Absolutely. In fact, this should be the norm. When you consider edge cases
and a good sampling of non-edge cases, the unit test can quickly outgrow
the code being tested.

It may seem like a lot of work, but that work continues to pay off
everytime you run the tests, especially after code changes or
refactorings.
