This is unfortunately a dependency on `py.path` which cannot be moved to an external plugins or eased in any way, so has to be deprecated in order for pytest to be able to eventually remove the dependency on `py`.

Deprecations and Removals
|
|
=========================
|
|
|
|
This page lists all pytest features that are currently deprecated or have been removed in past major releases.
|
|
The objective is to give users a clear rationale why a certain feature has been removed, and what alternatives
|
|
should be used instead.

Deprecated Features
|
|
-------------------
|
|
|
|
Below is a complete list of all pytest features which are considered deprecated. Using those features will issue
|
|
:class:`PytestWarning` or subclasses, which can be filtered using :ref:`standard warning filters <warnings>`.
|
|
|
|
.. _node-ctor-fspath-deprecation:
|
|
|
|
``fspath`` argument for Node constructors replaced with ``pathlib.Path``
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. deprecated:: 7.0
|
|
|
|
In order to support the transition from ``py.path.local`` to :mod:`pathlib`,
|
|
the ``fspath`` argument to :class:`~_pytest.nodes.Node` constructors like
|
|
:func:`pytest.Function.from_parent()` and :func:`pytest.Class.from_parent()`
|
|
is now deprecated.
|
|
|
|
Plugins which construct nodes should pass the ``path`` argument, of type
|
|
:class:`pathlib.Path`, instead of the ``fspath`` argument.
|
|
|
|
Plugins which implement custom items and collectors are encouraged to replace
|
|
``py.path.local`` ``fspath`` parameters with ``pathlib.Path`` parameters, and
|
|
drop any other usage of the ``py`` library if possible.
|
|
|
|
|
|
.. _legacy-path-hooks-deprecated:
|
|
|
|
``py.path.local`` arguments for hooks replaced with ``pathlib.Path``
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. deprecated:: 7.0
|
|
|
|
In order to support the transition from ``py.path.local`` to :mod:`pathlib`, the following hooks now receive additional arguments:
|
|
|
|
* :func:`pytest_ignore_collect(fspath: pathlib.Path) <_pytest.hookspec.pytest_ignore_collect>` instead of ``path``
|
|
* :func:`pytest_collect_file(fspath: pathlib.Path) <_pytest.hookspec.pytest_collect_file>` instead of ``path``
|
|
* :func:`pytest_pycollect_makemodule(fspath: pathlib.Path) <_pytest.hookspec.pytest_pycollect_makemodule>` instead of ``path``
|
|
* :func:`pytest_report_header(startpath: pathlib.Path) <_pytest.hookspec.pytest_report_header>` instead of ``startdir``
|
|
* :func:`pytest_report_collectionfinish(startpath: pathlib.Path) <_pytest.hookspec.pytest_report_collectionfinish>` instead of ``startdir``
|
|
|
|
The accompanying ``py.path.local`` based paths have been deprecated: plugins which manually invoke those hooks should only pass the new ``pathlib.Path`` arguments, and users should change their hook implementations to use the new ``pathlib.Path`` arguments.
|
|
|
|
|
|
Implementing the ``pytest_cmdline_preparse`` hook
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. deprecated:: 7.0
|
|
|
|
Implementing the :func:`pytest_cmdline_preparse <_pytest.hookspec.pytest_cmdline_preparse>` hook has been officially deprecated.
|
|
Implement the :func:`pytest_load_initial_conftests <_pytest.hookspec.pytest_load_initial_conftests>` hook instead.
|
|
|
|
.. code-block:: python
|
|
|
|
def pytest_cmdline_preparse(config: Config, args: List[str]) -> None:
|
|
...
|
|
|
|
|
|
# becomes:
|
|
|
|
|
|
def pytest_load_initial_conftests(
|
|
early_config: Config, parser: Parser, args: List[str]
|
|
) -> None:
|
|
...
|
|
|
|
|
|
Diamond inheritance between :class:`pytest.File` and :class:`pytest.Item`
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. deprecated:: 7.0
|
|
|
|
Inheriting from both Item and file at once has never been supported officially,
|
|
however some plugins providing linting/code analysis have been using this as a hack.
|
|
|
|
This practice is now officially deprecated and a common way to fix this is `example pr fixing inheritance`_.
|
|
|
|
|
|
|
|
.. _example pr fixing inheritance: https://github.com/asmeurer/pytest-flakes/pull/40/files
|
|
|
|
|
|
Backward compatibilities in ``Parser.addoption``
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. deprecated:: 2.4
|
|
|
|
Several behaviors of :meth:`Parser.addoption <pytest.Parser.addoption>` are now
|
|
scheduled for removal in pytest 7 (deprecated since pytest 2.4.0):
|
|
|
|
- ``parser.addoption(..., help=".. %default ..")`` - use ``%(default)s`` instead.
|
|
- ``parser.addoption(..., type="int/string/float/complex")`` - use ``type=int`` etc. instead.
|
|
|
|
|
|
Raising ``unittest.SkipTest`` during collection
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. deprecated:: 7.0
|
|
|
|
Raising :class:`unittest.SkipTest` to skip collection of tests during the
|
|
pytest collection phase is deprecated. Use :func:`pytest.skip` instead.
|
|
|
|
Note: This deprecation only relates to using `unittest.SkipTest` during test
|
|
collection. You are probably not doing that. Ordinary usage of
|
|
:class:`unittest.SkipTest` / :meth:`unittest.TestCase.skipTest` /
|
|
:func:`unittest.skip` in unittest test cases is fully supported.
|
|
|
|
|
|
The ``--strict`` command-line option
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. deprecated:: 6.2
|
|
|
|
The ``--strict`` command-line option has been deprecated in favor of ``--strict-markers``, which
|
|
better conveys what the option does.
|
|
|
|
We have plans to maybe in the future to reintroduce ``--strict`` and make it an encompassing
|
|
flag for all strictness related options (``--strict-markers`` and ``--strict-config``
|
|
at the moment, more might be introduced in the future).
|
|
|
|
|
|
The ``yield_fixture`` function/decorator
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. deprecated:: 6.2
|
|
|
|
``pytest.yield_fixture`` is a deprecated alias for :func:`pytest.fixture`.
|
|
|
|
It has been so for a very long time, so can be search/replaced safely.
|
|
|
|
|
|
The ``pytest_warning_captured`` hook
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. deprecated:: 6.0
|
|
|
|
This hook has an `item` parameter which cannot be serialized by ``pytest-xdist``.
|
|
|
|
Use the ``pytest_warning_recored`` hook instead, which replaces the ``item`` parameter
|
|
by a ``nodeid`` parameter.
|
|
|
|
The ``pytest.collect`` module
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. deprecated:: 6.0
|
|
|
|
The ``pytest.collect`` module is no longer part of the public API, all its names
|
|
should now be imported from ``pytest`` directly instead.
|
|
|
|
|
|
The ``pytest._fillfuncargs`` function
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. deprecated:: 6.0
|
|
|
|
This function was kept for backward compatibility with an older plugin.
|
|
|
|
It's functionality is not meant to be used directly, but if you must replace
|
|
it, use `function._request._fillfixtures()` instead, though note this is not
|
|
a public API and may break in the future.
|
|
|
|
|
|
Removed Features
|
|
----------------
|
|
|
|
As stated in our :ref:`backwards-compatibility` policy, deprecated features are removed only in major releases after
|
|
an appropriate period of deprecation has passed.
|
|
|
|
``--no-print-logs`` command-line option
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. deprecated:: 5.4
|
|
.. versionremoved:: 6.0
|
|
|
|
|
|
The ``--no-print-logs`` option and ``log_print`` ini setting are removed. If
|
|
you used them, please use ``--show-capture`` instead.
|
|
|
|
A ``--show-capture`` command-line option was added in ``pytest 3.5.0`` which allows to specify how to
|
|
display captured output when tests fail: ``no``, ``stdout``, ``stderr``, ``log`` or ``all`` (the default).
|
|
|
|
|
|
.. _resultlog deprecated:
|
|
|
|
Result log (``--result-log``)
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. deprecated:: 4.0
|
|
.. versionremoved:: 6.0
|
|
|
|
The ``--result-log`` option produces a stream of test reports which can be
|
|
analysed at runtime, but it uses a custom format which requires users to implement their own
|
|
parser.
|
|
|
|
The `pytest-reportlog <https://github.com/pytest-dev/pytest-reportlog>`__ plugin provides a ``--report-log`` option, a more standard and extensible alternative, producing
|
|
one JSON object per-line, and should cover the same use cases. Please try it out and provide feedback.
|
|
|
|
The ``pytest-reportlog`` plugin might even be merged into the core
|
|
at some point, depending on the plans for the plugins and number of users using it.
|
|
|
|
``pytest_collect_directory`` hook
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 6.0
|
|
|
|
The ``pytest_collect_directory`` has not worked properly for years (it was called
|
|
but the results were ignored). Users may consider using :func:`pytest_collection_modifyitems <_pytest.hookspec.pytest_collection_modifyitems>` instead.
|
|
|
|
TerminalReporter.writer
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 6.0
|
|
|
|
The ``TerminalReporter.writer`` attribute has been deprecated and should no longer be used. This
|
|
was inadvertently exposed as part of the public API of that plugin and ties it too much
|
|
with ``py.io.TerminalWriter``.
|
|
|
|
Plugins that used ``TerminalReporter.writer`` directly should instead use ``TerminalReporter``
|
|
methods that provide the same functionality.
|
|
|
|
.. _junit-family changed default value:
|
|
|
|
``junit_family`` default value change to "xunit2"
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionchanged:: 6.0
|
|
|
|
The default value of ``junit_family`` option will change to ``xunit2`` in pytest 6.0, which
|
|
is an update of the old ``xunit1`` format and is supported by default in modern tools
|
|
that manipulate this type of file (for example, Jenkins, Azure Pipelines, etc.).
|
|
|
|
Users are recommended to try the new ``xunit2`` format and see if their tooling that consumes the JUnit
|
|
XML file supports it.
|
|
|
|
To use the new format, update your ``pytest.ini``:
|
|
|
|
.. code-block:: ini
|
|
|
|
[pytest]
|
|
junit_family=xunit2
|
|
|
|
If you discover that your tooling does not support the new format, and want to keep using the
|
|
legacy version, set the option to ``legacy`` instead:
|
|
|
|
.. code-block:: ini
|
|
|
|
[pytest]
|
|
junit_family=legacy
|
|
|
|
By using ``legacy`` you will keep using the legacy/xunit1 format when upgrading to
|
|
pytest 6.0, where the default format will be ``xunit2``.
|
|
|
|
In order to let users know about the transition, pytest will issue a warning in case
|
|
the ``--junitxml`` option is given in the command line but ``junit_family`` is not explicitly
|
|
configured in ``pytest.ini``.
|
|
|
|
Services known to support the ``xunit2`` format:
|
|
|
|
* `Jenkins <https://www.jenkins.io/>`__ with the `JUnit <https://plugins.jenkins.io/junit>`__ plugin.
|
|
* `Azure Pipelines <https://azure.microsoft.com/en-us/services/devops/pipelines>`__.
|
|
|
|
Node Construction changed to ``Node.from_parent``
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionchanged:: 6.0
|
|
|
|
The construction of nodes now should use the named constructor ``from_parent``.
|
|
This limitation in api surface intends to enable better/simpler refactoring of the collection tree.
|
|
|
|
This means that instead of :code:`MyItem(name="foo", parent=collector, obj=42)`
|
|
one now has to invoke :code:`MyItem.from_parent(collector, name="foo")`.
|
|
|
|
Plugins that wish to support older versions of pytest and suppress the warning can use
|
|
`hasattr` to check if `from_parent` exists in that version:
|
|
|
|
.. code-block:: python
|
|
|
|
def pytest_pycollect_makeitem(collector, name, obj):
|
|
if hasattr(MyItem, "from_parent"):
|
|
item = MyItem.from_parent(collector, name="foo")
|
|
item.obj = 42
|
|
return item
|
|
else:
|
|
return MyItem(name="foo", parent=collector, obj=42)
|
|
|
|
Note that ``from_parent`` should only be called with keyword arguments for the parameters.
|
|
|
|
|
|
``pytest.fixture`` arguments are keyword only
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 6.0
|
|
|
|
Passing arguments to pytest.fixture() as positional arguments has been removed - pass them by keyword instead.
|
|
|
|
``funcargnames`` alias for ``fixturenames``
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 6.0
|
|
|
|
The ``FixtureRequest``, ``Metafunc``, and ``Function`` classes track the names of
|
|
their associated fixtures, with the aptly-named ``fixturenames`` attribute.
|
|
|
|
Prior to pytest 2.3, this attribute was named ``funcargnames``, and we have kept
|
|
that as an alias since. It is finally due for removal, as it is often confusing
|
|
in places where we or plugin authors must distinguish between fixture names and
|
|
names supplied by non-fixture things such as ``pytest.mark.parametrize``.
|
|
|
|
|
|
.. _pytest.config global deprecated:
|
|
|
|
``pytest.config`` global
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 5.0
|
|
|
|
The ``pytest.config`` global object is deprecated. Instead use
|
|
``request.config`` (via the ``request`` fixture) or if you are a plugin author
|
|
use the ``pytest_configure(config)`` hook. Note that many hooks can also access
|
|
the ``config`` object indirectly, through ``session.config`` or ``item.config`` for example.
|
|
|
|
|
|
.. _`raises message deprecated`:
|
|
|
|
``"message"`` parameter of ``pytest.raises``
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 5.0
|
|
|
|
It is a common mistake to think this parameter will match the exception message, while in fact
|
|
it only serves to provide a custom message in case the ``pytest.raises`` check fails. To prevent
|
|
users from making this mistake, and because it is believed to be little used, pytest is
|
|
deprecating it without providing an alternative for the moment.
|
|
|
|
If you have a valid use case for this parameter, consider that to obtain the same results
|
|
you can just call ``pytest.fail`` manually at the end of the ``with`` statement.
|
|
|
|
For example:
|
|
|
|
.. code-block:: python
|
|
|
|
with pytest.raises(TimeoutError, message="Client got unexpected message"):
|
|
wait_for(websocket.recv(), 0.5)
|
|
|
|
|
|
Becomes:
|
|
|
|
.. code-block:: python
|
|
|
|
with pytest.raises(TimeoutError):
|
|
wait_for(websocket.recv(), 0.5)
|
|
pytest.fail("Client got unexpected message")
|
|
|
|
|
|
If you still have concerns about this deprecation and future removal, please comment on
|
|
`issue #3974 <https://github.com/pytest-dev/pytest/issues/3974>`__.
|
|
|
|
|
|
.. _raises-warns-exec:
|
|
|
|
``raises`` / ``warns`` with a string as the second argument
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 5.0
|
|
|
|
Use the context manager form of these instead. When necessary, invoke ``exec``
|
|
directly.
|
|
|
|
Example:
|
|
|
|
.. code-block:: python
|
|
|
|
pytest.raises(ZeroDivisionError, "1 / 0")
|
|
pytest.raises(SyntaxError, "a $ b")
|
|
|
|
pytest.warns(DeprecationWarning, "my_function()")
|
|
pytest.warns(SyntaxWarning, "assert(1, 2)")
|
|
|
|
Becomes:
|
|
|
|
.. code-block:: python
|
|
|
|
with pytest.raises(ZeroDivisionError):
|
|
1 / 0
|
|
with pytest.raises(SyntaxError):
|
|
exec("a $ b") # exec is required for invalid syntax
|
|
|
|
with pytest.warns(DeprecationWarning):
|
|
my_function()
|
|
with pytest.warns(SyntaxWarning):
|
|
exec("assert(1, 2)") # exec is used to avoid a top-level warning
|
|
|
|
|
|
|
|
|
|
Using ``Class`` in custom Collectors
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
Using objects named ``"Class"`` as a way to customize the type of nodes that are collected in ``Collector``
|
|
subclasses has been deprecated. Users instead should use ``pytest_pycollect_makeitem`` to customize node types during
|
|
collection.
|
|
|
|
This issue should affect only advanced plugins who create new collection types, so if you see this warning
|
|
message please contact the authors so they can change the code.
|
|
|
|
|
|
.. _marks in pytest.parametrize deprecated:
|
|
|
|
marks in ``pytest.mark.parametrize``
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
Applying marks to values of a ``pytest.mark.parametrize`` call is now deprecated. For example:
|
|
|
|
.. code-block:: python
|
|
|
|
@pytest.mark.parametrize(
|
|
"a, b",
|
|
[
|
|
(3, 9),
|
|
pytest.mark.xfail(reason="flaky")(6, 36),
|
|
(10, 100),
|
|
(20, 200),
|
|
(40, 400),
|
|
(50, 500),
|
|
],
|
|
)
|
|
def test_foo(a, b):
|
|
...
|
|
|
|
This code applies the ``pytest.mark.xfail(reason="flaky")`` mark to the ``(6, 36)`` value of the above parametrization
|
|
call.
|
|
|
|
This was considered hard to read and understand, and also its implementation presented problems to the code preventing
|
|
further internal improvements in the marks architecture.
|
|
|
|
To update the code, use ``pytest.param``:
|
|
|
|
.. code-block:: python
|
|
|
|
@pytest.mark.parametrize(
|
|
"a, b",
|
|
[
|
|
(3, 9),
|
|
pytest.param(6, 36, marks=pytest.mark.xfail(reason="flaky")),
|
|
(10, 100),
|
|
(20, 200),
|
|
(40, 400),
|
|
(50, 500),
|
|
],
|
|
)
|
|
def test_foo(a, b):
|
|
...
|
|
|
|
|
|
.. _pytest_funcarg__ prefix deprecated:
|
|
|
|
``pytest_funcarg__`` prefix
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
In very early pytest versions fixtures could be defined using the ``pytest_funcarg__`` prefix:
|
|
|
|
.. code-block:: python
|
|
|
|
def pytest_funcarg__data():
|
|
return SomeData()
|
|
|
|
Switch over to the ``@pytest.fixture`` decorator:
|
|
|
|
.. code-block:: python
|
|
|
|
@pytest.fixture
|
|
def data():
|
|
return SomeData()
|
|
|
|
|
|
|
|
[pytest] section in setup.cfg files
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
``[pytest]`` sections in ``setup.cfg`` files should now be named ``[tool:pytest]``
|
|
to avoid conflicts with other distutils commands.
|
|
|
|
|
|
.. _metafunc.addcall deprecated:
|
|
|
|
Metafunc.addcall
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
``Metafunc.addcall`` was a precursor to the current parametrized mechanism. Users should use
|
|
:meth:`pytest.Metafunc.parametrize` instead.
|
|
|
|
Example:
|
|
|
|
.. code-block:: python
|
|
|
|
def pytest_generate_tests(metafunc):
|
|
metafunc.addcall({"i": 1}, id="1")
|
|
metafunc.addcall({"i": 2}, id="2")
|
|
|
|
Becomes:
|
|
|
|
.. code-block:: python
|
|
|
|
def pytest_generate_tests(metafunc):
|
|
metafunc.parametrize("i", [1, 2], ids=["1", "2"])
|
|
|
|
|
|
.. _cached_setup deprecated:
|
|
|
|
``cached_setup``
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
``request.cached_setup`` was the precursor of the setup/teardown mechanism available to fixtures.
|
|
|
|
Example:
|
|
|
|
.. code-block:: python
|
|
|
|
@pytest.fixture
|
|
def db_session():
|
|
return request.cached_setup(
|
|
setup=Session.create, teardown=lambda session: session.close(), scope="module"
|
|
)
|
|
|
|
This should be updated to make use of standard fixture mechanisms:
|
|
|
|
.. code-block:: python
|
|

.. _pytest_plugins in non-top-level conftest files deprecated:
|
|
|
|
pytest_plugins in non-top-level conftest files
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
Defining :globalvar:`pytest_plugins` is now deprecated in non-top-level conftest.py
|
|
files because they will activate referenced plugins *globally*, which is surprising because for all other pytest
|
|
features ``conftest.py`` files are only *active* for tests at or below it.
|
|
|
|
|
|
.. _config.warn and node.warn deprecated:
|
|
|
|
``Config.warn`` and ``Node.warn``
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
Those methods were part of the internal pytest warnings system, but since ``3.8`` pytest is using the builtin warning
|
|
system for its own warnings, so those two functions are now deprecated.
|
|
|
|
``Config.warn`` should be replaced by calls to the standard ``warnings.warn``, example:
|
|
|
|
.. code-block:: python
|
|
|
|
config.warn("C1", "some warning")
|
|
|
|
Becomes:
|
|
|
|
.. code-block:: python
|
|
|
|
warnings.warn(pytest.PytestWarning("some warning"))
|
|
|
|
``Node.warn`` now supports two signatures:
|
|
|
|
* ``node.warn(PytestWarning("some message"))``: is now the **recommended** way to call this function.
|
|
The warning instance must be a PytestWarning or subclass.
|
|
|
|
* ``node.warn("CI", "some message")``: this code/message form has been **removed** and should be converted to the warning instance form above.
|
|
|
|
.. _record_xml_property deprecated:
|
|
|
|
record_xml_property
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
The ``record_xml_property`` fixture is now deprecated in favor of the more generic ``record_property``, which
|
|
can be used by other consumers (for example ``pytest-html``) to obtain custom information about the test run.
|
|
|
|
This is just a matter of renaming the fixture as the API is the same:
|
|
|
|
.. code-block:: python
|
|
|
|
def test_foo(record_xml_property):
|
|
...
|
|
|
|
Change to:
|
|
|
|
.. code-block:: python
|
|
|
|
def test_foo(record_property):
|
|
...
|
|
|
|
|
|
.. _passing command-line string to pytest.main deprecated:
|
|
|
|
Passing command-line string to ``pytest.main()``
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
Passing a command-line string to ``pytest.main()`` is deprecated:
|
|
|
|
.. code-block:: python
|
|
|
|
pytest.main("-v -s")
|
|
|
|
Pass a list instead:
|
|
|
|
.. code-block:: python
|
|
|
|
pytest.main(["-v", "-s"])
|
|
|
|
|
|
By passing a string, users expect that pytest will interpret that command-line using the shell rules they are working
|
|
on (for example ``bash`` or ``Powershell``), but this is very hard/impossible to do in a portable way.
|
|
|
|
|
|
.. _calling fixtures directly deprecated:
|
|
|
|
Calling fixtures directly
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
Calling a fixture function directly, as opposed to request them in a test function, is deprecated.
|
|
|
|
For example:
|
|
|
|
.. code-block:: python
|
|
|
|
@pytest.fixture
|
|
def cell():
|
|
return ...
|
|
|
|
|
|
@pytest.fixture
|
|
def full_cell():
|
|
cell = cell()
|
|
cell.make_full()
|
|
return cell
|
|
|
|
This is a great source of confusion to new users, which will often call the fixture functions and request them from test functions interchangeably, which breaks the fixture resolution model.
|
|
|
|
In those cases just request the function directly in the dependent fixture:
|
|
|
|
.. code-block:: python
|
|
|
|
@pytest.fixture
|
|
def cell():
|
|
return ...
|
|
|
|
|
|
@pytest.fixture
|
|
def full_cell(cell):
|
|
cell.make_full()
|
|
return cell
|
|
|
|
Alternatively if the fixture function is called multiple times inside a test (making it hard to apply the above pattern) or
|
|
if you would like to make minimal changes to the code, you can create a fixture which calls the original function together
|
|
with the ``name`` parameter:
|
|
|
|
.. code-block:: python
|
|
|
|
def cell():
|
|
return ...
|
|
|
|
|
|
@pytest.fixture(name="cell")
|
|
def cell_fixture():
|
|
return cell()
|
|
|
|
|
|
.. _yield tests deprecated:
|
|
|
|
``yield`` tests
|
|
~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
pytest supported ``yield``-style tests, where a test function actually ``yield`` functions and values
|
|
that are then turned into proper test methods. Example:
|
|
|
|
.. code-block:: python
|
|
|
|
def check(x, y):
|
|
assert x ** x == y
|
|
|
|
|
|
def test_squared():
|
|
yield check, 2, 4
|
|
yield check, 3, 9
|
|
|
|
This would result into two actual test functions being generated.
|
|
|
|
This form of test function doesn't support fixtures properly, and users should switch to ``pytest.mark.parametrize``:
|
|
|
|
.. code-block:: python
|
|
|
|
@pytest.mark.parametrize("x, y", [(2, 4), (3, 9)])
|
|
def test_squared(x, y):
|
|
assert x ** x == y
|
|
|
|
.. _internal classes accessed through node deprecated:
|
|
|
|
Internal classes accessed through ``Node``
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
Access of ``Module``, ``Function``, ``Class``, ``Instance``, ``File`` and ``Item`` through ``Node`` instances now issue
|
|
this warning:
|
|
|
|
.. code-block:: text
|
|
|
|
usage of Function.Module is deprecated, please use pytest.Module instead
|
|
|
|
Users should just ``import pytest`` and access those objects using the ``pytest`` module.
|
|
|
|
This has been documented as deprecated for years, but only now we are actually emitting deprecation warnings.
|
|
|
|
``Node.get_marker``
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
As part of a large :ref:`marker-revamp`, ``_pytest.nodes.Node.get_marker`` is removed. See
|
|
:ref:`the documentation <update marker code>` on tips on how to update your code.
|
|
|
|
|
|
``somefunction.markname``
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
As part of a large :ref:`marker-revamp` we already deprecated using ``MarkInfo``
|
|
the only correct way to get markers of an element is via ``node.iter_markers(name)``.
|
|
|
|
|
|
.. _pytest.namespace deprecated:
|
|
|
|
``pytest_namespace``
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
.. versionremoved:: 4.0
|
|
|
|
This hook is deprecated because it greatly complicates the pytest internals regarding configuration and initialization, making some
|
|
bug fixes and refactorings impossible.
|
|
|
|
Example of usage:
|
|
|
|
.. code-block:: python
|
|
|
|
class MySymbol:
|
|
...
|
|
|
|
|
|
def pytest_namespace():
|
|
return {"my_symbol": MySymbol()}
|
|
|
|
|
|
Plugin authors relying on this hook should instead require that users now import the plugin modules directly (with an appropriate public API).
|
|
|
|
As a stopgap measure, plugin authors may still inject their names into pytest's namespace, usually during ``pytest_configure``:
|
|
|
|
.. code-block:: python
|
|
|
|
import pytest
|
|
|
|
|
|
def pytest_configure():
|
|
pytest.my_symbol = MySymbol()
|
