Laravel Testing login Credential using phpunit + multiprocess

Question

I'm pretty new on unit testing and I want to try to test my login page my Goal for this unit are : -> if it match in database -> redirect to route '/' -> if not -> redirect to route '/login'

<?php

namespace Tests\Feature;

use App\Domain\Core\Models\User;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Session;
use Tests\TestCase;
use Illuminate\Foundation\Testing\WithoutMiddleware;
use Illuminate\Foundation\Testing\DatabaseMigrations;
use Illuminate\Foundation\Testing\DatabaseTransactions;

class userTest extends TestCase
{
    use DatabaseMigrations;
    /**
     * A basic test example.
     *
     * @return void
     */
    public function testLoginTrue()
    {
        $credential = [
            'email' => '[email protected]',
            'password' => 'user'
        ];
         $this->post('login',$credential)->assertRedirect('/');
    }

    public function testLoginFalse()
    {
        $credential = [
            'email' => '[email protected]',
            'password' => 'usera'
        ];
        $this->post('login',$credential)->assertRedirect('/login');
    }
}

when I test on TestLoginTrue , its successfully return to '/' But when i try the TestLoginFalse ... it return same like TestLoginTrue, it should be stayed on '/login' route, Any Idea?

Plus I want to try to check if when I already login I couldn't access the login page so my initial idea is : public function testLoginTrue()

{
    $credential = [
        'email' => '[email protected]',
        'password' => 'user'
    ];
     $this->post('login',$credential)
         ->assertRedirect('/')
         ->get('/login')
         ->assertRedirect('/');
}

but... it returns

1) Tests\Feature\userTest::testLoginTrue BadMethodCallException: Method [get] does not exist on Redirect.

So how to do it correctly?

Thanks in advance

Answer 1

I am also a bit stuck with Laravel 5.4 testing follow redirects case.

As a workaround, you may check $response->assertSessionHasErrors(). This way it should work:

public function testLoginFalse()
{
    $credential = [
        'email' => '[email protected]',
        'password' => 'incorrectpass'
    ];

    $response = $this->post('login',$credential);

    $response->assertSessionHasErrors();
}

Also, in testLoginTrue() you may check, that session missing errors:

$response = $this->post('login',$credential);
$response->assertSessionMissing('errors');

Hope this helps!
