Good integration with other tools, stable, scales easily

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. This includes the workbench as well as the other tools. In the future, I would like to see the other types of tests supported, that are not already covered in the DevOps approach. This would include, for example, penetration testing.

Luis Sanchez

Senior Quality Assurance Test Engineer at Dormakaba

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

"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."

"The solution scales well."

"It clearly makes it easy to test APIs based on the SOAP protocol. We are a logistics company, and we have lots of tracking calls coming in. We provide APIs for tracking services, and it makes sense for us to use SoapUI to test them thoroughly."

"One good feature is SoapUI's URL check, which allows you to check among the applications. I'm not just talking about the ones for Android. It has all kinds of multi-world tests that are really helpful."

"The utmost importance lies in the performance of the application."

"The solution offers excellent integration capabilities."

"The most valuable features are that it is user-friendly, it's easy to use and easy to teach to others."

"The tool’s scalability is very good."

"The interface is user-friendly."

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."

"SoapUI Pro is a little heavy due to the number of features. Previously it was not that heavy. Now the tool is too heavy, they should work on fixing this issue because until your system has lots of resources, you won't be able to use it seamlessly. The performance of the application itself could improve."

"There are no bugs or glitches, but a few features available only in the Pro version could be made available in the open-source version. Some of the features do not necessarily need to be only available to Pro users. The data generator would be really useful for the open-source version users."

"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."

"Automation features are not user-friendly."

"The UI should be improved."

"There aren't any plugins for UI automation. You need to make a custom code and download a job to put into the libraries. If it were panelized, then it would be straightforward. It should be in a panel of the tools, so you can add those tools as your test step in your test cases."

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

"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."

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 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."

"The cost is not that bad."

"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."

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

"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."

"ReadyAPI Test is about $680 per user, per year."
