Featured Reviews

NalinGoonawardana - PeerSpot reviewer
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.
PrabhuKrishnamoorthy - PeerSpot reviewer
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 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."
"The model-based scriptless automation is the most valuable feature because it needs less maintenance as compared to script-based automation."
"It offers many features, such as risk-based testing and scenario creation using Kafka."
"The tool's most valuable feature is Tosca Commander."
"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 valuable features of Tricentis Tosca are the Salesforce scanning. There are two scanning for Salesforce applications. There is Salesforce scanning and normal application scanning. Object identification has been really useful in Tricentis Tosca."
"We have multiple applications, and it supports parallel execution. It has mobile automation."
"The scriptless automation tool is one of the important features."
"As a codeless automation tool, the product offers a user-friendly experience without requiring extensive coding knowledge. Users can easily handle various applications, including web applications, SAP applications, Windows applications, and even Salesforce applications, without manual coding."
 

Cons

"One area where k6 could improve is by introducing a GUI similar to JMeter."
"It can be quite expensive."
"The product's test case management functionality needs enhancement."
"First, Tricentis could improve Tosca's Linux scripting. We can automate Linux scripting, but there are a few commands that Tosca doesn't support. DVS support and the object identification mechanism could also be better."
"Product quality has declined as it grows, and its updates aren't without fault. The process of resolving problems has slowed, and as it expands into other areas like NeoLoad and other testing tools, the product becomes more complicated. It used to be a small firm with a clear goal, but as it grows, the quality has been affected."
"When using it with iOS devices, I cannot start automation directly and must use a remote machine."
"They should have a different license policy for medium and small companies."
"It is quite difficult to integrate the solution with other tools."
"I would like to see better integration with other testing tools."
 

Pricing and Cost Advice

Information not available
"I'm not sure if I'm at liberty to talk about the pricing, but it has some significant costs. For example, you have to pay a license and maintenance fee. Then the rest of the terms are negotiable. We have to consider what we need and what benefit we get from it."
"​It is an expensive tool compared to other test automation tools. It has a lot of advantages over other tools."
"I am satisfied with the cost."
"Although the product is slightly more expensive than tools, its automation capabilities and reduced scripting needs justify the cost."
"The tool is quite expensive."
"My understanding is that it's an expensive product, although I don't know the specifics with regards to pricing."
"We have around 200 [concurrent] licenses and the cost around $1.4 million a year."
"I would rate the pricing a seven out of ten, where one is cheap, and ten is expensive. It is on the higher side."
