Phpunit Extensions Laravel Package

PHPUnit extensions

Utility classes to make unit testing life easier.

Features

withConsecutive

In PHPUnit 10 withConsecutive method was removed. To still be able to migrate existing codebases a replacement method:

PHPUnit <= 9.5:

$mock->method('myMethod')->withConsecutive([123, 'foobar'], [456]);

PHPUnit >= 9.6:

$mock->method('myMethod')->with(...consecutive([123, 'foobar'], [456]));

Symfony controller tests

Testing a Symfony controller internally invokes the dependency container. A utility class to mock these classes more easily.

use DR\PHPUnitExtensions\Symfony\AbstractControllerTestCase;

class MyControllerTest extends AbstractControllerTestCase 
{    
    public function myTest(): void 
    {
        $this->expectDenyAccessUnlessGranted('attribute', null, true);
        $this->expectGetUser(new User());
        $this->expectCreateForm(TextType::class);
        
        ($this->controller)();    
    }
    
    public function getController() {
        return new MyController();    
    }    
}

Methods

• expectGetUser
• expectIsGranted
• expectDenyAccessUnlessGranted
• expectCreateForm
• expectAddFlash
• expectGenerateUrl
• expectGenerateUrlWithConsecutive
• expectRedirectToRoute
• expectForward
• expectRender

Symfony ConstraintValidator tests

TestCase for testing Symfony ConstraintValidators.

use DR\PHPUnitExtensions\Symfony\AbstractConstraintValidatorTestCase;

class MyConstraintValidatorTest extends AbstractConstraintValidatorTestCase 
{    
    public function testValidate(): void
    {
        $this->expectBuildViolation($constraint->message, ['parameter' => 123])
            ->expectSetCode(789)
            ->expectAtPath('path')
            ->expectAddViolation();

        $this->validator->validate(123, $this->constraint);
    }
    
    protected function getValidator(): ConstraintValidator
    {
        return new MyConstraintValidator();
    }

    protected function getConstraint(): Constraint
    {
        return new MyConstraint();
    }
}

Methods

• assertHandlesIncorrectConstraintType
• expectNoViolations
• expectBuildViolation(): ConstraintViolationBuilderAssertion

ConstraintViolationBuilderAssertion

• expectSetInvalidValue
• expectSetPlural
• expectSetCode
• expectSetCause
• expectSetTranslationDomain
• expectSetParameters
• expectSetParameter
• expectSetParameterWithConsecutive
• expectAtPath
• expectAddViolation

ResponseAssertions trait

The ResponseAssertions trait provides a set of assertion methods designed to streamline the testing of Symfony HTTP responses. This trait includes methods for verifying the status code, response message content and specific types of responses such as JSON responses

Methods

• assertJsonResponse
• assertResponse
• assertResponseIsSuccessful
• assertResponseIsRedirection
• assertResponseIsClientError
• assertResponseIsServerError

ClockTestTrait

The ClockTestTrait provides a set of methods to manipulate the current time in tests. This trait will automatically freeze the time at the start of each test. The trait also provides methods to get the current time as timestamp or DateTimeImmutable object,

Methods

• self::time(): int
• self::now(): DateTimeImmutable
• self::sleep(int|float $seconds): void
• self::assertNow()
• self::assertSameTime()

ImageTestTrait

The ImageTestTrait provides methods to compare two images by binary string, SplFileInfo or resource. (Requires Imagick). Internally Imagick::compareImages() is used to compare the images and therefore supports various image formats such as PNG, JPEG, GIF, PDF and more.

Methods

• self::assertSameImage(string|SplFileInfo|resource, string|SplFileInfo|resource)
• self::assertNotSameImage(string|SplFileInfo|resource, string|SplFileInfo|resource)

PdfTestTrait

The PdfTestTrait provides methods to compare a TCPDF object against an image of binary string, SplFileInfo, resource or another TCPDF file. (Requires Imagick with ghostscript and TCPDF)

Methods

• self::assertSamePdf(string|SplFileInfo|resource|TCPDF, TCPDF)
• self::assertNotSamePdf(string|SplFileInfo|resource|TCPDF, TCPDF).

For both ImageTestTrait and PdfTestTrait:

The environment variable PHPUNIT_EXTENSIONS_IMAGE_DIFF_OUTPUT_PATH can be set to a directory where a diff.html will be generated which will show the differences. Optionally, the environment variable PHPUNIT_EXTENSIONS_IMAGE_DIFF_OUTPUT_URL can be set to inform the user where to find the outputted diff.html file. This is useful when running tests in a CI environment.
