Changes

Version 1.5.2

2024-11-03

  • Partially revert #393 to fix progress reporting outside of Emacs.
  • Do not depend on unbounded-delays on ppc64, s390x and riscv64 (#371, #422, #423).

Version 1.5.1

2024-06-22

  • Performance improvements (#389, #390).
  • Progress reporting in Emacs: use \r instead of ANSI escape sequences (#393).
  • Console reporter: fix unintended change to foldHeading (#396).
  • Prune empty test subtrees from TestTree (#403).
  • Add instance Eq Timeout and instance Ord Timeout (#415).
  • Add ability to supply options for launchers and reporters at the top-level of test tree (#417).

Version 1.5

2023-09-10

  • Progress reporting is no longer ignored. PrintTest constructor of TestOutput now has an extra field used to report progress. Supply const (pure ()) as this extra field value if you want to skip progress reporting (#311).
  • foldGroup now takes [b] instead of b as its last argument to allow for custom fold strategies. This is a backwards incompatible change, but you can get the old behavior by applying mconcat (#364).
  • Dependency loop error now lists all test cases that formed a cycle (#340).
  • Dependencies can now be defined pattern-free with sequentialTestGroup (#343).
  • Added --min-duration-to-report flag that specifies the time a test must take before tasty outputs timing information (#341).
  • When a test failed with an exception, print it using displayException instead of show (#330).
  • The -p / --pattern option can be specified multiple times; only tests that match all patterns are run (#380).
  • Fix color scheme to make info messages visible in terminals with white background (#369).
  • When parsing of a command-line option failed, report received option (#368).
  • Support WASM (#365).
  • Tested with GHC 8.0 - 9.8.

Version 1.4.3

2022-12-18

  • Drop unbounded-delays dependency on 64-bit machines (#344).
  • Drop clock dependency, decomission clock flag (#345).
  • Drop wcwidth dependency (#346)
  • Tested with GHC 8.0 - 9.4.

Version 1.4.2.3

2022-05-10

  • Drop mtl dependency
  • Warning-free under GHC 8.0 - 9.2

Version 1.4.2.2

2022-05-10

  • Fix compilation with mtl-2.3
  • Tested with GHC 8.0 - 9.2; dropped support for GHC 7.x

Version 1.4.2.1

Fix warnings under GHC 9.2

Version 1.4.2

  • Add consoleTestReporterWithHook
  • Suggest pattern to rerun an individual failing test
  • Add Test.Tasty.Patterns.Printer

Version 1.4.1

Deduplicate command line options when there is more than one TestReporter. Expose the function that does that, uniqueOptionDescriptions.

Version 1.4.0.3

Fix CPP warning/error macro expansion producing 'defined' has undefined behavior

Version 1.4.0.2

Automatically disable the dependency on the clock package when compiled by ghcjs.

Version 1.4.0.1

The only point of this release is to introduce compatibility with GHCs back to 7.0 (see #287).

Note, however, that these changes are not merged to the master branch, and the future releases will only support the GHC/base versions from the last 5 years, as per our usual policy. To test with even older GHCs, you'll have to use this particular version of tasty (or have the constraint solver pick it for you when testing with older GHCs).

The source of this release is in the support-old-ghcs branch of the tasty repository.

Version 1.4

  • Change the TreeFold data type to give all functions access to OptionSet
  • Fix a bug where a looping failure message escaped the time out set for the test
  • Fix a bug where pattern changes inside the TestTree weren't respected

Version 1.3.1

  • Add an ability for a test provider to print colorful/formatted output

Version 1.3

  • IsOption has a new method showDefaultValue for customizing how defaultValues are rendered in the --help output.
  • Drop support for GHCs older than 5 years
  • Do not install handlers for the signals that dump core
  • Export the AnsiTricks type/option
  • In addition to a Parser, optionParser and suiteOptionParser now return a [String] representing warning messages:
    • A warning is emitted if an IsOption instance defines multiple options in the implementation of optionCLParser.
    • An warning is emitted if an IsOption instance's optionCLParser implementation assigns a default value (e.g., with Options.Applicative.value), as this interferes with tasty's ability to read environment variable arguments.

Version 1.2.3

  • Expose computeStatistics from Test.Tasty.Ingredients.ConsoleReporter.
  • Ensure that finally and bracket work as expected inside tests when the test suite is interrupted by Ctrl-C.

Version 1.2.2

  • Expose timed and getTime
  • Add parseOptions
  • Allow to disable ANSI tricks with --ansi-tricks=false

Version 1.2.1

  • Document and expose installSignalHandlers
  • Enable colors in Emacs and other almost-ANSI-capable terminals

Version 1.2

Make it possible to declare dependencies between tests (see the README for details)

Version 1.1.0.4

Make tasty work with GHCJS

Version 1.1.0.3

Fix compatibility with GHC 8.6

Version 1.1.0.2

Fix a bug where some (mostly Asian) characters would break alignment in the terminal output

Version 1.1.0.1

Fix a bug where -l was still using / instead of . as a field separator

Version 1.1

NOTE: This major release contains some breaking changes to the semantics of patterns. In the original pattern design I didn't notice the conflict between using / as a field separator and as the AWK syntax for pattern matching /.../.

The new patterns have been around for a relatively short time (5 months), so hopefully the breakage won't be too big. I'm sorry about any problems caused by the change.

See #220 for the discussion.

  • The field separator in patterns is changed from slash (/) to period (.), and . is now allowed in raw patterns.

    The field separator is used to join the group names and the test name when comparing to a pattern such as -p foo or -p /foo/.

    If you used

    -p 'foo/bar'

    or

    -p '/foo\/bar/'

    before, now you should use

    -p 'foo.bar'

    or

    -p '/foo.bar/'

    if you meant "test/group bar inside group foo, or

    -p '/foo\/bar/'

    if you meant "test/group containing foo/bar in the name".

    The need for escaping the slash inside the /.../ pattern was precisely the motivation for this change.

  • Raw patterns (ones that are not AWK expressions) may no longer contain slashes (/).

    So

    -p 'foo/bar'

    is no longer allowed, and

    -p '/foo/'

    is now parsed as an AWK expression /foo/, whereas before it was treated as a raw pattern and converted to /\/foo\//.

    The reason for this change is that /foo/ is a valid AWK expression and should be parsed as such.

  • Raw patterns may now contain hyphens, so e.g. -p type-checking now works.

    In theory this makes some valid AWK expressions (such as NF-2) not to be parsed as such, but they are either unlikely to be useful or could also be expressed in other ways (NF!=2).

  • Several new exports, mostly for testing/debugging patterns:

    • TestPattern now has a Show instance; TestPattern and Expr now have Eq instances.
    • The constructors of TestPattern are now exported.
    • parseAwkExpr is introduced and can be used in ghci to see how an AWK expression is parsed. (For parsing test patterns, which include raw patterns in addition to AWK expression, use parseTestPattern.)

Version 0.8.0.2

Make ansi-terminal an unconditional dependency

Version 0.8

  • Test.Tasty.Ingredients is now exposed
  • Test.Tasty.Ingredients.Basic is added, which exports the ingredients defined in the tasty package. These exports should now be used instead of ones exported from Test.Tasty.Runners
  • The Result type is now structured a bit differently. Providers now should use testPassed and testFailed functions instead of constructing Results directly.
  • Add «quiet mode» (see README)
  • Add «hide successes» mode (see README)
  • Add short command-line options: -j for --num-threads, -p for --pattern
  • Add timeout support
  • AppMonoid is renamed to Traversal for consistency with the 'reducers' package. Another similar wrapper, Ap, is introduced.
  • Fix a resources bug (resources were not released if the test suite was interrupted)
  • The type of launchTestTree is changed. It now takes a continuation as an argument. This is necessary to fix the bug mentioned above.
  • Add flagCLParser to be used as the optionCLParser implementation for boolean options.
  • Add the ability to pass options via environment

Version 0.7

  • Use regex-tdfa instead of regex-posix (which is a native implementation, and as such is more portable)
  • foldTestTree now takes the algebra in the form of a record rather than multiple arguments, to minimize breakage when new nodes are added or existing ones change
  • withResource now passes the IO action to get the resource to the inner test tree

Version 0.6

  • Better handling of exceptions that arise during resource creation or disposal
  • Expose the AppMonoid wrapper
  • Add askOption and inludingOptions

Version 0.5.2.1

Depend on ansi-terminal >= 0.6.1. This fixes some issues with colors on Windows.

Version 0.5.2

  • Export Result and Progress from Test.Tasty.Runners
  • Make it clear that only GHC 7.4+ is supported

Version 0.5.1

Export ResourceSpec from Test.Tasty.Runners

Version 0.5

Add a capability to acquire and release resources. See the «Resources» section in the Test.Tasty docs.

For the end users, the API is backwards-compatible.

Test runners may have to be adjusted — there is a new constructor of TestTree and a new argument of foldTestTree.

Version 0.4.2

Add defaultIngredients

Version 0.4.1.1

Print the failure description in red

Version 0.4.0.1

Fix a bug (#25)

Version 0.4

The big change in this release is introduction of ingredients, which is a replacement for runners. But unless you have a custom runner, this is unlikely to affect you much.

The Ingredient data type has replaced the Runner type.

The following functions have been renamed and possibly changed their types:

  • defaultMainWithRunner → defaultMainWithIngredients
  • treeOptionParser → suiteOptionParser
  • getTreeOptions → treeOptions
  • runUI → consoleTestReporter

Added in this release:

  • suiteOptions
  • optionParser
  • functions operating on ingredients
  • testsNames
  • the listingTests ingredient and its option, ListTests

NumThreads is no longer a core option, but is automatically included in the test reporting ingredients (see its haddock).

Version 0.3.1

  • Proper reporting of (some) non-terminating tests (#15)
  • Upgrade to optparse-applicative 0.6

Version 0.3

  • Restrict dependency versions
  • Fix a bug where non-terminating test would lead to a deadlock (#15)

Version 0.2

  • Add an execRunner function
  • Make Runner return IO Bool

Version 0.1.1

Set lower bound on optparse-applicative dependency version
