Unit is defined as a single behaviour exhibited by the system under test (SUT), usually corresponding to a requirement [definition needed].While it may imply that it is a function or a module (in procedural programming) or a method or a class (in object-oriented programming) it does not mean functions/methods, modules or classes always correspond to units.

Fixtures practically constitute the arrange phase in the anatomy of a test (AAA, short for arrange, act, assert). [11] [10] Pytest fixtures can run before test cases as setup or after test cases for clean up, but are different from unittest and nose (another third-party Python testing framework)'s setups and teardowns.

Therefore, unit test code is usually located in the same project or module as the code being tested. In object oriented design this still does not provide access to private data and methods. Therefore, extra work may be necessary for unit tests. In Java and other languages, a developer can use reflection to access private fields and methods. [13]
Test automation, mostly using unit testing, is a key feature of extreme programming and agile software development, where it is known as test-driven development (TDD) or test-first development. Unit tests can be written to define the functionality before the code is written. However, these unit tests evolve and are extended as coding progresses ...
System under test (SUT) refers to a system that is being tested for correct operation. According to ISTQB it is the test object. [1] [2] [3] From a unit testing perspective, the system under test represents all of the classes in a test that are not predefined pieces of code like stubs or even mocks. Each one of this can have its own ...
A test double may be used to test part of the system that is ready for testing even if its dependencies are not. For example, in a system with modules Login, Home and User, suppose Login is ready for test, but the other two are not. The consumed functions of Home and User can be implemented as test doubles so that Login can be tested.
