With a setuptools installation (otherwise see here) you can type:
easy_install -U py
On Linux systems you may need to execute this as the superuser and on Windows you might need to write down the full path to easy_install.
Now create a file test_sample.py with the following content:
# content of test_sample.py
def func(x):
return x + 1
def test_answer():
assert f(3) == 5
You can now run the test file like this:
py.test test_sample.py
and will see output like this:
=========================== test session starts ============================
python: platform linux2 -- Python 2.6.2
test object 1: test_sample.py
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:6: AssertionError
========================= 1 failed in 0.08 seconds =========================
This output contains Python interpreter information, a list of test objects, a progress report and important details of the failure.
