NalinGoonawardana - PeerSpot reviewer
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.
Kevin Copple - PeerSpot reviewer
Sr. Quality Assurance Project Manager at a tech services company with 501-1,000 employees
Has supported faster test execution and increased flexibility while offering room to improve support responsiveness
Reducing the levels of support is something they could continue to improve. They tend to have an entry-level person that may not be as familiar with the product that fields the calls, which creates another day of delay to get to the level that's needed. This is a common practice across most companies where you call, you get the entry-level person, and then they work their way up to help screen calls so that they are more focused.

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 stop automation is a great feature that is not generally supported by other solutions."
"The most valuable features are its support for multiple technologies, ease of coding, object repository, and ability to design our own framework. The recording playback feature allows those unfamiliar with coding to use the tool."
"The fact that it works with a vast number of technologies works for us because our internal customers use the tool for testing a lot of different applications."
"To me, the most valuable features were the OR and code compiler (VB script) to call the framework."
"There is a lot of flexibility and functionality in UFT."
"It's scalable on the enterprise level; I have already scaled a project with UFT One at enterprise level, and I am using it because it is very scalable compared to open-source tools and many other tools on the market."
"It's allowed us to perform functional testing (to verify a specific action or function of code) for each product update."
"Micro Focus UFT One is a great tool and can be used in a variety of ways."
 

Cons

"One area where k6 could improve is by introducing a GUI similar to JMeter."
"Sometimes it appears that UFT takes a while to open and sometimes will run slower than expected. Also, UFT uses a lot of memory. On this note, if you are running UFT on a virtual server I would add more RAM memory than the minimum requirements especially when using multiple add-ins. HP is pretty good about coming out with new patches to fix known issues and it pays for the user to check for new patches and updates on a regular basis."
"The problem with the solution is that you need to have highly specialized skills in order to make the scripts."
"They should include AI-based testing features."
"I would like to see more integration with LeanFT and use UFT for continuous integration. It's still a closed product."
"In cases of longer tests (in forms of so-called Mega Scripts), there can be a seriously huge usage of virtual memory by UFT that can lead to SystemOutOfMemory exceptions which are showstoppers and a huge annoyance."
"The licensing and pricing model is confusing."
"Micro Focus UFT One could improve by having more maintenance. Every time when we run the solution and develop something, the next time when we run it it doesn't recognize the object. I have to redesign the object again and then run the solution. It's really a headache, it's not consistent."
"I would want to see a significant improvement in the tool's features. The most significant enhancements are support for panel execution and integration with DevSecOps."
 

Pricing and Cost Advice

Information not available
"For the price of five automation licenses, you simply would not be able to hire five manual testers for two years worth of 24/7 manual testing work on demand."
"The price is reasonable."
"The licensing cost is high. There are no additional costs to the standard license."
"The licensing and pricing model is confusing."
"The tool's price is high."
"OpenText UFT One is a very expensive solution."
"Its price is reasonable compared to other vendors."
"The way the pricing model works is that you pay a whole boatload year one. Then, every year after, it is around half or less. Because instead of paying for the new product, you are just paying for the support and maintenance of it. That is probably one of the biggest things that I hear from most people, even at conferences, "Yeah, I would love to use UFT One, but we don't have a budget for it.""
