Featured Reviews

KashifJamil - PeerSpot reviewer
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 - PeerSpot reviewer
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

"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."
"The solution offers excellent integration capabilities."
"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 tool’s scalability is very good."
"The solution has some good scanning features."
"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."
"SoapUI is uncomplicated and user-friendly."
"The utmost importance lies in the performance of the application."
"API mockups, functional testing, and load testing are valuable features."
 

Cons

"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."
"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."
"Could integrate the graphing module for load testing."
"SoapUI would benefit from some more customization abilities. It's a good interface, but it would be nice if they added the ability to build custom dashboards where the user can do their own bar graphs and pie charts."
"SoapUI Pro could improve by having dashboards."
"Grouping of the cases is not possible in SoapUI, to my knowledge. When working with critical cases or the, we were not able to group them properly. We can definitely create a suite and add them there, but within a whole suite, we have to identify them, which was not easy."
"Automation features are not user-friendly."
"The current interface is unsatisfactory."
"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."
 

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."
"ReadyAPI Test is about $680 per user, per year."
"I think the number of users is also limited, considering how much we pay."
"It is free of charge."
"The Pro version can be expensive for some companies. There are no costs in addition to the licensing fees."
"The cost is not that bad."
"ReadyAPI Test is expensive, and I rate its pricing a four out of ten."
"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."
"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."
