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.

Good performance testing, simple UI, and the ability to run the same script across different domains

StresStimulus simulates browser HTTP calls. I would love to see where it can also simulate a real browser to measure visually complete time. For example, to be something similar to TruClient. We run tests on SQL statements and stored procedures directly, even before integrating with UI. I wish there were a way to connect to my application DB and run SQL queries using a JDBC connection. In a world where the applications are changing every day, I hope StresStimulus comes up with an option to compare HTTP requests before and after deployment and tell me what requests have changed. This would help avoid rescripting every time, and this would be a huge deal.

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."

"All IBM testing tools are really well integrated."

"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."

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

"Designed to be a modern testing tool, StresStimulus made it easy for us to upgrade from an older deprecated testing tool and adapt to Agile DevOps testing principles by shifting left with performance testing."

"Compared to other tools, there is not a whole lot to Stress Stimulus UI. This makes it easy to use, be it while scripting, executing, or having to train someone new to the team."

"Technical support is great."

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.

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."

"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."

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

"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."

"StresStimulus has a dedicated blog where users of the tool can log new feature requests or enhancements to existing features."

"Result analysis (snap-out tabs for side-by-side comparisons) need improvement."

"Analyzing results from test runs is proving to be challenging."

"We run tests on SQL statements and stored procedures directly, even before integrating with UI. I wish there were a way to connect to my application DB and run SQL queries using a JDBC connection."

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."
