Different browsers render applications differently, so web applications need to be able to detect on which browser they are running and adjust their app code accordingly. Successfully testing all browsers and all versions are no small feat which is exactly why Sauce Labs built their solution on Selenium. To enable QA teams to execute Selenium based automation suites on multiple permutations, operating systems, and versions, for multiple browsers and browser versions.
At first glance, this seems like we’re done and this is the perfect solution to achieve complete application matrix coverage. Unfortunately, nothing is that simple, and upon digging deeper, it is apparent that not all environments are available for certification. You will have some critical use case gaps, there’s no way around it. So what are they and how do you get around them?
