MR
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

"Live device testing. As we all know, It's really hard and challenging to find/purchase many real devices to test because it will be costly and not all the team can be able to purchase all of the devices out there. We used to have a lot of real devices under our labs. However, it is really time-consuming to maintain those devices and make sure they are up to date with the testing requirements."
"I like the dashboard and seeing the test results. As a manager, I like to see the insights of the people using it, understanding the total path and run. I can see all of that as a manager. I also know team members love seeing the dashboard and seeing the test results in real-time."
"The combination of OS platforms, platform versions, browsers and browser versions support on VMs."
"Customer service from the initial query to sauce labs to the product evaluation to contract negotiations to purchase and installation was seamless."
"What I like most is the parallel run for multiple tests on multiple browsers simultaneously."
"Yes, it allowed us to scale mobile testing across the globe."
"Sauce Labs has been a saving grace for our company."
"With that information at hand you should be equipped to make an informed buying decision that you won’t regret."
"This product offers out-of-the-box geolocation testing in automation, which is amazing!"
"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."
"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."
"LambdaTest easily integrates with leading project management, bug tracking, and CI-CD tools like Jira, Asana, Jenkins, Circle CI, and more."
"Using LambdaTest, we could run all our functionality tests across various browsers, OS, and resolutions."
"Stability-wise, I have not experienced any downtime or other performance issues."
"HyperExecute adds significant speed to execution, enhancing the overall testing process."
"The support docs are precise and you can get started with them easily."
 

Cons

"Progress towards reducing application testing time can be made."
"I would like to see it work directly with Azure Web Apps so that we do not have to have a separate step to run tests, or setup complex flows in Jenkins."
"I would like to see improved network connectivity and it should allow playback for native apps."
"Documentation and speed."
"Sometimes the tests can pass or fail inconsistently. The tunnels and jobs timeout before the app loads, or it has to try 3 or 4 times to get a good connection."
"The slower speed needs to increase and the connectivity stability needs to improve."
"My company wanted test coverage for some devices that were not available on Sauce Labs so I still had to manage a small test lab with those devices."
"The speed needs to increase."
"The tool can improve its testing speed. Changing or switching to another mobile phone can be very slow on a real device."
"I didn't like the solution's technical support and how they communicated and tried to fix the issues of customers like me."
"Mobile application testing will be an added benefit for us if LambdaTest implements this really soon."
"LambdaTest needs to have native application testing, which would be a great help to my team."
"Load flow compared to other stacks needs improvement."
"If possible to simulate the finger pinch, it would make it more realistic."
"Mobile application testing would be helpful for us."
"For us, Cypress! It looks like the support for Cypress is not there."

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