TYPO3 Testing Skill

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

Test Type Selection

Type Use When Speed
Unit Pure logic, no DB, validators, utilities Fast (ms)
Functional DB interactions, repositories, controllers Medium (s)
Architecture Layer constraints, dependency rules (phpat) Fast (ms)
E2E (Playwright) User workflows, browser, accessibility Slow (s-min)
Fuzz Security, parsers, malformed input Manual
Crypto Encryption, secrets, key management Fast (ms)
Mutation Test quality verification, 70%+ coverage CI/Release

Commands

# Setup infrastructure
scripts/setup-testing.sh [--with-e2e]

# Run tests via runTests.sh
Build/Scripts/runTests.sh -s unit
Build/Scripts/runTests.sh -s functional
Build/Scripts/runTests.sh -s architecture
Build/Scripts/runTests.sh -s e2e

# Quality tools
Build/Scripts/runTests.sh -s lint
Build/Scripts/runTests.sh -s phpstan
Build/Scripts/runTests.sh -s mutation

Scoring

Criterion Requirement
Unit tests Required, 70%+ coverage
Functional tests Required for DB operations
Architecture tests phpat required for full points
PHPStan Level 10 (max)

Note: Full conformance requires phpat architecture tests enforcing layer boundaries.
