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

"LambdaTest supports multiple platforms like iOS across different devices and enables real-time testing."
"Stability-wise, I have not experienced any downtime or other performance issues."
"Without a doubt, LambdaTest is one of the big reasons behind our faster deployment and better team collaboration."
"It provides 2000+ browser-OS-resolution combinations to work with, which is perfect for our consulting firm, as we don't know what our clients may need."
"The technical support services are excellent."
"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."
"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."
"LambdaTest has made our testing process less tedious with automated parallel testing."
"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."
"As a platform corporation a primary strategic goal is to develop coherent tests across platforms, and this is where Ascential Test shines."
"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."
"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."
"Great support, powerful tool, easy enough for entry-level staff to use."
"Customer service is excellent; very helpful in addressing the issues and never hesitant in accepting the issues from their end; very responsive and quick to provide assistance."
"AscentialTest's object recognition in snapshots is a robust feature that goes beyond standard elements, even accurately identifying objects within Datawindows."
"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)."
 

Cons

"If possible to simulate the finger pinch, it would make it more realistic."
"The tool can improve its testing speed. Changing or switching to another mobile phone can be very slow on a real device."
"Their smart testing module needs improvement."
"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."
"The analytics over the automation dashboard can be more intuitive."
"Performing automation testing from UI is a little slow and could be improved."
"I would like to see all of the features available in the Freemium plan so that I can test them."
"The execution reporting can be improved for better integration between automation execution and accessibility platform reporting."
"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."
"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."
"It would be great if AscentialTest supported the license server being in the cloud."
"I would like to see an improvement in the user interface."
"Streamlining the retrieval of results from individual test set runs would be beneficial."
"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."
 

Pricing and Cost Advice

"It is affordable as compared to similar SaaS solutions."
"LambdaTest is paid per execution."
"The pricing could be made cheaper."
"LambdaTest is priced well, which is why we migrated to it."
"LambdaTest is on the cloud, offers both free and paid plans which start at $19 USD per month."
"From the customer side, LambdaTest is cheaper for big company usage and works fine as other similar applications."
"The product can be described as an averagely-priced solution."
"It is 60% cheaper and there is no fuss in maintaining the lab, so we have more time to do the testing."
"Once it starts generating ROI, which for us took between three and six months, one will not even think about the investment."
