Principal Consultant ( Test automation - Performance testing) at TTC Global (TTC) at TTC at a tech services company with 51-200 employees
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.

Test Automation Architect at a tech vendor with 10,001+ employees
Integrated collaboration with automated test management has improved our agile workflows and continuously supports quality reporting
Visual Studio Test Professional could be improved as earlier we had flexibility in automation testing with TFS, which became a bit difficult moving to Azure DevOps. Additionally, in Visual Studio Code, we have an agent mode for GitHub Copilot, which is very helpful in testing or development phases, while Visual Studio's GitHub Copilot is a bit tricky and sometimes does not provide my desired output.For future improvements, I would like to see prompt fixing, as currently, if something goes wrong in Visual Studio, the fixing options are not always correct. If that intelligence is embedded, it would be very helpful.
