💡 Hint

Common Mistakes

Using 'fast' or 'skip' instead of 'slow' as the marker name.

Forgetting to add @pytest.mark before the marker.

The marker 'slow' is used to label tests that take longer to run. Here, @pytest.mark.slow marks the test accordingly.

💡 Hint

Common Mistakes

Using a marker name that does not exist in the tests.

Omitting the -m option.

💡 Hint

Common Mistakes

Using space without operator between markers.

Using 'and' instead of 'or' when wanting to run either marker.

To run tests marked 'slow' or 'fast', use 'pytest -m "slow or fast"' or 'pytest -m "slow | fast"'. The pipe '|' and 'or' are correct operators for OR in marker expressions.

Using 'or not' instead of 'and not'.

Not quoting the expression.

The command 'pytest -m "slow and not network"' runs tests marked 'slow' but excludes those also marked 'network'.

💡 Hint

Common Mistakes

Omitting parentheses causing wrong operator precedence.

Using 'and' instead of 'or' inside parentheses.

The command 'pytest -m "(slow or fast) and not network"' runs tests marked 'slow' or 'fast' but excludes those marked 'network'.
