Offers good scalability and has the ability to integrate with various systems and services
One area where k6 could improve is by introducing a GUI similar to JMeter. While k6 is a powerful tool for performance testing, it leans heavily towards coding. Having a GUI, even if it is a low-code approach, could make it more accessible to a broader audience. It would be beneficial to strike a balance where basic tasks can be performed graphically through a user-friendly interface, while still allowing the flexibility for more complex operations through code, similar to how JMeter operates. This could enhance the user experience and make k6 more approachable for those who may not be as comfortable with scripting.
Tobias Roth - PeerSpot reviewer
Robust automation with reusable steps and seamless integration
The concept of reusable steps in Zeenyx AscentialTest has significantly enhanced our test automation efficiency. Encapsulating common actions into modular steps reduces redundancy in test scripts and ensures consistency across scenarios. This approach streamlines maintenance efforts, allowing updates to be applied universally, making our test suite more agile and adaptable to evolving project requirements. The concept of reusable steps is a key factor in maximizing reusability and maintainability in our test automation strategy. AscentialTest's object recognition in snapshots is a robust feature that goes beyond standard elements, even accurately identifying objects within Datawindows. This capability ensures precise interaction with various components of an application's interface, further enhancing the reliability and effectiveness of our automated tests.

Quotes from Members

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

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."
"It’s been really easy to automate the same application TestComplete struggled with. I have been able to automate two of our key applications in just a few months. I haven’t even taken their training."
"AscentialTest's object recognition in snapshots is a robust feature that goes beyond standard elements, even accurately identifying objects within Datawindows."
"If you use the PowerBuilder application, do choose AscentialTest without thinking twice."
"The most valuable feature of AscentialTest for us is that it fully supports PowerBuilder."
 

Cons

"One area where k6 could improve is by introducing a GUI similar to JMeter."
"The only thing I can't wait for is for Zeenyx to add automating Mobile apps."
"Streamlining the retrieval of results from individual test set runs would be beneficial."
"Classes are not as object-oriented as I would like, but I am a programmer and not QA so I expect a lot."
"I would like to see an improvement in the User Interface."
