A testing pyramid is a visual representation of different layers of testing that ensure an application is robust, reliable, and maintainable, consisting of unit tests, integration tests, and end-to-end tests, providing comprehensive coverage, efficient resource allocation, and faster feedback loops.
Test automation is essential for ensuring application quality and reliability, involving automated tests to validate code behavior, reducing manual testing time and errors. It includes unit tests, integration tests, and end-to-end tests, with popular frameworks like Jest, Pytest, and Cypress, increasing development speed and efficiency.
