Speaker: Mark Weiss

Topic: If it’s said a picture is worth a thousand words, could a screenshot detect a thousand defects? This is a talk around a much lesser known type of test automation. This testing goes by many different names, but one of the most common is Visual Differential Testing, or Visual Diff for short. It is the act of using screen captures and comparisons to find unexpected changes. In this talk, we’ll follow Mark Weiss’ experiences exploring Visual Diff testing of a web app. We’ll start the journey from its very beginning. What caused him to explore Visual Diff testing? Why’d he build his own framework? What are the pitfalls of doing so? This will be done by going through each iteration of his homegrown implementation and seeing the many mistakes and the many wins it has provided. By the end, you’ll hopefully know if Visual Diff testing is right for you and be able implement a version of it while avoiding many costly mistakes.
