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.

Scripting and basic test executions are good features; configuring the workload for tests is easy
In terms of areas of improvement, I would say the Silk Performance Explorer tool, which is used for monitoring and analysis, can be improved because that's where we spend most of our time when we're analyzing the test data. Any enhancements that can be provided in the monitoring sphere would be useful. When you have a large amount of data the tool struggles with it and will sometimes crash, or there may be issues with too many metrics being collected when running a test. The interface for the scripting could be more feature-rich. Integration with tools like Prometheus or Grafana where we can visualize the data would be great. As things stand, we have to use one monitoring tool to visualize data and another for visualizing the test metrics. Integration would enable us to see the metrics from Silk and correlate that with the metrics from other servers or other processes we're monitoring. It would save having to look at Silk data and server metrics separately. It's the way things are going with newer tools. I think the solution is being phased out by Micro Focus and their emphasis is focused more on LoadRunner. We haven't seen much development in the last few years.

Quotes from Members

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

Pros

"The product is very fast, very reliable as a solution, and well structured so you can customize it within your business workflows."
"It allows user to add whichever widget (predefined) based on the need, and it has integration with CCM and RM to achieve traceability."
"The most valuable feature is the RFT because it allows us to automate manual test cases."
"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."
"Project realization has been carried out much faster."
"Testing can be linked with requirements, which makes traceability very easy."
"The technical support has been pretty good."
"A good monitoring tool, simple to script and easy to configure."
"We haven't used Silk on any project where it hasn't been able to support whatever we have needed."
 

Cons

"Organizing the test cases is tedious. There is no mechanism to keep and maintain the test cases as hierarchy. This should be seriously addressed."
"Support of parameter needs to be easier."
"It would be helpful if we could assign a hierarchy to a group of test cases."
"I think it's fine from a performance perspective but usability is something that needs improvement."
"Adding support for uploading a collection of test cases would be a helpful addition."
"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."
"In a test plan, all of the test cases are flat and there's no hierarchy in it."
"Currently, the user interface needs to be more user-friendly."
"When you have a large amount of data the tool struggles with it and will sometimes crash, or there may be issues with too many metrics being collected when running a test."
"If you have a large amount of data, the solution can struggle."
 

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."
