End-to-end testing validates the entire workflow of an application from the user's perspective. It ensures that frontend, backend, APIs, databases, and third-party integrations all work together as expected. This testing type simulates real-world usage scenarios to detect issues that unit or integration testing may miss. By validating the full system flow, end-to-end testing helps teams ensure reliability, identify bottlenecks, and reduce bugs before deployment.
