Assemble a comprehensive toolkit for automated accessibility testing of web applications using tools and libraries that have already been widely adopted and supported by the open source community. - Configure your codebase with ESLint accessibility rules to get feedback directly in the code and fix issues early in development. - Write tests with Testing Library to interact with applications the same way a user would, including users of assistive technologies. - Run a full set of automated checks against your running application by including the Axe-core accessibility engine in your e2e tests. Incorporate these tools into your development process using automated checks in your continuous integration pipeline at each stage of development and release to ensure your applications are accessible to all users.
