Regression Testing

Time after time I find that regression testing is a key to success. What is regression testing?

Regression Testing is testing your software after you've changed it to make sure you didn't break anything that was already fixed. Typcally it is automated. You run your tests to see if the program is working as specified.

I work a lot in Excel and I always compare the output of the current report to the ouput of the new report to make sure the numbers on the report are still correct. I'm amazed at how often I find problems before my users find them.

If you strat regression testing the quality of your software is guaranteed to improve.
