Offers good stability and robust but lacks generative AI capabilities

Technical support is equally very important. If you talk about anything deployed to production, and the project is live, customers are using that, and they might face some issues, some functional issues. That's when support people play a role in identifying the fix or the incident. Based on that, we create an incident based on the customer defect or whatever. Once the incident gets raised, the support will play a role in working on that particular incident. If it's a code-based incident, administration, or integration issue, support people play a big role in resolving those issues before reaching the exact developers.

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.

Cons

"It should provide more examples of script code."

"Not really sure. Maybe a .NET test runner option?"

"At various times, there are high-latency launches, or outright timeouts, but the Sauce Ops team has been pretty good about both 1) acknowledging the issue/investigation 2) working steadily to resolve it."

"When we were in development, it was a bit of a pain because we have onshore and offshore development. One of our development shops is in India, and we were running tests over there. When some of the users tried to log in, it was slow for them or we didn't have enough licenses. That was during the core development before we even launched."

"The connectivity needs improvement."

"There have been various times throughout the last month or so where the service has gone down during business hours."

"The ability to configure the memory and CPU for the test machines should be included."

"As far as what could be improved, I would say the overall test execution time."

"Mobile application testing will be an added benefit for us if LambdaTest implements this really soon."

"It would be nice to have an API for visual regression testing."

"Their smart testing module needs improvement."

"I didn't like the solution's technical support and how they communicated and tried to fix the issues of customers like me."
