Trying to test a controller action which uses the gotoRouteAndExit function of the redirector helper results in the test exiting silently; you are therefore unable to run any assertions after dispatch.
Not sure if this is a bug at all, or if it is whether it's in PHPUnit or ZF.
Further, I'm not sure of the utility of gotoRouteAndExit over gotoRoute - I probably shouldn't have been using it at all, frankly! It would be nice to have this documented.
gotoRouteAndExit() does that what it states, it calls exit()!
You can't use that method if you want to test your code.
