generic mechanism for marking python functions.
===============================================
.. contents::
:local:
By using the ``py.test.mark`` helper you can instantiate
decorators that will set named meta data on test functions.
Marking a single function
----------------------------------------------------
You can "mark" a test function with meta data like this::
@py.test.mark.webtest
def test_send_http():
...
This will set a "Marker" instance as a function attribute named "webtest".
You can also specify parametrized meta data like this::
@py.test.mark.webtest(firefox=30)
def test_receive():
...
The named marker can be accessed like this later::
test_receive.webtest.kwargs['firefox'] == 30
In addition to set key-value pairs you can also use positional arguments::
@py.test.mark.webtest("triangular")
def test_receive():
...
and later access it with ``test_receive.webtest.args[0] == 'triangular``.
.. _`scoped-marking`:
Marking classes or modules
----------------------------------------------------
To mark all methods of a class set a ``pytestmark`` attribute like this::
import py
class TestClass:
pytestmark = py.test.mark.webtest
You can re-use the same markers that you would use for decorating
a function - in fact this marker decorator will be applied
to all test methods of the class.
You can also set a module level marker::
import py
pytestmark = py.test.mark.webtest
in which case then the marker decorator will be applied to all functions and
methods defined in the module.
The order in which marker functions are called is this::
per-function (upon import of module already)
per-class
per-module
Later called markers may overwrite previous key-value settings.
Positional arguments are all appended to the same 'args' list
of the Marker object.
Using "-k MARKNAME" to select tests
----------------------------------------------------
You can use the ``-k`` command line option to select
tests::
py.test -k webtest # will only run tests marked as webtest

=========================================
1. Download `pytest_mark.py`_ plugin source code
2. put it somewhere as ``pytest_mark.py`` into your import path
3. a subsequent ``py.test`` run will use your local version
