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.

Antonio Oteri

IT Telecom Quality Senior Tester at TIM

Ability to automate tests across various platforms and simplifies test creation

From what I've seen with my colleagues who make the software selection, the prices for this software in Brazil are too expensive to be applied to anything but huge customers. I'm surprised because I was in charge of planning and control at the company before, when there was a manager there. Normally, the company has structural licenses that are based on the company they are selling to. I see that these companies cannot spend this money on Tricentis. I think Tosca is losing this type of market. They should have a different license policy for medium and small companies. The same happened in the past with SAP, which changed its policy and also made licenses for low.

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."

"Compared to other tools we have been looking at, you don't have to be a programmer to operate it, though it helps. It also a product that can be used by business people."

"The most important feature is its ability to support the technical automation of specific clients that we cannot use with other tools."

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

"We are satisfied with the support of Tricentis."

"The most valuable feature is being able to create a test case by recording some scenarios and then leasing that task case to other scenarios."

"It's been very helpful to have connectivity with mobile. The tool also identifies some of the actual changes from the recordings on the actual testing suite. That is something that I really like."

"The most valuable features of Tricentis Tosca are the ease of use, you do not need to program if you do not want to."

"To me, what stands out the most about Tricentis Tosca is that even if I'm not a technical tester, I could pick up on how to use it very quickly because of the mechanisms of the tool, for example, its scanning mechanism. I'm not so technical, but I'm able to maneuver through Tricentis Tosca and derive capability. It's a user-friendly tool. It's not very complex."

Cons

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

"While the initial setup was straightforward, we required assistance with the configuration to ensure that everything was done correctly."

"The issue is that even though the components are tightly integrated, object identification can be quite slow, sometimes taking five to ten seconds."

"The Vision AI implementation works very slowly, affecting the speed of our work."

"The source controls that are in Tricentis Tosca have some problems. For example, if you use Selenium or use Java-based application, it's easy to match code from two developers. However, if you're a developer and going to look at Tricentis Tosca, it's very difficult to use the source control measure."

"With regard to areas of improvement, report customization should be easier. It would be good if Tosca could provide standard reports for at least 20 variants. At present, there are only three to four variants. The mobile engine needs to be faster and easier to use; it is a bit cumbersome. Also, the object identification in the mobile engine needs improvement. I would like to see easy-to-use customizations for reports in the next release."

"The Vision AI implementation works very slowly, affecting the speed of our work. The exploratory testing feature is not working for version 2023.1, which we are currently using."

"There have been some setbacks because of upgrades. While Tosca has been around for a while, Tricentis has catered to smaller clients and I don't think they have done such a large, at-scale transition or transformation before or worked with a company like ours, which is doing an enterprise-wide transformation. When we go to their customer advisory-board meetings, upgrades have been an issue. They have been working a lot to make upgrades seamless."

"The product's test case management functionality needs enhancement."

Pricing and Cost Advice

Information not available

"The pricing and licensing of Tricentis Tosca were alright. Many customers look for end-to-end enterprise solutions, there were not many challenges with the pricing. However, the customers who are coming from Selenium or similar, feel they're paying a premium for this Tricentis Tosca license. If the right person is there for the implementation of the Tricentis Tosca, then it is one of the best tools in the market."

"A competitor of Tricentis Tosca: Katalon Studio, is very similar and offers lower pricing, though Tricentis Tosca offers more features and benefits."

"Pricing for Tricentis Tosca could be improved because it's very expensive."

"It is expensive."

"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."

"It is an expensive tool compared to other test automation tools. It has a lot of advantages over other tools."

"On a scale of one to ten, where one is very cheap and ten is very expensive, I rate the pricing a ten. The licensing model is based on a yearly basis."

"A yearly license costs around 20,000 euros."
