Do you miss the old "withConsecutive" method in PHPUnit? This library solves that problem for you.
Via Composer (https://packagist.org/packages/eboreum/phpunit-with-consecutive-alternative):
composer install eboreum/phpunit-with-consecutive-alternative
Via GitHub:
git clone [email protected]:eboreum/phpunit-with-consecutive-alternative.git
Within a test method — i.e. a method inside a child of \PHPUnit\Framework\TestCase
— simply do the following:
use Eboreum\PhpunitWithConsecutiveAlternative\MethodCallExpectation;
use Eboreum\PhpunitWithConsecutiveAlternative\WillHandleConsecutiveCalls;
...
$object = $this->createMock(DateTime::class);
$willHandleConsecutiveCalls = new WillHandleConsecutiveCalls();
$willHandleConsecutiveCalls->expectConsecutiveCalls(
$object,
'setISODate',
new MethodCallExpectation($object, 1999, 42),
new MethodCallExpectation($object, 2000, 43, 2),
);
...
$this->assertSame($object, $object->setISODate(1999, 42));
$this->assertSame($object, $object->setISODate(2000, 43, 2));
Make your own (abstract) test case class and simply add a proxy method doing the above.
Example:
use Eboreum\PhpunitWithConsecutiveAlternative\MethodCallExpectation;
use Eboreum\PhpunitWithConsecutiveAlternative\WillHandleConsecutiveCalls;
use PHPUnit\Framework\MockObject\MockObject;
use PHPUnit\Framework\TestCase;
abstract class AbstractUnitTestCase extends TestCase
{
/**
* @param non-empty-string $methodName
*/
final public static function expectConsecutiveCalls(
MockObject $object,
string $methodName,
MethodCallExpectation ...$methodCallExpectations,
): void {
(new WillHandleConsecutiveCalls())->expectConsecutiveCalls($object, $methodName, ...$methodCallExpectations);
}
}
\PHPUnit\Framework\MockObject\Builder\InvocationMocker
and so — contrary to the original withConsecutive
— we place the above method on \PHPUnit\Framework\TestCase
instead.
- In simpler terms: You call a method on
\PHPUnit\Framework\TestCase
, with the mock as an argument, rather than calling a method on the mock itself. - This change is largely because PHPUnit utilizes the "final" keyword a lot on classes and does not support decorators, making extending (an instance of) InvocationMocker nigh-impossible (unless we do evil class-override things).
You can see some of the reasoning and discussion about it here: sebastianbergmann/phpunit#4026
The main reason @sebastianbergmann decided to remove withConsecutive
(and at
, by the way) was with the argument: Don't mock what you don't own. Sadly, the resource he links to in sebastianbergmann/phpunit#4026 — being https://thephp.cc/news/2021/04/do-not-mock-what-you-do-not-own — is now a 404 page. Sebastian is a fantastic person and I and many others greatly appreciate his work over the years. Truly! However, I for one disagree with the "Don't mock what you don't own" sentiment. If something is part of the public API — third-part or not — one should be able to and allowed to mock it. Period.
No convenient alternative has been provided in PHPUnit itself.
A core problem was the disjointed connection between arguments and their corresponding return values, as they would be provided in separate methods, i.e.:
withConsecutive
willReturnOnConsecutiveCalls
orwillReturn
In order to make this connection abundantly clear, the value-object class \Eboreum\PhpunitWithConsecutiveAlternative\MethodCallExpectation
has been implemented. Within it is stored a return value (required) and 0 or more arguments.
Notice: You may indeed use callbacks (i.e. \PHPUnit\Framework\TestCase->callback(...)
) for the arguments instead of the actual values.
See LICENSE
file. Basically: Use this library at your own risk.
