Unit Testing/Pytest/View Test Coverage

Install Coverage using either:

• pip install coverage
• pip3 install coverage

Run tests using Coverage to monitor test coverage:

coverage run -m pytest

Generate a coverage report:

coverage report

Generate a coverage report with line numbers:

coverage report -m

Generate a coverage HTML report:

coverage html

Look for an htmlcov folder and open index.html in your browser. In the report, select multiply.py to view test coverage of the multiply function.

A .coveragec file is used to customize the location and content of the Coverage HTML report. For example, the following would omit any Python library files in the /.local folder, exclude pragma: no cover lines, and rename the htmlcov folder to coverage_report. See Coverage documentation for more information.

[run]
omit =
    */.local/*

[report]
exclude_lines =
    pragma: no cover

[html]
directory = coverage_report
