DevOps testing tools are crucial for maintaining consistent quality standards as development velocity increases. These tools integrate robustly with existing source control, CI/CD, and IDE solutions, allowing developers to access results within their working platforms. Some popular DevOps testing tools include BrowserStack, Jenkins, Opkey, Postman, Puppet, Cypress, Parasoft, Lambdatest, Apache JMeter, Testsigma, Selenium, K6, Appium, Docker, QA Wolf, Predator, Functionize, Katalon, Vagrant, Terratest, and Spacelift. These tools support various test types such as unit tests, end-to-end tests, linters, vulnerability scanners, and software composition analysis (SCA) engines to ensure that projects function properly even after future changes.
