Test naming conventions in PyTest - Cheat Sheet & Quick Revision

Recall & Review

beginner

Why is it important to follow test naming conventions in pytest?

Following test naming conventions helps pytest automatically discover tests, makes tests easier to understand, and improves collaboration among team members.

beginner

What prefix should pytest test functions start with?

Test functions should start with the prefix test_ so pytest can recognize and run them automatically.

beginner

How should test names be written for clarity?

Test names should be descriptive and clear, explaining what the test checks, often using underscores to separate words, e.g., test_user_login_success.

intermediate

Can pytest test classes have any name?

No, test classes should start with Test (capital T) and should not have an __init__ method to be discovered by pytest.

beginner

What happens if a test function does not start with test_ in pytest?

Pytest will not recognize or run the function as a test, so it will be ignored during test execution.

Which prefix should pytest test functions start with?

A verify_

B check_

C test_

D run_

Pytest automatically discovers test functions that start with the prefix test_.

What is the recommended prefix for pytest test classes?

A Test

B test

C testcase

D classTest

Test classes should start with a capital T as Test for pytest to discover them.

Why should test names be descriptive?

A To make tests run faster

B To avoid errors

C To reduce code size

D To help understand what the test checks

Descriptive test names help developers quickly understand the purpose of the test.

What happens if a test function is named check_login instead of test_login?

A Pytest ignores it

B Pytest runs it normally

C Pytest runs it twice

D Pytest throws an error

Pytest ignores functions not starting with test_ during test discovery.

Which of these is a good test function name?

A testUserLogin

B test_user_login_success

C userLoginTest

D loginTest

Using lowercase with underscores and descriptive words like test_user_login_success follows pytest naming conventions.

Explain why pytest test functions must start with test_ and how this affects test discovery.

Think about how pytest finds tests to run.

Describe best practices for naming test functions and classes in pytest to improve readability and maintainability.
