Puth
Puth is a nice browser testing framework with focus on stability, performance and extensive feedback.
Why use Puth
Puth solves the problem of being able to run browser tests in any programming language. It does this by providing a very simple api that can be used to control Puth.
Extensible
You can easily extend Puth with plugins. You need a special function? Then write your own plugin. It's really easy, I promise! :)
