Build Test Verify

Running Tests

IMPORTANT: The app module uses the standard flavor. Always use testStandardDebugUnitTest, NOT testDebugUnitTest.

IMPORTANT: Always pipe test output through a filter that captures failures on the first run. Gradle suppresses detailed failure output by default, so use 2>&1 | grep -E "FAILED|BUILD|expected:|actual:|AssertionError|failures" | head -30 to see pass/fail results and assertion details without needing a second run.

# App module tests (correct flavor!)
./gradlew app:testStandardDebugUnitTest 2>&1 | grep -E "FAILED|BUILD|expected:|actual:|AssertionError|failures" | head -30

# Run specific test classes
./gradlew app:testStandardDebugUnitTest --tests "com.x8bit.bitwarden.SomeTest" 2>&1 | grep -E "FAILED|BUILD|expected:|actual:|AssertionError|failures" | head -30

# Run all unit tests across all modules
./gradlew test

# Individual shared modules (no flavor needed)
./gradlew :core:test
./gradlew :data:test
./gradlew :network:test
./gradlew :ui:test

# Authenticator module
./gradlew authenticator:testStandardDebugUnitTest

Reading Test Reports

If you need full failure details beyond what grep captures, check the HTML test report:

# After a test run, open the report at:
# app/build/reports/tests/testStandardDebugUnitTest/index.html
# Or read individual failure XML:
find app/build/test-results -name "*.xml" -exec grep -l "failure" {} \;

Test Structure

app/src/test/                    # App unit tests
app/src/testFixtures/            # App test utilities
core/src/testFixtures/           # Core test utilities (FakeDispatcherManager)
data/src/testFixtures/           # Data test utilities (FakeSharedPreferences)
network/src/testFixtures/        # Network test utilities (BaseServiceTest)
ui/src/testFixtures/             # UI test utilities (BaseViewModelTest, BaseComposeTest)

Test Quick Reference

• Dispatcher Control: FakeDispatcherManager from :core:testFixtures
• MockK: mockk<T> { every { } returns }, coEvery { } for suspend
• Flow Testing: Turbine with stateEventFlow() helper from BaseViewModelTest
• Time Control: Inject Clock for deterministic time testing

Lint & Static Analysis

IMPORTANT: Prefer running detekt on modified files only — a full project scan is slow and unnecessary during development. The project supports a -Pprecommit=true flag that limits detekt to staged files.

IMPORTANT: Always pipe detekt output through a filter to capture errors on the first run. Detekt prints violation details to stderr/stdout but Gradle can obscure them. Use the grep pattern below to see violations immediately.

# Detekt on staged files only (preferred during development)
git add -u && ./gradlew -Pprecommit=true detekt 2>&1 | grep -E "FAILED|BUILD|Line |Rule |Signature|detekt" | head -40

# Detekt on all files (full scan, use sparingly)
./gradlew detekt 2>&1 | grep -E "FAILED|BUILD|Line |Rule |Signature|detekt" | head -40

# Android Lint
./gradlew lint

# Full validation suite (detekt + lint + tests + coverage)
./fastlane check

How -Pprecommit=true Works

The root build.gradle.kts configures detekt tasks to use git diff --name-only --cached when this property is set, limiting analysis to staged files only. This is the same mechanism used by the project's pre-commit hook. Stage your changes with git add before running.
