Hooks
-----


.. currentmodule:: _pytest.hookspec

Reference to all hooks which can be implemented by :ref:`conftest.py files <localplugin>` and :ref:`plugins <plugins>`.

Bootstrapping hooks
~~~~~~~~~~~~~~~~~~~

Bootstrapping hooks called for plugins registered early enough (internal and setuptools plugins).

.. autofunction:: pytest_load_initial_conftests
.. autofunction:: pytest_cmdline_preparse
.. autofunction:: pytest_cmdline_parse
.. autofunction:: pytest_cmdline_main

Initialization hooks
~~~~~~~~~~~~~~~~~~~~

Initialization hooks called for plugins and ``conftest.py`` files.

.. autofunction:: pytest_addoption
.. autofunction:: pytest_configure
.. autofunction:: pytest_unconfigure

Test running hooks
~~~~~~~~~~~~~~~~~~

All runtest related hooks receive a :py:class:`pytest.Item <_pytest.main.Item>` object.

.. autofunction:: pytest_runtestloop
.. autofunction:: pytest_runtest_protocol
.. autofunction:: pytest_runtest_logstart
.. autofunction:: pytest_runtest_logfinish
.. autofunction:: pytest_runtest_setup
.. autofunction:: pytest_runtest_call
.. autofunction:: pytest_runtest_teardown
.. autofunction:: pytest_runtest_makereport

For deeper understanding you may look at the default implementation of
these hooks in :py:mod:`_pytest.runner` and maybe also
in :py:mod:`_pytest.pdb` which interacts with :py:mod:`_pytest.capture`
and its input/output capturing in order to immediately drop
into interactive debugging when a test failure occurs.

The :py:mod:`_pytest.terminal` reported specifically uses
the reporting hook to print information about a test run.

Collection hooks
~~~~~~~~~~~~~~~~

``pytest`` calls the following hooks for collecting files and directories:

.. autofunction:: pytest_collection
.. autofunction:: pytest_ignore_collect
.. autofunction:: pytest_collect_directory
.. autofunction:: pytest_collect_file

For influencing the collection of objects in Python modules
you can use the following hook:

.. autofunction:: pytest_pycollect_makeitem
.. autofunction:: pytest_generate_tests
.. autofunction:: pytest_make_parametrize_id

After collection is complete, you can modify the order of
items, delete or otherwise amend the test items:

.. autofunction:: pytest_collection_modifyitems

Reporting hooks
~~~~~~~~~~~~~~~

Session related reporting hooks:

.. autofunction:: pytest_collectstart
.. autofunction:: pytest_itemcollected
.. autofunction:: pytest_collectreport
.. autofunction:: pytest_deselected
.. autofunction:: pytest_report_header
.. autofunction:: pytest_report_collectionfinish
.. autofunction:: pytest_report_teststatus
.. autofunction:: pytest_terminal_summary
.. autofunction:: pytest_fixture_setup
.. autofunction:: pytest_fixture_post_finalizer

And here is the central hook for reporting about
test execution:

.. autofunction:: pytest_runtest_logreport

You can also use this hook to customize assertion representation for some
types:

.. autofunction:: pytest_assertrepr_compare


Debugging/Interaction hooks
~~~~~~~~~~~~~~~~~~~~~~~~~~~

There are few hooks which can be used for special
reporting or interaction with exceptions:

.. autofunction:: pytest_internalerror
.. autofunction:: pytest_keyboard_interrupt
.. autofunction:: pytest_exception_interact
.. autofunction:: pytest_enter_pdb
