Featured Reviews

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 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."
"If you're a company that is working with any legacy systems, and you need automation with both web-based applications and terminal-based applications, the solution would be a good thing to use."
"We have used it for the web and Windows-based applications, and it is very productive in terms of execution."
"The best features of OpenText Functional Testing include descriptive programming, the ability to add objects in the repository, and its ease of use for UI compared to other tools."
"The solution is easy to integrate with other platforms."
"Micro Focus UFT One is a great tool and can be used in a variety of ways."
"The object repository is one of the best in the market, allowing creation of a repository useful for all tests."
"The initial setup is not complex."
"With certainty, the best feature of UFT is its compatibility with so many products, tools and technologies. It is a challenge currently to find a single tool on the market besides UFT that will successfully work for so many projects and environments. For example, UFT supports GUI testing of Oracle, PeopleSoft, PowerBuilder, SAP (v7.20), Siebel, Stingray, Terminal Emulator, Putty, and Windows Objects (particularly Dialog Boxes). Furthermore, UFT has the built-in functionality to import Excel input files."
 

Cons

"One area where k6 could improve is by introducing a GUI similar to JMeter."
"The overall design needs an entire overhaul. We prefer software designed to ensure the package isn't too loaded."
"When a debug session ends, UFT forces the user back to the main script. 90% of code development and issues occur in function libraries."
"There could be improvements in report export features similar to SmartBear."
"Object identification has room for improvement, to make it more efficient."
"The core application that we're using in our company is a bit special and resistant to automation."
"The product doesn't provide free training for the basic features."
"It could work with more browsers other than Internet Explorer, and could better handle new things like Ext JS."
"Additionally, there are hanging issues where it becomes unresponsive, which can be improved."
 

Pricing and Cost Advice

Information not available
"The price is only $3,000. I don't know how many QA analysts you would have in any given company. Probably no more than five or 10. So if it's a large corporation, it can easily afford $15,000 to $25,000. I don't see that being an issue."
"The licensing and pricing model is confusing."
"Compared to other products, the solution is very expensive."
"We have ALM licensing, and the tool is free of cost."
"The licensing cost is high. There are no additional costs to the standard license."
"The price is one aspect that could be improved."
"The tool's price is high."
"Its price is reasonable compared to other vendors."
