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.

Automation in testing processes sees improvement with multi-browser support and easier website interactions
Selenium HQ could improve by including a robust reporting framework, eliminating the need for external frameworks. The tool could simplify object identification, enabling users to generate XPaths without requiring detailed DOM understanding. Additionally, an automatic update mechanism for Selenium HQ would be beneficial, eliminating the need for manual downloads and updates of browser drivers when new versions are released.

Quotes from Members

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

Pros

"The standout feature of k6 is its strong focus on API performance testing."
"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."
"It has helped to complete tests in less time, which would not be possible relying on manual testing only."
"Selenium is the fastest tool compared to other competitors. It can run on any language, like Java, Python, C++, and .NET. So we can test any application on Selenium, whether it's mobile or desktop."
"Since Selenium HQ has multiple plug-ins, we can use it with multiple tools and multiple languages."
"Our platform runs into several thousand screens and a few thousand test cases, something which would typically take months to test manually. As of today, the entire process takes a little over two days to run."
"The most valuable feature of Selenium HQ is the ability to create automatic tests that can replicate human behavior."
"The ability to present your tests on a wiki page and hooking them up to the scripts/fixtures."
"I like that it is a robust and free open source. There is a lot of community support available, and there are a lot of developers using them. There's good community support."
"The main characteristic that is useful is that the tool is completely free."
 

Cons

"One area where k6 could improve is by introducing a GUI similar to JMeter."
"I don't have that much experience with it, but I know that Selenium is more used for websites. It is not for testing desktop applications, which is a downside of it. It can support desktop applications more."
"We can only use Selenium HQ for desktop applications which would be helpful. We are only able to do online based applications."
"Sometimes we face challenges with Selenium HQ. There are third party tools that we use, for example for reading the images, that are not easy to plug in. The third party add-ons are difficult to get good configuration and do not have good support. I would like to see better integration with other products."
"The stop control needs to be improved with a configuration tool to enable desktop support."
"If the test scenarios are not subdivided correctly, it is very likely that maintenance will become very expensive and re-use is unlikely."
"Shadow DOM could be improved and the handling of single page applications. Right now, it's a bit complicated and there are a lot of additional scripts required if you want to handle a single page application in a neat way."
"The solution can be improved by providing better reporting logs."
"Selenium HQ could improve by including a robust reporting framework, eliminating the need for external frameworks."
