor into smaller helper functions to reduce cyclomatic complexity - Example: homeDir='/home/user' no longer incorrectly replaces '/home/username' The fix implements boundary-aware string scanning using strings.Builder to scan through the string and only replace homeDir when it's followed by: - End of string - Path separator (already handled by first ReplaceAll) - Non-path characters (space, newline, etc.) This prevents replacing homeDir when it's followed by alphanumeric characters, dashes, or underscores (indicating it's a prefix of another directory name). Helper functions added: - shouldReplaceHomeDir: Checks if homeDir should be replaced at current position - isPathChar: Determines if a character is part of a path component name Test case added: 'homeDir as prefix of another path should not be replaced' All existing tests continue to pass.
- Remove redundant inline comments from obfuscateHomeDirInOutput - Simplify control flow for better readability - No functional changes, only formatting cleanup
