# Testing
> Test chain: PHP standalone, PHPStan, and JS (Mocha)
---
The full chain runs with:
```bash
npm test
```
which executes `test:php` → `analyse:php` → `test:js`, each step required to pass before the next runs.
## JavaScript (Mocha + jsdom)
```bash
npm run test:js
# mocha 'resources/js/tests/**/*.test.js' --require jsdom-global/register
```
## PHP standalone unit tests
```bash
npm run test:php
# runs every tests/test-*.php with the system PHP — no webtrees install, no DB
```

## Smoke tests (need webtrees + DB)
These exercise a real installation and are **not** part of `npm test`:

php tests/smoke-text-tag-collector.php [limit]
php tests/smoke-migration5.php
php tests/p1-measure.php [--tree=]
```
