Performance Test Engineer at BETBY

Lighter on the RAM and has native Grafana support

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. Recently, I had a case where I was using another tool, and there wasn't enough memory for it because it required more RAM. k6 Open Source, on the other hand, is lighter and doesn't have a UI, which is beneficial. An engineer I was training could use k6 Open Source scripts even without my help. The tool is more efficient and has native support with Grafana, as both are developed by the same company. This integration enhances monitoring and loss ratio tracking. Thanks to its intelligent GUI, k6 Open Source's design is simpler, particularly for complex scenarios. When we need to manage hundreds of thousands or millions of transactions per minute, the solution becomes a game-changer compared to JMeter.

WorkSoft Certified Automation Engineer at Qualesce

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."

"Worksoft Certify has improved my organization by initially enabling us to transition from manual testers to automation, enhancing productivity by 50%."

"The most valuable features of Worksoft Certify are the way we can maintain the processes and sub-processes inside. We can immediately identify and replicate multiple objects in the application without having a major issue with it. We are able to do a lot of operations even with the solution being completely scriptless. That is a large advantage compared with other automation tools."

"For my processes, Worksoft makes them faster when creating scripts."

"The ability to work with the data, with recordsets, and plug those into the scripts is very easy and very powerful. We use it extensively."

"Worksoft Certify helps in reducing regression cycle time because manual testing takes substantial time and can lead to errors, and with Worksoft Certify, it will definitely help reduce resources as time and ROI will also increase."

"Worksoft Certify supports multiple interfaces and applications like SAP, Web, or Silverlight Java, and Mainframe. It is easily integrated."

"The most valuable feature is the ability to automate quickly and to maintain and update scripts."

"We love the Capture 2.0 feature. It seems to work very well."

More Worksoft Certify pros

Cons

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

"In terms of areas for improvement, I would suggest simplifying the input criteria when working on tables, as creating child record sets can become confusing."

"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."

"The updates for SAP Fiori have been great, where previously we saw a lot of issues. A year ago, it used to fail miserably."

"I would like to see the impact analysis integrated with the performance testing tool. We have multiple tools doing multiple items. I would like to have one common tool."

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

"We can't get the process intelligence module to work properly. We can't get the impact comment that analyzes the incoming development code to run, either. We've also had bugs in the CTM and execution manager in the past year. It took technical support a long time to resolve this issue. We escalated it so that the vice president of the company was included as well."

"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."

"Worksoft Certify's tech support's response time could be improved."

Pricing and Cost Advice

Information not available

"Purchasing and licensing are okay. Go for the perpetual licenses. In that way, you own a license, then you can purchase maintenance and support on top of that, so you don't have to pay every year for it. Even if you don't want it a contract with Worksoft Certify in the future, you will have your own license of it. Then, if your usage is not that much, you can have one or two perpetual licenses. However, if you want to run your processes, you will need more licenses, e.g., using the run-only licenses. They are really cheap compared to the full licensing."

"There is a cost involved to doing it, but once you get over the initial cost, then you'll start reaping the benefits and seeing that testing is getting done more quickly and efficiently. We are still early on with it, but the expectation and what we're seeing is that we will start seeing some savings coming out on the back-end once we have this done."

"The initial investment is probably a little high. It was a little hard for me to sell, but it was a one-shot deal and that's why it's so high. All we are doing now is paying annual maintenance, which we don't have to do if we don't want upgrades, but we do."

"We could use Certify to do robotic process automation, which is basically running a process on your correction system instead of your test system. Therefore, we may do that in the future."

"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."

"I don't have much idea about the pricing, but it is a licensed tool, and it is somewhat costly."

"Worksoft has paid for itself fives times over."

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