Registering markers in pytest.ini - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of registering markers in pytest.ini?

Registering markers in pytest.ini helps pytest recognize custom markers, avoid warnings, and organize tests by categories or features.

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

Add the following under the [pytest] section:<br>

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

intermediate

Why should you register markers instead of just using them directly in test code?

If markers are not registered, pytest shows warnings during test runs. Registering markers documents their purpose and improves test clarity.

intermediate

What is the syntax to register multiple markers in pytest.ini?

List each marker on a new line under the markers key:<br>

[pytest]
markers =
    slow: marks tests as slow
    smoke: marks smoke tests
    api: marks API tests

beginner

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

Place pytest.ini in the root folder of your project so pytest can find it automatically when running tests.

What happens if you use a custom marker in pytest without registering it in pytest.ini?

A Pytest runs tests normally but shows a warning about unknown markers.

B Pytest ignores the marker and skips the test.

C Pytest throws an error and stops running tests.

D Pytest automatically registers the marker.

Pytest runs the tests but warns that the marker is unknown, encouraging you to register it.

How do you define a marker description in pytest.ini?

A [markers] marker_name = description

B marker_name = description of the marker

C markers = marker_name: description of the marker

D markers: marker_name - description

The correct syntax is under [pytest] section with 'markers =' followed by lines like 'marker_name: description'.

Where in the pytest.ini file do you register markers?

A Under the [test] section

B Under the [markers] section

C At the top of the file without a section

D Under the [pytest] section

Markers are registered under the [pytest] section in pytest.ini.

Which of these is a valid marker registration in pytest.ini?

A [pytest] markers = database: marks tests that use the database

B [markers] database = marks tests that use the database

C markers: database - marks tests that use the database

D [pytest] database = marks tests that use the database

The correct format is under [pytest] with 'markers =' and each marker on a new indented line.

Why is it helpful to register markers in pytest.ini?

A To speed up test execution

B To avoid warnings and document test categories

C To automatically generate test reports

D To disable tests permanently

Registering markers avoids warnings and helps document what each marker means.

Explain how to register a custom marker in pytest.ini and why it is important.

Think about the file structure and the syntax needed to tell pytest about your marker.

Describe the consequences of not registering markers in pytest.ini when using them in your tests.

Consider what pytest does when it sees a marker it does not recognize.
