Markers for categorization in Selenium Python - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a marker in pytest and why is it useful?

A marker is a label you add to tests to group or categorize them. It helps run specific sets of tests easily, like all slow tests or all login tests.

beginner

How do you apply a marker to a test function in pytest?

Use the @pytest.mark.<marker_name> decorator above the test function. For example, @pytest.mark.slow marks the test as slow.

beginner

How can you run only tests with a specific marker using pytest?

Use the command: pytest -m <marker_name>. For example, pytest -m slow runs only tests marked as slow.

Why should you register custom markers in pytest's configuration file?

Registering markers in pytest.ini helps avoid warnings and documents the purpose of each marker for better team understanding.

intermediate

Give an example of using markers to separate UI tests from API tests.

Mark UI tests with @pytest.mark.ui and API tests with @pytest.mark.api. Then run them separately using pytest -m ui or pytest -m api.

What does the pytest marker @pytest.mark.smoke indicate?

A The test is part of the smoke test suite

B The test is expected to fail

C The test is slow

D The test is skipped

Markers like 'smoke' label tests as part of a smoke test group to run quick checks.

How do you run tests NOT marked with 'slow' in pytest?

A pytest -m 'not slow'

B pytest --skip slow

C pytest -m slow

D pytest --exclude slow

Use pytest -m 'not slow' to exclude tests marked as slow.

Where do you register custom markers to avoid warnings?

A In the Selenium WebDriver config

B In the test file

C In the Python interpreter

D In pytest.ini or tox.ini

Markers should be registered in pytest.ini or tox.ini to document and avoid warnings.

Which decorator syntax correctly marks a test as 'api'?

A @pytest.api

B @api.mark

C @pytest.mark.api

D @mark.api

The correct syntax is @pytest.mark.api.

What is a benefit of using markers in test automation?

A They speed up test execution by skipping all tests

B They help organize and selectively run tests

C They automatically fix test failures

D They replace the need for assertions

Markers help organize tests and run specific groups as needed.

Explain how markers help in organizing and running tests in pytest.

Think about labeling tests to run only certain groups.
