Executive SummaryUpdated on Dec 15, 2024

IBM Rational Test Workbench and LambdaTest both offer software testing solutions, with LambdaTest having the upper hand due to its cloud-based approach focused on modern testing needs.

Features: IBM Rational Test Workbench offers robust testing solutions including performance and integration testing, thorough test management, and comprehensive API testing. LambdaTest excels with real-time testing across multiple browser and OS combinations, out-of-the-box geolocation testing, and integration with CI/CD and project management tools.

Room for Improvement: IBM Rational Test Workbench could improve by enhancing its cloud capabilities, modernizing its interface, and simplifying its integration with non-IBM tools. LambdaTest can enhance its feature set by offering more in-depth reports, reducing downtime during updates, and expanding device support for mobile testing.

Ease of Deployment and Customer Service: LambdaTest's cloud-based model allows quick deployment and modern SaaS customer service, appealing to teams needing fast setup. IBM Rational Test Workbench, being on-premise-focused, requires more complex deployment, relying on traditional support models.

Pricing and ROI: IBM Rational Test Workbench involves higher initial costs due to its extensive on-premise infrastructure, potentially impacting ROI. LambdaTest offers a subscription model with competitive pricing, yielding quicker ROI through its scalable and accessible service. It provides a cost-effective alternative suitable for diverse team sizes.

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.

Technical support should be improved, though it has great documentation

We had a regression run every two weeks. During every regression testing, we had similar issues from LambdaTest's side, which was a huge problem for our tests, stability, and productivity. I had to call them every two weeks and spend two to four hours on one call to understand why this happened. The LambdaTest engineer we communicated with decided that he didn't need to fix this issue. So, I had to create a workaround from my side. This was the biggest issue I faced with the solution.

"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."

"I would like to see all of the features available in the freemium plan so that I can test them."

"You cannot perform native-app testing, as they offer simulation for web testing only."

"We get logged out of the devices if there is some inactivity."

"It would be nice to have an API for visual regression testing."

"Mobile application testing will be an added benefit for us if LambdaTest implements this really soon."

"Their smart testing module needs improvement."

"The analytics over the automation dashboard can be more intuitive."

"I feel that the automated screenshot testing takes a little longer on MacOS sometimes."
