Good reporting and interface, but supports limited types of protocols and requires low-level script editing

It should have more interfaces. In terms of interfaces or protocols, what you can do with Rational is far limited as compared to other products out there. What it does, it does great, but it only gives you limited types of protocols. It supports between 8 to 15 types of protocols, whereas other test tools give you 20 to 30 types of protocols with which you can do testing and convert to script. It records Javascript-based scripts, and you got to know a little bit of Java to basically be able to edit them, but the level of editing you got to do is very low. I like that, but the ability to edit the script is not as good as Parasoft or LoadRunner, which have C-Script.

Automation test development becomes accessible and effective for functional testers

Tricentis Tosca is a codeless tool, making it easy for everyone to understand the transition of how to develop scenarios or test cases. In Tricentis Tosca, analyzing failures is straightforward because every time it fails somewhere, I get the screenshot, which helps me analyze how and why it failed. It has all the modules, including some pre-built ones that can be reused efficiently. Compared to other code tools such as Selenium, where I used to develop one script in one day, with Tricentis Tosca I can easily develop one script in four hours or three hours, saving four to five hours in a day.
