I've been reading Growing Object-Oriented Software, Guided by Tests. I write automated tests for my code, but I'm not especially good at it. Partly because I'm not very good at writing testable code. Which is partly because I don't usually code test first. My problem is that I know enough to know that I don't know enough!

Anyway, I decided I should try to clean up my act a little. I wanted to try using a mocking library. I did a few minutes of research and looked at a comparison between EasyMock and jMock. Then I ran across Mockito and it looked simple and easy to use.

I added the jar to my project and wrote my first test with it. No problems and very easy to use.

But it's never that easy. I ran my build, which uses Proguard, and got a ton of errors and warnings :-(

I probably could have fixed them, but I took the easy way out and just configured my build to exclude the tests. I only ever run them from Eclipse anyway. It's not the ideal solution but it'll do for now.

In the process I cleaned up my Ant build file. When I first created it I was even more ignorant about Ant and Java and Proguard than I am now.

I've revised a few more tests to use Mockito and I'm quite happy with it. If you're programming in Java and aren't using a mocking library, give it a try.
