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."
"Testim introduces three services covering validation steps, eliminating the necessity to write complex code."
"The ease of learning and the small learning curve allowed us to scale the test scripts and the test suite quickly."
"We added Testim to our CI flow. It allows us to test only tasks that already passed sanity tests."
"The tool's most valuable feature is the recently added AI feature."
"It enabled us to cover our app in end-to-end tests very quickly with quality results."
"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 stability has been great; we can add stable tests very easily and improve our automation coverage, which allows us to deploy a new version into production every few days with minimum manual labor."
"The real devices feature is the most valuable feature for us."
"LambdaTest easily integrates with leading project management, bug tracking, and CI-CD tools like Jira, Asana, Jenkins, Circle CI, and more."
"LambdaTest has helped me gain more customers."
"With LambdaTest, we could see improvements in identifying errors before our customer does."
"LambdaTest Selenium Grid has helped us radically reduce the manual testing effort and ensure browser compatibility."
"LambdaTest was handy and easy enough to save us a lot of time, effort, and money."
"Without a doubt, LambdaTest is one of the big reasons behind our faster deployment and better team collaboration."
"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."
 

Cons

"The UI could use a better design with a better user experience in mind."
"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."
"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."
"There were some issues in the product's initial setup phase in regard to the area of documentation since it wasn't very easy to understand everything mentioned in it."
"Testim sometimes fails due to stability issues. It doesn't always work consistently, especially after running multiple tests."
"The API testing integration is a bit lacking and can be improved."
"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."
"Responsive testing UI is a bit cluttered, whereas the LT browser is much better to use."
"I would like to see all of the features available in the Freemium plan so that I can test them."
"The analytics over the automation dashboard can be more intuitive."
"LambdaTest needs to improve its speed and memory because it takes a long time to load."
"You cannot perform native-app testing, as they offer simulation for web testing only."
"Responsive testing UI is a bit cluttered, whereas the LT browser is much better to use."
"If possible to simulate the finger pinch, it would make it more realistic."
"Analytics could be better because as of now, it gives basic information on test status and build status."
