JG
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.

Quotes from Members

Pros

"The statistics that are available are very good."
"The scalability of the solution is quite good. You can easily expand the product if you need to."
"The Silk4J feature is the solution's most valuable aspect."
"The solution is user-friendly with respect to automation."
"Scripting is the most valuable. We are able to record and then go in and modify the script that it creates. It has a lot of generative scripts."
"It's easy to automate and accelerate testing."
"It speeds up testing efforts."
"It is a fine product; it is a powerful tool, and it needs commitment."
"Builds that took days to complete with in-house infrastructure were executed in a couple of hours."
"This product offers out-of-the-box geolocation testing in automation, which is amazing!"
"It is a scalable solution."
"Stability-wise, I have not experienced any downtime or other performance issues."
"Geolocation testing is as straightforward as ticking checkboxes of browsers, operating systems, and countries."
"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."
"The primary feature that has significantly improved our test execution times is automation."
"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

"Implementing a better integration with Git. It was extremely painful to implement the link from Silk Central to Git."
"The support for automation with iOS applications can be better."
"The initial setup is somewhat complex if you're deploying on-prem."
"The pricing is an issue, the program is very expensive. That is something that can improve."
"SilkTest has to improve on Firefox and Chrome as their versions change."
"The browser based testing needs to be improved."
"The solution has a lack of compatibility with newer technologies."
"Could be more user-friendly on the installation and configuration side."
"You cannot perform native-app testing, as they offer simulation for web testing only."
"I didn't like the solution's technical support and how they communicated and tried to fix the issues of customers like me."
"If possible to simulate the finger pinch, it would make it more realistic."
"Mobile application testing will be an added benefit for us if LambdaTest implements this really soon."

"The product can be described as an averagely-priced solution."
