AS
QA engineer at Siznam and Co
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

"Testing my app on cloud has really helped us with save time and resources to procure various hardware and software, and set those up."
"With Sauce Labs, we are able to cover multiple Chrome, Firefox, and Safari variations to support and test for all users."
"The insights section provides a great overall state of the automation suite and can identify trends relatively quickly."
"I have found the live test section with Sauce Labs to be extremely valuable. When you can't quite figure out why a test is failing, you can go to the live test results section within their tool and launch your test (specifying a given OS/browser, or device) manually and step through the test to see the issue more clearly, usually opening up the developer's tool console and watching the network calls and console (within Chrome) to usually find the underlying issue."
"Sauce Labs is one of the smoothest products we've integrated with and currently use."
"Our machines are mostly Windows. Being able to test with Safari, on a Mac, and other types of browser pieces without having to manage all the infrastructure is the biggest feature that our team enjoys."
"Sauce Labs is optimized for automation and integration with the major CI/CD platforms and developer tools. We have an integration with App Center that we're working on. They have a storage API that lets us retrieve APK and IPA, iOS and Android builds off the phone, so that we can continue testing with CI/CD. They integrate with Jenkins, and Jenkins is the main CI/CD."
"Sauce Lab analytics helped us to get detailed knowledge on test cases execution and logs."
"The Docker tunnel integration for local testing can be extremely useful to run on multiple instances in parallel."
"HyperExecute adds significant speed to execution, enhancing the overall testing process."
"This product offers out-of-the-box geolocation testing in automation, which is amazing!"
"LambdaTest easily integrates with leading project management, bug tracking, and CI-CD tools like Jira, Asana, Jenkins, Circle CI, and more."
"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."
"LambdaTest is easy to use, and the documentation provides all the needed information."
"LambdaTest proved to be a savior for us here, as one platform does the job!"
 

Cons

"The ability to install profiles on iOS real mobile devices should be included."
"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."
"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."
"Better and programmatic controls on request/response recordings and sharing with developers."
"Speeds up the time it takes to run end-to-end user interface (UI) tests inside their virtual machines (VMs)."
"We have found that during automated testing this can be very slow. This causes inconsistencies with the tests."
"User account management needs an overhauls, allowing for user groups rather than just a hierarchy structure."
"They could improve the platform's customer support services."
"It would be much easier for us to read the test if they provided dashboard analytics."
"I feel that the automated screenshot testing takes a little longer on MacOS sometimes."
"I feel that the automated screenshot testing takes a little longer on MacOS sometimes."
"For us, Cypress! It looks like the support for Cypress is not there."
"Analytics could be better because as of now, it gives basic information on test status and build status."
"If possible to simulate the finger pinch, it would make it more realistic."
"The scalability is good with Amazon, but IBM had some issues."
"Responsive testing UI is a bit cluttered, whereas the LT browser is much better to use."
 

Pricing and Cost Advice

"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."
"Their pricing is incredibly competitive."
"The number of concurrent VMs that Sauce Labs provides depends on your purchase license level."
"It is an expensive tool."
"Go ahead please. Try it at a smaller scale."
"​Now that we have an enterprise license, we no longer have to worry about minutes each month!​"
"Compared with other services, Sauce Labs is a bit 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"."
"It is 60% cheaper and there is no fuss in maintaining the lab, so we have more time to do the testing."
"This is an affordable product."
"The tool is not cheap, but it is not expensive."
"The pricing for LambdaTest is affordable, and one of the reasons we implemented it."
"The pricing could be made cheaper."
"It is affordable as compared to similar SaaS solutions."
"From the customer side, LambdaTest is cheaper for big company usage and works fine as other similar applications."
"LambdaTest is on the cloud, offers both free and paid plans which start at $19 USD per month."
