TYPO3 Testing Skill

Templates, scripts, and references for comprehensive TYPO3 extension testing.

Test Type Selection

Setup and Running Tests

# Setup
<skill-dir>/scripts/setup-testing.sh [--with-e2e]   # Initialize testing
<skill-dir>/scripts/validate-setup.sh               # Validate existing setup
<skill-dir>/scripts/generate-test.sh <Type> <Class> # Generate test file

# Run tests
Build/Scripts/runTests.sh -s unit          # Unit tests
Build/Scripts/runTests.sh -s functional    # Functional tests
Build/Scripts/runTests.sh -s architecture  # Architecture tests (phpat)
Build/Scripts/runTests.sh -s e2e           # E2E tests (Playwright)
Build/Scripts/runTests.sh -s lint          # Linting
Build/Scripts/runTests.sh -s phpstan       # Static analysis
Build/Scripts/runTests.sh -s mutation      # Mutation testing

After creating or modifying a test, always verify it fails before the fix and passes after. Run the full suite to ensure no regressions.
