Create Unit Test

This skill guides the creation of unit tests to ensuring consistency and correctness.

Workflow

  1. Analyze and Plan:

    • Goal: Understand what needs testing.
    • Action: Examine the source code.
    • Action: Identify "happy path" cases (core functionality).
    • Action: Identify "error cases" and "edge cases" based on likelihood.
    • Action: Do not suggest implementation details unless asked; focus on behavior.

  2. Setup Test File:

    • Naming: [OriginalClassName]Test.kt.
    • Location: [module]/​src/​test/​java/[package/​path]/.
    • Runner: If testing Android components, you MUST use Robolectric.
    • Mocking: Prefer creating Fakes over Mocks or patches. Use Mocks only if Fakes are too complex.

  3. Implement Tests:

    • Write clear, descriptive test methods.
    • Follow the "Arrange-Act-Assert" pattern.
    • Ensure all resources (strings, themes) are properly mocked or provided via Robolectric.

  4. Run Tests:

    • Command: ./​gradlew :[module]:testDebugUnitTest
    • Example: ./​gradlew :database:testDebugUnitTest
    • Tip: Before any commit, run ./​gradlew testDebugUnitTest to ensure everything passes.

  5. Handle Failures:

    • Goal: Diagnose and fix issues.
    • Action: If a test fails, locate the full error report.
    • Path: [module]/​build/​test-results/​testDebugUnitTest/​TEST-[package.name.TestClassName].xml.
    • Example: app/​build/​test-results/​testDebugUnitTest/​TEST-com.anysoftkeyboard.janus.app.MainActivityTest.xml.

Guidelines

  • Consistency: Always place tests in the test source set, not androidTest (unless specifically writing instrumentation tests, which is rare for this skill).
  • Reliability: Avoid flaky tests. Ensure deterministic behavior.
