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.

Has transformed testing by reducing scripting effort and enhancing productivity with advanced features

The self-healing feature of Tricentis Tosca needs significant improvement. Currently, it is static and not dynamic. For example, if a button in an application changes, Tricentis Tosca should be smart enough to detect the change and still execute the script seamlessly. Improvements are needed to ensure it responds dynamically to changes in the application.

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."

"You can quickly build automated testing, manage it, and have it run on a regular basis to ensure that there are no issues."

"The model-based scriptless automation is the most valuable feature because it needs less maintenance as compared to script-based automation."

"Tosca BI is important to make sure that our data integrity is in check and validated; to make sure our data is good. Our data is the number-one important driver for our company, so if that's not good, we have some big problems."

"With one click, it will scan all the elements on the screen, so that the user can select the required elements for automation tests."

"The initial setup was straightforward."

"I like how the modules are set up, particularly how you can use the screens you're automating. This automation helps save both time and money because we use less test capacity regarding personnel."

"This tool has test data management capability along with test management."

"The mainframe testing and UI automation are the most valuable aspects of the solution."

Cons

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

"I would like to see something in terms of AI capabilities."

"I would like to be able to manage different projects in one repository or have better data exchange between repositories."

"The solution needs to improve its simulation of mobile environments. Right now, that aspect is really lacking."

"The main area where there is room for improvement is how they do upgrades. Going through this current upgrade, we were delayed a month because we are using a third-party tool. It's called Tosca Connect by Tasktop. When this latest upgrade broke that relationship between the two, it took Tricentis a month to come back with a workable solution... Their whole upgrade process needs to be better and cleaner, from an end-user standpoint."

"You need to spend much more time learning the tool and how to use it, compared to others."

"I would like a better user interface."

"I would say the reporting part of the tool is an area of concern where improvements are required."

"I would like to see more implementation of AI on the self-healing aspect. That would be like the next step."

Pricing and Cost Advice

Information not available

"The licensing cost for Tricentis Tosca is expensive. It has multiple features, but to use all of its features, you have to pay for additional licenses."

"The pricing is high, but altogether it offers you the ability to automate all sorts of applications: desktop, web, mobile, etc."

"Tricentis Tosca is an expensive tool and the licensing is not simple."

"The price of Tricentis Tosca is approximately Є10,000 for one license. However, it used to be much cheaper, but they changed their license structure. It used to be a structure where if you bought a license you would receive one year of free support and maintenance. Now they only have a yearly license, and that is expensive."

"If you are purchasing less than five licenses, then the pricing is high. On a scale from one to ten, with one being low and ten being high pricing, I would rate this solution at eight."

"Licensing fees are paid on a yearly basis."

"I would like to see better costing packs. There are several features but USD $11,000 for one license is expensive."

"The tool's pricing is lower than that of other automation tools."
