Basic usage

Use $this->makeClient to create a Client object. Client is a Symfony class that can simulate HTTP requests to your controllers and then inspect the results. It is covered by the functional tests section of the Symfony documentation.

After making a request, use assertStatusCode to verify the HTTP status code. If it fails it will display the last exception message or validation errors encountered by the Client object.

If you are expecting validation errors, test them with assertValidationErrors.

use AlexisLefebvre\TestBundle\Test\WebTestCase;

class MyControllerTest extends WebTestCase
{
    public function testContact()
    {
        $client = $this->makeClient();
        $crawler = $client->request('GET', '/contact');
        $this->assertStatusCode(200, $client);

        $form = $crawler->selectButton('Submit')->form();
        $crawler = $client->submit($form);

        // We should get a validation error for the empty fields.
        $this->assertStatusCode(200, $client);
        $this->assertValidationErrors(['data.email', 'data.message'], $client->getContainer());

        // Try again with with the fields filled out.
        $form = $crawler->selectButton('Submit')->form();
        $form->setValues(['contact[email]' => 'nobody@example.com', 'contact[message]' => 'Hello']);
        $client->submit($form);
        $this->assertStatusCode(302, $client);
    }
}

Methods

Check HTTP status codes

isSuccessful()

Check that the request succedded:

$client = $this->makeClient();
$client->request('GET', '/contact');

// Successful HTTP request
$this->isSuccessful($client->getResponse());

Add false as the second argument in order to check that the request failed:

$client = $this->makeClient();
$client->request('GET', '/error');

// Request returned an error
$this->isSuccessful($client->getResponse(), false);

In order to test more specific status codes, use assertStatusCode():

assertStatusCode()

Check the HTTP status code from the request:

$client = $this->makeClient();
$client->request('GET', '/contact');

// Standard response for successful HTTP request
$this->assertStatusCode(302, $client);

Get Crawler or content

fetchCrawler()

Get a Crawler instance from an URL:

$crawler = $this->fetchCrawler('/contact');

// There is one <body> tag
$this->assertSame(
    1,
    $crawler->filter('html > body')->count()
);
fetchContent()

Get the content of an URL:

$content = $this->fetchContent('/contact');

// `filter()` can't be used since the output is HTML code, check the content directly
$this->assertContains(
    '<h1>AlexisLefebvreTestBundle</h1>',
    $content
);

Routing

getURL()

Generate an URL from a route:

$path = $this->getUrl(
    'route_name',
    array(
        'argument_1' => 'liip',
        'argument_2' => 'test',
    )
);

$client = $this->makeClient();
$client->request('GET', $path);

$this->isSuccessful($client->getResponse());
