The Power of Tests

Someone has written a fantastic article on unit-testing Ruby applications.

The Power of Tests:

My belief is that unit testing is for everyone and, in fact, I’ll go so far as to say that I believe becoming a test-driven developer is the single best change a programmer can make in their day to day routine.

The artistic explains succintly what five virtues of unit testing are.

Then it jumps into giving great examples of how to write really useful tests in Ruby.

These examples are primo. Well worth reading if you are a Ruby programmer.
