// Base class which contains a valid Browser*.  Lots of boilerplate to
// recycle between unit test classes.
//
// This class creates fake UI, file, and IO threads because many objects that
// are attached to the TestingProfile (and other objects) have traits that limit
// their destruction to certain threads. For example, the net::URLRequestContext
// can only be deleted on the IO thread; without this fake IO thread, the object
// would never be deleted and would report as a leak under Valgrind. Note that
// these are fake threads and they all share the same MessageLoop.
//
// TODO(jrg): move up a level (chrome/browser/ui/cocoa -->
// chrome/browser), and use in non-Mac unit tests such as
// back_forward_menu_model_unittest.cc,
// navigation_controller_unittest.cc, ..
