Top 18 Open Source Automation Testing Tools

Open source automation testing tools involve running software programs that automatically execute test cases and generate test results without the need for human intervention.

Automated test softwares are a step forward from manual testing. It saves a lot of time and effort for humans, and it leaves no or very little room for testing errors. Once ready, automated tests can be run as many times as needed to test the same application, reducing the amount of time spent on manual testing.

For your convenience, we've compiled a comprehensive list of the top tools. You can do some research and decide which option is best for your project. There are both commercial and open-source test automation tools on this list. Almost all licensed tools, however, come with a free trial version that allows you to try out the tools before deciding which one is best for your needs.

Support for BDD allows for a better and more complete understanding of software behavior, which reduces the need for rework. This makes it easier for non-technical stakeholders to contribute to overall quality.

Ease Of Scripting And Reusability

A well-designed automated testing tool allows for greater reusability of test components as well as the creation of scripts that are simple to maintain and reuse across projects. There are several criteria to consider when choosing your tool, ranging from scripting time to object recognition and script execution speed to support for CI/CD tools like Jenkins and Bamboo.

Exploratory Testing Support

Exploratory Testing is an important part of test automation. Is auto-code generation with exploratory testing possible with this tool? Is it possible to record and playback web content? To help you with your exploratory testing, modern tools like QMetry Automation Studio offer features like automated screen capture and web recording and playback.
