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 ===========================
Thanks to pytest's detailed assertion introspection, you can simply use plain assert statements. See getting-started <https://docs.pytest.org/en/stable/getting-started.html#our-first-test-run>_ for more examples.
Detailed info on failing assert statements <https://docs.pytest.org/en/stable/how-to/assert.html>_ (no need to remember self.assert* names)
Auto-discovery <https://docs.pytest.org/en/stable/explanation/goodpractices.html#python-test-discovery>_
of test modules and functions
Modular fixtures <https://docs.pytest.org/en/stable/explanation/fixtures.html>_ for
managing small or parametrized long-lived test resources
Can run unittest <https://docs.pytest.org/en/stable/how-to/unittest.html>_ (or trial)
test suites out of the box
Python 3.10+ or PyPy3
Rich plugin architecture, with over 1300+ external plugins <https://docs.pytest.org/en/latest/reference/plugin_list.html>_ and thriving community
