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

"Testim introduces three services covering validation steps, eliminating the necessity to write complex code."
"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 automating smoke and regression tests have become easier and handier and manual efforts are saved."
"I have seen reduced maintenance due to smart locators, as it automatically finds locators for us even with minor application changes."
"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."
"We added Testim to our CI flow. It allows us to test only tasks that already passed sanity tests."
"The ease of learning and the small learning curve allowed us to scale the test scripts and the test suite quickly."
"LambdaTest supports multiple platforms like iOS across different devices and enables real-time testing."
"LambdaTest is easy to use, and the documentation provides all the needed information."
"We use the solution for automation testing and monitoring."
"Builds that took days to complete with in-house infrastructure were executed in a couple of hours."
"Without a doubt, LambdaTest is one of the big reasons behind our faster deployment and better team collaboration."
"The real devices feature is the most valuable feature for us."
"The support docs are precise and you can get started with them easily."
"The Docker tunnel integration for local testing can be extremely useful to run on multiple instances in parallel."
 

Cons

"The API testing integration is a bit lacking and can be improved."
"Testim sometimes fails due to stability issues. It doesn't always work consistently, especially after running multiple tests."
"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."
"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."
"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."
"The product's areas of improvement include pricing considerations and additional features related to visual testing and PDF handling."
"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."
"Mobile application testing would be helpful for us."
"If possible to simulate the finger pinch, it would make it more realistic."
"You cannot perform native-app testing, as they offer simulation for web testing only."
"The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers."
"I didn't like the solution's technical support and how they communicated and tried to fix the issues of customers like me."
"The analytics over the automation dashboard can be more intuitive."
"Sometimes, when multiple users use the tool simultaneously, it can slow down, affecting efficiency."
"Improvements on a platform need to happen on a timely basis...There should be some new features coming up or some performance improvisation over a period of time."
