Scalable and Stable solution with good integration function and support team
IBM Rational has the RFT, which is rational functional testing. We do test automation with rational functional testing. So after we do that, we can put in all the code, then I can build it, then put all the test cases, and put all the build code for the shared location. And then rational that shared location means that RQM has access to the shared location. So, when we execute, if a test case is automated, we can run it from RQM. We need to have the environment ready for it to execute. Once we have that, then we can select the task case. So, by clicking on one button, the other environment is automatically plugged in. Then test results will be automatically transferred back to our RQM. So, in RQM, we can view it, and it is integrated. So we can run the test and the automation from RQM, and the test results will come back. Azure DevOps first test case is there, but then we tried to use Selenium to do half automation. Still, we realized that it wouldn't have the integration. We could do something in the pipeline, but it fires the Selenium test automation code. But then the test results won't be brought back or added to AzureDesk DevOps. That's something that I do hope that there can be another other system that can have this kind of integration. RQM can be improved because it's not related to our server and could be faster. We need to find out how much database storage is needed and keep increasing it. We heard that the latest version of RQM can clean up some old ones and give the same test result. But that one feature we are yet to use. It's a setting that we can set up, and then it goes automatically or gives me the choice to do it manually.

One area where k6 could improve is by introducing a GUI similar to JMeter. While k6 is a powerful tool for performance testing, it leans heavily towards coding. Having a GUI, even if it is a low-code approach, could make it more accessible to a broader audience. It would be beneficial to strike a balance where basic tasks can be performed graphically through a user-friendly interface, while still allowing the flexibility for more complex operations through code, similar to how JMeter operates. This could enhance the user experience and make k6 more approachable for those who may not be as comfortable with scripting.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"RQM's best features are integration with test automation and performance testing."
"The technical support has been pretty good."
"Reusability and integration capabilities which make it a great choice for organizations that use a variety of development tools and platforms."
"In the latest version, Global Configuration is the most promising feature as it allows the user to maintain different versions of the same artifact in different streams."
"It allows user to add whichever widget (predefined) based on the need, and it has integration with CCM and RM to achieve traceability."
"Testing can be linked with requirements, which makes traceability very easy."
"Integration with the other professional tools is a very strong advantage, so that we can have a traceability between the requirements and defects in Rational Team Concert. That's the most important aspect."
"The technical support from IBM is very good."
"The tool's big advantage is that it is more performance-test oriented for experienced testers who know what they are doing. In a normal working setup, performance engineers frequently work with DevOps and development teams. For these teams, k6 Open Source's syntax is much simpler and easier to understand and apply in the working process."
"The standout feature of k6 is its strong focus on API performance testing."
 

Cons

"Adding support for uploading a collection of test cases would be a helpful addition."
"Currently, the user interface needs to be more user-friendly."
"For the CLM tools, IBM provides a good automatic setup, but on the WebSphere side, there is a lot of complex configuration to attend the services."
"The user interface can be improved; it is the same interface that I have been seeing for the past so many years, whereas the other CLM modules changed significantly."
"It would be helpful if we could assign a hierarchy to a group of test cases."
"Mainly Quality Assurance and DevOps, but of course the whole company and management areas with more knowledge of quality and client success approach."
"Organizing the test cases is tedious. There is no mechanism to keep and maintain the test cases as hierarchy. This should be seriously addressed."
"I think it's fine from a performance perspective but usability is something that needs improvement."
"One area where k6 could improve is by introducing a GUI similar to JMeter."
 

Pricing and Cost Advice

"The licenses of these tools (the whole CLM package) is very costly as compared to other vendors' tools."
"Each license includes 12 months of customer support. A free 90-day trial of the software is also available."
