pytest 3.10.0 (2018-11-03)
|
||||
==========================
|
||||
|
||||
Features
|
||||
--------
|
||||
|
||||
- `#2619 <https://github.com/pytest-dev/pytest/issues/2619>`_: Resume capturing output after ``continue`` with ``__import__("pdb").set_trace()``.
|
||||
|
||||
This also adds a new ``pytest_leave_pdb`` hook, and passes in ``pdb`` to the
|
||||
existing ``pytest_enter_pdb`` hook.
|
||||
|
||||
|
||||
- `#4147 <https://github.com/pytest-dev/pytest/issues/4147>`_: Add ``-sw``, ``--stepwise`` as an alternative to ``--lf -x`` for stopping at the first failure, but starting the next test invocation from that test. See `the documentation <https://docs.pytest.org/en/latest/cache.html#stepwise>`__ for more info.
|
||||
|
||||
|
||||
- `#4188 <https://github.com/pytest-dev/pytest/issues/4188>`_: Make ``--color`` emit colorful dots when not running in verbose mode. Earlier, it would only colorize the test-by-test output if ``--verbose`` was also passed.
|
||||
|
||||
|
||||
- `#4225 <https://github.com/pytest-dev/pytest/issues/4225>`_: Improve performance with collection reporting in non-quiet mode with terminals.
|
||||
|
||||
The "collecting …" message is only printed/updated every 0.5s.
|
||||
|
||||
|
||||
|
||||
Bug Fixes
|
||||
---------
|
||||
|
||||
- `#2701 <https://github.com/pytest-dev/pytest/issues/2701>`_: Fix false ``RemovedInPytest4Warning: usage of Session... is deprecated, please use pytest`` warnings.
|
||||
|
||||
|
||||
- `#4046 <https://github.com/pytest-dev/pytest/issues/4046>`_: Fix problems with running tests in package ``__init__.py`` files.
|
||||
|
||||
|
||||
- `#4260 <https://github.com/pytest-dev/pytest/issues/4260>`_: Swallow warnings during anonymous compilation of source.
|
||||
|
||||
|
||||
- `#4262 <https://github.com/pytest-dev/pytest/issues/4262>`_: Fix access denied error when deleting stale directories created by ``tmpdir`` / ``tmp_path``.
|
||||
|
||||
|
||||
- `#611 <https://github.com/pytest-dev/pytest/issues/611>`_: Naming a fixture ``request`` will now raise a warning: the ``request`` fixture is internal and
|
||||
should not be overwritten as it will lead to internal errors.
|
||||
|
||||
|
||||
|
||||
Improved Documentation
|
||||
----------------------
|
||||
|
||||
- `#4255 <https://github.com/pytest-dev/pytest/issues/4255>`_: Added missing documentation about the fact that module names passed to filter warnings are not regex-escaped.
|
||||
|
||||
|
||||
|
||||
Trivial/Internal Changes
|
||||
------------------------
|
||||
|
||||

|
||||
|
||||
|
||||
- `#4277 <https://github.com/pytest-dev/pytest/issues/4277>`_: pdb: improve message about output capturing with ``set_trace``.
|
||||
|
||||
Do not display "IO-capturing turned off/on" when ``-s`` is used to avoid
|
||||
confusion.
|
||||
|
||||
|
||||
- `#4279 <https://github.com/pytest-dev/pytest/issues/4279>`_: Improve message and stack level of warnings issued by ``monkeypatch.setenv`` when the value of the environment variable is not a ``str``.

Flaky tests
|
||||
-----------
|
||||
|
||||
A "flaky" test is one that exhibits intermittent or sporadic failure, that seems to have non-deterministic behaviour. Sometimes it passes, sometimes it fails, and it's not clear why. This page discusses pytest features that can help and other general strategies for identifying, fixing or mitigating them.
|
||||
|
||||
Why flaky tests are a problem
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Flaky tests are particularly troublesome when a continuous integration (CI) server is being used, so that all tests must pass before a new code change can be merged. If the test result is not a reliable signal -- that a test failure means the code change broke the test -- developers can become mistrustful of the test results, which can lead to overlooking genuine failures. It is also a source of wasted time as developers must re-run test suites and investigate spurious failures.
|
||||
|
||||
|
||||
Potential root causes
|
||||
^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
System state
|
||||
~~~~~~~~~~~~
|
||||
|
||||
Broadly speaking, a flaky test indicates that the test relies on some system state that is not being appropriately controlled - the test environment is not sufficiently isolated. Higher level tests are more likely to be flaky as they rely on more state.
|
||||
|
||||
Flaky tests sometimes appear when a test suite is run in parallel (such as use of pytest-xdist). This can indicate a test is reliant on test ordering.
|
||||
|
||||
- Perhaps a different test is failing to clean up after itself and leaving behind data which causes the flaky test to fail.
|
||||
- The flaky test is reliant on data from a previous test that doesn't clean up after itself, and in parallel runs that previous test is not always present
|
||||
- Tests that modify global state typically cannot be run in parallel.
|
||||
|
||||
|
||||
Overly strict assertion
|
||||
~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Overly strict assertions can cause problems with floating point comparison as well as timing issues. `pytest.approx <https://docs.pytest.org/en/latest/reference.html#pytest-approx>`_ is useful here.
|
||||
|
||||
|
||||
Pytest features
|
||||
^^^^^^^^^^^^^^^
|
||||
|
||||
Xfail strict
|
||||
~~~~~~~~~~~~
|
||||
|
||||
:ref:`pytest.mark.xfail ref` with ``strict=False`` can be used to mark a test so that its failure does not cause the whole build to break. This could be considered like a manual quarantine, and is rather dangerous to use permanently.
|
||||
|
||||
|
||||
PYTEST_CURRENT_TEST
|
||||
~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
:ref:`pytest current test env` may be useful for figuring out "which test got stuck".
|
||||
|
||||
|
||||
Plugins
|
||||
~~~~~~~
|
||||
|
||||
Rerunning any failed tests can mitigate the negative effects of flaky tests by giving them additional chances to pass, so that the overall build does not fail. Several pytest plugins support this:
|
||||
|
||||
* `flaky <https://github.com/box/flaky>`_
|
||||
* `pytest-flakefinder <https://github.com/dropbox/pytest-flakefinder>`_ - `blog post <https://blogs.dropbox.com/tech/2016/03/open-sourcing-pytest-tools/>`_
|
||||
* `pytest-rerunfailures <https://github.com/pytest-dev/pytest-rerunfailures>`_
|
||||
* `pytest-replay <https://github.com/ESSS/pytest-replay>`_: This plugin helps to reproduce locally crashes or flaky tests observed during CI runs.
|
||||
|
||||
Plugins to deliberately randomize tests can help expose tests with state problems:
|
||||
|
||||
* `pytest-random-order <https://github.com/jbasko/pytest-random-order>`_
|
||||
* `pytest-randomly <https://github.com/pytest-dev/pytest-randomly>`_
|
||||
|
||||
|
||||
Other general strategies
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
Split up test suites
|
||||
~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
It can be common to split a single test suite into two, such as unit vs integration, and only use the unit test suite as a CI gate. This also helps keep build times manageable as high level tests tend to be slower. However, it means it does become possible for code that breaks the build to be merged, so extra vigilance is needed for monitoring the integration test results.
|
||||
|
||||
|
||||
Video/screenshot on failure
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
For UI tests these are important for understanding what the state of the UI was when the test failed. pytest-splinter can be used with plugins like pytest-bdd and can `save a screenshot on test failure <https://pytest-splinter.readthedocs.io/en/latest/#automatic-screenshots-on-test-failure>`_, which can help to isolate the cause.
|
||||
|
||||
|
||||
Delete or rewrite the test
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
If the functionality is covered by other tests, perhaps the test can be removed. If not, perhaps it can be rewritten at a lower level which will remove the flakiness or make its source more apparent.
|
||||
|
||||
|
||||
Quarantine
|
||||
~~~~~~~~~~
|
||||
|
||||
Mark Lapierre discusses the `Pros and Cons of Quarantined Tests <https://dev.to/mlapierre/pros-and-cons-of-quarantined-tests-2emj>`_ in a post from 2018.
|
||||
|
||||
|
||||
|
||||
CI tools that rerun on failure
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Azure Pipelines (the Azure cloud CI/CD tool, formerly Visual Studio Team Services or VSTS) has a feature to `identify flaky tests <https://docs.microsoft.com/en-us/azure/devops/release-notes/2017/dec-11-vsts#identify-flaky-tests>`_ and rerun failed tests.
