- Use a
decorator: when all of the code in your test function body uses a mock. - Use a c
ontext manager: when some of the code in your test function uses a mock and other code references the actual function. - Use a
patcher: when you need to explicitly start and stop mocking a function across multiple tests (e.g. the setUp() and tearDown() functions in a test class).
