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.

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."
"I like the Help feature in UFT One. For example, if you are navigating a particular window, where there are different options. One wouldn’t know the purpose of every option, but there is no need to search because that window contains a Help button. If you click on that Help button, it directly navigates to the respective help needed. VBScript is very easy to understand and easy to prepare scripts with minimal learning curve."
"With certainty, the best feature of UFT is its compatibility with so many products, tools and technologies."
"Has improved our organization by allowing us to obtain fast, detailed information about the behavior of our products and to supply this to the customer, enabling us to work together without the need for special programming knowledge."
"UFT has improved our ability to regression test, freeing up the test team to work only on the new portions of the software without having to worry that they are introducing new errors in other areas without knowing it."
"This tool is awesome for automation even though it is expensive."
"OpenText Functional Testing has an impressive ability to connect to mobile devices and its ability to test so many different types of software, whether it be mainframe, APIs, mobile, web, or desktop."
"This product is easy to use, understand, and maintain."
"The initial setup is relatively easy."
 

Cons

"One area where k6 could improve is by introducing a GUI similar to JMeter."
"The UA objects are sometimes hard to recognize, so the coverage should be increased."
"The price is very high. They should work to lower the costs for their clients."
"It often crashes."
"Previously, the product was a script-based solution. Presently, the tool offers non-script, no-code, or low-code functionalities, making it an area where improvements are required."
"The core application that we're using in our company is a bit special and resistant to automation."
"The solution needs better marketing, training, promotion, and visibility because it is not visible."
"Needs to improve the integration with the CI/CD pipeline (VSTS and report generation)."
"There are scenarios where the tool freezes and locks the user out."
 

Pricing and Cost Advice

Information not available
"Compared to other tools in the market, UFT One is very competitive. The recent Covid pandemic situation also hit customer budgets significantly, so Micro Focus offered some discounted prices, which is definitely competitive."
"The licensing cost is high. There are no additional costs to the standard license."
"The pricing of the product is an issue."
"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."
"Compared to other products, the solution is very expensive."
"The licensing and pricing model is confusing."
"The tool's price is high."
"The solution is priced reasonably for what features it is providing. However, it might be expensive for some."
