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.
