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

"I cannot imagine our company without Sauce Labs."

"What I like the most is the cloud running the automation test with the help of a number of devices."

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

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

"Having the ability to test our application on additional browser/OS/mobile device combinations opens up additional revenue streams for us because we have a larger user base."

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

"Has freed up huge amounts of time managing integrations."

"It provides a comprehensive selection of browsers and platform versions for our test automations and CI/CD pipeline process. It also provides a comprehensive set of virtual mobile devices, which we can configure for our automation and availability. These features are valuable for us when it comes to testing our applications. We have a website and mobile applications that we want to test and diversify to various browsers and mobile devices as well as restore various versions. This helps us to find bugs that users might be facing and correct them."

More Sauce Labs pros

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

"Our test execution time was reduced to 16 mins from five hours when executed in parallel on multiple VMs. This has been extremely helpful!"

"It is a scalable solution."

"LambdaTest is brilliant."

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

"It's user-friendly and offers valuable features for testing, making it a reliable tool."

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

"Automation and mobile testing have improved our efficiency."

More TestMu AI (Formerly LambdaTest) pros

Cons

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

"The real concern is the load time of applications or real devices when we start our tests. It takes some time to load the application or web browser. Sometimes, it is frustrating too. Since they are real devices, we understand it takes some time to load. However, if it were to improve, then that would be a great asset to the solution. So, we would like better responsive times when opening applications and running tests."

"I only tried the free trial so far, so not a lot to say about the cons."

"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."

"It would be very good to see a short example of the code that needs to pass into Driver capabilities, something like auto-generation of this block."

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

"Yes, the parallelization is not possible now when cucumber and junit are used together."

"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."

More Sauce Labs cons

"Mobile application testing would be helpful for us."

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

"If possible to simulate the finger pinch, it would make it more realistic."

"You cannot perform native-app testing, as they offer simulation for web testing only."

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

"There is scope for improvement in service account usage, LDAP integration, and adapting new devices and features."

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

"We get logged out of the devices if there is some inactivity."

More TestMu AI (Formerly LambdaTest) cons

Pricing and Cost Advice

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

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

"We pay for a specific number of VMs."

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

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

"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"."

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

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

More Sauce Labs pricing and cost advice

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

"I used the product for free."

"LambdaTest is paid per execution."

"This is an affordable product."

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

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

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

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