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

"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."
"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 Pro and free version of SoapUI Pro has good technical support."
"The solution offers excellent integration capabilities."
"The tool’s scalability is very good."
"It's a very simple solution to use."
"The most valuable features are that it is user-friendly, it's easy to use and easy to teach to others."
"SoapUI Pro is a good tool when it comes to API design and orchestration. Additionally, it is beneficial for functional and for performance testing."
"ReadyAPI has the power to enrich all the technical work. You can achieve any complex task using ReadyAPI. I can also do UI automation with ReadyAPI. In a few test cases, we want to check the API and the equivalent UI. I download a job and write a piece of Groovy or Java code. It's almost the same in ReadyAPI. I can do that in a single test case. ReadyAPI is a powerful tool because you can do anything you want, but only you need to download the right set of jobs and produce the right set of code."
 

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."
"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."
"I would like more documentation, training, tutorials, etc. Also, I don't particularly appreciate that I have to save everything. It takes up a lot of space on my laptop, but I have to install the WSDL again If I don't save it."
"The documentation needs to be improved because the interface is not easy for a first-time user."
"Stability has been an issue for us. It needs to be looked at and made a bit better."
"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."
"If the load and bare minimum could be defined, I would give this solution a higher rating."
"The current interface is unsatisfactory."
 

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."
"It is free of charge."
"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."
"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."
"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."
"ReadyAPI Test is about $680 per user, per year."
