Mock AnyArgs PHPUnit Test

Unit tests are indeed super helpful but sometimes it is challenging to build them. As much as possible we want to keep them focused and simple.
In my case, I made a change to our company search service for it to support pagination. Hence I created a unit test that asserts for this.

However, the class I was mocking had other parameters. One in particular, the Search parameter which was a final class and could not be easily mocked.

Stepping back, I really did not need to mock this argument as the only argument I was interested on is the third one to ensure that I am passing the correct page.

Looking to make things simpler, I found AnyArgs.

use Mockery\Matcher\AnyArgs;

Here’s the final test snippet.

$this->mock(
    PerformCompanySearchAction::class,
    function (MockInterface $mock) {
        $mock->shouldReceive('__invoke')
            ->with(new AnyArgs(), 50, 2)
            ->once();
    }
);

💡 PHPUnit
There are times when you just want to assert for certain parameters only. Other params may not be relevant and sometimes they are down-right impossible to mock and can take up most of the code. (it may be a final class that is not easily mockable)

In cases like this you may opt to use for AnyArgs
