Change detector tests

• tests that break during valid refactoring

When tests fail whenever the code changes, they are change detector tests. This problem occurs because mocking tests implementation, but not behavior.

Happy-path testing

• a type of software testing that uses known input and produces an expected output

Hook functions

• entry points to intercept pytest behavior at certain points and make changes

Line coverage

• calculated by dividing the total number of lines run divided by the total lines of code

Mock

• replacing a part of a system with mock objects

Mock objects are typically intended to be objects that are used in place of the real implementation. Mock objects are sometimes called test doubles, spies, fakes, or stubs.

Mock drift

• the interface to be mocked changes, while the mock in the test code doesn't

Monkey patch

• a technique used to dynamically update the behavior of a piece of code at run-time

• Python debugger

It is part of the Python standard library.
