Top 20 DevOps Testing Tools to Try in 2024

devops testing tools

DevOps is the discipline of shortening the software delivery lifecycle by building tools and systems that allow changes to be developed continually using an iterative process. It brings dev and ops teams closer together, tightening feedback loops and allowing work to progress more smoothly through the delivery pipeline.

DevOps is often associated with concepts such as CI/CD, IaC, containers, and cloud, but testing is also a crucial part of successful DevOps implementations. Selecting the right testing tools ensures you can efficiently validate changes and maintain consistent quality standards, even as development velocity increases.

For this article, we’ve gathered together 20 test-oriented DevOps tools and DevOps testing solutions that you can use to catch bugs and errors before they reach users. We’ll explain what each tool contributes to the QA process so you can find the right options for your projects.

What to look for in a DevOps testing tool?

Manual and automated tests are a cornerstone of software quality and security. Unit tests, end-to-end tests, linters, vulnerability scanners, and software composition analysis (SCA) engines allow you to demonstrate that your projects function properly, not just today but also after future changes.

Test suites also provide valuable feedback to developers, removing pressure from dev cycles by letting code authors confirm that their work doesn’t introduce any regressions.

To ensure you can achieve these testing outcomes, you need tools that can integrate robustly with your processes. Look for options that are compatible with your existing source control, CI/CD, and IDE solutions, allowing devs to access results within the platforms where they’re already working. 

DevOps testing tools also need to offer clear documentation, dependable performance, and good support options so developers can use them effectively without becoming frustrated.
