Lead Systems Tester at Government of Ontario, Canada

Reliable test automation, and test data creation with efficient support

The solution can be improved by removing the need for object matching in the framework. The latest version has increased load time before testing can be run. The reason is that changes were made to how it works with the browser and the startup takes some time. Adjusting those changes to speed up the load time will improve the solution.

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.

Quotes from Members

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

Pros

"Test automation is most valuable because it saves a lot of time."

"IBM Rational Functional Tester is very contextual."

"It is compatible with all sorts of Dark Net applications. Its coverage is very good."

"The most valuable feature is the UI component tester."

"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."

Cons

"They need to do a complete revamp so that even a non-technical person can manage the tool."

"As many of our products are moving from PC to mobile, the most important thing that this solution needs is mobile app support."

"The latest version has increased load time before testing can be run."

"If the solution is running on Linux, there are some issues around application compatibility."

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

Pricing and Cost Advice

"Licensing is good but the prices for the products are expensive. A single-user license may go for something like $10,000 to $30,000. There are no additional costs, and support is included within that price."
