pytest: helps you write better programs
|
|
=======================================
|
|
|
|
|
|
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:
|
|
|
|
.. code-block:: pytest
|
|
|
|
$ pytest
|
|
=========================== test session starts ============================
|
|
platform linux -- Python 3.x.y, pytest-4.x.y, py-1.x.y, pluggy-0.x.y
|
|
cachedir: $PYTHON_PREFIX/.pytest_cache
|
|
rootdir: $REGENDOC_TMPDIR
|
|
collected 1 item
|
|
|
|
test_sample.py F [100%]
|
|
|
|
================================= FAILURES =================================
|
|
_______________________________ test_answer ________________________________
|
|
|
|
def test_answer():
|
|
> assert inc(3) == 5
|
|
E assert 4 == 5
|
|
E + where 4 = inc(3)
|
|
|
|
test_sample.py:6: AssertionError
|
|
========================= 1 failed in 0.12 seconds =========================
|
|
|
|
Due to ``pytest``'s detailed assertion introspection, only plain ``assert`` statements are used.
|
|
See :ref:`Getting Started <getstarted>` for more examples.
