When you don't run your JUnit tests...
...bad things will happen
Here's my tip for the day. If you have a set of JUnit tests, always run them when delivering new code or changes to existing code. Brown's 1st law of JUnit testing says that when you don't run them for even the smallest of changes, bad things will happen. And that's exactly what happened to me today.
2 lines of code changed + a quick delivery that skipped the JUnit tests = a broken system
Note to self : always run your JUnit tests regardless of how trivial the change is. ;-)
