Tests for windows which remain in memory after they are closed. Window
objects, and everything they contain, should be freed from memory as soon
as the window closes. Not doing so is a significant memory leak, which may
or may not also appear in the leak summary at the end of a test run.
Failing one of these tests means that opening a window has created a strong
reference to it somewhere, typically in a service that lasts the lifetime
of the application such as the observer service or preferences service.
It's very likely that failing one of these tests will cause all of the
subsequent tests to also fail.
