Yes please do. Imagine the following:

We no longer generate `feeds.rake` but `feeds_tasks.rake`. Now the previous test fails, we update it and everything is good. Except that `test_task_on_revoke` is no useless. It's my habit to try to avoid `assert_no_X` stuff if possible. If I have to use it, I like to make sure that I know when I need to adjust the test.
