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

"The ROI is 100%."

"The solution they provide is very robust. We can quickly connect to their environment with the hub URL. They have a URL that has the entire grid of desktops, web browsers, and mobile devices. They also provide real devices, so you just provide the URL and test your application."

"This product is a big time-saver, so by extension, it's a cost-savings."

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

"The error logging is also very robust. If we run a test through Sauce Labs and there's some sort of issue, a log will appear on the screen. Log messages are usually heinous and horrible... Sauce Labs is incredibly good at saying things like, 'Hey, here is the exact issue. Fix this and you can run the test.' That helps in getting things up and running and executing the way they should."

"Cross-platform mobile testing. Before using Sauce Labs, I would have to setup a Selenium Grid cluster and install all versions of mobile simulators/emulators in order to test apps on different platforms."

"The temporary storage they are giving is just awesome."

"Reliable access to VMs with built-in recording and log tools have improved release reliability and confidence."

More Sauce Labs pros

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

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

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

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

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

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

"With LambdaTest, we could see improvements in identifying errors before our customer does."

"Automation and mobile testing have improved our efficiency."

More TestMu AI (Formerly LambdaTest) pros

Cons

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

"Better and programmatic controls on request/response recordings and sharing with developers."

"Playback needs improvement."

"Multi-domain SSO is a big concern for us right now, especially as we've been merged into a larger company. I suddenly have teams coming from 20 different domains, and because the main master Sauce Labs account is locked down to one SSO domain, there are teams that can't run a test right now. I've heard they're working on a solution and they've been very communicative with us about it. A solution to that would help us a lot."

"We still see simulators for a few mobiles in their VM's, we want to test on real devices."

"The session duration is too short; it's only about 3 hours long."

"The ability to install profiles on iOS real mobile devices should be included."

"Speeds up the time it takes to run end-to-end user interface (UI) tests inside their virtual machines (VMs)."

More Sauce Labs cons

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

"Performing automation testing from UI is a little slow and could be improved."

"Analytics could be better because as of now, it gives basic information on test status and build status."

"Mobile application testing would be helpful for us."

"I feel that the automated screenshot testing takes a little longer on MacOS sometimes."

"LambdaTest needs to improve its speed and memory because it takes a long time to load."

"The analytics over the automation dashboard can be more intuitive."

"Their smart testing module needs improvement."

More TestMu AI (Formerly LambdaTest) cons

Pricing and Cost Advice

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

"When you reach the Enterprise licensing tier, base level being with 10 concurrent test sessions, pricing is essentially per-unit-of-concurrency thereafter with a relatively linear increase and not much benefit for "bulk"."

"The pricing is definitely on the higher end, and there are other options that are more cost-effective."

"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."

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

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

"Their pricing is incredibly competitive."

"We pay for a specific number of VMs."

More Sauce Labs pricing and cost advice

"This is an affordable product."

"LambdaTest is paid per execution."

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

"It is affordable as compared to similar SaaS solutions."

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

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

"The pricing could be made cheaper."

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