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.

Automation has delivered strong ROI with AI-driven test prioritization and parallel reporting

The best feature of Worksoft Certify is the automatic report generation. Unlike traditional tools like Selenium or Java-based frameworks where reporting often requires custom coding, Certify handles this natively. We are currently utilizing the 14.5 version, which has modernized these capabilities, though we frequently manage backward compatibility for clients still running on the 12.x version series.

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."

"The biggest feature is the fact that it's codeless, which makes it vastly usable by more people who are not even acquainted with IT at all."

"By using automation, it reduced about 75 percent of the time when compared to any other tool."

"That one defect we found easily saved us $1,000,000."

"Automating the User Acceptance Testing (UAT) process is the most valuable feature of this tool which helps us save loads of time for our clients on the projects and also generating testing and other reports."

"It saves us time, makes it so we are not as worried about changes which are going into the system, and we know that we have nightly runs to ensure that things are working."

"The Capture 2.0 feature is good. Our clients like using it. It does not take long to create documentation."

"Provides all the in-built functionalities and is a wonderful tool."

"Overall, I find the product cost-effective and it does bring the return on investment."

Cons

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

"From the features perspective, I find that there are functionalities missing in Worksoft Certify at the moment that I would like to see included in the future."

"I would rate the stability as a seven out of ten. If there is a test script I'm running five times, I have apprehension that it might not be successful five times."

"The stability is very bad. We have a lot of projects, which are run by our service integrators offshore in India."

"I am aware that they have some challenges with some of their support resources, especially offshore which is very common. I don't think this is specifically a Worksoft issue. It always seems to be a software issue, and I know that Worksoft is aware of this and they are trying to make some improvements."

"For points of improvement for Worksoft Certify, the first point is AI, the second one is technical support, and I feel that the UI improvements on Worksoft Certify over the last 11 years have been comparatively low compared to the competition in the market right now."

"It is poor for a web based application."

"Small changes in the HTML page design can impact the automation process, unlike SAP, where the script remains stable unless there is a functional change."

"An area that I would like to see improved is how the permissions are applied. If you're applying permissions groups to a user, one of the options is to delete the group entirely and lose the entire permission group, rather than just deleting the permission from the user, which seems a little silly. In my opinion, that whole module of permissions is very confusing and lends itself to common errors."

Pricing and Cost Advice

Information not available

"I can only judge based on the situation that we had around six years ago when we did the tool evaluation. Worksoft was not the cheapest, but it provided the value. For 25 concurrent licenses, we paid more than €400,000, so it was not cheap. In the end, if you see how much time you are saving and compare it with others, its price is okay. We had also compared its cost with the licensing costs for HP and Tricentis, and they were at another level. Now, as we have already booked the licenses, we only have to pay an annual maintenance fee, which is 70%, and that is okay."

"It is expensive compared to some of the other automation tools in the market. However, the benefits and ROI has proved that it has been a good investment."

"Worksoft Certify is slightly more expensive compared to other automation tools that are available on the market. However, the majority of the clients who are utilizing this solution, don't care much about the price. The main aspect the clients look for is its stability and reliability on the automation and whether they are able to rely on the automation scripts."

"We would purchase more licenses right now if they were cheaper. Pricing is a little bit of a hindrance."

"We have seen ROI by being able to free up and give time back to the business for other value-added work."

"Worksoft Capture 2.0 can help our customers to accelerate their automation development at least 40 percent faster than any other commercial tools available in the market."

"It is costly. It is a bit more expensive than Tricentis Tosca and other tools. If they reduce its price going forward and have partnerships with other vendors, it will grow like anything."

"We have an annual license for this solution. The product is very expensive."
