IT Specialist, ITE at a government with 10,001+ employees

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.

Quality Specialist 2A at a financial services firm with 10,001+ employees

Has reduced manual testing effort with customization options but occasionally crashes during complex executions

One improvement would be to integrate it with modern technologies such as AI, so we can generate test cases by providing the details so that it can generate the structure, and later the person working can modify and enhance it. We can add more customized tools, and reporting can be enhanced. Currently, the reporting part is at a step level, and it does not give details for a particular test case, so improvements in those areas would be beneficial. There are performance issues where the tool crashes sometimes. In particular use cases with numerous steps, it experiences crashes. I have encountered stability and performance issues with it.

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."

"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."

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

"One key feature of using SOAtest tool is that it provided us early entry in testing cycle without any services."

"One of the most valuable features I found in Parasoft SOAtest is its ability to extend the product."

"It improved my project ROI in various portions of the testing life cycle."

"We do a lot of web services testing and REST services testing. That is the focus of this product."

"This tooling made us more agile and more ready for continuous integration."

"SOATest provided a platform for automated testing and creating an enriched automated regression suite."

"We can automate our scenarios in a data driven format, which shows there is no rework on scripts. We only need to update the test data and run for a number of scenarios."

"SOAtest is, at its base, a collection of tools that can be combined to generate test scenarios, where input data can be gathered from any possible source from web GUIs, databases, Excel, and files and is used in SOAP/REST tools and web browser tools, and the output of those tests can be saved in files and databases, so every imaginable source in the entire world of information technology can be accessed and used."

"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."

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

"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."

"I personally feel that 50% of Parasoft features are provided by SoapUI free of cost."

"Performance issues if there are too many sessions open on your system."

"The feedback that we received from the DevOps of our organization was that the tool was a little heavy from the transformation perspective."

"There are performance issues where the tool crashes sometimes. In particular use cases with numerous steps, it experiences crashes."

"One area that could use improvement is the cryptography capabilities in Parasoft SOAtest. It did not support enough of the protocols or cryptography formats we needed, which led us to create our own solutions."

"We noticed that our project workspace is sometimes corrupted without any reason."

"More descriptive reports are needed."

"The features of SOAtest used for testing (web) applications on user interface level suffice for very basic web applications, but there are better tools on the market."
