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:
 

Pros

"The REST API features allowed integrated testing for select products to quickly make calls and test the UIs with API calls while the CLI allows us to matrix the grid function across browsers."
"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."
"Testim introduces three services covering validation steps, eliminating the necessity to write complex code."
"The automating smoke and regression tests have become easier and handier and manual efforts are saved."
"It is a highly stable solution."
"The feature I like most about Testim is the record and playback capability, which does not require writing a lot of code."
"The tool's most valuable feature is the recently added AI feature."
"The product is easy to use."
"We use the solution for automation testing and monitoring."
"With LambdaTest, we could see improvements in identifying errors before our customer does."
"Geolocation testing is as straightforward as ticking checkboxes of browsers, operating systems, and countries."
"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 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 a saving soldier for our company by offering us thousands of browsers and platforms to test on the cloud."
"LambdaTest made a great fit here when considering the latest browsers on the product."
"This product offers out-of-the-box geolocation testing in automation, which is amazing!"
 

Cons

"The UI could use a better design with a better user experience in mind."
"There is currently no room for improvement that I can identify as of now."
"The accessibility reporting features could be more robust to be reported at the script level and allow users to map down to the step level."
"Faster scripting would be beneficial, as test creation is faster now."
"In the last couple of months, I have experienced some downtime where it wasn't working."
"The UI could use a better design with a better user experience in mind, for instance - instead of going in and out of the editor every time I want to view test data for a test, I could just view the test data in the table, or the ability to copy steps through tests."
"Testim sometimes fails due to stability issues. It doesn't always work consistently, especially after running multiple tests."
"There are common properties between multiple elements that we should be able to edit - such as 'when this step fails,' 'when to run this step,' and 'override timeout'. I should be able to update these properties if I select multiple elements."
"You cannot perform native-app testing, as they offer simulation for web testing only."
"Performing automation testing from UI is a little slow and could be improved."
"The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers."
"The execution reporting can be improved for better integration between automation execution and accessibility platform reporting."
"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."
"Their smart testing module needs improvement."
"Mobile application testing would be helpful for us."
