Performance Test Engineer at BETBY

Lighter on the RAM and has native Grafana support

The tool's big advantage is that it is more performance-test oriented for experienced testers who know what they are doing. In a normal working setup, performance engineers frequently work with DevOps and development teams. For these teams, k6 Open Source's syntax is much simpler and easier to understand and apply in the working process. Recently, I had a case where I was using another tool, and there wasn't enough memory for it because it required more RAM. k6 Open Source, on the other hand, is lighter and doesn't have a UI, which is beneficial. An engineer I was training could use k6 Open Source scripts even without my help. The tool is more efficient and has native support with Grafana, as both are developed by the same company. This integration enhances monitoring and loss ratio tracking. Thanks to its intelligent GUI, k6 Open Source's design is simpler, particularly for complex scenarios. When we need to manage hundreds of thousands or millions of transactions per minute, the solution becomes a game-changer compared to JMeter.

Good data security, allowing local installations to prevent data from going to the internet

There were a lot of issues we faced. One notable improvement would be better API integration within the tool itself, as we still rely on external tools like Postman. Additionally, expanding language support beyond C#, Java, and JavaScript to include Python would be beneficial. An AI feature that automatically detects automation object properties and suggests actions would be a great addition. So, in future releases, AI solutions for automated property identification would be helpful.

Pros

"The tool's big advantage is that it is more performance-test oriented for experienced testers who know what they are doing. In a normal working setup, performance engineers frequently work with DevOps and development teams. For these teams, k6 Open Source's syntax is much simpler and easier to understand and apply in the working process."

"The standout feature of k6 is its strong focus on API performance testing."

"The solutions's regression testing is very important for our company, as is the continuous integration process."

"The most valuable feature of Ranorex Studio is its user-friendly interface."

"The scalability is very good. It's probably one of the better tools I've seen on the market."

"I like the recording function and Ranorex Spy."

"Code Conversion is one of the great features because sometimes, the automation tool doesn't have the capability of maneuvering around two specific evaluations."

"Support is very quick. You can write to them and on the same day, they will respond. This is one of the best features."

"I'm from a UFT background, so Ranorex Studio has a similar feel in terms of how it handles objects. It just felt familiar even though I'd never seen it before. However, it doesn't have all the bells and whistles of UFT, but it's a pretty good start, and it's cost-effective."

"The most valuable feature of Ranorex Studio is the capture and replay tool. You don't need to do script testing. When you launch any application from Ranorex Studio it automatically captures these test case steps. The next time you can replay the tool the flow automatically happens again. For example, when you do the logging and all the activity will be captured by the tool, and re-execute the same step by using automatization."

Cons

"One area where k6 could improve is by introducing a GUI similar to JMeter."

"The automation of the SAP application could perhaps be improved to make it much simpler."

"For our purposes it requires integration with other products to get out the results in the format we want them. Adding this to the product could improve it."

"The object detection functionality needs to be improved."

"The solution's technical support team could be responsive."

"I'd like to know their testing strategies and to know what they can automate and what they can't. It can become pretty frustrating if you're trying to automate something that changes on a monthly or weekly basis."

"Other OS Support, Ranorex Spy performance improvement (Especially for Silverlight controls)."

"We are mainly working for manufacturing OEMs but the integration is not available. It would be a benefit if they built one integration tool for all the Teamcenter home servers and software as the main PLM data source. It is a simple process at this time, the integration could be made easier."

"Part of the challenge is that Ranorex's support is over in Europe, so we can't get responses on the same day. If we had support in the United States that was a bit more timely, that would be helpful."
