Testing Framework
A testing framework is a set of guidelines, tools, and libraries that provide a structured environment for writing, organizing, and executing automated tests in software development. It helps developers verify that code behaves as expected, catch bugs early, and ensure reliability through features like test runners, assertions, and mocking. Common types include unit testing frameworks, integration testing frameworks, and end-to-end testing frameworks.
Developers should learn and use testing frameworks to improve code quality, reduce manual testing effort, and enable continuous integration by automating repetitive test cases. They are essential in agile and DevOps environments for regression testing, ensuring new features don't break existing functionality, and supporting test-driven development (TDD) practices. Specific use cases include validating business logic in unit tests, checking API integrations, and simulating user interactions in web applications.
