a5e7b2760d fix issue90 - perform teardown after its actual test function/item. This is implemented by modifying the runtestprotocol to remember "pending" teardowns and call them before the setup of the next item. 2011-11-18 16:01:29 +00:00

d4fe273b2f fix FD leakage during pytest's own test run and add "--lsof" option to tox default test runs.
the leakage came down to a problematic bit of the stdlib logging module: it takes ownerships of stdout/stderr making it hard for pytest to implement clean capturing.  The current work around is to add some extra code in the setup machinery of pytest's own tests which actually closes sub-FDs.

9d92b19ed1 Mention issue #77 in changelog 2011-10-17 22:17:41 +01:00
Floris Bruynooghe
e2201fe3a9 Look up the pytest_assertrepr_compare hook for each test item
Before this was only done at the time the assertion plugin was loaded.
This lead to counter-intuitive behaviour where two subdirectories with
a pytest_assertrepr_compare hook in their conftest.py would not work,
only one would ever be used.

This defers assiging the _pytest.assertion.util._reprcompare function
until the item is loaded (pytest_runtest_setup) so that it can use the
hookrelay of the test item to find the appropriate
pytest_assertrepr_compare hook for the item.

This fixes issue #77.

Use load_module on the import hook to load the rewritten module. This allows the

cache location. It also plays more nicely with parallel py.test processes like
the ones found in xdist.

Changes between 2.1.3 and 2.2.0
----------------------------------------
- fix issue90: introduce eager tearing down of test items so that
teardown function are called earlier.
- add an all-powerful metafunc.parametrize function which allows to
parametrize test function arguments in multiple steps and therefore
from indepdenent plugins and palces.
- add a @pytest.mark.parametrize helper which allows to easily
call a test function with different argument values
- Add examples to the "parametrize" example page, including a quick port
of Test scenarios and the new parametrize function and decorator.
- introduce registration for "pytest.mark.*" helpers via ini-files
or through plugin hooks. Also introduce a "--strict" option which
will treat unregistered markers as errors
allowing to avoid typos and maintain a well described set of markers
for your test suite. See exaples at http://pytest.org/latest/mark.html
and its links.
- issue50: introduce "-m marker" option to select tests based on markers
(this is a stricter and more predictable version of '-k' in that "-m"
only matches complete markers and has more obvious rules for and/or
semantics.
- new feature to help optimizing the speed of your tests:
--durations=N option for displaying N slowest test calls
and setup/teardown methods.
- fix issue87: --pastebin now works with python3
- fix issue89: --pdb with unexpected exceptions in doctest work more sensibly
- fix and cleanup pytest's own test suite to not leak FDs
- fix issue83: link to generated funcarg list
- fix issue74: pyarg module names are now checked against imp.find_module false positives
- fix compatibility with twisted/trial-11.1.0 use cases
Changes between 2.1.2 and 2.1.3
----------------------------------------
- fix issue79: assertion rewriting failed on some comparisons in boolops
- correctly handle zero length arguments (a la pytest '')
- fix issue67 / junitxml now contains correct test durations, thanks ronny
- fix issue75 / skipping test failure on jython
- fix issue77 / Allow assertrepr_compare hook to apply to a subset of tests
Changes between 2.1.1 and 2.1.2
----------------------------------------
- fix assertion rewriting on files with windows newlines on some Python versions
- refine test discovery by package/module name (--pyargs), thanks Florian Mayer
- fix issue69 / assertion rewriting fixed on some boolean operations
- fix issue68 / packages now work with assertion rewriting
- fix issue66: use different assertion rewriting caches when the -O option is passed
- don't try assertion rewriting on Jython, use reinterp
Changes between 2.1.0 and 2.1.1
----------------------------------------------
- fix issue64 / pytest.set_trace now works within pytest_generate_tests hooks
- fix issue60 / fix error conditions involving the creation of __pycache__
- fix issue63 / assertion rewriting on inserts involving strings containing '%'
- fix assertion rewriting on calls with a ** arg
- don't cache rewritten modules if bytecode generation is disabled
- fix assertion rewriting in read-only directories
- fix issue59: provide system-out/err tags for junitxml output
- fix issue61: assertion rewriting on boolean operations with 3 or more operands
- you can now build a man page with "cd doc ; make man"
Changes between 2.0.3 and 2.1.0.DEV
----------------------------------------------
- fix issue53 call nosestyle setup functions with correct ordering
- fix issue58 and issue59: new assertion code fixes
- merge Benjamin's assertionrewrite branch: now assertions
for test modules on python 2.6 and above are done by rewriting
the AST and saving the pyc file before the test module is imported.
see doc/assert.txt for more info.
- fix issue43: improve doctests with better traceback reporting on
unexpected exceptions
- fix issue47: timing output in junitxml for test cases is now correct
- fix issue48: typo in MarkInfo repr leading to exception
- fix issue49: avoid confusing error when initizaliation partially fails
- fix issue44: env/username expansion for junitxml file path
- show releaselevel information in test runs for pypy
- reworked doc pages for better navigation and PDF generation
- report KeyboardInterrupt even if interrupted during session startup
- fix issue 35 - provide PDF doc version and download link from index page

"""View base class.
If C is a subclass of View, then C(x) creates a proxy object around
the object x. The actual class of the proxy is not C in general,
but a *subclass* of C determined by the rules below. To avoid confusion
we call view class the class of the proxy (a subclass of C, so of View)
and object class the class of x.
Attributes and methods not found in the proxy are automatically read on x.
Other operations like setting attributes are performed on the proxy, as
determined by its view class. The object x is available from the proxy
as its __obj__ attribute.
The view class selection is determined by the __view__ tuples and the
optional __viewkey__ method. By default, the selected view class is the
most specific subclass of C whose __view__ mentions the class of x.
If no such subclass is found, the search proceeds with the parent
object classes. For example, C(True) will first look for a subclass
of C with __view__ = (..., bool, ...) and only if it doesn't find any
look for one with __view__ = (..., int, ...), and then ..., object,...
If everything fails the class C itself is considered to be the default.
Alternatively, the view class selection can be driven by another aspect
of the object x, instead of the class of x, by overriding __viewkey__.

py.test 2.1.0: perfected assertions and bug fixes
===========================================================================
Welcome to the relase of pytest-2.1, a mature testing tool for Python,
supporting CPython 2.4-3.2, Jython and latest PyPy interpreters. See
the improved extensive docs (now also as PDF!) with tested examples here:
http://pytest.org/
The single biggest news about this release are **perfected assertions**
courtesy of Benjamin Peterson. You can now safely use ``assert``
statements in test modules without having to worry about side effects
or python optimization ("-OO") options. This is achieved by rewriting
assert statements in test modules upon import, using a PEP302 hook.
See http://pytest.org/assert.html#advanced-assertion-introspection for
detailed information. The work has been partly sponsored by my company,
merlinux GmbH.
For further details on bug fixes and smaller enhancements see below.
If you want to install or upgrade pytest, just type one of::
pip install -U pytest # or
easy_install -U pytest
best,
holger krekel / http://merlinux.eu
Changes between 2.0.3 and 2.1.0
----------------------------------------------
- fix issue53 call nosestyle setup functions with correct ordering
- fix issue58 and issue59: new assertion code fixes
- merge Benjamin's assertionrewrite branch: now assertions
for test modules on python 2.6 and above are done by rewriting
the AST and saving the pyc file before the test module is imported.
see doc/assert.txt for more info.
- fix issue43: improve doctests with better traceback reporting on
unexpected exceptions
- fix issue47: timing output in junitxml for test cases is now correct
- fix issue48: typo in MarkInfo repr leading to exception
- fix issue49: avoid confusing error when initizaliation partially fails
- fix issue44: env/username expansion for junitxml file path
- show releaselevel information in test runs for pypy
- reworked doc pages for better navigation and PDF generation
- report KeyboardInterrupt even if interrupted during session startup
- fix issue 35 - provide PDF doc version and download link from index page

py.test 2.1.1: assertion fixes and improved junitxml output
===========================================================================
pytest-2.1.1 is a backward compatible maintenance release of the
popular py.test testing tool. See extensive docs with examples here:
http://pytest.org/
Most bug fixes address remaining issues with the perfected assertions
introduced with 2.1.0 - many thanks to the bug reporters and to Benjamin
Peterson for helping to fix them. Also, junitxml output now produces
system-out/err tags which lead to better displays of tracebacks with Jenkins.
Also a quick note to package maintainers and others interested: there now
is a "pytest" man page which can be generated with "make man" in doc/.
If you want to install or upgrade pytest, just type one of::
pip install -U pytest # or
easy_install -U pytest
best,
holger krekel / http://merlinux.eu
Changes between 2.1.0 and 2.1.1
----------------------------------------------
- fix issue64 / pytest.set_trace now works within pytest_generate_tests hooks
- fix issue60 / fix error conditions involving the creation of __pycache__
- fix issue63 / assertion rewriting on inserts involving strings containing '%'
- fix assertion rewriting on calls with a ** arg
- don't cache rewritten modules if bytecode generation is disabled
- fix assertion rewriting in read-only directories
- fix issue59: provide system-out/err tags for junitxml output
- fix issue61: assertion rewriting on boolean operations with 3 or more operands
- you can now build a man page with "cd doc ; make man"

py.test 2.1.2: bug fixes and fixes for jython

pytest-2.1.2 is a minor backward compatible maintenance release of the
popular py.test testing tool. pytest is commonly used for unit,
functional- and integration testing. See extensive docs with examples
here:
http://pytest.org/
Most bug fixes address remaining issues with the perfected assertions
introduced in the 2.1 series - many thanks to the bug reporters and to Benjamin
Peterson for helping to fix them. pytest should also work better with
Jython-2.5.1 (and Jython trunk).

- fix assertion rewriting on files with windows newlines on some Python versions
- refine test discovery by package/module name (--pyargs), thanks Florian Mayer
- fix issue69 / assertion rewriting fixed on some boolean operations
- fix issue68 / packages now work with assertion rewriting
- fix issue66: use different assertion rewriting caches when the -O option is passed

py.test 2.2.0: test marking++, parametrization++ and duration profiling
===========================================================================
pytest-2.2.0 is a test-suite compatible release of the popular
py.test testing tool. Plugins might need upgrades. It comes
with these improvements:
* easier and more powerful parametrization of tests:
- new @pytest.mark.parametrize decorator to run tests with different arguments
- new metafunc.parametrize() API for parametrizing arguments independently
- see examples at http://pytest.org/latest/example/parametrize.html
- NOTE that parametrize() related APIs are still a bit experimental
and might change in future releases.
* improved handling of test markers and refined marking mechanism:
- "-m markexpr" option for selecting tests according to their mark
- a new "markers" ini-variable for registering test markers for your project
- the new "--strict" bails out with an error if using unregistered markers.
- see examples at http://pytest.org/latest/example/markers.html
* duration profiling: new "--duration=N" option showing the N slowest test
execution or setup/teardown calls. This is most useful if you want to
find out where your slowest test code is.
* also 2.2.0 performs more eager calling of teardown/finalizers functions
resulting in better and more accurate reporting when they fail
Besides there is the usual set of bug fixes along with a cleanup of
pytest's own test suite allowing it to run on a wider range of environments.
For general information, see extensive docs with examples here:

notes on incompatibility
------------------------------
While test suites should work unchanged you might need to upgrade plugins:
* You need a new version of the pytest-xdist plugin (1.7) for distributing
test runs.
* Other plugins might need an upgrade if they implement
the ``pytest_runtest_logreport`` hook which now is called unconditionally
for the setup/teardown fixture phases of a test. You may choose to
ignore setup/teardown failures by inserting "if rep.when != 'call': return"
or something similar. Note that most code probably "just" works because
the hook was already called for failing setup/teardown phases of a test
so a plugin should have been ready to grok such reports already.
Changes between 2.1.3 and 2.2.0
----------------------------------------
- fix issue90: introduce eager tearing down of test items so that
teardown function are called earlier.
- add an all-powerful metafunc.parametrize function which allows to
parametrize test function arguments in multiple steps and therefore
from indepdenent plugins and palces.
- add a @pytest.mark.parametrize helper which allows to easily
call a test function with different argument values
- Add examples to the "parametrize" example page, including a quick port
of Test scenarios and the new parametrize function and decorator.
- introduce registration for "pytest.mark.*" helpers via ini-files
or through plugin hooks. Also introduce a "--strict" option which
will treat unregistered markers as errors
allowing to avoid typos and maintain a well described set of markers
for your test suite. See exaples at http://pytest.org/latest/mark.html
and its links.
- issue50: introduce "-m marker" option to select tests based on markers
(this is a stricter and more predictable version of '-k' in that "-m"
only matches complete markers and has more obvious rules for and/or
semantics.
- new feature to help optimizing the speed of your tests:
--durations=N option for displaying N slowest test calls
and setup/teardown methods.
- fix issue87: --pastebin now works with python3
- fix issue89: --pdb with unexpected exceptions in doctest work more sensibly
- fix and cleanup pytest's own test suite to not leak FDs
- fix issue83: link to generated funcarg list
- fix issue74: pyarg module names are now checked against imp.find_module false positives
- fix compatibility with twisted/trial-11.1.0 use cases

.. _`assert introspection`:
Advanced assertion introspection
----------------------------------
.. versionadded:: 2.1
Reporting details about a failing assertion is achieved either by rewriting
assert statements before they are run or re-evaluating the assert expression and
recording the intermediate values. Which technique is used depends on the
location of the assert, py.test's configuration, and Python version being used
to run py.test. Note that for assert statements with a manually provided
message, i.e. ``assert expr, message``, no assertion introspection takes place
and the manually provided message will be rendered in tracebacks.
By default, if the Python version is greater than or equal to 2.6, py.test
rewrites assert statements in test modules. Rewritten assert statements put
introspection information into the assertion failure message. py.test only
rewrites test modules directly discovered by its test collection process, so
asserts in supporting modules which are not themselves test modules will not be
rewritten.
.. note::
py.test rewrites test modules on import. It does this by using an import hook
to write a new pyc files. Most of the time this works transparently. However,
if you are messing with import yourself, the import hook may interfere. If
this is the case, simply use ``--assert=reinterp`` or
``--assert=plain``. Additionally, rewriting will fail silently if it cannot
write new pycs, i.e. in a read-only filesystem or a zipfile.
If an assert statement has not been rewritten or the Python version is less than
2.6, py.test falls back on assert reinterpretation. In assert reinterpretation,
py.test walks the frame of the function containing the assert statement to
discover sub-expression results of the failing assert statement. You can force
py.test to always use assertion reinterpretation by passing the
``--assert=reinterp`` option.
Assert reinterpretation has a caveat not present with assert rewriting: If
evaluating the assert expression has side effects you may get a warning that the
intermediate values could not be determined safely. A common example of this
issue is an assertion which reads from a file::
assert f.read() != '...'
If this assertion fails then the re-evaluation will probably succeed!
This is because ``f.read()`` will return an empty string when it is
called the second time during the re-evaluation. However, it is
easy to rewrite the assertion and avoid any trouble::
content = f.read()
assert content != '...'
All assert introspection can be turned off by passing ``--assert=plain``.
For further information, Benjamin Peterson wrote up `Behind the scenes of py.test's new assertion rewriting <http://pybites.blogspot.com/2011/07/behind-scenes-of-pytests-new-assertion.html>`_.
.. versionadded:: 2.1
Add assert rewriting as an alternate introspection technique.

def test_send_http():
pass # perform some webtest test for your app
def test_something_quick():

================== 1 passed, 1 deselected in 0.01 seconds ==================
Registering markers
-------------------------------------
.. versionadded:: 2.2
.. ini-syntax for custom markers:
Registering markers for your test suite is simple::
# content of pytest.ini
[pytest]
markers =
webtest: mark a test as a webtest.
You can ask which markers exist for your test suite - the list includes our just defined ``webtest`` markers::
$ py.test --markers
@pytest.mark.webtest: mark a test as a webtest.
@pytest.mark.skipif(*conditions): skip the given test function if evaluation of all conditions has a True value. Evaluation happens within the module global context. Example: skipif('sys.platform == "win32"') skips the test if we are on the win32 platform.
@pytest.mark.xfail(*conditions, reason=None, run=True): mark the the test function as an expected failure. Optionally specify a reason and run=False if you don't even want to execute the test function. Any positional condition strings will be evaluated (like with skipif) and if one is False the marker will not be applied.
@pytest.mark.parametrize(argnames, argvalues): call a test function multiple times passing in multiple different argument value sets. Example: @parametrize('arg1', [1,2]) would lead to two calls of the decorated test function, one with arg1=1 and another with arg1=2.
@pytest.mark.tryfirst: mark a hook implementation function such that the plugin machinery will try to call it first/as early as possible.
@pytest.mark.trylast: mark a hook implementation function such that the plugin machinery will try to call it last/as late as possible.
For an example on how to add and work with markers from a plugin, see
:ref:`adding a custom marker from a plugin`.
.. note::
It is recommended to explicitely register markers so that:
* there is one place in your test suite defining your markers
* asking for existing markers via ``py.test --markers`` gives good output
* typos in function markers are treated as an error if you use
the ``--strict`` option. Later versions of py.test are probably
going to treat non-registered markers as an error.
.. _`scoped-marking`:
Marking whole classes or modules
----------------------------------------------------
If you are programming with Python2.6 you may use ``pytest.mark`` decorators
with classes to apply markers to all of its test methods::
# content of test_mark_classlevel.py
import pytest
@pytest.mark.webtest
class TestClass:
def test_startup(self):
pass
def test_startup_and_more(self):
pass
This is equivalent to directly applying the decorator to the
two test functions.
To remain backward-compatible with Python2.4 you can also set a
``pytestmark`` attribute on a TestClass like this::
import pytest
class TestClass:
pytestmark = pytest.mark.webtest
or if you need to use multiple markers you can use a list::
import pytest
class TestClass:
pytestmark = [pytest.mark.webtest, pytest.mark.slowtest]
You can also set a module level marker::
import pytest
pytestmark = pytest.mark.webtest
in which case it will be applied to all functions and
methods defined in the module.
Using ``-k TEXT`` to select tests
----------------------------------------------------
You can use the ``-k`` command line option to only run tests with names that match the given argument::
$ py.test -k send_http # running with the above defined examples
=========================== test session starts ============================

.. _`adding a custom marker from a plugin`:
custom marker and command line option to control test runs
----------------------------------------------------------
Plugins can provide custom markers and implement specific behaviour
based on it. This is a self-contained example which adds a command
line option and a parametrized test function marker to run tests
specifies via named environments::
# content of conftest.py
import pytest
def pytest_addoption(parser):
parser.addoption("-E", dest="env", action="store", metavar="NAME",
help="only run tests matching the environment NAME.")
def pytest_configure(config):
# register an additional marker
config.addinivalue_line("markers",
"env(name): mark test to run only on named environment")
def pytest_runtest_setup(item):
if not isinstance(item, item.Function):
return
if hasattr(item.obj, 'env'):
envmarker = getattr(item.obj, 'env')
envname = envmarker.args[0]
if envname != item.config.option.env:
pytest.skip("test requires env %r" % envname)
A test file using this local plugin::
# content of test_someenv.py
import pytest
@pytest.mark.env("stage1")
def test_basic_db_operation():
pass
and an example invocations specifying a different environment than what
the test needs::
$ py.test -E stage2

========================= 5 passed in 0.04 seconds =========================
The ``--markers`` option always gives you a list of available markers::
$ py.test --markers
@pytest.mark.webtest: mark a test as a webtest.
@pytest.mark.env(name): mark test to run only on named environment
@pytest.mark.skipif(*conditions): skip the given test function if evaluation of all conditions has a True value. Evaluation happens within the module global context. Example: skipif('sys.platform == "win32"') skips the test if we are on the win32 platform.
@pytest.mark.xfail(*conditions, reason=None, run=True): mark the the test function as an expected failure. Optionally specify a reason and run=False if you don't even want to execute the test function. Any positional condition strings will be evaluated (like with skipif) and if one is False the marker will not be applied.

``py.test`` still uses many metaprogramming techniques and
reading its source is thus likely not something for Python beginners.
A second "magic" issue arguably the assert statement re-intepreation:
When an ``assert`` statement fails, py.test re-interprets the expression
to show intermediate values if a test fails. If your expression
has side effects (better to avoid them anyway!) the intermediate values
may not be the same, obfuscating the initial error (this is also
explained at the command line if it happens).
``py.test --no-assert`` turns off assert re-interpretation.
A second "magic" issue arguably the assert statement debugging feature. When
loading test modules py.test rewrites the source code of assert statements. When
a rewritten assert statement fails, its error message has more information than
the original. py.test also has a second assert debugging technique. When an
``assert`` statement that was missed by the rewriter fails, py.test
re-interprets the expression to show intermediate values if a test fails. This
second technique suffers from caveat that the rewriting does not: If your
expression has side effects (better to avoid them anyway!) the intermediate
values may not be the same, confusing the reinterpreter and obfuscating the
initial error (this is also explained at the command line if it happens).
You can turn off all assertion debugging with ``py.test --assertmode=off``.

You can simply use the ``assert`` statement for asserting test
expectations. pytest's :ref:`assert introspection` will intelligently
report intermediate values of the assert expression freeing
you from the need to learn the many names of `JUnit legacy methods`_.
However, there remains one caveat to using simple asserts: your
assertion expression should better be side-effect free. Because
after an assertion failed py.test will re-evaluate the expression
in order to present intermediate values. You will get a nice warning
and you can easily fix it: compute the value ahead of the assert and
then do the assertion. Or maybe just use the assert "explicit message"

.. _mark:
mark test functions with attributes
Marking test functions with attributes
=================================================================
.. currentmodule:: _pytest.mark
By using the ``pytest.mark`` helper you can instantiate
decorators that will set named metadata on test functions.
By using the ``pytest.mark`` helper you can easily set
metadata on your test functions. There are
some builtin markers, for example:
Marking a single function
----------------------------------------------------
* :ref:`skipif <skipif>` - skip a test function if a certain condition is met
* :ref:`xfail <xfail>` - produce an "expected failure" outcome if a certain
condition is met
* :ref:`parametrize <parametrizemark>` to perform multiple calls
to the same test function.
You can "mark" a test function with metadata like this::
It's easy to create custom markers or to apply markers
to whole test classes or modules. See :ref:`mark examples` for examples
which also serve as documentation.
import pytest
@pytest.mark.webtest
def test_send_http():
...
This will set the function attribute ``webtest`` to a :py:class:`MarkInfo`
instance. You can also specify parametrized metadata like this::
# content of test_mark.py
import pytest
@pytest.mark.webtest(firefox=30)
def test_receive():
pass
@pytest.mark.webtest("functional", firefox=30)
def test_run_and_look():
pass
and access it from other places like this::
test_receive.webtest.kwargs['firefox'] == 30
test_run_and_look.webtest.args[0] == "functional"
.. _`scoped-marking`:
Marking whole classes or modules
----------------------------------------------------
If you are programming with Python2.6 you may use ``pytest.mark`` decorators
with classes to apply markers to all of its test methods::
# content of test_mark_classlevel.py
import pytest
@pytest.mark.webtest
class TestClass:
def test_startup(self):
pass
def test_startup_and_more(self):
pass
This is equivalent to directly applying the decorator to the
two test functions.
To remain compatible with Python2.5 you can also set a
``pytestmark`` attribute on a TestClass like this::
import pytest
class TestClass:
pytestmark = pytest.mark.webtest
or if you need to use multiple markers you can use a list::
import pytest
class TestClass:
pytestmark = [pytest.mark.webtest, pytest.mark.slowtest]
You can also set a module level marker::
import pytest
pytestmark = pytest.mark.webtest
in which case it will be applied to all functions and
methods defined in the module.
Using ``-k TEXT`` to select tests
