Here is example how you may test your Slim application: <a href="https://github.com/mac2000/SlimTestable">https://github.com/mac2000/SlimTestable</a> Suppose we have simple application: <pre><code><?php use Slim\Slim; require_once 'vendor/autoload.php'; $app = new Slim(); $app->get('/', function(){ echo 'home'; })->name('home'); $app->get('/hello/:name', function($name){ echo "hello $name"; })->name('hello'); $app->map('/login', function() use($app) { if($app->request()->params('login')) { $app->flash('success', 'Successfully logged in'); $app->redirect($app->urlFor('hello', array('name' => $app->request()->params('login')))); } else { $app->flash('error', 'Wrong login'); $app->redirect($app->urlFor('home')); } })->via('GET', 'POST'); $app->run(); </code></pre> How do we test it? Create <code>App</code> class: <pre><code><?php // src/App.php use Slim\Slim; class App extends Slim { function __construct(array $userSettings = array()) { parent::__construct($userSettings); $this->get('/', function(){ echo 'home'; })->name('home'); $this->get('/hello/:name', function($name){ echo "hello $name"; })->name('hello'); $this->map('/login', function() { if($this->request()->params('login')) { $this->flash('success', 'Successfully logged in'); $this->redirect($this->urlFor('hello', array('name' => $this->request()->params('login')))); } else { $this->flash('error', 'Wrong login'); $this->redirect($this->urlFor('home')); } })->via('GET', 'POST'); } /** * @return \Slim\Http\Response */ public function invoke() { $this->middleware[0]->call(); $this->response()->finalize(); return $this->response(); } } </code></pre> Notice that we move all our routes to new class constructor, also notice new <code>invoke</code> method, which do the same as <code>run</code> method except it returns response rather than echoing it out. Now your <code>index.php</code> file might be like this one: <pre><code><?php require_once 'vendor/autoload.php'; $app = new App(); $app->run(); </code></pre> And now it is time for tests: <pre><code><?php // tests/ExampleTest.php use Slim\Environment; class ExampleTest extends PHPUnit_Framework_TestCase { private $app; public function setUp() { $_SESSION = array(); $this->app = new App(); } public function testHome() { Environment::mock(array( 'PATH_INFO' => '/' )); $response = $this->app->invoke(); $this->assertContains('home', $response->getBody()); } public function testHello() { Environment::mock(array( 'PATH_INFO' => '/hello/world' )); $response = $this->app->invoke(); $this->assertTrue($response->isOk()); $this->assertContains('hello world', $response->getBody()); } public function testNotFound() { Environment::mock(array( 'PATH_INFO' => '/not-exists' )); $response = $this->app->invoke(); $this->assertTrue($response->isNotFound()); } public function testLogin() { Environment::mock(array( 'PATH_INFO' => '/login' )); $response = $this->app->invoke(); $this->assertTrue($response->isRedirect()); $this->assertEquals('Wrong login', $_SESSION['slim.flash']['error']); $this->assertEquals('/', $response->headers()->get('Location')); } public function testPostLogin() { Environment::mock(array( 'REQUEST_METHOD' => 'POST', 'PATH_INFO' => '/login', 'slim.input' => 'login=world' )); $response = $this->app->invoke(); $this->assertTrue($response->isRedirect()); $this->assertEquals('Successfully logged in', $_SESSION['slim.flash']['success']); $this->assertEquals('/hello/world', $response->headers()->get('Location')); } public function testGetLogin() { Environment::mock(array( 'PATH_INFO' => '/login', 'QUERY_STRING' => 'login=world' )); $response = $this->app->invoke(); $this->assertTrue($response->isRedirect()); $this->assertEquals('Successfully logged in', $_SESSION['slim.flash']['success']); $this->assertEquals('/hello/world', $response->headers()->get('Location')); } } </code></pre> You should notice few things: While setting up test we are creating <code>$_SESSION</code> array for test purposes and instantiate our <code>App</code> class object. In tests rather than <code>run</code> we are calling <code>invoke</code> which do the same, but returns response object. <code>Environment::mock</code> used to mock requests which are processed with our application.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
