Laravel test actingAs

i am trying to test one form of my website. This form is available only for logged in users. With the following code i get a failure. The html code which is returned is of the login page, so somehow the actingAs() method seems not to work ?

class AnalysesTest extends TestCase {

use DatabaseTransactions;

public function testSeeAddAnalysesForm()
{
    $pass = 'mypass';
    $user = $this->create_fake_user($pass);
    $this->actingAs($user)
    ->visit('analyses/create')
    ->see('Save');
}

protected function create_fake_user($pass) {
    $faker = Faker\Factory::create();
    return App\Models\User::create([
        'name' => $faker->name,
        'company' => $faker->name,
        'position' => 'Assistant',
        'email' => $faker->email,
        'phone' => $faker->phoneNumber,
        'status' => 1,
        'password' => $pass,
    ]);
}

}

The error I get is: Failed asserting that the page contains the HTML [Save]. Please check the content above.
