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

Pros
