|
||||
|
||||
|
||||
Basic usage
|
||||
==================
|
||||
|
||||
We assume you have done an :ref:`install` like this::
|
||||
|
||||
easy_install -U pytest # or
|
||||
pip install -U pytest
|
||||
|
||||
Ensure that this installed the ``py.test`` script::
|
||||
|
||||
py.test --version
|
||||
|
||||
|
||||
Writing a first test
|
||||
------------------------------
|
||||
|
||||
Let's create a small file with the following content::
|
||||
|
||||
# content of test_sample.py
|
||||
def func(x):
|
||||
return x + 1
|
||||
def test_answer():
|
||||
assert func(3) == 5
|
||||
|
||||
That's it. Now you can already execute the test function::
|
||||
|
||||
$ py.test test_sample.py
|
||||
=========================== test session starts ============================

||||

================================= FAILURES =================================

|

|
||||
def test_answer():
|
||||
> assert func(3) == 5
|
||||
E assert 4 == 5
|
||||
E + where 4 = func(3)
|
||||
|
||||
test_sample.py:4: AssertionError
|
||||
========================= 1 failed in 0.02 seconds =========================
|
||||
|
||||
We got a failure because our little ``func(3)`` call did not return ``5``.
|
||||
A few notes on this little test invocation:
|
||||
|
||||
* ``test_answer`` was identified as a test function because of the
|
||||
``test_`` prefix,
|
||||
|
||||
* we conveniently used the standard `assert statement`_ and the failure
|
||||
report shows us the intermediate values.

Using the interactive command line

Getting help on version, option names, environment vars
|

|

Stopping after the first (or N) failures
|
||||
---------------------------------------------------
|
||||
|
||||
To stop the testing process after the first (N) failures::
|
||||
|
||||
py.test -x # stop after first failure
|
||||
py.test -maxfail=2 # stop after two failures
|
||||
|
||||
Modifying Python traceback printing
|
||||
----------------------------------------------
|
||||
|
||||
Examples for modifying traceback printing::
|
||||
|
||||
py.test --showlocals # show local variables in tracebacks
|
||||
py.test -l # show local variables (shortcut)
|
||||
|
||||
py.test --tb=long # the default informative traceback formatting
|
||||
py.test --tb=native # the Python standard library formatting
|
||||
py.test --tb=short # a shorter traceback format
|
||||
py.test --tb=line # only one line per failure
|
||||
|
||||
Dropping to PDB (Python Debugger) on failures
|
||||
----------------------------------------------
|
||||
|
||||
.. _PDB: http://docs.python.org/library/pdb.html
|
||||
|
||||
Python comes with a builtin Python debugger called PDB_. ``py.test``
|
||||
allows to drop into the PDB prompt via a command line option::
|
||||
|
||||
py.test --pdb
|
||||
|
||||
This will invoke the Python debugger on every failure. Often you might
|
||||
only want to do this for the first failing test to understand a certain
|
||||
failure situation::
|
||||
|
||||
py.test -x --pdb # drop to PDB on first failure, then end test session
|
||||
py.test --pdb --maxfail=3 # drop to PDB for the first three failures
|
||||
|
||||
|
||||
Setting a breakpoint / aka ``set_trace()``
|
||||
----------------------------------------------------
|
||||
|
||||
If you want to set a breakpoint and enter the ``pdb.set_trace()`` you
|
||||
can use a helper::
|
||||
|
||||
def test_function():
|
||||
...
|
||||
py.test.set_trace() # invoke PDB debugger and tracing
|
||||
|
||||
.. versionadded: 2.0.0
|
||||
|
||||
In previous versions you could only enter PDB tracing if
|
||||
you :ref:`disable capturing`.
|
||||
|
||||
creating JUnitXML format files
|
||||
----------------------------------------------------
|
||||
|
||||
To create result files which can be read by Hudson_ or other Continous
|
||||
integration servers, use this invocation::
|
||||
|
||||
py.test --junitxml=path
|
||||
|
||||
to create an XML file at ``path``.
|
||||
|
||||
creating resultlog format files
|
||||
----------------------------------------------------
|
||||
|
||||
To create plain-text machine-readable result files you can issue::
|
||||
|
||||
py.test --resultlog=path
|
||||
|
||||
and look at the content at the ``path`` location. Such files are used e.g.
|
||||
by the `PyPy-test`_ web page to show test results over several revisions.

||||

|
||||
-----------------------------------------------------
|
||||
|
||||
**Creating a URL for each test failure**::
|
||||
|
||||
py.test --pastebin=failed
|
||||
|
||||
This will submit test run information to a remote Paste service and
|
||||
provide a URL for each failure. You may select tests as usual or add
|
||||
for example ``-x`` if you only want to send one particular failure.
|
||||
|
||||
**Creating a URL for a whole test session log**::
|
||||
|
||||
py.test --pastebin=all
|
||||
|
||||
Currently only pasting to the http://paste.pocoo.org service is implemented.

.. _`retrieved by hooks as item keywords`:
|
||||
|

control skipping of tests according to command line option
|
||||
--------------------------------------------------------------
|
||||
|
||||
Here is a ``conftest.py`` file adding a ``--runslow`` command
|
||||
line option to control skipping of ``slow`` marked tests::
|
||||
|
||||
# content of conftest.py
|
||||
|
||||
import py
|

def pytest_addoption(parser):

if 'slow' in item.keywords and not item.config.getvalue("runslow"):

mysetup pattern: application specific test fixtures
|
||||
==========================================================
|
||||
|
||||
Here is a basic useful step-by-step example for managing and interacting
|
||||
with application specific test setup. The goal is to have one place
|
||||
where we have the glue and test support code for bootstrapping and
|
||||
configuring application objects and allow test modules and test
|
||||
functions to stay ignorant of involved details.
|
||||
|
||||
step1: implementing the test/app-specific ``mysetup`` pattern
|
||||
-------------------------------------------------------------
|
||||
|
||||
Let's write a simple test function using a ``mysetup`` funcarg::
|
||||
|
||||
# content of test_sample.py
|
||||
def test_answer(mysetup):
|
||||
app = mysetup.myapp()
|
||||
answer = app.question()
|
||||
assert answer == 42
|
||||
|
||||
To run this test py.test needs to find and call a factory to
|
||||
obtain the required ``mysetup`` function argument. To make
|
||||
an according factory findable we write down a specifically named factory
|
||||
method in a :ref:`local plugin`::
|
||||
|
||||
# content of conftest.py
|
||||
from myapp import MyApp
|
||||
|
||||
def pytest_funcarg__mysetup(request): # "mysetup" factory function
|
||||
return MySetup()
|
||||
|
||||
class MySetup: # instances of this are seen by test functions
|
||||
def myapp(self):
|
||||
return MyApp()
|
||||
|
||||
To run the example we stub out a a simple ``MyApp`` application object::
|
||||
|
||||
# content of myapp.py
|
||||
class MyApp:
|
||||
def question(self):
|
||||
return 6 * 9
|
||||
|
||||
You can now run the test::
|
||||
|
||||
$ py.test test_sample.py
|
||||
=========================== test session starts ============================
|
||||
platform linux2 -- Python 2.6.5 -- pytest-2.0.0dev0

||||

||||
================================= FAILURES =================================

||||
_______________________________ test_answer ________________________________
|
||||
|
||||
mysetup = <conftest.MySetup instance at 0x1a09f38>
|
||||
|
||||
def test_answer(mysetup):
|
||||
app = mysetup.myapp()
|
||||
answer = app.question()
|
||||
> assert answer == 42
|
||||
E assert 54 == 42
|
||||
|
||||
test_sample.py:4: AssertionError
|
||||
========================= 1 failed in 0.02 seconds =========================
|
||||
|
||||
This means that our ``mysetup`` object was successfully instantiated
|
||||
and ``mysetup.app()`` returned an initialized ``MyApp`` instance.
|
||||
We can ask it about the question and if you are confused as to what
|
||||
the concrete question or answers actually mean, please see here_.

|
||||
|
||||
step 2: checking a command line option and skipping tests
|
||||
-----------------------------------------------------------
|
||||
|
||||
To add a command line option we update the ``conftest.py`` of
|
||||
the previous example to add a command line option
|
||||
and to offer a new mysetup method::
|
||||
|
||||
# content of ./conftest.py
|
||||
import py
|
||||
from myapp import MyApp
|
||||
|
||||
def pytest_funcarg__mysetup(request): # "mysetup" factory function
|
||||
return MySetup(request)
|
||||
|
||||
def pytest_addoption(parser):
|
||||
parser.addoption("--ssh", action="store", default=None,
|
||||
help="specify ssh host to run tests with")
|
||||
|
||||
|
||||
class MySetup:
|
||||
def __init__(self, request):
|
||||
self.config = request.config
|
||||
|
||||
def myapp(self):
|
||||
return MyApp()
|
||||
|
||||
def getsshconnection(self):
|
||||
host = self.config.option.ssh
|
||||
if host is None:
|
||||
py.test.skip("specify ssh host with --ssh")
|
||||
return execnet.SshGateway(host)
|
||||
|
||||
|
||||
Now any test function can use the ``mysetup.getsshconnection()`` method
|
||||
like this::
|
||||
|
||||
# content of test_ssh.py
|
||||
class TestClass:
|
||||
def test_function(self, mysetup):
|
||||
conn = mysetup.getsshconnection()
|
||||
# work with conn
|
||||
|
||||
Running it yields::
|
||||
|
||||
$ py.test test_ssh.py -rs

||||

======================== 1 skipped in 0.02 seconds =========================
|
||||
|
||||
If you specify a command line option like ``py.test --ssh=python.org`` the test will execute as expected.
|
||||
|
||||
Note that neither the ``TestClass`` nor the ``test_function`` need to
|
||||
know anything about how to setup the test state. It is handled separately
|
||||
in your "test setup glue" code in the ``conftest.py`` file. It is easy
|
||||
to extend the ``mysetup`` object for further needs in the test code - and for use by any other test functions in the files and directories below the ``conftest.py`` file.

python mytest --pastebin=all
