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

"With Sauce Labs, we have a whole universe of devices: Galaxy, all the iPhones, and all the operating system versions. All our software developers are able to test on a multitude of different devices."

"Running tests in parallel."

"Of all the services explored, Sauce Labs offers the single best solution for integrating deep automated browser testing in a CI/CD pipeline, and integrates best with Jenkins."

"Yes, it allowed us to scale mobile testing across the globe."

"A cross browser test platform is really important for a web designer, Sauce Lab providing a really fast, functional and with good quality service."

"The best feature though is the fact that they use the WebDriver protocol for executing actions on their service."

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

"Allows us to do JIRA Cloud and BambooHR Integration."

More Sauce Labs pros

"LambdaTest is a saving soldier for our company by offering us thousands of browsers and platforms to test on the cloud."

"Stability-wise, I have not experienced any downtime or other performance issues."

"LambdaTest supports multiple platforms like iOS across different devices and enables real-time testing."

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

"In case something goes wrong at LambdaTest end, the Support team is extremely responsive to analyze any platform-related issues."

"LambdaTest proved to be a savior for us here, as one platform does the job!"

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

"It’s good to see, now that we are using LambdaTest, we can run multiple tests on multiple VMs, saving us hours of testing time and the maintenance cost of local infrastructure."

More TestMu AI (Formerly LambdaTest) pros

Cons

"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."

"Some of the new features could be improved, for example, the playback on simulators."

"They still have very slow support and ask many excessive questions before starting to fix the issue."

"Sometimes, it is not stable."

"We encountered minor issues with stability from time to time but Sauce Labs continues to make improvements."

"Sauce Labs has room for improvement with its price point."

"An image comparison would be a nice feature to include in the Sauce Labs product."

"As a web product QA team, we sometimes need to spot check some new child site on multiple browsers and OS(es). It was a little time consuming for us since we need to click on each of the browser/OS combinations and start a new session to test. Every sprint, with new features and child pages being added, we mostly need to do the same steps over and over again."

More Sauce Labs cons

"The scalability is good with Amazon, but IBM had some issues."

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

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

"It would be much easier for us to read the test if they provided dashboard analytics."

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

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

"I've also had some issues with the speed of certain API calls and the rendering of data. For example, when I'm onboarding data, the process can be slow."

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

More TestMu AI (Formerly LambdaTest) cons

Pricing and Cost Advice

"We pay for a specific number of VMs."

"Try the free trial and work with a Sauce Labs representative to see what package works best for your application(s)."

"Their pricing is incredibly competitive."

"The number of concurrent VMs that Sauce Labs provides depends on your purchase license level."

"With respect to pricing, they did a bundled discount because we went with Sauce Labs for both mobile and browser. They were very competitive on pricing and provided a bundle discount for us as a larger customer."

"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."

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

More Sauce Labs pricing and cost advice

"LambdaTest's pricing is cheaper than that of other similar platforms."

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

"The tool is not cheap, but it is not expensive."

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

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

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

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

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