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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The main improvement is the lower cost of regression tests, where it may be about 30% more expensive in the first iteration but can save up to 40% or 50% in the next runs, and once the test scripts have been built, it is not necessary for the person executing the test processes to be an expert, allowing resources and costs to be optimized with lower costs in human talent and eliminating the barrier of functional knowledge."
"All the features in Selenium to automate the UI."
"Selenium HQ has helped us through its automation capabilities, because testing manually takes a lot of time and money."
"Our clients have realized benefits by reducing their testing cycle from three days to three hours through Selenium."
"It supports many external plugins, and because it's a Java-based platform, it's language-independent. You can use Java, C#, Python, etc."
"Selenium web driver - Java."
"It is a straightforward application to learn."
"The testing solution produces the best web applications."
"Geolocation testing is as straightforward as ticking checkboxes of browsers, operating systems, and countries."
"LambdaTest is a saving soldier for our company by offering us thousands of browsers and platforms to test on the cloud."
"It's user-friendly and offers valuable features for testing, making it a reliable tool."
"LambdaTest Selenium Grid has helped us radically reduce the manual testing effort and ensure browser compatibility."
"It is a scalable solution."
"The most valuable features are that it's essentially on-demand, and you only focus on getting the code that needs to be executed without having to worry about the OS, hardware, etc."
"The technical support services are excellent."
"Our test execution time was reduced to 16 mins from five hours when executed in parallel on multiple VMs. This has been extremely helpful!"
 

Cons

"One limitation of Selenium is that it is purely focused on web application testing."
"There are some network issues, as the line is not very clear. I continuously see failures in threads when it is running in parallel."
"I would like to see a better method handling. I mean methods/properties like Displayed, which should return false when there is no such element on the page instead NoSuchElementException, which has to be handled in my code – it should be provided with Selenium."
"Selenium HQ can be complex. The interface requires a QA engineer or an expert to use it."
"Due to its high rate in releases sometimes working code cannot be executed after an upgrade due to a new feature or different behaviour."
"The code that works in FF doesn’t work in Chrome."
"They should add more functionality to the solution."
"We'd like to see some more image management in future releases."
"I think Lambdatest is a valuable tool for our team and things that have room for improvement would be mobile app testing, as it can be an important addition to the tool."
"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."
"LambdaTest needs to improve its speed and memory because it takes a long time to load."
"The downsides I noticed include that the pricing was very good, but the visual quality of the image sometimes suffers."
"The tool can improve its testing speed. Changing or switching to another mobile phone can be very slow on a real device."
"LambdaTest needs to have native application testing, which would be a great help to my team."
"I feel that the automated screenshot testing takes a little longer on MacOS sometimes."
"Responsive testing UI is a bit cluttered, whereas the LT browser is much better to use."
