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

"Parallel test execution helped us a lot to reduce test time."

"No need to purchase more real devices."

"Now we have more combinations that we had before and don't have to worry about scaling our script execution ourselves."

"We can now run daily and on demand automated tests."

"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."

"It runs on the cloud, so you don't have physical setups to run all of this."

"Without Sauce Labs, we wouldn't be able to test as quickly or simultaneously on various browsers."

"Testing is now easier and faster."

More Sauce Labs pros

"The Docker tunnel integration for local testing can be extremely useful to run on multiple instances in parallel."

"The UI is pretty clean and easy to navigate, and we were able to figure it out very quickly."

"It is a scalable solution."

"LambdaTest has helped me gain more customers."

"It provides 2000+ browser-OS-resolution combinations to work with, which is perfect for our consulting firm, as we don't know what our clients may need."

"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."

"The support docs are precise and you can get started with them easily."

"This product offers out-of-the-box geolocation testing in automation, which is amazing!"

More TestMu AI (Formerly LambdaTest) pros

Cons

"If I had to speak of an area that could be improved it would probably have to be the speed of interaction with the devices. There is at times a considerable amount of lag while using some of the virtual and at times even physical device farm"

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

"We have found that during automated testing this can be very slow. This causes inconsistencies with the tests."

"They should provide a JIRA integration plugin so that we can easily log issues."

"Something that needs improvement is the speed."

"I would like for there to be more detail in regards to the quality of our code i.e. how many failures occurred, how many passed based on industry standard metrics, etc."

"Sauce Labs' dashboard could be improved by adding more filters and allowing more customization options."

"For mobile testing, Sauce Labs platform is great for functional tests, but the option to run tests on real physical devices is missing right now, so it’s impossible to run performance stress tests which is also very important to test mobile apps."

More Sauce Labs cons

"LambdaTest's technical support comes in different tiers - most issues get resolved, but there's room for improvement with critical issues."

"The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers."

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

"Improvements on a platform need to happen on a timely basis...There should be some new features coming up or some performance improvisation over a period of time."

"The tool can improve its testing speed. Changing or switching to another mobile phone can be very slow on a real device."

"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."

"I would like to see all of the features available in the freemium plan so that I can test them."

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

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."

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

"Go ahead please. Try it at a smaller scale."

"It is an expensive tool."

"Trial the product and see if it suits your needs."

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