# Unit Tests

## Setup

```bash
# Install dependencies
composer install

# Run all tests
./vendor/bin/phpunit

# Run specific test file
./vendor/bin/phpunit tests/test-model-registry.php

# Run with testdox output
./vendor/bin/phpunit --testdox

# Generate coverage report
./vendor/bin/phpunit --testdox --coverage-html coverage
```

## Test Structure

| File | Class Under Test | Coverage |
|------|-----------------|----------|
| `test-model-registry.php` | `WPAW_Model_Registry` | Model defaults, validation, display names |

## Adding Tests

1. Create a new file in `tests/` with the naming convention `test-{class-name}.php`
2. Class name should be `Test_{ClassName}` extending `PHPUnit\Framework\TestCase`
3. Add the class require to `tests/bootstrap.php` if the class is not autoloaded
4. Run tests to verify

## Running Without Composer

If PHPUnit is installed globally:
```bash
phpunit --bootstrap tests/bootstrap.php tests/
```
