Smart locators and small learning curve streamline test automation, minimizing maintenance and boosting efficiency.
Testim has a specific feature called a smart locator. Anyone experienced in test automation knows this is one of the most complex parts of developing automated scripts. The Testim feature automatically finds the locators, which helps us build stable test scripts. Stable scripts are crucial for receiving faster and more reliable feedback. I have also seen reduced maintenance due to smart locators, as it automatically finds locators for us even with minor application changes.

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:

"The pre-defined tests are a great help, specifically the custom JS test that allows us to be able to use custom code to test complicated elements or scenarios."
"Testim introduces three services covering validation steps, eliminating the necessity to write complex code."
"The product is easy to use."
"We added Testim to our CI flow. It allows us to test only tasks that already passed sanity tests."

"The automating smoke and regression tests have become easier and handier and manual efforts are saved."
"We primarily use the solution for business E2E testing, as it is fast and reliable, easy to maintain, and allows for the involvement of QA as well as Dev and BA."
"The real devices feature is the most valuable feature for us."
"LambdaTest is a saving soldier for our company by offering us thousands of browsers and platforms to test on the cloud."

Cons

"The UI could use a better design with a better user experience in mind."
