Requirements

------------

You will need the following prerequisites in order to use pytest-repeat:

- Python 3.7+ or PyPy3

- pytest 4 or newer

Installation

------------

To install pytest-repeat:

.. code-block:: bash

  $ pip install pytest-repeat

Repeating a test

----------------

Use the :code:`--count` command line option to specify how many times you want

your test, or tests, to be run:

.. code-block:: bash

  $ pytest --count=10 test_file.py

Each test collected by pytest will be run :code:`count` times.

If you want to mark a test in your code to be repeated a number of times, you

can use the :code:`@pytest.mark.repeat(count)` decorator:

.. code-block:: python

   import pytest

   @pytest.mark.repeat(3)

   def test_repeat_decorator():

       pass

If you want to override default tests executions order, you can use :code:`--repeat-scope`

command line option with one of the next values: :code:`session`,  :code:`module`, :code:`class` or :code:`function` (default).

It behaves like a scope of the pytest fixture.

:code:`function` (default) scope repeats each test :code:`count` or :code:`repeat` times before executing next test.

:code:`session` scope repeats whole tests session, i.e. all collected tests executed once, then all such tests executed again and etc.

:code:`class` and :code:`module` behaves similar :code:`session` , but repeating set of tests is a tests from class or module, not all collected tests.

Repeating a test until failure

------------------------------

If you are trying to diagnose an intermittent failure, it can be useful to run the same

test over and over again until it fails. You can use pytest's :code:`-x` option in

conjunction with pytest-repeat to force the test runner to stop at the first failure.

For example:

.. code-block:: bash

  $ pytest --count=1000 -x test_file.py

This will attempt to run test_file.py 1000 times, but will stop as soon as a failure

occurs.

UnitTest Style Tests

--------------------

Unfortunately pytest-repeat is not able to work with unittest.TestCase test classes.

These tests will simply always run once, regardless of :code:`--count`, and show a warning.
