Manager of Central Excellence at Alpura
Easy to set up with good documentation and easy management of testing cycles
The solution allows for a complete test cycle. The management of testing cycles are easy. We have good control over test cases. We can capture functional testing very easily. We're actually able to accelerate testing now and have end-to-end cycles for testing. We didn't used to have these capabilities. It's easy to automate and accelerate testing. The product offers very good cross-browser testing capabilities. We can do continuous testing and regression testing.

Practice Specialist at a government with 1-10 employees
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.

"The major thing it has helped with is to reduce the workload on testing activities."
"The statistics that are available are very good."
"It's easy to automate and accelerate testing."
"This product offers out-of-the-box geolocation testing in automation, which is amazing!"

Cons

"I've seen a lot of potential users upset with the SilkTest due to broken installation."
"At that time, we never had good technical support in Bangalore."
"We moved to Ranorex because the solution did not easily scale, and we could not find good and short term third-party help."
"They should extend some of the functions that are a bit clunky and improve the integration."
"Everything is very manual. It's up to us to find out exactly what the issues are."
"SilkTest has to improve on Firefox and Chrome as their versions change."
"At the moment, when we are trying to use this tool, we are finding quite a few compatibility issues between the tool and the applications on the test. We wouldn't consider it perfectly stable for that reason."
"The solution has a lack of compatibility with newer technologies."
"I've also had some issues with the speed of certain API calls and the rendering of data. For example, when I'm onboarding data, the process can be slow."
"Mobile application testing will be an added benefit for us if LambdaTest implements this really soon."
"Responsive testing UI is a bit cluttered, whereas the LT browser is much better to use."
"Performing automation testing from UI is a little slow and could be improved."
"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."
"You cannot perform native-app testing, as they offer simulation for web testing only."
"I feel that the automated screenshot testing takes a little longer on MacOS sometimes."
"There is scope for improvement in service account usage, LDAP integration, and adapting new devices and features."
 

Pricing and Cost Advice
