||A basic admin test case with the ability to easily dispatch admin
pages and take advantage of utility methods in the base Dewdrop
test case class.
||All admin test case classes implement this interface to ensure that all admin
test cases offer the same functionality. We can't handle this with inheritance
because we must inherit different classes for stock test cases and DB test
cases. Once we can rely on PHP 5.4.x, traits will help make this simpler.
||This helper is used by all admin test case classes to provide the ability
to easily get access to the tested component object and dispatch pages from
it. This is used to allow some "horizontal" reuse between the admin test
cases because we can't achieve the reuse with inheritance. PHPUnit has a
pre-defined hierarchy imposed by its DBUnit extension, so we need to compose
our additional functionality in this manner.
