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.

Reliable and easy to expand with a helpful API network

There is a product called Guidewire that sends the data in an XML format. It's like a policy load. That information we trigger in Kafka. Kafka will take the information and send it to the REST API. With Kafka, they wanted to make two APIs to consolidate the effort. At that time, we are using the POST API tool. This tool is helping us to synchronize everything.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."

"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."

"Postman helps to write pre-request scripts and make a collection out of each request. You don’t have to spend time writing or copying the requests. The solution lets you integrate multiple environments and their features. Either the tool’s pro or premium version lets you do the merge and pull request for the Git directly."

"It is stable and does not lag."

"The most valuable feature of Postman is the verification and testing of APIs."

"Postman is easy to use and enables us to test all possible API testing scenarios."

"Postman is very user-friendly and accessible even for those with minimal experience."

"The solution collects scenarios and allows for testing SOAP API, REST API and API automation at the same time."

"Postman helps us to automate the API testing in the team."

"The API testing features are valuable."

Cons

"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."

"Postman does not have database validation available, which affects its scalability."

"One of the features that is missing in Postman is reporting; it's very basic."

"I would like to see more integrations with other platforms."

"Multi-part requests should be handled in the octet-stream."

"I rate the support for Postman a four out of five."

"There is no support for the testing of the SOAP APIs."

"Integration of the solution towards Bitbucket, BitHub, and CI pipelines is difficult."

"Testing API is pretty straightforward in Postman, but it falls short when testing web services. For example, when we test web services, there is a visual component that we can import in SoapUI but not in Postman."

Pricing and Cost Advice

"The pricing is a little bit on the higher side, although it is really good."

"It doesn't really concern me. Licensing is on a yearly basis."

"I rate the product's price a nine or ten on a scale of one to ten, where one is cheap, and ten is very expensive. Postman is an expensive tool for Turkey."

"Unlike APIs, the solution does not require a license."

"I am using the free option."

"It is free."

"This tool is open-source and free to download and use."

"Its price is moderate as compared to other competitors. The version that we are using is not open source, so it is not free."

"The solution is free for individuals, but for companies that use it across the organization, you have to pay per user."

"This solution offers a free version."
