Integration testing helpers for the Slim Framework

For a full example, please see the companion repo at there4/slim-unit-testing-example.

Example

Here's a test for a very simple endpoint that returns the version from the application config. We're asserting that Slim responded with a 200 and that the version matches what we expect.

class VersionTest extends LocalWebTestCase {
    public function testVersion() {
        $this->client->get('/version');
        $this->assertEquals(200, $this->client->response->status());
        $this->assertEquals($this->app->config('version'), $this->client->response->body());
    }
}

Here is an example on how to pass data to a POST endpoint in a test case and retrieve it later in the endpoint.
We are passing encoded JSON data in the body of the request.
The data is retrieved in the endpoint using $app->request->getBody().

// test file
class UserTest extends LocalWebTestCase {
    public function testVersion() {
        ......
        $data = array("user" => 1);
        $data = json_encode($data);
        $this->client->post('/user', $data);
        ......
    }
}

// endpoint file
.....
$app->post('/user', function() use ($app){
   .....
   $data = $app->request->getBody();
   $data = json_decode($data, true);
   ......
});

Example with DbUnit

If you wish to use Database fixture, use class WebDbTestCase. Caution: make sure the names you use for you fixture models won't conflict with your actual DB tables.

class LocalDbWebTestCase extends \There4\Slim\Test\WebDbTestCase {
	/**
	 * You must implement this method
	 * @return PHPUnit_Extensions_Database_DataSet_IDataSet
	 */
	public function getDataSet() {
		return $this->createFlatXMLDataSet(dirname(__FILE__) . DIRECTORY_SEPARATOR . 'fixture.xml');
	}
}

Setup

You'll need a bootstrap file for phpunit that can instantiate your Slim application. You can see [an example boostrap] in the sample app.

You'll implement your own getSlimInstance() method that returns an instance of your app by extending the WebTestCase helper.
