HZ
Lead Systems Tester at Government of Ontario, Canada
Reliable test automation, and test data creation with efficient support
The solution can be improved by removing the need for object matching in the framework. The latest version has increased load time before testing can be run. The reason is that changes were made to how it works with the browser and the startup takes some time. Adjusting those changes to speed up the load time will improve the solution.

Practice Specialist at a government with 1-10 employees
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.

Pros

"It helps in automation by using better object recognition as compared to other tools in the market."

"It is 100% compatible with all sorts of database integrations and is compatible with all types of open source TFT-based applications, which makes it a great product to have."
"By automating regression test suites using this product, we were able to show time savings of more than 1200 hours in less than ONE year."
"The most valuable feature is the UI component tester."
"As it is built on Ellipse/Java and costs less than other tools, it is recommended."
"Robust API provides quick turnaround for developers to understand and automate functional test case quickly."

"Builds that took days to complete with in-house infrastructure were executed in a couple of hours."
"LambdaTest supports multiple platforms like iOS across different devices and enables real-time testing."
"Stability-wise, I have not experienced any downtime or other performance issues."
"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."
 

Cons

"The object repository used for identifying objects can be made better. It has been noticed that the RFT tool is unable to identify some objects, due to which we are unable to add them to the object repository."
"As many of our products are moving from PC to mobile, the most important thing that this solution needs is mobile app support."
"If the solution is running on Linux, there are some issues around application compatibility."
"If you look at today's current context, I wouldn't recommend RFT because there are far more advanced solutions and products available."
"The latest version has increased load time before testing can be run."
"The latest version has increased load time before testing can be run."
"With version 8.5 we faced workspace crash issues frequently."
"If in the future there is no support for mobile applications, then we will be using it less."
"If possible to simulate the finger pinch, it would make it more realistic."
"Performing automation testing from UI is a little slow and could be improved."
"LambdaTest's technical support comes in different tiers - most issues get resolved, but there's room for improvement with critical issues."
"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."
"It would be much easier for us to read the test if they provided dashboard analytics."

"We get logged out of the devices if there is some inactivity."
"For us, Cypress! It looks like the support for Cypress is not there."
 

Pricing and Cost Advice
