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 ease of learning and the small learning curve allowed us to scale the test scripts and the test suite quickly."
"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."
"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 product is easy to use."
"I have seen reduced maintenance due to smart locators, as it automatically finds locators for us even with minor application changes."
"It is a highly stable solution."
"It enabled us to cover our app in end-to-end tests very quickly with quality results."
"The Docker tunnel integration for local testing can be extremely useful to run on multiple instances in parallel."
"The real devices feature is the most valuable feature for us."
"It is a scalable solution."
"LambdaTest supports multiple platforms like iOS across different devices and enables real-time testing."
"The slow nature of a cloud platform was compensated with parallel testing, and now we are able to finish our testing job faster than it was before COVID."
"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."
"I am really glad that there are tools like LambdaTest that help freelancers like me to make sure everything is okay before finally making a website live."
 

Cons

"I get a little bit confused while creating new branches."
"The API testing integration is a bit lacking and can be improved."
"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."
"In the last couple of months, I have experienced some downtime where it wasn't working."
"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 is currently no room for improvement that I can identify as of now."
"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."
"Mobile application testing would be helpful for us."
"It would be much easier for us to read the test if they provided dashboard analytics."
"LambdaTest needs to improve its speed and memory because it takes a long time to load."
"It would be nice to have an API for visual regression testing."
"There is scope for improvement in service account usage, LDAP integration, and adapting new devices and features."
"Mobile application testing will be an added benefit for us if LambdaTest implements this really soon."
"Load flow compared to other stacks needs improvement."
"LambdaTest's technical support comes in different tiers - most issues get resolved, but there's room for improvement with critical issues."

"The tool offers a fixed pricing model for our company."
"I rate the product’s pricing an eight out of ten compared to other tools."
