# Moodle Testing and Quality Assurance

## Purpose
Ensure all PHP code is robust, reliable, and maintainable through comprehensive testing and quality practices.

## Instructions
- Write unit tests using Moodle's PHPUnit integration for all new code
- Organize tests in the `tests/` directory of each plugin or component
- Use data providers for testing multiple scenarios
- Mock dependencies using Moodle's test helpers
- Ensure code coverage for critical paths and edge cases
- Use Behat for acceptance and integration tests where UI is involved
- Run tests automatically before merging code
- Fix or skip failing tests only with documented reasons

## Examples
```php
// File: ./mod/myplugin/tests/myplugin_test.php
class mod_myplugin_testcase extends advanced_testcase {
    public function test_plugin_returns_expected_value() {
        $this->resetAfterTest(true);
        $result = myplugin_function();
        $this->assertEquals('expected', $result);
    }
}
```

## Exceptions
- Legacy code may be covered by integration tests only
- Third-party libraries may use their own test suites
