Knockout: MVVM

How your PHP represents your data

HTML with data-bind attributes

Two way binding of data and UI

The Demo

Knockout is TestableJavaScript!

• ViewModel must be a class

• Sinon is helpful for testing AJAX

Slim is Testable!

• Create your own App class

• Create an invoke method: public function invoke() { $this->middleware[0]->call(); $this->response()->finalize(); return $this->response(); }

RedBeanPHP isalmost Testable!

• Use in-memory sqlite:

public function setUp() { R::setup('sqlite::memory:'); require('seed.php'); }

public function tearDown() { R::close(); }
