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 func(x):
|
|
return x + 1
|
|
|
|
def test_answer():
|
|
assert func(3) == 5
|
|
|
|
|
|
To execute it::
|
|
|
|
$ pytest
|
|
======= test session starts ========
|
|
platform linux -- Python 3.4.3, pytest-2.8.5, py-1.4.31, pluggy-0.3.1
|
|
collected 1 items
|
|
|
|
test_sample.py F
|
|
|
|
======= FAILURES ========
|
|
_______ test_answer ________
|
|
|
|
def test_answer():
|
|
> assert func(3) == 5
|
|
E assert 4 == 5
|
|
E + where 4 = func(3)
|
|
|
|
test_sample.py:5: AssertionError
|
|
======= 1 failed in 0.12 seconds ========
|
|
|
|
Due to ``pytest``'s detailed assertion introspection, only plain ``assert`` statements are used. See `getting-started <http://pytest.org/latest/getting-started.html#our-first-test-run>`_ for more examples.
