Laravel login test failed in phpunit

Question

I am trying to do login test by phpunit in laravel. I have 5.5 so visit method is not supported. Here is what I am doing

public function testLoginPost(){
Session::start();

$response = $this->call('POST', 'login', [
    'email' => '[email protected]',
    'password' => '123456',
    '_token' => csrf_token()
]);
$this->assertEquals(200, $response->getStatusCode());
$this->assertEquals('auth.login', $response->original->name());}

```

c:\wamp64\www\fundtheneedy\tests\Unit>phpunit Fundtheneedy
PHPUnit 6.5.8 by Sebastian Bergmann and contributors.

There was 1 failure:

Answer 1

If you purely look at the response code it will always be 302 which is the response code for a URL Redirect as it will redirect regardless whether or not it fails.

You can instead look at whether or not there are errors in the session which is a bit of a workaround mentioned in this post here.

$response->assertSessionMissing('errors');

Or use the inverse

$response->assertSessionHasErrors();

Answer 2

Given you'll always be redirected, regardless of a successful or unsuccessful login, you'll have to assert the response you got.

To test a successful login, you would do:

$response->assertStatus(302);
$response->assertRedirect('http://your-website.com/user/dashboard');

To test an unsuccessful login, you would do:

$response->assertStatus(302);
$response->assertRedirect('http://your-website.com/auth/login');

That should be enough.

PS: Edit the urls to match whatever you have, obviously.
