Knowledgeable support, scalable, and stable
We use CrossBrowserTesting for testing our web-based applications We had some issues with the onboarding process and the cloud conductivity could improve. I have used CrossBrowserTesting within the past 12 months. CrossBrowserTesting is stable. I have found CrossBrowserTesting to be scalable.…

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

"When developing new pages that have questionable functionality or coding, we will often use CBT to test it in a browser. CBT works with our testing environment and development site."
"SmartBear has excellent, informative webinars, so keep an eye out for those."
"The screen shot portal is essential for an easy way to run tests across hundreds of browsers and retrieve screenshots which then indicate success or failure."
"At the moment, all our deploys depend on results of automation. If the tests are failing, then we know that something is wrong at the early stages of development."
"I am able to continuously test my new releases across browser versions without issues."
"The CrossBrowserTesting Selenium API and live test features have greatly improved our team's ability to quickly and effectively perform QA."
"I can run a page through the screenshot tool, then send a URL with the results to my team."
"CrossBrowserTesting improved my organization because it eliminates the need for a physical device with a tester to cover our used browsers."
"The technical support services are excellent."
"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 is a saving soldier for our company by offering us thousands of browsers and platforms to test on the cloud."
"With LambdaTest, we could see improvements in identifying errors before our customer does."
"Builds that took days to complete with in-house infrastructure were executed in a couple of hours."
"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."
"In case something goes wrong at LambdaTest end, the Support team is extremely responsive to analyze any platform-related issues."
"LambdaTest has made our testing process less tedious with automated parallel testing."
 

Cons

"A wider range of physical devices with more browser versions in the Selenium Grid would be great to insure users with out-of-date devices are able to interact with our sites."
"This solution would benefit from faster testing and support for more devices."
"Elements of 'real' mobile/tablet testing could be sped up, as I still sometimes experience lag, which no one loves."
"Sometimes, some of their instances fail, particularly in older versions of browsers."
"The "Getting Started" documentation for Selenium testing could be improved."
"The screenshot tool defaults to a screen layout instead of a full page test. I find it a bit cumbersome that I can't have it run a full screenshot as my default."
"Being able to test on real devices via the virtual connection is wonderful, but it can cause some lag and load time issues while testing."
"It would be useful if we can run the live-testing test cases on multiple platforms at the same time, instead of waiting for one session to finish."
"LambdaTest's technical support comes in different tiers - most issues get resolved, but there's room for improvement with critical issues."
"Mobile application testing will be an added benefit for us if LambdaTest implements this really soon."
"For us, Cypress! It looks like the support for Cypress is not there."
"Their smart testing module needs improvement."
"I feel that the automated screenshot testing takes a little longer on MacOS sometimes."
"Mobile application testing would be helpful for us."
"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."
"You cannot perform native-app testing, as they offer simulation for web testing only."
 

Pricing and Cost Advice

"A few intermediary pricing options for small QA teams would be nice, e.g., unlimited screenshots, "as you need it" parallel tests, etc."
"SmartBear offers bundles of products that work together."
"The lowest price point is very reasonable. It is also useful if only one person in the company needs to check on the browser display."
"CrossBrowserTesting offered the best value for its price."
"It is worth the pricing as the product is supported on multiple platforms and browsers."
"LambdaTest's pricing is cheaper than that of other similar platforms."
"From the customer side, LambdaTest is cheaper for big company usage and works fine as other similar applications."
"LambdaTest is paid per execution."
"It is 60% cheaper and there is no fuss in maintaining the lab, so we have more time to do the testing."
"I used the product for free."
"This is an affordable product."
"The pricing for LambdaTest is affordable, and one of the reasons we implemented it."
"LambdaTest is priced well, which is why we migrated to it."
