💡 Hint

Common Mistakes

Using 'tests' as the coverage target instead of the main module.

The --cov option specifies the module to measure coverage for. It should be the main code folder, not the tests folder.

💡 Hint

Common Mistakes

Using 'yes' or 'on' which are not recognized by pytest-cov.

The correct option to enable branch coverage is --cov-branch=true.

Fill both blanks to configure pytest coverage to fail if coverage is below 80% and to show the report in the terminal.

PyTest

pytest --cov=my_module --cov-fail-under=[1] --cov-report=[2] tests/

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Setting fail-under too low or using 'html' instead of 'term' for terminal output.

The --cov-fail-under=80 option makes the test fail if coverage is below 80%. The term report shows coverage in the terminal.

5fill in blank

hard

Fill all four blanks to create a pytest coverage command that measures coverage, generates XML and HTML reports, and fails if coverage is below 90%.

PyTest

pytest --cov=[1] --cov-report=[2] --cov-report=[3] --cov-fail-under=[4] tests/

Drag options to blanks, or click blank then click option'

Common Mistakes

Forgetting to specify the module or mixing up report formats.

This command measures coverage on my_module, outputs XML and HTML reports, and fails if coverage is below 90%.
