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

"Testing is very fast with this tool."

"The most valuable feature is the ability to easily test multiple browsers and versions, as well as off-loading our local environments using the SauceCloud."

"It has a wide assortment of platforms."

"Customer Service: Excellent, so far. Technical Support: Excellent, so far."

"Overall, Sauce Labs has provided us with a VM farm that is virtually always up and running and has taken the burden off of us/myself of maintaining the VM farm."

"I've been able to help numerous companies get up and running with Selenium quickly thanks to Sauce Labs."

"I think its excellent and everyone should get it – I recommend it to everyone."

"I love the capabilities of it, the support, and the service."

More Sauce Labs pros

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

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

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

"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."

"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’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."

"LambdaTest has helped me gain more customers."

"The solution is very easy to understand and has a user-friendly UI."

More TestMu AI (Formerly LambdaTest) pros

Cons

"Overall, I think Sauce Labs provides us with a valuable tool and resource. As far as what could be improved, I would say the overall test execution time. Some of the calls take a bit longer than I expect, for example in web browser tests; while the execution time isn't obnoxious, it could be improved so that overall tests/test suites finish faster."

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

"Sauce Labs has room for improvement with its price point. Using a real mobile device, and having that dedicated to your team, costs more than actually purchasing a mobile device. We haven't tried the real devices yet. This is because of their price point."

"The only problem is that hit that point where it’s unfeasible to expand our UI testing framework as the cost to run a shed load of tests is too much for our business."

"Latency, due to Sauce Labs being a cloud-based solution, has been a concern. We work in different continents and countries, but last time I checked, Sauce Labs was only offering two data centers, one in the EU and another in the US. If you're not in either of those two places, you would have latency and issues running your test cases."

"The testing process is difficult. I need to prove the complete competency of the tool, and I am finding that challenging."

"The Jenkins Sauce OnDemand plugin could have more options available to tap into more of the custom capabilities Sauce Labs actually supports."

"They could improve the platform's customer support services."

More Sauce Labs cons

"It would be nice to have an API for visual regression testing."

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

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

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

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

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

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

"For us, Cypress! It looks like the support for Cypress is not there."

More TestMu AI (Formerly LambdaTest) cons

Pricing and Cost Advice

"The pricing is reasonable due to the amount of diversity that they provide. However, I feel they might be more flexible to bargain based on their relationship with our organization."

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

"We did initially go with Sauce Labs because of the pricing and integration."

"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!"

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

"It is an expensive tool."

"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"."

More Sauce Labs pricing and cost advice

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

"I used the product for free."

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

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

"This is an affordable product."

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

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

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