Mohit Rathi

Lead Consultant at a tech services company with 10,001+ employees

Provides multiple test environments and saves time, but should have something for inspecting mobile apps screens

With the desktop browser, we can inspect any screen with the web developer option, but they should provide something for mobiles so that we can quickly inspect elements on the device. To write the Selenium scripts, we require web locators. We have to capture them from the local and execute the script on Sauce Labs. If Sauce Labs can provide a solution where we can inspect any of the mobile devices online, it will be very helpful for us. I also faced an issue where during the execution time, the iCloud password used to expire within a certain period, which used to create pop-ups on the screen making our tests fail. That was one thing that we faced many times. If that can be improved, it will be very helpful.

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

"Sauce Labs reduces the testing time and covers all the possible scenarios that could come up, so we don't have to worry about any scenario that we might not have missed testing manually."

"Testing subscription videos for on-demand software, making them better quality and bug free for our customers."

"Customer Service: Excellent, so far. Technical Support: Excellent, so far."

"Now I get results 100 times faster with a wider range of platforms and different browser versions used."

"The most valuable feature is the cross-browser feature, it has many android and iOS devices both simulators and real devices. It's easy to integrate. I also like video recording too."

"No need to purchase more real devices."

"Sauce Labs is a reliable vendor, and you can trust their network."

"Sauce Labs' dashboards contain multiple useful metrics in one place. Everything is represented to us visually on the dashboard, which helps us understand where to focus our attention, what the issues are, and what we need to resolve."

More Sauce Labs pros

"The primary feature that has significantly improved our test execution times is automation."

"Builds that took days to complete with in-house infrastructure were executed in a couple of hours."

"LambdaTest has made our testing process less tedious with automated parallel testing."

"It is a scalable solution."

"I was really surprised by LambdaTest; it was a very good service and for the price, I think it is a very good solution."

"Using LambdaTest, we could run all our functionality tests across various browsers, OS, and resolutions."

"LambdaTest was handy and easy enough to save us a lot of time, effort, and money."

"LambdaTest is easy to use, and the documentation provides all the needed information."

More TestMu AI (Formerly LambdaTest) pros

Cons

"I may not know what should be improved on the platform, but I think it could offer a greater variety of testing solutions. I know there might be competing solutions that cover more things I'm unaware of, and it could expand a bit more. We've done a lot of automated testing scenarios, and that's all the rage these days, so I think Sauce Labs could look at potential ways to improve and cover other scenarios."

"Sauce Labs has room for improvement with its price point. Using a real mobile device, and having that dedicated to your team, costs more than actually purchasing a mobile device. We haven't tried the real devices yet. This is because of their price point."

"I think their logging could be improved a bit, possibly to include the output that I see on my command line (print statements, etc.) which help pin-point the error (if one happens) more easily."

"Progress towards reducing application testing time can be made."

"Sauce Labs needs to be improved in the different platforms for farm testing, like iOS and Android farm testing and farm testing web browsers."

"Another feature that could still be improved on is more error clarity. Sometimes when running automated scripts the test will fail on the device side instead of the script and errors only show a 500 try again message instead of a detailed script that could of a been a timeout error from the code."

"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."

"The one issue I have is the 14-day trial that a new user gets for free."

More Sauce Labs cons

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

"The execution reporting can be improved for better integration between automation execution and accessibility platform reporting."

"Load flow compared to other stacks needs improvement."

"LambdaTest needs to have native application testing, which would be a great help to my team."

"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."

"Sometimes, when multiple users use the tool simultaneously, it can slow down, affecting efficiency."

"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."

More TestMu AI (Formerly LambdaTest) cons

Pricing and Cost Advice

"We pay for a specific number of VMs."

"We have an enterprise account; it has worked great for our needs."

"Cost-wise, it's decent. If you have to get the base version out of it, it's the best solution to go with. As compared to other cloud service providers, the pricing of Sauce Labs is decent."

"They could improve on the pricing because it seems pretty expensive. I'm sure it's justified, but it's expensive."

"The pricing is reasonable due to the amount of diversity that they provide. However, I feel they might be more flexible to bargain based on their relationship with our organization."

"We did initially go with Sauce Labs because of the pricing and integration."

"It could be less like pay-per-use with a lower rate."

"Now that we have an enterprise license, we no longer have to worry about minutes each month!"

More Sauce Labs pricing and cost advice

"The pricing for LambdaTest is affordable, and one of the reasons we implemented it."

"I used the product for free."

"LambdaTest is on the cloud, offers both free and paid plans which start at $19 USD per month."

"It is free to start, which means you can actually see how it works and then take the decision to buy."

"It is 60% cheaper and there is no fuss in maintaining the lab, so we have more time to do the testing."

"This is an affordable product."

"From the customer side, LambdaTest is cheaper for big company usage and works fine as other similar applications."

"LambdaTest is priced well, which is why we migrated to it."
