A complex program never works right the first time. It will most likely contain errors, also called 'bugs'. Discovering and correcting those bugs is easier if the program has been designed with testing in mind. This lesson explains the principles of test case selection and evaluation, and presents strategies for effective debugging. In addition it shows how to use logging and assertions. There are several topics to consider. Select from the following menu or use 'n' to move to the next exhibit.
