testing

Structure unit tests for Canvas plugins by creating a mirrored test directory under tests/. This layout mirrors your plugin's source directories to ensure predictable test placement and straightforward module mapping.

Verify mocks strictly in pytest using the mock_calls attribute. This approach ensures that all interactions with mocked protocol, API, and helper modules are validated accurately without missing expected method calls.

Yes, you need conftest fixtures to test Canvas plugins effectively. The pytest-based workflow uses conftest fixtures to provide a complete pattern for setting up test data, configuring mocks, and handling verification across your modules.

Exclude test code from coverage reports in pytest by applying coverage discipline. The framework automatically excludes test code from coverage reports while guiding teams to reach and maintain target coverage across protocol and API modules.

The best way to enforce test coverage for Canvas plugin development is integrating a pytest-based workflow with your CI. This enforces target coverage across protocol, API, and helper modules while reducing debugging time.
