Recording limitations and remote access challenges have affected desktop application testing
Katalon Studio has proven effective in our deliverables, particularly in designing the framework where other tools typically require coding in client libraries such as Python or Java. With Katalon Studio, there is no such complexity, allowing us to organize projects modularly based on folder structures without needing to write separate code. The self-healing feature for web application automation and its built-in CI/CD ecosystem integration eliminates the need for external tools for pipeline setup. Katalon Studio excels in CI/CD integration, providing an inbuilt ecosystem without the need for external setup, and it features a postings structure along with keyword and library availability. Newcomers to the team can easily adapt to the setup or project structure, which contributes to its popularity, along with its low-code or no-code capability that allows for a comprehensive platform supporting web, mobile, API, and desktop automation. The self-healing mechanism for test cases autonomously identifies issues with locators and ensures they continue functioning, which is impressive, along with the robust object repository. Katalon Studio has significantly aided our team, especially when clients expect deliveries for CI/CD integration that requires automation test scripts to run on a daily schedule. The self-healing feature automatically identifies available locators for elements in the DOM, ensuring that test cases remain functional. Katalon Studio has positively impacted our organization by facilitating faster delivery when clients have urgent requirements. We can deliver quickly based on urgency due to the features Katalon Studio provides. This has led to significant reductions in time spent on framework configuration, designing, and training individuals who are unfamiliar with the tool, helping us save both time and costs.

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 recording feature of this product is very valuable for our testing purposes."
"My advice for those looking into using Katalon Studio is that, regardless of time or efficiency, it is seamless for any kind of automation project because Katalon Studio allows you to automate things with any kind of software you want to integrate and testing is comparatively easy compared to other tools or software available."
"Katalon is very easy to record and then we can use the identifiers very easily, as Katalon automatically gets you all the identifiers and is very user-friendly, with excellent object finding and very fast automation that does not require you to be overly proficient in coding."
"Katalon Studio has positively impacted my organization by helping the team reduce manual regression effort and improve release confidence by catching UI issues earlier."
"The initial setup is pretty straightforward and easy enough to complete."
"Katalon Studio's biggest advantage is its price. It's a good tool for the price, albeit with some limitations when you compare it with tools like Tricentis Tosca."
"Katalon Studio has positively impacted our organization by helping our team save a lot of time by automating repetitive testing, allowing us to test faster, find issues earlier, improve test accuracy, and reduce manual effort."
"The most valuable feature is that the browser and the API testing is available in a single tool, and I don't have to look at other options."
"With LambdaTest, we could see improvements in identifying errors before our customer does."
"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."
"LambdaTest is a saving soldier for our company by offering us thousands of browsers and platforms to test on the cloud."
"We use the solution for automation testing and monitoring."
"It provides 2000+ browser-OS-resolution combinations to work with, which is perfect for our consulting firm, as we don't know what our clients may need."
"The solution is very easy to understand and has a user-friendly UI."
"Using LambdaTest, we could run all our functionality tests across various browsers, OS, and resolutions."
"LambdaTest Selenium Grid has helped us radically reduce the manual testing effort and ensure browser compatibility."
 

Cons

"Stability is one of the main issues with the system crashing if there's a new release that hasn't been sufficiently tested."
"There could be many improvements, however, I have not noted them down at this moment."
"Because of these issues, we are not able to integrate this solution into our platform."
"The solution can be further improved with better loading time."
"The reporting is very good, but it could be better."
"We have been seeing some error pop-ups that are difficult to understand why they were triggered."
"One improvement would be if it could support more programming languages such as JavaScript or Python. Right now, it is only on Groovy, which I think is not a too popular language."
"I would like if this tool can work without any problems for React Native."
"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."
"We get logged out of the devices if there is some inactivity."
"The scalability is good with Amazon, but IBM had some issues."
"Performing automation testing from UI is a little slow and could be improved."
"I would like to see all of the features available in the freemium plan so that I can test them."
"For us, Cypress! It looks like the support for Cypress is not there."
"You cannot perform native-app testing, as they offer simulation for web testing only."
