Common Software Errors – Checklist

I have been referring to this fantastic resource for a couple of years. It’s the Common Software Errors Appendix on Testing Computer Software by Dr. Cem Kaner. Appendix : Common Software Errors (

I have often referred this to my friends but this 89-page document often appears to be a long read for most people. Now, I have decided to convert this into a checklist for me or anyone who wants to leverage the power of these common software errors to assist their testing.

Disclaimer: All credits for these points go to Dr. Cem Kaner. I have just converted them to checklist pointers for quick use.

Pro Tip: The webpage will save the status of the checklist until you reset the page cache or a timeout happens (180 days). So, you can use this as a workbook too.
