The best thing about Staf is that it helps us in automating our application tests. Also, the UI testing feature is very useful for any development team because it allows them to do UI automation without knowing how to use Selenium IDE or WebDriver. I would like to see more features and improvements in this product. It's a good tool as it provides a lot of benefits when compared with other products. We have been using Staf for UI and functional automation. Its easy to set up and the setup of test cases are simple and understandable. We have been using this tool for Selenium Webdriver Ui Automation and Selenium Functional Automation.
