Helpers for PHP tests

Usage

AccessProtectedTrait

Helper to invoke methods and to get/set attributes values with private/protected visibility

class MyClassTest
{
    use Snailweb\Helpers\Tests\AccessProtectedTrait;

    public function testMyMethod()
    {
        // Invoke method
        $returnValue = $this->invokeMethod($object, 'methodName', ['arg1', 'arg2']);

        // Get attribute
        $attributeValue = $this->getAttribute($object, 'attributeName');

        // Set attribute
        $this->setAttribute($object, 'attributeName', $attributeValue);
    }
}

TestIteratorTrait

Helper to automatically apply Iterator tests for a class.

Requirements :

• The tested class must implement Iterator (that's the point of doing this ...)
• The tested class constructor must accept no parameters
• The test class must call setUpInterator() with class name, and optionally key name and array name (example shows defaults)

class MyClassTest extends TestCase
{
    use Snailweb\Helpers\Tests\TestIteratorTrait;
    
    public function setUp(): void
    {
        $this->setUpIterator(MyClass::class, 'key', 'array');
    }

    // Do your methods tests
    // ...
}

Note: if you need to test the constructor of your class you must do this :

class MyClassTest extends TestCase
{
    use Snailweb\Helpers\Tests\TestIteratorTrait{
        testConstruct as testIteratorConstruct;
    }
    
    public function setUp(): void
    {
        $this->setUpIterator(MyClass::class, 'key', 'array');
    }

    public function testConstruct()
    {
        $this->testIteratorConstruct();

        // Do your constructor tests
        // ...
    }

    // Do your methods tests
    // ...
}

TestSplSubjectTrait

Helper to automatically apply SplSubject tests for a class.

Requirements :

• The tested class must implement SplSubject (that's the point of doing this ...)
• The tested class constructor must accept no parameters
• The test class must call setUpSplSubject() with class name, and optionally observers name (example shows defaults)

class MyClassTest extends TestCase
{
    use Snailweb\Helpers\Tests\TestSplSubjectTrait;
    
    public function setUp(): void
    {
        $this->setUpSplSubject(MyClass::class, 'observers');
    }

    // Do your methods tests
    // ...
}
