Description

Running pytest emits PytestUnknownMarkWarning because tests use the marker @pytest.mark.integration, but the marker is not registered in the pytest configuration.

This results in noisy output during local development and CI runs.

Expected Behavior

• The integration marker should be registered in the pytest configuration.
• pytest should recognize @pytest.mark.integration without emitting warnings.

Actual Behavior

• pytest raises PytestUnknownMarkWarning for tests using @pytest.mark.integration.

Motivation

Unregistered markers create unnecessary warning noise and may hide real warnings or errors in CI logs.

Suggested Fix

Register the marker in pyproject.toml under [tool.pytest.ini_options].

Example:

[tool.pytest.ini_options]
markers = [
    "integration: mark tests as integration tests"
]

Impact

• Removes PytestUnknownMarkWarning
• Cleaner CI and local test output
• Better clarity when real warnings occur
