Daily Term: Mocking

Mocking

Mocking is a testing technique where dependencies (e.g., APIs, databases) are simulated to isolate the unit of code being tested. For example, a Python test might use the unittest.mock library to mock a database call, ensuring the test focuses on the function’s logic rather than the database. Mocking speeds up tests and removes external dependencies, but over-mocking can lead to unrealistic tests that miss integration issues.
