Watir
Watir
An open-source Ruby library for automating tests. Watir interacts with a browser the same way people do, clicking links, filling out forms, and validating text. It requires Ruby 2.6+ and Selenium 4.0 which was just released last week. It’s been a long road since Watir 6.0 was released almost 5 years ago. That version was a substantial reenvision of Watir’s default approach to automation, especially as it relates to Selenium. It was designed to combine the original philosophy of Watir with the power of Selenium. Watir 7 is mostly just a much more stable and performant implementation of that vision. When developing a gem intended to be used with Watir, you can run your code with WatirSpec to make sure that requiring your code does not break something else in Watir. Watir code is tested on Linux with the latest versions of supported browsers and all active Ruby versions. Watir code is run through Coveralls to encourage PRs to ensure all paths in their code have tests associated with them.Starting Price: Free -
