We performed a comparison between IBM Rational Test Workbench and Postman based on real PeerSpot user reviews.
Find out in this report how the two API Testing Tools solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."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."
"It's user-friendly. Anybody can learn it within five to seven minutes."
"Postman uses the DRY framework of JavaScript and that framework is easy and a good way to put assertions on responses."
"It is simple, easy to use and a good tool."
"The solution provides visibility for PDF reports without needing to install plugins."
"It is a scalable solution."
"The most valuable feature of Postman is the verification and testing of APIs."
"Postman helps us to automate the API testing in the team."
"No coding required."
"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."
"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."
"One thing which Postman needs to improve is the documentation. The documentation of Postman is not that great when compared to other tools."
"If they could implement auto-validations and assertions from SoapUI, that would be a very good feature."
"We do the implementation of Postman and give support. We had to use two engineers for the implementation, one senior and one junior for the process."
"We'd like to see some better UI in newer versions."
"It should be able to check the records and compare them to the regression testing more on the automation side."
"I was not even aware that it was possible to automate tasks in Postman...Some features related to the automation of tasks need to be added to the solution."
"If we have a certain build on one machine it won't work with another build even if we are using the same URL. It would give us a connection refuse. So developing environment compatibility would make it better."
"To get this email reporting function, we have to integrate Postman with Newman. If the two are not integrated, we won't be getting all these things in one group."
