KashifJamil - PeerSpot reviewer
Good integration with other tools, stable, scales easily
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. This includes the workbench as well as the other tools. In the future, I would like to see the other types of tests supported, that are not already covered in the DevOps approach. This would include, for example, penetration testing.
Dinesh Saharan - PeerSpot reviewer
The tool reduces the manual effort needed and helps automate certain tasks for users
I won't be able to comment on what could be improved in the solution since I am not the one who handles LambdaTest. It is our company's IT team that takes care of LambdaTest. Improvements on a platform need to happen on a timely basis. If something is perfect, it doesn't mean that it doesn't need to improvise or improve, like in terms of adding new features. There should be some new features coming up or some performance improvisation over a period of time.

Quotes from Members

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

Pros

"This solution provides for API testing, functional UI testing, performance testing, and service virtualization."
"Reporting is pretty good. Its interface is also good. I'm overall pretty happy with the functionality and use of IBM Rational Test Workbench."
"It is a scalable solution."
"The technical support services are excellent."
"The Docker tunnel integration for local testing can be extremely useful to run on multiple instances in parallel."
"HyperExecute adds significant speed to execution, enhancing the overall testing process."
"The most valuable feature is the real-time testing, which helps you to test your website on more than two thousand combinations of browsers and operating systems."
"Without a doubt, LambdaTest is one of the big reasons behind our faster deployment and better team collaboration."
"This product offers out-of-the-box geolocation testing in automation, which is amazing!"
"The slow nature of a cloud platform was compensated with parallel testing, and now we are able to finish our testing job faster than it was before COVID."
 

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. 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."
"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."
"The scalability is good with Amazon, but IBM had some issues."
"I think Lambdatest is a valuable tool for our team and things that have room for improvement would be mobile app testing, as it can be an important addition to the tool."
"Mobile application testing would be helpful for us."
"The analytics over the automation dashboard can be more intuitive."
"It would be nice to have an API for visual regression testing."
"The tool can improve its testing speed. Changing or switching to another mobile phone can be very slow on a real device."
"Performing automation testing from UI is a little slow and could be improved."
"LambdaTest needs to have native application testing, which would be a great help to my team."
 

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."
"This is an affordable product."
"The tool is not cheap, but it is not expensive."
"I used the product for free."
"It is free to start, which means you can actually see how it works and then take the decision to buy."
"LambdaTest's pricing is cheaper than that of other similar platforms."
"The pricing for LambdaTest is affordable, and one of the reasons we implemented it."
"LambdaTest is priced well, which is why we migrated to it."
"LambdaTest is on the cloud, offers both free and paid plans which start at $19 USD per month."
