Generate controller test cases?

[beporter]

If possible, baking a controller class and its associated test class should produce a test suite that passes and covers the majority (if not all) of the baked controller. The bake process is fairly deterministic-- so the tests should likewise be predictable.

There may be issues in how much information we have about the controller when rendering the test class of course, but this topic warrants some research and experimentation. Anything to improve upon an empty test class with a bunch of ->markTestIncomplete()s.
