Laravel - Testing what happens after a redirect

Question

I have a controller that after submitting a email, performs a redirect to the home, like this:

return Redirect::route('home')->with("message", "Ok!"); 

I am writing the tests for it, and I am not sure how to make phpunit to follow the redirect, to test the success message:

public function testMessageSucceeds() {     $crawler = $this->client->request('POST', '/contact', ['email' => '[email protected]', 'message' => "lorem ipsum"]);      $this->assertResponseStatus(302);     $this->assertRedirectedToRoute('home');      $message = $crawler->filter('.success-message');      // Here it fails     $this->assertCount(1, $message); } 

If I substitute the code on the controller for this, and I remove the first 2 asserts, it works

Session::flash('message', 'Ok!'); return $this->makeView('staticPages.home'); 

But I would like to use the Redirect::route. Is there a way to make PHPUnit to follow the redirect?

Answer 1

You can get PHPUnit to follow redirects with:

Laravel >= 5.5.19:

$this->followingRedirects(); 

Laravel < 5.4.12:

$this->followRedirects(); 

Usage:

$response = $this->followingRedirects()     ->post('/login', ['email' => '[email protected]'])     ->assertStatus(200); 

Note: This needs to be set explicitly for each request.

For versions between these two:

See https://github.com/laravel/framework/issues/18016#issuecomment-322401713 for a workaround.

You can tell crawler to follow a redirect this way:

$crawler = $this->client->followRedirect(); 

so in your case that would be something like:

public function testMessageSucceeds() {     $this->client->request('POST', '/contact', ['email' => '[email protected]', 'message' => "lorem ipsum"]);      $this->assertResponseStatus(302);     $this->assertRedirectedToRoute('home');      $crawler = $this->client->followRedirect();      $message = $crawler->filter('.success-message');      $this->assertCount(1, $message); }
