Cross-platform testing has accelerated releases and now needs smarter AI-driven test creation

The best features that BrowserStack offers include the ability to run manual and automated tests on real devices. We can create bugs, integrate it with other platforms like Jira or Azure, and use self-healing scripts with Selenium. We also have the test runs for different versions or with different frameworks, not just Selenium but with Playwright as well. Additionally, there are real-time dashboards and notifications sent when tests fail or when we need screenshots or recordings of test executions, and we can easily integrate this into our pipelines. BrowserStack has positively impacted my organization by providing an out-of-the-box solution for whole test executions across different projects for our automobile customers. We have worked on around twenty to thirty projects, and the need for a stable, customizable single test execution platform that supports different platforms has been met. It has helped manage the entire quality assurance of the product efficiently. The measurable improvements due to BrowserStack include a significant efficiency gain, allowing the whole team to collaborate on testing and communicate faster. Also, the easier integration with project management tools has been beneficial. The documentation of findings has improved, which helps us share insights with different project stakeholders.

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

"Hats off to their Customer Service."

"I've worked on testing integrations with BrowserStack, particularly with a platform called IT. This involves testing the registration process, including receiving verification codes on devices and phones. BrowserStack has been excellent for testing these integrations, providing a seamless workflow development experience."

"SPEED! Very fast, every browser, everything you need."

"The most valuable feature is that it provides parallel and cross-browser testing, enabling us to run tests on multiple browsers or devices simultaneously, and geolocation and globalization testing are valuable as well."

"More than a feature, it was the hardware support that we were able to get through the interfaces, and this helped us address a very rare requirement that had come up within our end customer's stack."

"The most valuable feature of BrowserStack is the ability to do manual testing."

"It is a scalable solution."

"The product support for different OS and mobile devices is awesome."

More BrowserStack pros

"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."

"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."

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

"The support docs are precise and you can get started with them easily."

"Automation and mobile testing have improved our efficiency."

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

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

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

More TestMu AI (Formerly LambdaTest) pros

Cons

"I would like application performance improvement to be better as, for me, it looked a bit slow."

"Initial set-up is easy, but if you start with automation, it's bit confusing and I found it tough to set-up."

"The solution is slow."

"I think a possible improvement for BrowserStack could be adding features such as sending SMS or making FaceTime calls because, as far as I know, those features are not available at the moment."

"I would like for there to be more integration with BrowserStack and other platforms."

"One of the biggest issues with BrowserStack is that if you don't have your network set up by the book, it's hard to get it to work with local desk machines."

"Occasionally, there are disruptions in the connection which can interfere with our testing processes, especially when testing on phones."

"BrowserStack should work on its Internet connectivity although issues only occur occasionally."

More BrowserStack cons

"Responsive testing UI is a bit cluttered, whereas the LT browser is much better to use."

"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."

"Sometimes, when multiple users use the tool simultaneously, it can slow down, affecting efficiency."

"The scalability is good with Amazon, but IBM had some issues."

"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 think Lambdatest is a valuable tool for our team and things that have room for improvement would be mobile app testing, as it can be an important addition to the tool."

"I didn't like the solution's technical support and how they communicated and tried to fix the issues of customers like me."

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

More TestMu AI (Formerly LambdaTest) cons

Pricing and Cost Advice

"My company found the product's license to be very compatible with our budget, and we pay 5,000 to 10,000 per year for licenses."

"There are different licenses available that can be customized. You can select the features that you want only to use which can be a cost-benefit."

"Compared to other solutions, BrowserStack is one of the cheapest."

"As for pricing, I can't provide a clear evaluation as I'm not directly involved in those discussions."

"BrowserStack could have a better price, but good things have a price."

"The price is fine."

"The price of BrowserStack is high."

"This solution costs less than competing products."

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

"LambdaTest is paid per execution."

"This is an affordable product."

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

"The tool is not cheap, but it is not expensive."
