pytest.ini configuration - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the pytest.ini file?

The pytest.ini file is used to configure pytest settings globally for a project. It helps set options like test paths, markers, and command-line flags so you don't have to type them every time.

How do you specify the directory where pytest should look for tests in pytest.ini?

You use the testpaths option under the [pytest] section. For example:<br>

[pytest]
testpaths = tests

This tells pytest to look inside the tests folder for test files.

What is the use of the markers option in pytest.ini?

The markers option lets you declare custom markers to label tests. This helps organize or selectively run tests. For example:<br>

[pytest]
markers = slow: marks tests as slow to run

intermediate

How can you add command-line options permanently using pytest.ini?

You can add default command-line options using the addopts setting. For example:<br>

[pytest]
addopts = -v --maxfail=2

This runs tests in verbose mode and stops after 2 failures.

beginner

Where should the pytest.ini file be placed in your project?

Place pytest.ini in the root folder of your project. Pytest automatically finds it there and applies the settings when you run tests.

What section header must be used in pytest.ini to configure pytest?

A [settings]

B [config]

C [pytest]

D [test]

The correct section header is [pytest]. This tells pytest to read the options under this section.

Which option in pytest.ini sets the default command-line arguments?

A addopts

B markers

C testpaths

D log_level

The addopts option lets you specify default command-line arguments for pytest.

How do you declare a custom marker named 'slow' in pytest.ini?

A marker = slow

B addopts = slow

C testpaths = slow

D markers = slow: marks slow tests

You declare custom markers under the markers option with a description.

Where should you place the pytest.ini file for pytest to find it automatically?

A In the root folder of the project

B Inside the tests folder

C In the home directory

D In the Python installation folder

pytest looks for pytest.ini in the root folder of your project.

What does the testpaths option do in pytest.ini?

A Specifies which tests to skip

B Specifies directories where pytest looks for tests

C Sets the verbosity level

D Defines test markers

testpaths tells pytest which directories to search for test files.

Explain how to configure pytest to run tests only from a specific folder using pytest.ini.

Think about telling pytest where to look for tests.

Describe how to add a custom marker and use it to label tests in pytest.ini.

Markers help organize tests by labels.
