Automation testing tools are applications designed to verify function and/or non-functional software requirements via automated test scripts. To help accelerate release velocity, improve project quality, and strengthen outcomes. Automation testing tools allow you to effortlessly create, run, and maintain tests and support a centralized view of analytics of test results.

As Agile and DevOps practices serve as the standard for software testing, establishing a clear-cut automation testing tool evaluation strategy is essential. Ultimately, this strategy needs to answer the following questions:

What features are you looking for?
Who’s going to use the tool for testing? Devs or QA teams?
Can it be integrated with CI/CD pipelines or toolchains?
Is it easy to maintain scripts and reuse test assets?
What is your team’s budget?
Where can you get support for technical issues?

Unfortunately, there isn’t really a one-size-fits-all automation tool; it really boils down to your team’s specific needs.

Select your best-fit automation testing tool

To pick the best automation testing tool for your team, don’t just blindly follow other teams’ success. Instead, look at your team’s specific needs, human resources, and future scalability to choose the best-fit option. For example, if your team’s testers are experienced developers, using Selenium or Appium for an automation framework is a good option since they allow you to build and scale from the ground up. However, if your team consists of mostly manual testers and you need a low-code solution to start, but one that can also grow and scale, ready-made frameworks like Katalon Studio can be a perfect solution.

The following is our list of the top 15 automation testing tools available to support your testing needs.
