False Positive and False Negatives
      08/06/10 02:29 AM


I was wondering on some best practices/experiences on how you have handled False Positives/False Negatives.

False Positive - The test is marked as Failed, when the functionality is working.
False Negative - The test is marked as Passed, when the functionality is not working.

I am not very "concerned" with false positives since they would more or less be detected when the defect goes to the developer for debugging.

On the other hand, I am concerned with False Negatives.
I am not sure on how a Test Manager should handle false negatives.

The following are some of my thoughts -

1. Use different sample (test data)
2. Perform review of Test cases and Test Execution reports
3. Ensure that Test cases have detail
4. Consider Automation.
5. Define metrics from previous projects or current project (Look at defects coming from Production or next testing phase) and analyze why the false negative occurred.

I was wondering if anyone had other experiences or thoughts.
