The ComponentTester exposes a set of properties that can be handy when doing asserts or to stage a component in a specific way. Here's a list of what is available :
* element : The HTML element that gets rendered.
* viewModel : The view-model for the component.
* configure : The ComponentTester's configure method can be overwritten in order to set it up with custom configuration or get a reference to the container instance.
* dispose : Cleans up the DOM after a test has run.
* bind : Manually handles bind.
* unbind : Manually handles unbind.
* attached : Manually handles attached.
* detached : Manually handles detached.
* waitForElement and waitForElements : Waits until one or several elements are present / absent. See below.
