Track: Test Strategy, Process and Design
Test metrics have long been used to advise on progress of testing initiatives; however, how many projects actually use these beyond the standard reporting process? Metrics that can be used to analyse trends are not only valuable as a record of progress to date but also for forecasting forward and modelling “what if” scenarios. For example, if a 3-person test team with 100 test cases to execute passes an average (given that test cases are invariably of unequal length) of 5 test cases per day at Day 3 of a test execution cycle, it equates to a further ~17 days of testing if current progress can be maintained. However what if the rate slows because a higher than previous level of defects is experienced or one of the team goes down sick? Or the business analysts graciously accept additional requirements that lead to a bunch of more test cases to do?
This session will show attendees which metrics to capture and which ones to develop, how to turn that information into trend analyses, and then discuss application of methods and techniques to not only forecast progress but also model the effects of both positive and negative influences on the test effort.
