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

"We like the model device factory for iOS and Android devices."

"The BrowserStack interface is easy to use and the webinar has a lot of information."

"Local testing for products with no public exposure is an advantage in development."

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

"BrowserStack has lots of devices to choose from."

"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."

"When we reached out to BrowserStack, they were great."

"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."

More BrowserStack pros

"The most valuable features are that it's essentially on-demand, and you only focus on getting the code that needs to be executed without having to worry about the OS, hardware, etc."

"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."

"With LambdaTest, we could see improvements in identifying errors before our customer does."

"The real devices feature is the most valuable feature for us."

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

"Without a doubt, LambdaTest is one of the big reasons behind our faster deployment and better team collaboration."

"The UI is pretty clean and easy to navigate, and we were able to figure it out very quickly."

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

More TestMu AI (Formerly LambdaTest) pros

Cons

"There is room for improvement in pricing."

"While I was testing I was not 100% sure it was properly mimicking the browsers or not."

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

"While I was testing I was not 100% sure a that was properly mimicking the browsers or not. We had some issues with a browser, and the reason was the browser itself does not provide any support. If the local system does not provide any support, I think this was the problem. There should be better integration with other solutions, such as JIRA."

"If you are inactive for 30 minutes, the solution will close."

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

"Customer support could be better. We tried to implement and explore this product with the vendor or reseller's help, but we haven't had any good response about the product."

"It is difficult to use for someone who has little to no experience."

More BrowserStack cons

"LambdaTest needs to have native application testing, which would be a great help to my team."

"The execution reporting can be improved for better integration between automation execution and accessibility platform reporting."

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

"Mobile application testing will be an added benefit for us if LambdaTest implements this really soon."

"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."

"Mobile application testing would be helpful for us."

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

"It would be much easier for us to read the test if they provided dashboard analytics."

More TestMu AI (Formerly LambdaTest) cons

Pricing and Cost Advice

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

"This solution costs less than competing products."

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

"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."

"The price of BrowserStack is high."

"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."
