Autonomous testing involves several key features that ensure automated tests are executed programmatically, are repeatable, end with a validation, are stable for CI/CD, easy to understand, require minimal maintenance, and can run independently in parallel with other tests. TestRigor, a test automation tool, simplifies the creation of such tests by allowing users to write them in plain English from an end-user's perspective, making it accessible even to non-engineers. It ensures tests remain stable and repeatable by generating unique data automatically and integrates seamlessly with CI/CD platforms like Jenkins and GitHub Actions, reducing maintenance needs and enabling parallel test execution by default. TestRigor offers both a forever free open-source version and the option to request a demo to assess its suitability for different systems.
