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.
Shailesh-Parkhe - PeerSpot reviewer
Powerful automation tool with a user-friendly interface, codeless automation, and adaptability to complex business processes, particularly in SAP environments
The tool itself is highly effective, especially when it comes to comprehensibility for newcomers. Even during the initial learning phase, I found it remarkably user-friendly. It facilitates quick onboarding and training of new resources. It offers features for building automation scripts, such as search and certify capture. A notable advantage is that it doesn't rely on other tools like Micro Focus UFT or Micro Focus ALM for script execution. Worksoft can run independently without the need for support from Microsoft Office, although the option to use it for maintaining data exists. The tool also includes debugging features and comprehensive reporting capabilities, generating PDF reports for easy analysis.

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."
"We are able to automate, not just SAP, but the entire application ecosystem. If you take any company, SAP is the backbone, and if they use SAP ERP, then, there are multiple software applications, where some of them are SAP and some of them are non-SAP applications. Worksoft is one of the tools which can transcend across SAP and non-SAP applications. Non-SAP application include Java or .NET. Worksoft can seamlessly automate these applications."
"It is a lot easier to maintain test scripts on Worksoft Certify than on other testing tools that we have had in the past."
"It's pretty seamless with SAP and Salesforce because they've built in the field definitions and all the things that you need. You literally turn it on and execute your script and it records it. It's very simple. Then you can go back and put in some of the other functions. For example, instead of hard-coding field selections, you put in a data table so you can run it multiple times or with multiple data. It was actually written to work very well with SAP."
"One of the biggest advantages for this solution is codeless automation. Because it is codeless, you can train people within a couple of hours."
"It is very easy to maintain. With scripts, I can change one line and in one step. Whatever I want, I can do. I don't need to be an expert to use it."
"People who don't have coding knowledge are capable of doing automation with Certify. It reduces coding and scripting dependencies."
"What I found most valuable in Worksoft Certify is its identification feature. I also found its automation feature valuable."
"Worksoft Certify has good integration capabilities with third-party tools."
 

Cons

"One area where k6 could improve is by introducing a GUI similar to JMeter."
"With one of our applications where we do check-in, Worksoft is not able to identify the Java-based application. We raised the ticket, but we were unable to resolve this using Worksoft."
"We ran into some issues with the version that we were on during the initial setup. We ran into a bug on one version, then they upgraded us to a new version, and we got hit with another bug. So, they had to put us in a beta. That was a little frustrating. However, besides the bugs that we ran into, the install was pretty straightforward."
"The technical support has been good, but sometimes there are little delays. A lot of times when we need support, it's an emergency situation."
"Some features are missing from a testing perspective. You need to know how to connect everything to create requirements and stability metrics for the routine."
"We can use it for the web application, but we are facing stability-related challenges. The properties are getting changed. For example, when I am performing any operation on the text box but the development team has done some changes, our Worksoft scripts are getting changed. This is the main challenge that we are facing while developing tests for the web application in Worksoft Certify, where any changes in the backend are indirectly impacting our scripts. For the web application, there is a scarcity of resources. Unlike an SAP application that doesn't require much experience, for the web application, you require experienced people."
"One feature that we have been asking for has been to treat tests as code and store the source code for tests in a configuration management tool. Right now, for version control of testing, it's all internally within the tool. If we have a test of a business process and want to revive that test, our methodology now is purely manual work. We go into the tool, create a copy of the existing test, and call the next one: v2. Now, we have two of them and the only way you can tell them apart is by its naming convention."
"They have a scheduler in Execution Manager, but it is not customizable. Its UI needs a lot of improvement. The lights-out testing is a bit difficult with that particular tool, and it needs a lot of improvement. Of course, there are so many integration options with Worksoft for execution, but when it comes to Execution Manager, which is their own tool, there is a lot of scope for improvement."
"The technical support of the product is an area of concern where certain improvements are required."
 

Pricing and Cost Advice

Information not available
"Our ROI is primarily a reduction in testing time. The testing, when we were doing it manually, was 30 to 40 percent of the project's cost."
"The typical range that we see is between 50 to 90 percent improvement in speed capabilities. Another aspect comes with the depth that they're able to test. It increases their capabilities overall to test at a broader level."
"We saved $1.3 million using Worksoft Certify in 2017."
"By using automation, it reduced about 75 percent of the time when compared to any other tool."
"We have seen ROI by being able to free up and give time back to the business for other value-added work."
"It saves us time: approximately 50 percent."
"It is costly. It is a bit more expensive than Tricentis Tosca and other tools. If they reduce its price going forward and have partnerships with other vendors, it will grow like anything."
"Worksoft Capture 2.0 can help our customers to accelerate their automation development at least 40 percent faster than any other commercial tools available in the market."
