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!
