pyproject.toml configuration in PyTest - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the pyproject.toml file in pytest?

The pyproject.toml file is used to configure pytest settings in a simple, centralized way without needing command-line options or separate config files.

intermediate

How do you specify the minimum pytest version required in pyproject.toml?

Use the minversion option under [tool.pytest.ini_options], for example: <br>

[tool.pytest.ini_options]
minversion = "7.0"

beginner

Which section header is used in pyproject.toml to configure pytest options?

The section header is [tool.pytest.ini_options]. Under this, you can set options like addopts, testpaths, and others.

intermediate

How do you add extra command-line options like verbose mode in pyproject.toml for pytest?

Use the addopts option under [tool.pytest.ini_options], for example: <br>

addopts = "-v --maxfail=2"

to run tests verbosely and stop after 2 failures.

intermediate

Can you configure test discovery paths in pyproject.toml? How?

Yes. Use the testpaths option under [tool.pytest.ini_options] to list directories or files where pytest looks for tests, e.g.: <br>

testpaths = ["tests", "integration"]

Which section header is correct to configure pytest in pyproject.toml?

A [tool.pytest.settings]

B [pytest.config]

C [tool.pytest.ini_options]

D [pytest.ini]

The correct section header for pytest configuration in pyproject.toml is [tool.pytest.ini_options].

How do you add verbose output to pytest runs using pyproject.toml?

A addopts = "-v" under [tool.pytest.ini_options]

B verbose = true under [tool.pytest]

C verbosity = 1 under [pytest]

D verbose = yes under [tool.pytest.ini_options]

You add command-line options like verbose mode using addopts = "-v" under [tool.pytest.ini_options].

What does the testpaths option do in pyproject.toml for pytest?

A Sets the output directory for test reports

B Lists plugins to load

C Defines the Python version to use

D Specifies directories or files where pytest looks for tests

testpaths tells pytest where to find test files to run.

Which of these is a valid way to stop pytest after 3 failures using pyproject.toml?

A maxfail = 3

B addopts = "--maxfail=3"

C stop_after_failures = 3

D fail_limit = 3

You use addopts = "--maxfail=3" to pass this option to pytest.

Is it possible to configure pytest entirely using pyproject.toml without command-line arguments?

A Yes, all common pytest options can be set there

B No, you must always use command-line options

C Only some options can be set in pyproject.toml

D pyproject.toml is only for plugin configuration

pytest supports configuring all common options in pyproject.toml under [tool.pytest.ini_options].

Explain how to configure pytest options using the pyproject.toml file.

Think about the section header and common options you can set.

Describe the benefits of using pyproject.toml for pytest configuration instead of command-line arguments.

Consider how configuration files help in projects.
