Very good performance and load testing capabilities
There are some compatibility issues with the load standpoint test. When we use the solution instead of Microsoft Edge, more scripting is required. The reports for structure point or test management could be more compatible with other tools. For example, when I create an application I sometimes cannot generate a report.

Cloud-based testing has simplified remote mobile validation and provides flexible device coverage
I was not impressed with how detailed their analytics and logs are from LambdaTest. The solution we were testing is being used because many of us are working from home. It was easy to implement because with a real phone, we have to bring a real phone to each person. Since three years ago, many employees have been working from home, so we were trying to find a solution for this challenge. We had no need to exploit the information for the analytics generated in the background. The purpose was simply to make it easy for our employees to access a phone. The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers. The contrast on a real iPhone provides better contrast than with the cloud solution. The only aspect that was less favorable than on a real phone was the contrast of the color.

Quotes from Members

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

Pros

"Has a very smooth process for launching and closing the application after execution."
"The way it identifies elements is good."
"The most valuable aspects of the solution are the font, size, and interface."
"The object repository is the most valuable feature, as different elements can be identified and reutilized through the repository across other scripts, and the product has a very smooth process for launching and closing the application after execution."
"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."
"The performance and load testing are very good."
"I am really glad that there are tools like LambdaTest that help freelancers like me to make sure everything is okay before finally making a website live."
"Geolocation testing is as straightforward as ticking checkboxes of browsers, operating systems, and countries."
"The UI is pretty clean and easy to navigate, and we were able to figure it out very quickly."
"LambdaTest is brilliant."
"The real devices feature is the most valuable feature for us."
"Automation and mobile testing have improved our efficiency."
"LambdaTest has made our testing process less tedious with automated parallel testing."
"LambdaTest Selenium Grid has helped us radically reduce the manual testing effort and ensure browser compatibility."
 

Cons

"The first time I customized the solution, it was quite challenging."
"We have not seen a return on investment yet."
"It can be improved by including a feature that allows multiple file types to be selected simultaneously."
"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."
"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."
"Sometimes, when multiple users use the tool simultaneously, it can slow down, affecting efficiency."
"Responsive testing UI is a bit cluttered, whereas the LT browser is much better to use."
"The scalability is good with Amazon, but IBM had some issues."
"LambdaTest's technical support comes in different tiers - most issues get resolved, but there's room for improvement with critical issues."
"It would be nice to have an API for visual regression testing."
"Analytics could be better because as of now, it gives basic information on test status and build status."
"You cannot perform native-app testing, as they offer simulation for web testing only."
"The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers."
