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?

Solution 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.

Solution 2

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);
}

Solution 3

Since Laravel 5.5 to test redirect you can use assertRedirect:

/** @test */
public function store_creates_claim()
{
    $response = $this->post(route('claims.store'), [
        'first_name' => 'Joe',
    ]);

    $response->assertRedirect(route('claims.index'));
}

Solution 4

Laravel 8 tested

$response = $this->post'/contact', ['email' => '[email protected]', 'message' => "lorem ipsum"]);

$response->assertStatus(302);
$response->assertRedirect('home');

$this->followRedirects($response)->assertSee('.success-message');
//or
$this->followRedirects($response)->assertSee('Ok!');

Worked for me, hoped it helps.
