QA professionals, testers, and developers are constantly learning new tools, tech stacks, and development practices. When they’re told they have to learn accessibility, it can often feel like an unwelcome and overwhelming disruption, slowing them down and forcing them to test and rewrite what they thought was perfectly good code. The good news is accessibility tools are more tester-friendly than ever.

Ten years ago I saw a Selenium test that could click on a capital "I" that was one pixel wide. I was not capable of clicking on it myself. Around that time, a lot of people began using phrases like "End to end is further than you think." Simulators and emulators, after all, could not simulate heat, poor memory management, low power, and other problems. Then again, that was ten years ago.

A common complaint that I hear is: “My tests run a lot faster locally than on Sauce Labs.” Sauce Labs is in the cloud and not in your local network, so it makes sense that any given test is going to have some amount of slowdown. The advantage of Sauce Labs is that you can make up this difference by scaling up the number of tests you run at the same time.
