Laravel testing requests

Question

I'm working on a large Laravel app, currently on v8.45.1 which has never had tests, so I'm working to get it to a point where we can start writing unit & feature tests.

I'm hitting an issue where the two request classes ( App\\Core\\Request and App\\Core\\FormRequest ) both use a trait RequestTrait which holds a set of utility methods.

This obviously works fine in local/staging/production, but when I run the test suite it complains that none of the methods provided by the trait exist:

Method Illuminate\Http\Request::isFromTrustedSource does not exist.

They are being called in various places as Request::isFromTrustedSource() or request()->isFromTrustedSource() .

I can imagine that when running the app in the test environment, there may be differences to the request. Is it using a different class, or does the trait not apply for some reason?

Answer 1

I think, I found your problem - App\\Core\\Request extends Illuminate\\Http\\Request and in index.php you use App\\Core\\Request

The problem is in Illuminate\\Foundation\\Testing\\Concerns\\MakesHttpRequests::call()

When you use $this->get(...) in test suite - this method bootstrap app with standard request - not with your App\\Core\\Request

You can override this method in base tests/TestCase.php and pass your own request.

Unfortunately, it has no contract, than you cannot work with this through $this->app->bind()

Something like this:

class TestCase extends BaseTestCase
{
    public function call($method, $uri, $parameters = [], $cookies = [], $files = [], $server = [], $content = null)
    {
    //other code
    $response = $kernel->handle(
        $request = \App\Core\Request::createFromBase($symfonyRequest)
    );
    //other code
    }
}
