Provides real-time application monitoring, but the technical support services need improvement
They could improve the platform's customer support services. Many users, including myself, have experienced significant delays in response times and unsatisfactory resolutions when reaching out for assistance. The support team often provides generic recommendations that do not address the specific issues raised, leading to prolonged downtime. Additionally, there needs to be more proactive communication and follow-up on reported problems. Another area for improvement is keeping pace with updates to the latest libraries and technologies. For example, Sauce Labs' proprietary driver and Saucectl need to be updated more frequently to support the latest versions of popular testing frameworks like Playwright. This lag in compatibility means that users may miss out on critical features and improvements available in newer versions, necessitating workarounds or compromises in their testing workflows.

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

"It has a wide assortment of platforms."
"The Failure Analysis feature is really important for us, one of the most important aspects. What is the root cause? Is it because we have a defect or is it that we have a test case that we need to fix or modify? The Failure Analysis is one of the main functionalities that I am exploring all the time in Sauce Labs... The Failure Analysis helps us to discover which test cases we need to work on."
"As stated earlier we use Sauce Labs for a combination of automated testing and manual testing. Therefore the most useful features are the ability to run the functional automated tests via a Sauce Labs tunnels which allows access to applications in our internal network. The second most useful feature is the manual side."
"The most valuable feature is the ability to run concurrent automated tests up to a specified value, depending on what we are currently paying for."
"They update for the latest browsers and mobile phones and support a lot of combinations. They have 1,000-plus desktop combinations and browser versions, which is really great. We need that at Applause. The all-in-one testing suite aspect of it is really important because most of our clients prefer to go to one place."
"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."
"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."
"Supplying devices to a testing team of possibly close to one thousand testers and developers is a great undertaking but Sauce Labs has made this very easy and a welcomed solution."
"It's user-friendly and offers valuable features for testing, making it a reliable tool."
"I was really surprised by LambdaTest; it was a very good service and for the price, I think it is a very good solution."
"LambdaTest supports multiple platforms like iOS across different devices and enables real-time testing."
"The primary feature that has significantly improved our test execution times is automation."
"The most valuable feature is the real-time testing, which helps you to test your website on more than two thousand combinations of browsers and operating systems."
"The technical support services are excellent."
"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."
"LambdaTest easily integrates with leading project management, bug tracking, and CI-CD tools like Jira, Asana, Jenkins, Circle CI, and more."
 

Cons

"They should provide a JIRA integration plugin so that we can easily log issues."
"Lacks the ability to start multiple tests simultaneously."
"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."
"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."
"I would like to see improved network connectivity and it should allow playback for native apps."
"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."
"We have found that during automated testing this can be very slow. This causes inconsistencies with the tests. It's very difficult to rely on a service when you can't be sure if a test will pass or fail the next time it runs. This means building in a lot of sync time into the tests which in turn slows them down. If this speed could be improved then the service would be much better."
"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 tool can improve its testing speed. Changing or switching to another mobile phone can be very slow on a real device."
"Improvements on a platform need to happen on a timely basis...There should be some new features coming up or some performance improvisation over a period of time."
"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."
"I would like to see all of the features available in the freemium plan so that I can test them."
"The scalability is good with Amazon, but IBM had some issues."
"We get logged out of the devices if there is some inactivity."
"You cannot perform native-app testing, as they offer simulation for web testing only."
"I feel that the automated screenshot testing takes a little longer on MacOS sometimes."
 

Pricing and Cost Advice

"Trial the product and see if it suits your needs."
"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."
"The number of concurrent VMs that Sauce Labs provides depends on your purchase license level."
"Go ahead please. Try it at a smaller scale."
"The pricing is definitely on the higher end, and there are other options that are more cost-effective."
"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."
"​Now that we have an enterprise license, we no longer have to worry about minutes each month!​"
"Their pricing is incredibly competitive."
"LambdaTest is paid per execution."
"LambdaTest is on the cloud, offers both free and paid plans which start at $19 USD per month."
"It is 60% cheaper and there is no fuss in maintaining the lab, so we have more time to do the testing."
"LambdaTest's pricing is cheaper than that of other similar platforms."
"LambdaTest is priced well, which is why we migrated to it."
"The tool is not cheap, but it is not expensive."
"I used the product for free."
"It is affordable as compared to similar SaaS solutions."
