Executive SummaryUpdated on Dec 15, 2024

IBM Rational Test Workbench and Telerik Test Studio are competing products in the automated testing space. IBM shows strength in integration with its ecosystem, while Telerik leads with ease of use and quick setup.

Features: IBM Rational Test Workbench supports extensive test management, service virtualization, and robust integration with IBM tools. It is suitable for complex test environments and offers powerful API, performance, and service virtualization testing. Telerik Test Studio offers an intuitive interface with powerful automation, including features like PDF validation, an object repository for element reuse, and an efficient record and playback feature.

Room for Improvement: IBM Rational Test Workbench could benefit from a smoother deployment process, less complexity in initial setup, and more direct support for agile methodologies. Telerik Test Studio may improve by expanding its integration options, enhancing reporting functionality, and offering more advanced test management features for large-scale environments.

Ease of Deployment and Customer Service: Telerik Test Studio is known for its straightforward deployment suited to agile workflows and responsive customer support. IBM Rational Test Workbench offers comprehensive support but tends to require more time for integration due to complexity, making it more appealing for firms already using IBM solutions.

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.

Supports multiple platforms and identifies elements in a good way

Instead of Telerik Test Studio, I'd recommend writing test cases in .Net so that in the future, if you move away from Telerik Test Studio to another tool, it would be easier for you. Your current code would be reusable. You won't have to change your test cases much. We wrote our code in a separate IDE, which was Visual Studio, and internally, we had the infrastructure to interact with Telerik Test Studio. All the internal logic that we needed for our purpose was implemented in .NET, and we used Telerik Test Studio for tests. I'd rate Telerik Test Studio an eight out of ten.

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."

"The most valuable aspects of the solution are the font, size, and interface."

"Has a very smooth process for launching and closing the application after execution."

"The performance and load testing are very good."

"The way it identifies elements is good."

"Before using Telerik Test Studio, I was a manual tester, so it was my first automation tool, yet I felt very comfortable using it. I've used the record and play feature, and Telerik Test Studio was easy to use. The tool was easy to understand, even for a first-time user like me."

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."

"It can be improved by including a feature that allows multiple file types to be selected simultaneously."

"The charts need to be more detailed and customizable."

"I observed that the Excel and Word validation was quite challenging, which is an area for improvement in the tool. I also experienced minor difficulties with Telerik Test Studio, particularly in fetching elements in some scenarios when using C# for coding."

"There are some compatibility issues with the load standpoint test."

"Its UI is not very user-friendly and could be improved. For new users, it isn't easy."

Pricing and Cost Advice

"The pricing is a little bit on the higher side, although it is really good."

"It doesn't really concern me. Licensing is on a yearly basis."

"The pricing is fair so I rate it an eight out of ten."
