We also need to verify that our implementation matches the specifications we get from those user requirements.Īutomated testing can be applied to both validations and verifications. We need to validate that our user requirements actually solve the problems we set out to solve. You may have noticed that there are two labels on the feedback channel built into the V-model: verification and validation. The problem, at the end of the day, was not the time available for testing but rather the timing of the testing.
Inevitably, rushed fixes were merged at the last minute I learned to keep my calendar clear for a couple of weeks after big launches so that I could triage all of the issues we missed (or introduced) in our mad dashes to the finish.
Ultimately, I was never able to find the correct amount of time to allocate for QA. How long will this defect take to fix? How much will it impact the timeline? Will new bugs be introduced? How will we ensure each fix is verified with time to fix anything we broke while we were fixing the first thing? While building in time for manual testing reduced some stress in the final days of projects, there were still too many surprises.īuilding in time for QA testing is great in theory but quickly falls apart in practice once the first bug or defect is identified. If a project must be done by a certain date and testing will take a certain amount of time, then we can use that information to work backward and choose a due date for our project. In fact, if you haven’t, you are a unicorn and I would like to hear from you.Įarly stages in my software development career, I learned the importance of working backward from a deadline. Have you been involved in a software project that ran over budget and blew past every deadline? Of course, you have – we all have.
