S-Curves and the Zero Bug Bounce: Plotting the Way to Better Testing

[presentation]

Shaun Bradshaw, Questcon Technologies, A Division of Howard Systems Intl.
Summary: 

The use of objective test metrics is an important step toward improving your ability to effectively manage any test effort. With the two test metrics-the S-Curve and Zero Bug Bounce-you can easily track the progress of the test effort. Learn to graph the S-Curve, showing cumulative test cases planned, attempted, and completed over time. Keep track of the Bug Bounce-the number of open bugs at the end of a period (usually one to several days)-and especially Zero Bug Bounce-the first time development has resolved all the bugs raised by the testers and there are no active outstanding issues. Improve your ability to communicate to the project team test results and test needs and make better decisions about when your application is ready to ship.

  • Derive a theoretical and actual S-Curve for test cases using historic and current data
  • Use the Zero Bug Bounce for tracking defect correction activities
  • Assess the risk of component and application failure prior to release
