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.
