This methods were moved from xdist (ca03269). Our intention is to keep this code closer to the core, given that it might break easily due to refactorings. Having it in the core might also allow to improve the code by moving some responsibility to the "code" objects (ReprEntry, etc) which are often found in the reports. Finally pytest-xdist and pytest-subtests can use those functions instead of coding it themselves.

The ``pytest`` framework makes it easy to write small tests, yet
scales to support complex functional testing for applications and libraries.
An example of a simple test:
.. code-block:: python
# content of test_sample.py
def inc(x):
return x + 1
def test_answer():
assert inc(3) == 5
To execute it::
$ pytest
============================= test session starts =============================
collected 1 items
test_sample.py F
================================== FAILURES ===================================
_________________________________ test_answer _________________________________
def test_answer():
> assert inc(3) == 5
E assert 4 == 5
E + where 4 = inc(3)
test_sample.py:5: AssertionError
========================== 1 failed in 0.04 seconds ===========================
Due to ``pytest``'s detailed assertion introspection, only plain ``assert`` statements are used. See `getting-started <https://docs.pytest.org/en/latest/getting-started.html#our-first-test-run>`_ for more examples.
Features
--------
- Detailed info on failing `assert statements <https://docs.pytest.org/en/latest/assert.html>`_ (no need to remember ``self.assert*`` names);
- `Auto-discovery
<https://docs.pytest.org/en/latest/goodpractices.html#python-test-discovery>`_
of test modules and functions;
- `Modular fixtures <https://docs.pytest.org/en/latest/fixture.html>`_ for
managing small or parametrized long-lived test resources;
- Can run `unittest <https://docs.pytest.org/en/latest/unittest.html>`_ (or trial),
`nose <https://docs.pytest.org/en/latest/nose.html>`_ test suites out of the box;
- Python 2.7, Python 3.4+, PyPy 2.3, Jython 2.5 (untested);
- Rich plugin architecture, with over 315+ `external plugins <http://plugincompat.herokuapp.com>`_ and thriving community;
