Do you know any open software projects that had particularly interesting / well written unit tests ?
Writing unit tests often feels odd to me, because it seems either too random, too dense, to sparse, .. It would be great to read some real world examples (rather than books, library example code etc)..
I’ve found this blog post by Misko Hevery to be very useful, especially since he includes links to his actual source code with very well-written unit tests.
Update: Unfortunately, the links in his post are broken now. However, you can find the current source file with a search at http://code.google.com/p/testability-explorer/source/browse/trunk/testability-explorer/src/test/java/com/google/test/metric/collection/KeyedMultiStackTest.java.
