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.

Robust automation with reusable steps and seamless integration
The concept of reusable steps in Zeenyx AscentialTest has significantly enhanced our test automation efficiency. Encapsulating common actions into modular steps reduces redundancy in test scripts and ensures consistency across scenarios. This approach streamlines maintenance efforts, allowing updates to be applied universally, making our test suite more agile and adaptable to evolving project requirements. The concept of reusable steps is a key factor in maximizing reusability and maintainability in our test automation strategy. AscentialTest's object recognition in snapshots is a robust feature that goes beyond standard elements, even accurately identifying objects within Datawindows. This capability ensures precise interaction with various components of an application's interface, further enhancing the reliability and effectiveness of our automated tests.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Automation and mobile testing have improved our efficiency."
"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."
"LambdaTest is a saving soldier for our company by offering us thousands of browsers and platforms to test on the cloud."
"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."
"LambdaTest is brilliant."
"LambdaTest supports multiple platforms like iOS across different devices and enables real-time testing."
"The solution is very easy to understand and has a user-friendly UI."
"This product offers out-of-the-box geolocation testing in automation, which is amazing!"
"Zeenyx AscentialTest provides excellent support for PowerBuilder applications, with very powerful and flexible object recognition, a highly visual drag and drop environment for creating application objects from snapshots, and tests that are easy and quick to manage and maintain."
"AscentialTest's object recognition in snapshots is a robust feature that goes beyond standard elements, even accurately identifying objects within Datawindows."
"Customer Service: Zeenyx team provides a wonderful customer support for any kind of issues we face and they worked along with us and provided solutions as early as possible too."
"It’s been really easy to automate the same application TestComplete struggled with, and I have been able to automate two of our key applications in just a few months, even without taking their training."
"Productivity increased by almost 10 times after using AT for test automation as manually it was taking almost a day or three days (sometimes a week) effort to do data verification of expected and actual excel files with huge number of columns and rows (approximately 50 columns and thousands of rows)."
"I am a 30+ year IT professional and the level of support I have gotten has been unparalleled."
"As a platform corporation a primary strategic goal is to develop coherent tests across platforms, and this is where Ascential Test shines."
"The most valuable feature of AscentialTest for us is that it fully supports PowerBuilder."
 

Cons

"You cannot perform native-app testing, as they offer simulation for web testing only."
"I would like to see all of the features available in the Freemium plan so that I can test them."
"Mobile application testing would be helpful for us."
"Their smart testing module needs improvement."
"The scalability is good with Amazon, but IBM had some issues."
"Analytics could be better because as of now, it gives basic information on test status and build status."
"The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers."
"It would be nice to have an API for visual regression testing."
"Classes are not as object-oriented as I would like, but I am a programmer and not QA so I expect a lot."
"The product can be improved a little bit with regards to the UI as the panels are too many."
"Classes are not as object-oriented as I would like, but I am a programmer and not QA so I expect a lot."
"It would be better if the support for Web Tables and Siebel Tables are readily available and made more simpler as they are encountered quite often while automating the apps."
"I would like to see an improvement in the user interface."
"It would be great if AscentialTest supported the license server being in the cloud."
"The only thing I can't wait for is for Zeenyx to add automating Mobile apps."
"Limitations are found to be primarily in the ux of the tool; for example when in doubt one often right clicks in an unfamiliar product to get unstuck, and AscentialTest lacks some of these fineries."
