module:ct-component/testing/ComponentFixture(sXml, oModelFixture, oViewFixtureopt)

The ComponentFixture serves to create components using the ComponentFactory when these are required in the system under test.

In addition to creating and opening the component, the ComponentFixture defines several sub-fixtures to be added to the test runner, enabling the testing and manipulation of the view and presentation model of the component.
