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."
"We can also submit requests multiple times and it allows us to capture the response each time by using utility scripts."
"This solution offers a free version."
"We use it for REST API testing. Feature-wise, it is pretty lightweight. It is pretty fast, and we don't have to do a lot of things. We can just simply go and post our endpoint, and it gives different kinds of authorizations. We usually use authentication 2.0, which is the most common industry practice. So, it has the support for authorization through 2.0."
"The solution is stable."
"The most valuable feature of Postman is the large libraries."
"It is easy and simple to use and install. It is compatible with Linux, Mac or Windows."
"What is most valuable for me is that we can create and share collections between the team members."
"Postman helps us to automate the API testing in the team."
"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."
"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."
"The solution can be improved by providing detailed error logs including the line the error took place to make it easier to correct."
"They should integrate the solution with one of the CRM solutions."
"Could be more user friendly."
"Should have a more improved easy-to-use interface."
"We have previously used Tosca which allowed us to verify information using authentications. It would be useful if this was also possible using Postman. In a future release, Postman should connect to DB."
"If they could implement auto-validations and assertions from SoapUI, that would be a very good feature."
