How many times have your Selenium test suites run beautifully on one browser, only to fail when run in any other browser? This is an extremely common problem faced when incorporating cross-browser tests into your test runs. Not all browser drivers are created equally, but that doesn’t mean you can’t create a robust suite of cross-browser tests. This presentation shares strategies for making cross-browser tests invincible. It focuses on topics such as using as choosing the best locators for all browsers, explicit vs. implicit waits and how to leverage cloud-based testing tools. This presentation was given at O'Reilly Open Source Convention in May 2017.
