Automation revolutionizes testing efficiency and cost savings while ensuring smooth deployment
The challenges I faced while integrating Selenium HQ into my existing systems relate to historical data, which requires going back six years. I have to traverse if there were any challenges because I am sure if there were any, they must have been documented in our ALM documents. The multi-browser support of Selenium HQ impacts my testing process primarily since it is being used in Edge and Chrome browsers. It all depends on our customers. I haven't heard of any challenges with other browsers such as Opera or Mozilla Firefox, as these two browsers are what we primarily use. When we were doing these tests manually, it took several hours of effort, and those hours, when counted on the basis of person days, used to be maybe six or seven months of effort, which we can now do every day by running the pipeline. This has definitely saved a lot of money for us.

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.

"Automation testing improves the quality we deliver and reduce the time for regression testing."
"Since Selenium HQ has multiple plug-ins, we can use it with multiple tools and multiple languages."
