Walkthrough

This pull request updates the pull request template to require that feature branches be in sync with the "main" branch instead of "develop." Additionally, two new GitHub Actions workflows have been added: one to automate build checks (build.yml) and another to run unit tests (test.yml). Both workflows trigger on pushes and pull requests to the "main" branch and follow a series of steps to check out code, set up Java, assign permissions, and execute Gradle commands.

33-59: Android Tests Job Configuration is Comprehensive

The "android_tests" job on macOS is set up properly:

  • It checks out the repository and sets up JDK 21 similarly to the unit tests job.
  • It grants execute permission to the Gradle wrapper.
  • It starts an Android Virtual Device (AVD) using reactivecircus/android-emulator-runner@v2 with clear parameters for API level, emulator architecture, AVD name, and options.

A couple of minor suggestions:

  • Verify Emulator Architecture: Ensure that arch: arm64-v8a is appropriate for your CI environment. If your runner does not support ARM-based emulation, you might need to adjust this parameter.
  • Confirm Target Parameter: The value target: default should be verified against the emulator runner documentation to ensure it behaves as expected.

Otherwise, the configuration effectively supports running connected Android tests.

1-8: Workflow Trigger Configuration Looks Solid

The trigger configuration correctly listens to both push and pull request events on the "main" branch. This ensures that tests are only run for relevant changes.


9-12: Concurrency Settings Are Well Configured

The concurrency block uses a descriptive group identifier ensuring that only the latest run for a pull request or branch is executed. This helps prevent unnecessary CI runs.


13-32: Unit Tests Job is Appropriately Set Up

The job "unit_tests" on Ubuntu is configured correctly:

  • It checks out the repository code using actions/checkout@v4.
  • It sets up JDK 21 with the Temurin distribution while caching Gradle dependencies.
  • It grants execute permission for the Gradle wrapper and runs the unit tests using ./gradlew testDebugUnitTest.

Overall, this job is concise and correctly implemented.

1-2: Workflow Name is Descriptive.
The name "Run Tests" clearly reflects the purpose of the workflow.


3-8: Trigger Configuration is Correct.
The workflow correctly triggers on both pushes and pull requests to the "main" branch, which aligns with project conventions.


9-12: Concurrency Configuration is Well Defined.
The concurrency group using ${{ github.workflow }}-${{ github.event.pull_request.number || github.ref }} ensures that only the most recent run for a given branch or pull request is active, thereby reducing redundant workflow runs.


13-32: Unit Tests Job Setup is Solid.

  • The usage of ubuntu-latest as the runner is appropriate.
  • The checkout step via actions/checkout@v4 and setting up JDK 21 with actions/setup-java@v4 (lines 20-26) is correctly configured with caching enabled for Gradle.
  • Granting execute permissions to gradlew (lines 27-28) and running tests using ./gradlew testDebugUnitTest (lines 30-31) are implemented correctly.

36-37: Repository Checkout in Test Job is Standard.
The checkout step using actions/checkout@v4 in the test job is necessary and follows best practices.


39-44: KVM Enabling Step is Appropriately Implemented.
The multi-line command correctly sets up the udev rules and refreshes the KVM configuration, which is essential for running Android emulators on Ubuntu.

1-2: Workflow Naming is Clear
The workflow name "Run Tests" is concise and descriptive of its purpose.


3-7: Trigger Definitions are Correct
The workflow is set to trigger on both push and pull_request events targeting the "main" branch, which aligns with the repository’s standard branching strategy.


9-11: Effective Concurrency Configuration
The concurrency block, using the expression ${{ github.workflow }}-${{ github.event.pull_request.number || github.ref }}, ensures that only the latest run for a branch or pull request is executed. This helps prevent redundant builds. Consider validating that this expression behaves as expected in all scenarios.


13-32: Unit Tests Job Setup is Solid
The unit_tests job is well configured:

  • It runs on ubuntu-latest.
  • It checks out the repository and sets up JDK 21 using actions/setup-java@v4 with appropriate parameters such as java-version and caching for Gradle.
  • It also ensures that the gradlew script has execute permissions before running ./gradlew testDebugUnitTest.
    This is a good, straightforward setup for running unit tests.

14-32: Unit Tests Job is Well-Structured
The unit_tests job checks out the code, sets up JDK 21 with caching for Gradle, ensures the gradlew script is executable, and runs the Gradle unit tests.

Optional Improvement: Consider adding caching mechanisms for dependencies in the unit_tests job (similarly to the instrumented_tests job) to speed up subsequent runs.


62-71: AVD Snapshot Creation Step is Correct
The conditional creation of an AVD when a cache miss is detected and the subsequent generation of a snapshot is implemented correctly.

Optional Suggestion: Review the emulator options to ensure they fully meet your testing requirements and performance targets.

1-2: Workflow Name is Clear and Descriptive
The name "Run Tests" immediately conveys the purpose of the workflow.


3-8: Trigger Events are Configured Appropriately
Pushes and pull requests to the "main" branch will trigger this workflow as intended.


9-12: Effective Concurrency Configuration
The concurrency block is set up to cancel in-progress runs for the same branch or pull request, which helps in saving resources and avoiding duplicate executions.


35-37: Matrix Strategy Review for API Level
The matrix defines an API level as [35-ext15]. Please double-check that this identifier (35-ext15) is valid for the intended Android testing environment. If this value is custom, ensure that all downstream configuration (e.g., in AVD creation) supports it.


39-40: Repository Checkout is Correctly Implemented
The use of actions/checkout@v4 ensures the repository is available for the job.


41-46: KVM Configuration for Emulator Acceleration is Properly Set Up
Enabling KVM via udev rules and reloading them is correctly implemented to support Android emulator performance.


47-49: Granting Execute Permission for gradlew is Appropriate
The explicit chmod +x gradlew step is correctly applied in this job to ensure that the Gradle wrapper can be executed.


50-52: Gradle Cache Setup is Configured
Leveraging gradle/actions/setup-gradle@v3 for caching dependencies should improve performance. Verify that the cache hit/miss behavior meets your expectations over time.


53-61: AVD Cache Key Using Matrix Variable
The AVD cache step uses the key avd-${{ matrix.api-level }}, relying on the matrix strategy. This approach was flagged earlier; please confirm that this dynamic key works as intended in all cases.


72-80: Execution of Instrumented Android Tests is Implemented Properly
The final step runs connected Android tests via the reactivecircus/android-emulator-runner action with the expected parameters. Ensure that all emulator options (e.g., -no-snapshot-save, -no-window, etc.) are optimal for your CI environment.
