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 helps me to test APIs independently. It also supports hosting."
"It is stable and does not lag."
"What is most valuable for me is that we can create and share collections between the team members."
"The solution collects scenarios and allows for testing SOAP API, REST API and API automation at the same time."
"It is stable and reliable."
"The initial setup of this solution is straightforward. Postman can be used as an extension in Google Chrome for those who do not wish to install it directly. Deployment took an hour and a half."
"Postman allows you to incorporate and export the test cases we create. It enables me to share the test cases with my colleagues, so I don't have to copy them into an Excel sheet. Postman lets me export the dataset and share it with my team. They can use my test case for their testing."
"Good at simulating the API code from a fictitious client application to check API behavior."
"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."
"We'd like to see some better UI in newer versions."
"I would like to see advanced automation in reference to Postman."
"The performance needs to be improved."
"They should provide more specific documentation on configuration."
"The reporting could be better. It should give you a detailed PDF report after you run a test."
"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."
"One area that could be better is collection management."
"I live in Turkey, so for me, the value of dollar currency is high...Postman can change its pricing policy and decrease the prices for Turkey."
