Traits

If you are working with "getter-setter-traits" (aware-of components), then you can easily test those using the GetterSetterTraitTester.

Getter-Setter Trait

The trait in question must have the following methods defined:

set[property-name](?[type] $property);
get[property-name](): ?[type] ;
has[property-name](): bool ;
getDefault[property-name](): ?[type] ;

Trait Example

class NameTrait
{
    protected $name = null;

    public function setName(?string $name)
    {
        $this->name = $name;

        return $this;
    }

    public function getName(): ?string
    {
        if (!$this->hasName()) {
            $this->setName($this->getDefaultName());
        }
        return $this->name;
    }

    public function hasName(): bool
    {
        return isset($this->name);
    }

    public function getDefaultName(): ?string
    {
        return null;
    }    
}

Testing the Trait

To test the trait, use the assertGetterSetterTraitMethods method inside your test.

use Aedart\Testing\TestCases\UnitTestCase;
use Aedart\Testing\GetterSetterTraitTester;

class NameTraitTest extends UnitTestCase
{
    use GetterSetterTraitTester;

    /**
     * @test
     */
    public function canAssertTraitMethods()
    {
        $this->assertGetterSetterTraitMethods(
            NameTrait::class,
            $this->faker->name,
            $this->faker->name
        );
    }
}

Auto Generate Argument Data

As an alternative, you can allow the tester to automatically detect and generate argument data, based on the argument's type. To do so, use the assertTraitMethods method.

use Aedart\Testing\TestCases\UnitTestCase;
use Aedart\Testing\GetterSetterTraitTester;

class NameTraitTest extends UnitTestCase
{
    use GetterSetterTraitTester;

    /**
     * @test
     */
    public function canAssertTraitMethods()
    {
        $this->assertTraitMethods(NameTrait::class);
    }
}

WARNING

Method is only able to generate data for scalar-types and Mocks for objects. This feature should be considered experimental!
