Deselect tests during test collection
-------------------------------------

Tests can individually be deselected during collection by passing the ``--deselect=item`` option.
For example, say ``tests/foobar/test_foobar_01.py`` contains ``test_a`` and ``test_b``.
You can run all of the tests within ``tests/`` *except* for ``tests/foobar/test_foobar_01.py::test_a``
by invoking ``pytest`` with ``--deselect tests/foobar/test_foobar_01.py::test_a``.
``pytest`` allows multiple ``--deselect`` options.

Keeping duplicate paths specified from command line
