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.

Offers versatility in testing automation while improvements can elevate its capabilities

I currently use Jenkins and Maven for framework development. The flow involves creating the project with Maven, and once test case execution is completed locally, we push the jobs to Jenkins. It automatically triggers the executions in Jenkins so everyone in the team can see the execution report and status. I would rate the solution at 60% out of 100. Previously, troubleshooting was difficult. When test cases fail for various reasons, logs cannot explain everything, but logging is very important to get the failure results. For logging, Amazon Q will suggest where the log code needs to be included. In Jenkins, when the code is executed and results are viewed, we can easily identify where the error occurred and troubleshoot efficiently, reducing time by two to three hours. I can recommend many packages with Selenium HQ. Wait conditions and numerous features are available to use. I recommend most of them to individuals. My overall rating for Selenium HQ is 7 out of 10.

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."

"A lot of time and cost has been saved by using Selenium automation because now we don’t need all browsers to be tested by manual testers, as just one automation script is required which can be run across different browsers and we only need one person to kick off the script execution."

"The initial setup is straightforward. Deployment took about seven months."

"There is nothing I cannot do with Selenium."

"Selenium gives me the ability to write my test using the programming environment I am already familiar with."

"Overall, this is a good product and I recommend it."

"Selenium is a valuable tool for web testing, and it integrates easily with frameworks like the Gauge framework, making it easier than others. It supports different programming languages, including Java and JavaScript."

"The most valuable feature of Selenium is how easy it is to automate."

"While it isn't without faults, Selenium is probably the best and most versatile web testing tool available."

Cons

"One area where k6 could improve is by introducing a GUI similar to JMeter."

"It takes such a long time to use this solution that it may be worth looking into other free solutions such as TestProject or Katalon Studio, or paid solutions to replace it."

"There are stability issues with Internet Explorer only."

"The solution needs to offer much more information in regard to performance testing using Selenium."

"Improvement in Selenium's ability to identify and wait for the page/element to load would be a big plus. This would ensure that our failed test cases will drop by 60%."

"The installation could be simplified, it is a bit difficult to install."

"In the future, Selenium should be able to automate desktop-based applications, as it is not currently able to handle non-web-based, Windows-based applications."

"It does require a programming skill set. I would like the product not to require a heavy programming skill set and be more user-friendly for someone without a programming background."

"I observed like batch execution issues and comparability issues like AngularJS app's etc."
