# Testing {#developer-testing}

The extension includes a comprehensive test suite covering
unit tests, fuzz tests, functional tests, static analysis,
code style checks, JavaScript tests, end-to-end tests, and
mutation testing.

## Running tests {#running-tests}

**PHP test commands**

```bash
# Unit tests
composer ci:test:php:unit

# Fuzz tests
composer ci:test:php:fuzz

# Functional tests (requires MySQL)
composer ci:test:php:functional

# Static analysis (PHPStan level 10)
composer ci:test:php:phpstan

# Code style (PER-CS3.0)
composer ci:test:php:cgl

# Mutation testing (Infection, min-MSI 80%, covered-MSI 80%)
composer ci:mutation
```

**JavaScript and E2E test commands**

```bash
# JavaScript unit tests (Vitest)
npx vitest run

# E2E tests (Playwright); installs its own TYPO3 13 in containers
Build/Scripts/runTests.sh -s e2e

# ... the same against TYPO3 14
E2E_TYPO3_VERSION=14 Build/Scripts/runTests.sh -s e2e

# ... or against a TYPO3 that is already running
TYPO3_BASE_URL=https://your-typo3.local Build/Scripts/runTests.sh -s e2e
```

## The E2E environment {#the-e2e-environment}

`-s e2e` brings up everything the browser needs: MariaDB, a TYPO3
installed by Composer with this extension required from the checkout,
PHP-FPM and Apache, plus the Playwright container that drives them. The
instance lives in `.Build/e2e-typo3` and is thrown away when the suite
passes; a failed run keeps it, so the backend can be inspected
afterwards.

The specs only ever open `/typo3`. The frontend exists because
provisioning refuses to hand over an instance whose frontend does not
answer 200 — `e2e_provision_typoscript()` in
`Build/Scripts/runTests.conf` gives the root page just enough
TypoScript for that.

Docker is required. Nothing is installed on the host, and DDEV is not
involved.
