We performed a comparison between IBM Rational Test Workbench and Katalon Studio based on real PeerSpot user reviews.
Find out what your peers are saying about Postman, Tricentis, Apache and others in API Testing Tools."This solution provides for API testing, functional UI testing, performance testing, and service virtualization."
"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."
"The basic framework and project organization is very good."
"User-friendly and a good solution."
"It supports multiple easy-to-learn languages."
"The initial setup is pretty straightforward and easy enough to complete."
"We are now performing automated testing in 15 minutes, which were previously taking a long time when doing it manually."
"Our clients have requested by all types of testing, including mobile, desktop, and API testing and all of those are covered by Katalon. I find that very valuable, very complete."
"The tool is easy to use. The product gives me the flexibility to use Selenium. I can also use my Java capabilities in the solution."
"This is a product that is well ahead of its immediate competition in features and functionality."
"There are a number of things that they can do to simplify the tools, but the most important thing that they need to do is simplify the installation."
"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."
"One improvement would be if it could support more programming languages such as JavaScript or Python. Right now, it is only on Groovy, which I think is not a too popular language."
"The Object Spy is rather frustrating to work with, so I tend not to use it."
"Its stability needs improvement."
"The tool's maintenance is very difficult since they do not follow call by value or call by reference. Due to this, any change happening is not reflected throughout all the test cases. There are some issues with data parameterization as well."
"The product is comparatively slow."
"Currently, I'm the only one who can use it because I have a Mac. It is giving a hard time to my team members who are on Linux. My team members are using Linux, and Katalon doesn't support Linux very well. It keeps on crashing. It crashes and shuts down almost every time they save their work, so they are not able to use it. It should have good support for Linux. We don't know what the problem is. If the Katalon team can pick up this issue, it will be very helpful."
"The product’s regression testing time could be reduced."
"We have had some issues when it comes to stability, which is something that needs to be improved."
