php laravel绑定嘲讽实例失败

Question

I try to mock a class with Mockery. I create a new Laravel projet.

I create the controller app/Http/Controllers/Mockcontroller.php with contents :

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class Mockcontroller extends Controller
{
    function get($id) {
        return 'FAILED';
    }
}

I want to mock the get() method, so I have modified the file tests/ExampleTest.php with this contents :

    <?php

    use Illuminate\Foundation\Testing\WithoutMiddleware;
    use Illuminate\Foundation\Testing\DatabaseMigrations;
    use Illuminate\Foundation\Testing\DatabaseTransactions;

    class ExampleTest extends TestCase
    {
        /**
         * A basic functional test example.
         *
         * @return void
         */
        public function testBasicExample()
        {
            $mock = Mockery::mock(App\Http\Controllers\Mockcontroller::class);
            $mock->shouldReceive('get')
                ->with(10)
                ->andReturn('SUCCESS');
            $this->app->instance(App\Http\Controllers\Mockcontroller::class, $mock);

            $ctrl = new App\Http\Controllers\Mockcontroller();
            dd($ctrl->get(10));


        }
    }

But when I run the following command :

vendor/bin/phpunit

I get this output

PHPUnit 5.7.5 by Sebastian Bergmann and contributors.

"FAILED"
zsh: exit 1     vendor/bin/phpunit

When I replace this line dd($ctrl->get(10)); by the following line :

dd($mock->get(10));

I get the right text : SUCCESS.

So, that's mock injection that failed.

Do you have a way to correctly inject my mock ?

Answer 1

With $ctrl = new App\\Http\\Controllers\\Mockcontroller(); you create a new instance of controller without using app container, and consequently the mock.

Since you set your mock as $this->app->instance(App\\Http\\Controllers\\Mockcontroller::class, $mock); you need to get is as $this->app->make(App\\Http\\Controllers\\Mockcontroller::class); , but to be completely honest, I don't see much sense in what you are doing.
