Cannot run any of HTTP tests with Laravel plugin

[maximal]

Hi there!

We’re trying to setup basic Pest tests with Laravel plugin, and cannot run any of ->get(...)->->assertStatus(...) tests.

composer.json:

{
	// ... ... ...
	"require-dev": {
		// ... ... ...
		"pestphp/pest": "^2.19",
		"pestphp/pest-plugin-laravel": "^2.2",
		"roave/security-advisories": "dev-latest",
		"spatie/laravel-ignition": "^2.2",
		// ... ... ...
	},
	"minimum-stability": "stable",
	"prefer-stable": true,
	"config": {
		"optimize-autoloader": true,
		"preferred-install": "dist",
		"sort-packages": true,
		"allow-plugins": {
			"php-http/discovery": true,
			"pestphp/pest-plugin": true
		}
	},
	// ... ... ...
}

  Tests:    1 failed, 3 passed (3 assertions)

I have tried all of the combinations:

//uses(Tests\TestCase::class)->in('Feature');
//uses(Tests\TestCase::class)->in('Unit');
//uses(Tests\TestCase::class)->in(__DIR__);
uses(Tests\TestCase::class);

The only difference is the error message:

Call to undefined method PHPUnit\Framework\TestCase::get()
or
Call to undefined method Tests\TestCase::get()

Could anybody please help us with that?

Your tests/TestCase.php needs to extend the Laravel testcase. 👍🏻

Replace the use of PHPUnit\Framework\TestCase with Illuminate\Foundation\Testing\TestCase and it should work. 🙂

<?php

namespace Tests;

use Illuminate\Foundation\Testing\TestCase as BaseTestCase;

abstract class TestCase extends BaseTestCase
{
	//
}

Then i get:

Fatal error: Class P\Tests\Unit\ExampleTest contains 1 abstract method and must therefore be declared abstract or implement the remaining methods (Illuminate\Foundation\Testing\TestCase::createApplication) in /.../vendor/pestphp/pest/src/Factories/TestCaseFactory.php(196) : eval()'d code on line 11.

tests/TestCase.php:

<?php

namespace Tests;

//use PHPUnit\Framework\TestCase as BaseTestCase;
use Illuminate\Foundation\Testing\TestCase as BaseTestCase;

abstract class TestCase extends BaseTestCase
{
	//
}

tests/Pest.php

// ... ... ...

uses(Tests\TestCase::class)->in('Feature');
uses(Tests\TestCase::class)->in('Unit');
//uses(Tests\TestCase::class)->in(__DIR__);
uses(Tests\TestCase::class);

Are you adding tests to an existing Laravel app? 🤔 There should be an existing TestCase.php which looks like this:

<?php

namespace Tests;

use Illuminate\Foundation\Testing\TestCase as BaseTestCase;

abstract class TestCase extends BaseTestCase
{
    use CreatesApplication;
}

And a CreatesApplication.php which looks like this:

<?php

namespace Tests;

use Illuminate\Contracts\Console\Kernel;
use Illuminate\Foundation\Application;

trait CreatesApplication
{
    public function createApplication(): Application
    {
        $app = require __DIR__.'/../bootstrap/app.php';

        $app->make(Kernel::class)->bootstrap();

        return $app;
    }
}

Try using those files, and it should all work. 👍🏻

I run pest --init in an existing Laravel app, but without tests directory. Your solution works. Thanks!

The final solution is:

1. Have CreatesApplication.php: https://github.com/laravel/laravel/blob/10.x/tests/CreatesApplication.php
2. In tests/Pest.php:

   uses(Tests\TestCase::class)->in('Feature');
   uses(Tests\TestCase::class)->in('Unit');

3. In tests/TestCase.php:

   use Illuminate\Foundation\Testing\TestCase as BaseTestCase;
   
   abstract class TestCase extends BaseTestCase
   {
   	use CreatesApplication;
   	//
   }

Thank you very-very much, @owenvoke!
4. In tests/Unit/ExampleTest.php:

it('has home')
	->get('http://localhost/')
	->assertStatus(302);

Good luck with your tests! 🥳
