basic test configuration
|
|
===================================
|
|
|
|
Command line options and configuration file settings
|
|
-----------------------------------------------------------------
|
|
|
|
You can get help on command line options and values in INI-style
|
|
configurations files by using the general help option::
|
|
|
|
py.test -h # prints options _and_ config file settings
|
|
|
|
This will display command line and configuration file settings
|
|
which were registered by installed plugins.
|
|
|
|
How test configuration is read from configuration INI-files
|
|
-------------------------------------------------------------
|
|
|
|
py.test searches for the first matching ini-style configuration file
|
|
in the directories of command line argument and the directories above.
|
|
It looks for file basenames in this order::
|
|
|
|
pytest.ini
|
|
tox.ini
|
|
setup.cfg
|
|
|
|
Searching stops when the first ``[pytest]`` section is found.
|
|
There is no merging of configuration values from multiple files. Example::
|
|
|
|
py.test path/to/testdir
|
|
|
|
will look in the following dirs for a config file::
|
|
|
|
path/to/testdir/pytest.ini
|
|
path/to/testdir/tox.ini
|
|
path/to/testdir/setup.cfg
|
|
path/to/pytest.ini
|
|
path/to/tox.ini
|
|
path/to/setup.cfg
|
|
... # up until root of filesystem
|
|
|
|
If argument is provided to a py.test run, the current working directory
|
|
is used to start the search.

How to change command line options defaults
|
|
------------------------------------------------
|
|
|
|
It can be tedious to type the same series of command line options
|
|
every time you use py.test . For example, if you always want to see
|
|
detailed info on skipped and xfailed tests, as well as have terser "dot"
|
|
progress output, you can write it into a configuration file::
|
|
|
|
# content of pytest.ini
|
|
# (or tox.ini or setup.cfg)
|
|
[pytest]
|
|
addopts = -rsxX -q
|
|
|
|
From now on, running ``py.test`` will add the specified options.
|
|
|
|
builtin configuration file options
|
|
----------------------------------------------
|
|
|
|
.. confval:: minversion
|
|
|
|
specifies a minimal pytest version required for running tests.
|
|
|
|
minversion = 2.1 # will fail if we run with pytest-2.0
|
|
|
|
.. confval:: addopts
|
|
|
|
add the specified ``OPTS`` to the set of command line arguments as if they
|
|
had been specified by the user. Example: if you have this ini file content::
|
|
|
|
[pytest]
|
|
addopts = --maxfail=2 -rf # exit after 2 failures, report fail info
|
|
|
|
issuing ``py.test test_hello.py`` actually means::
|
|
|
|
py.test --maxfail=2 -rf test_hello.py
|
|
|
|
Default is to add no options.
|
|
|
|
.. confval:: norecursedirs
|
|
|
|
Set the directory basename patterns to avoid when recursing
|
|
for test discovery. The individual (fnmatch-style) patterns are
|
|
applied to the basename of a directory to decide if to recurse into it.
|
|
Pattern matching characters::
|
|
|
|
* matches everything
|
|
? matches any single character
|
|
[seq] matches any character in seq
|
|
[!seq] matches any char not in seq
|
|
|
|
Default patterns are ``.* _* CVS {args}``. Setting a ``norecurse``
|
|
replaces the default. Here is an example of how to avoid
|
|
certain directories::
|
|
|
|
# content of setup.cfg
|
|
[pytest]
|
|
norecursedirs = .svn _build tmp*
|
|
|
|
This would tell py.test to not look into typical subversion or
|
|
sphinx-build directories or into any ``tmp`` prefixed directory.
|
|
|
|
.. confval:: python_files
|
|
|
|
One or more Glob-style file patterns determining which python files
|
|
are considered as test modules.
|
|
|
|
.. confval:: python_classes
|
|
|
|
One or more name prefixes determining which test classes
|
|
are considered as test modules.
|
|
|
|
.. confval:: python_functions
|
|
|
|
One or more name prefixes determining which test functions
|
|
and methods are considered as test modules.
|
|
|
|
See :ref:`change naming conventions` for examples.
