Test Suites

• A test suite is a bunch of tests that get run on a piece of code.
• It is crucial to the development of good code.
• You can run functional tests, put in user keyboard input, compare screen shots, anything. The key is that it needs to be done automatically.
• On VB1 we had a check-in suite. That is, before you could submit code, you grabbed the write cookie and the current system. Built with your changes. Then ran the test suite. If you passed, you could submit the code and then give back the write cookie. It took 2 hours to run on a good machine.
• There was also a 2 week test cycle run on dozens of machines. This occasionally popped up old bugs that were then reactivated in raid.
• The test suite is the key component in Extreme Programming
