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.

User-friendly integration with support for Visual Studio enhances GUI testing capabilities
OpenText UFT Developer ( /products/opentext-uft-developer-reviews ) is user-friendly and integrates well with Visual Studio. The support is excellent. It is easy to implement tests with OpenText UFT Developer. We primarily use it for GUI testing and testing web applications with another application. This is the main usage for us. We also integrate it with the N-unit Framework ( /products/framework-reviews ), and they work well together.

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 most valuable feature of the solution is the number of plugins for object recognition. The predefined libraries allow us to automate tasks."
"The solution helps to accelerate software testing automation. It will help to reduce lead time and increase productivity and efficiency."
"One of the important features, which speeds up the automation testing development with LeanFT, is its object repository functions. Object identification are the most time-consuming aspect of building automation tests. LeanFT gives that out of the box. It helps you identify the objects and after that, once you got the object in place, then it's just about building the test scripts. So it reduces your development time significantly."
"The most valuable feature for me is the number of protocols that can be tested. It not only tests Web, but also SAP, Siebel, .Net, and even pdf."
"OpenText UFT Developer works well with record technology, making it valuable for recording."
"The most valuable features are the object repository."
"The most valuable feature is the Object Model, where you can directly pull up the object as a global or a local."
"I like the tool because we can still access the devices' distance. It's not important where you're working. For example, I can use it in Brazil, Chile, and other parts where people are working. After the pandemic, many companies use it for homework. I think using it to administer and manage the devices is very good and effective."
 

Cons

"One area where k6 could improve is by introducing a GUI similar to JMeter."
"Stability depends on the company's infrastructure and end-to-end infrastructure. When I used the tool in my project, we had a big problem with many users using it simultaneously."
"Object definition and recognition need improvement, especially with calendar controls. I faced challenges with schedulers and calendars."
"The pricing could be improved."
"It would be improved by adding a drag-and-drop interface to help alleviate the coding."
"UFT is like a flagship of testing tools, but it's too expensive and people are not using it so much. They should work on their pricing to make themselves more competitive."
"Easier connectivity and integration with SAP would be helpful."
"It is unstable, expensive, inflexible, and has poor support."
"UFT Developer is good, but it requires high-level development skills. Scripting is something that everybody should know to be able to work with this product. Currently, it is very development intensive, and you need to know various scripting languages. It would be good if the development effort could be cut short, and it can be scriptless like Tosca. It will help in more adoption because not every team has people with a software engineering background. If it is scriptless, the analysts who wear multiple hats and come from different backgrounds can also use it in a friendly manner. It is also quite expensive."
 

Pricing and Cost Advice

Information not available
"It is quite expensive and is priced per seat or in concurrent (or floating) licenses over a period of months."
"When we compare in the market with other tools that have similar features, it may be a little bit extra, but the cost is ten times less."
"Its cost is a bit high. From the licensing perspective, I am using a concurrent license. It is not a seed license. It is something that I can use in our network. It can also be used by other users."
"The licensing is very expensive, so often, we don't have enough VMs to run all of our tests."
"If I would rate it with one being inexpensive and ten being expensive, I would rate pricing an eight out of ten."
"It is cheap, but if you take the enterprise license, it is valid for both software items."
"The pricing is quite high compared to the competition."
"The price of the solution could be lowered. The cost is approximately $25 per year for a subscription-based license."
