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.

Helps in data, regression, performance, security, and functional testing

ReadyAPI Test needs to improve its reporting. While reports provide essential information when issues arise, or tests fail, having more graphical representations directly within the reports would be beneficial. It needs to improve stability and scalability as well. The tool's support is slow, and takes months to reach a solution.

Quotes from Members

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

Pros

"All IBM testing tools are really well integrated."

"Using service virtualization, we are able to accelerate the testing and development activity."

"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."

"IBM Rational integrates the testing software as Rational Test Workbench, which is quite convenient and efficient as it is able to automate the test scripts."

"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 out-of-the-box support for the database is a valuable feature."

"This product is quite useful for us."

"One of the main things that's great is the excellent integration into the DevOps tool-chain and the reuse of code between SoapUI and LoadUI."

"The solution offers excellent integration capabilities."

"Overall, I think this solution is very cool and easy-to-use."

"API mockups is a feature that quickly allowed us to have a working API mockup interface during the initial API discussion meetings."

"Using SoapUI's automation suites to run all our test cases saved us a lot of time. Running 300 test cases takes about three to four days. When you automate all that, it takes only two to three hours."

"The advantage is that the product is handy for testers, user friendly; ability to use load, security tests or create mocks."

Cons

"Implementing custom functions is bit tedious job, as ECMA script does not support some of the standard java-script functions, Also the Script editor window is not user friendly."

"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."

"Rational Performance Tester supports cloud technology in the version 8.7, playing test scripts back on the cloud is not stable."

"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.

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."

"Automation features are not user-friendly."

"It is limited to scope and risk services only. It does have some support for JMS, but it is not out-of-the-box; you have to do some tweaks here and there."

"Stability has been an issue for us. It needs to be looked at and made a bit better."

"Sometimes it would get stuck, so we had to close ReadyAPI and then start it again."

"The tools that are stated by SmartBear speaks for itself, but when it comes to improvements, there could be a release which only aims for the development of beginners in terms of understanding the tools that are laid by SmartBear."

"Could integrate the graphing module for load testing."

"Because we are paying such a huge cost, we expect more hands-on support from their research and development team."

"For automation commands, it should be able to do what SmartBear is doing with ReadyAPI."

Pricing and Cost Advice

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

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

"The cost is not that bad."

"We have team members who are working in shifts, and it is not possible for us to utilize a single license on a single piece of hardware so that multiple team members can use it. We have to take out multiple licenses for each team member."

"I think the number of users is also limited, considering how much we pay."

"It is free of charge."

"SoapUI Pro is open source but it has a subscription-based model which involves some more features. At the moment we are using the free version. The Pro version requires a license, and it is an annual license to use it."

"ReadyAPI Test is expensive, and I rate its pricing a four out of ten."

"My understanding is that the pricing is okay, however, that's taken care of by our procurement team. It's around $5,000 for three years."

"The Pro version can be expensive for some companies. There are no costs in addition to the licensing fees."
