accessibility-developer-tools facilitates accessibility testing by providing a suite of rule-based audits and utility functions. It enables developers to assess web pages for common accessibility violations, such as missing ARIA attributes, incorrect contrast ratios, and inaccessible elements. The core component is the accessibility audit, which runs a collection of rules and reports any violations.
Notable features include a command-line runner for automated audits, seamless integration with Selenium WebDriver, and a flexible API for custom accessibility testing. The project's extensibility allows for the development of new audit rules and utilities tailored to specific needs. The clear and well-documented API simplifies integration into existing testing workflows.
