Changelogs

pytest-cov -> 2.4.0

2.4.0

---

• Added a "disarm" option: --no-cov. It will disable coverage measurements. Contributed by Zoltan Kozma in
  PR135 <https://github.com/pytest-dev/pytest-cov/pull/135>_.

WARNING: Do not put this in your configuration files, it's meant to be an one-off for situations where you want to
disable coverage from command line.

• Fixed broken exception handling on .pth file. See 136 <https://github.com/pytest-dev/pytest-cov/issues/136>_.

2.3.1

---

• Fixed regression causing spurious errors when xdist was used. See 124 <https://github.com/pytest-dev/pytest-cov/issues/124>_.
• Fixed DeprecationWarning about incorrect addoption use. Contributed by Florian Bruhin in PR127 <https://github.com/pytest-dev/pytest-cov/pull/127>_.
• Fixed deprecated use of funcarg fixture API. Contributed by Daniel Hahler in PR125 <https://github.com/pytest-dev/pytest-cov/pull/125>_.

2.3.0

---

• Add support for specifying output location for html, xml, and annotate report.
  Contributed by Patrick Lannigan in PR113 <https://github.com/pytest-dev/pytest-cov/pull/113>_.
• Fix bug hiding test failure when cov-fail-under failed.
• For coverage >= 4.0, match the default behaviour of coverage report and
  error if coverage fails to find the source instead of just printing a warning.
  Contributed by David Szotten in PR116 <https://github.com/pytest-dev/pytest-cov/pull/116>_.
• Fixed bug occurred when bare --cov parameter was used with xdist.
  Contributed by Michael Elovskikh in PR120 <https://github.com/pytest-dev/pytest-cov/pull/120>_.
• Add support for skip_covered and added --cov-report=term-skip-covered command
  line options. Contributed by Saurabh Kumar in PR115 <https://github.com/pytest-dev/pytest-cov/pull/115>_.

2.2.1

---

• Fixed incorrect merging of coverage data when xdist was used and coverage was >= 4.0.

2.2.0

---

• Added support for changing working directory in tests. Previously changing working
  directory would disable coverage measurements in suprocesses.
• Fixed broken handling for --cov-report=annotate.

2.1.0

---

• Added support for coverage 4.0b2.
• Added the --cov-append command line options. Contributed by Christian Ledermann
  in PR80 <https://github.com/pytest-dev/pytest-cov/pull/80>_.

2.0.0

---

• Added --cov-fail-under, akin to the new fail_under option in coverage-4.0
  (automatically activated if there's a [report] fail_under = ... in .coveragerc).
• Changed --cov-report=term to automatically upgrade to --cov-report=term-missing
  if there's [run] show_missing = True in .coveragerc.
• Changed --cov so it can be used with no path argument (in wich case the source
  settings from .coveragerc will be used instead).
• Fixed .pth installation to work in all cases (install, easy_install, wheels, develop etc).
• Fixed .pth uninstallation to work for wheel installs.
• Support for coverage 4.0.
• Data file suffixing changed to use coverage's data_suffix=True option (instead of the
  custom suffixing).
• Avoid warning about missing coverage data (just like coverage.control.process_startup).
• Fixed a race condition when running with xdist (all the workers tried to combine the files).
  It's possible that this issue is not present in pytest-cov 1.8.X.

1.8.2

---

• N/A

pytest-mock -> 1.5.0

1.5.0

---

• New mocker.mock_module variable points to the underlying mock module being used
  (unittest.mock or mock).
  Thanks blueyed_ for the request (71_).

.. _71: pytest-dev/pytest-mock#71

1.4.0

---

• New configuration variable, mock_use_standalone_module (defaults to False). This forces
  the plugin to import mock instead of unittest.mock on Python 3. This is useful to import
  a newer version than the one available in the Python distribution.

• Previously the plugin would first try to import mock and fallback to unittest.mock
  in case of an ImportError, but this behavior has been removed because it could hide
  hard to debug import errors (68_).

• Now mock (Python 2) and unittest.mock (Python 3) are lazy-loaded to make it possible to
  implement the new mock_use_standlone_module configuration option. As a consequence of this
  the undocumented pytest_mock.mock_module variable, which pointed to the actual mock module
  being used by the plugin, has been removed.

• DEFAULT <https://docs.python.org/3/library/unittest.mock.htmldefault>_ is now available from
  the mocker fixture.

.. _68: pytest-dev/pytest-mock#68

1.3.0

---

• Add support for Python 3.6. Thanks hackebrot_ for the report (59_).

• mock.mock_open is now aliased as mocker.mock_open for convenience.
  Thanks pokidovea_ for the PR (66_).

.. _66: pytest-dev/pytest-mock#66

1.2

---

• Try to import mock first instead of unittest.mock. This gives the user flexibility
  to install a newer mock version from PyPI instead of using the one available in the
  Python distribution.
  Thanks wcooley_ for the PR (54_).

• mock.sentinel is now aliased as mocker.sentinel for convenience.
  Thanks kjwilcox_ for the PR (56_).

.. _56: pytest-dev/pytest-mock#56

1.1

---

• From this version onward, pytest-mock is licensed under the MIT_ license (45_).

• Now the plugin also adds introspection information on differing call arguments when
  calling helper methods such as assert_called_once_with. The extra introspection
  information is similar to pytest's and can be disabled with the mock_traceback_monkeypatch
  option.
  Thanks asfaltboy_ for the PR (36_).

• mocker.stub() now allows passing in the name for the constructed Mock <https://docs.python.org/3/library/unittest.mock.htmlthe-mock-class>_
  object instead of having to set it using the internal _mock_name attribute
  directly. This is useful for debugging as the name is used in the mock's
  repr string as well as related assertion failure messages.
  Thanks jurko-gospodnetic_ for the PR (40_).

• Monkey patching mock module for friendlier tracebacks is automatically disabled
  with the --tb=native option. The underlying
  mechanism used to suppress traceback entries from mock module does not work with that option
  anyway plus it generates confusing messages on Python 3.5 due to exception chaining (44).
  Thanks blueyed for the report.

• mock.call is now aliased as mocker.call for convenience.
  Thanks jhermann_ for the PR (49_).

.. _42: pytest-dev/pytest-mock#42

0.11.0

---

• PropertyMock <https://docs.python.org/3/library/unittest.mock.htmlunittest.mock.PropertyMock>_
  is now accessible from mocker.
  Thanks satyrius_ for the PR (32_).

• Fix regression using one of the assert_* methods in patched
  functions which receive a parameter named method.

0.10.1

---

• Fix regression in frozen tests due to distutils import dependency.
  Thanks The-Compiler_ for the report (29_).

• Fix regression when using pytest-mock with pytest-2.7.X.

0.10

---

• pytest-mock now monkeypatches the mock library to improve pytest output
  for failures of mock call assertions like Mock.assert_called_with().
  Thanks to Chronial_ for idea and PR (26, 27)!

0.9.0

---

• New mocker.resetall function, which calls reset_mock() in all mocked
  objects up to that point. Thanks to mathrick_ for the PR!

0.8.1

---

• pytest-mock is now also available as a wheel. Thanks rouge8_ for the PR!

0.8.0

---

• mock.ANY is now accessible from the mocker fixture (17), thanks tigarmo for the PR!

.. _17: pytest-dev/pytest-qt#17

0.7.0

---

Thanks to fogo_, mocker.spy can now prey upon staticmethods and classmethods. 😄

0.6.0

---

• Two new auxiliary methods, spy and stub. See README for usage.
  (Thanks fogo_ for complete PR!)

0.5.0

---

• Mock and MagicMock are now accessible from the mocker fixture,
  many thanks to marcwebbie_ for the complete PR!

0.4.3

---

• mocker fixture now returns the same object (8). Many thanks to RonnyPfannschmidt for the PR!

.. _8: pytest-dev/pytest-qt#8

0.4.2

---

• Small fix, no longer using wheel as an alternate package since it
  conditionally depends on mock module based on Python version,
  as Python >= 3.3 already includes unittest.mock.
  Many thanks to The-Compiler_ for letting me know and providing a PR with the fix!

0.4.1

---

• Small release that just uses pytest_mock as the name of the plugin,
  instead of pytest-mock: this makes it simple to depend on this plugin
  explicitly using pytest_plugins module variable mechanism.

0.4.0

---

• Changed fixture name from mock into mocker because it conflicted
  with the actual mock module, which made using it awkward when access to both
  the module and the fixture were required within a test.

Thanks kmosher_ for request and discussion in 4_. 😄

.. _4: pytest-dev/pytest-qt#4

0.3.0

---

• Fixed bug 2_, where a patch would not be uninstalled correctly after
  patching the same object twice.

0.2.0

---

• Added patch.dict support.

0.1.0

---

First release.

requests -> 2.13.0

2.13.0

+++++++++++++++++++

Features

• Only load the idna library when we've determined we need it. This will
  save some memory for users.

Miscellaneous

• Updated bundled urllib3 to 1.20.
• Updated bundled idna to 2.2.

2.12.5

+++++++++++++++++++

Bugfixes

• Fixed an issue with JSON encoding detection, specifically detecting
  big-endian UTF-32 with BOM.

2.12.4

+++++++++++++++++++

Bugfixes

• Fixed regression from 2.12.2 where non-string types were rejected in the
  basic auth parameters. While support for this behaviour has been readded,
  the behaviour is deprecated and will be removed in the future.

2.12.3

+++++++++++++++++++

Bugfixes

• Fixed regression from v2.12.1 for URLs with schemes that begin with "http".
  These URLs have historically been processed as though they were HTTP-schemed
  URLs, and so have had parameters added. This was removed in v2.12.2 in an
  overzealous attempt to resolve problems with IDNA-encoding those URLs. This
  change was reverted: the other fixes for IDNA-encoding have been judged to
  be sufficient to return to the behaviour Requests had before v2.12.0.

2.12.2

+++++++++++++++++++

Bugfixes

• Fixed several issues with IDNA-encoding URLs that are technically invalid but
  which are widely accepted. Requests will now attempt to IDNA-encode a URL if
  it can but, if it fails, and the host contains only ASCII characters, it will
  be passed through optimistically. This will allow users to opt-in to using
  IDNA2003 themselves if they want to, and will also allow technically invalid
  but still common hostnames.
• Fixed an issue where URLs with leading whitespace would raise
  InvalidSchema errors.
• Fixed an issue where some URLs without the HTTP or HTTPS schemes would still
  have HTTP URL preparation applied to them.
• Fixed an issue where Unicode strings could not be used in basic auth.
• Fixed an issue encountered by some Requests plugins where constructing a
  Response object would cause Response.content to raise an
  AttributeError.

2.12.1

+++++++++++++++++++

Bugfixes

• Updated setuptools 'security' extra for the new PyOpenSSL backend in urllib3.

Miscellaneous

• Updated bundled urllib3 to 1.19.1.

2.12.0

+++++++++++++++++++

Improvements

• Updated support for internationalized domain names from IDNA2003 to IDNA2008.
  This updated support is required for several forms of IDNs and is mandatory
  for .de domains.
• Much improved heuristics for guessing content lengths: Requests will no
  longer read an entire StringIO into memory.
• Much improved logic for recalculating Content-Length headers for
  PreparedRequest objects.
• Improved tolerance for file-like objects that have no tell method but
  do have a seek method.
• Anything that is a subclass of Mapping is now treated like a dictionary
  by the data= keyword argument.
• Requests now tolerates empty passwords in proxy credentials, rather than
  stripping the credentials.
• If a request is made with a file-like object as the body and that request is
  redirected with a 307 or 308 status code, Requests will now attempt to
  rewind the body object so it can be replayed.

Bugfixes

• When calling response.close, the call to close will be propagated
  through to non-urllib3 backends.
• Fixed issue where the ALL_PROXY environment variable would be preferred
  over scheme-specific variables like HTTP_PROXY.
• Fixed issue where non-UTF8 reason phrases got severely mangled by falling
  back to decoding using ISO 8859-1 instead.
• Fixed a bug where Requests would not correctly correlate cookies set when
  using custom Host headers if those Host headers did not use the native
  string type for the platform.

Miscellaneous

• Updated bundled urllib3 to 1.19.
• Updated bundled certifi certs to 2016.09.26.

2.11.1

+++++++++++++++++++

Bugfixes

• Fixed a bug when using iter_content with decode_unicode=True for
  streamed bodies would raise AttributeError. This bug was introduced in
  2.11.
• Strip Content-Type and Transfer-Encoding headers from the header block when
  following a redirect that transforms the verb from POST/PUT to GET.

2.11.0

+++++++++++++++++++

Improvements

• Added support for the ALL_PROXY environment variable.
• Reject header values that contain leading whitespace or newline characters to
  reduce risk of header smuggling.

Bugfixes

• Fixed occasional TypeError when attempting to decode a JSON response that
  occurred in an error case. Now correctly returns a ValueError.
• Requests would incorrectly ignore a non-CIDR IP address in the NO_PROXY
  environment variables: Requests now treats it as a specific IP.
• Fixed a bug when sending JSON data that could cause us to encounter obscure
  OpenSSL errors in certain network conditions (yes, really).
• Added type checks to ensure that iter_content only accepts integers and
  None for chunk sizes.
• Fixed issue where responses whose body had not been fully consumed would have
  the underlying connection closed but not returned to the connection pool,
  which could cause Requests to hang in situations where the HTTPAdapter
  had been configured to use a blocking connection pool.

Miscellaneous

• Updated bundled urllib3 to 1.16.
• Some previous releases accidentally accepted non-strings as acceptable header values. This release does not.

2.10.0

+++++++++++++++++++

New Features

• SOCKS Proxy Support! (requires PySocks; $ pip install requests[socks])

Miscellaneous

• Updated bundled urllib3 to 1.15.1.

2.9.2

++++++++++++++++++

Improvements

• Change built-in CaseInsensitiveDict (used for headers) to use OrderedDict
  as its underlying datastore.

Bugfixes

• Don't use redirect_cache if allow_redirects=False
• When passed objects that throw exceptions from tell(), send them via
  chunked transfer encoding instead of failing.
• Raise a ProxyError for proxy related connection issues.

2.9.1

++++++++++++++++++

Bugfixes

• Resolve regression introduced in 2.9.0 that made it impossible to send binary
  strings as bodies in Python 3.
• Fixed errors when calculating cookie expiration dates in certain locales.

Miscellaneous

• Updated bundled urllib3 to 1.13.1.

2.9.0

++++++++++++++++++

Minor Improvements (Backwards compatible)

• The verify keyword argument now supports being passed a path to a
  directory of CA certificates, not just a single-file bundle.
• Warnings are now emitted when sending files opened in text mode.
• Added the 511 Network Authentication Required status code to the status code
  registry.

Bugfixes

• For file-like objects that are not seeked to the very beginning, we now
  send the content length for the number of bytes we will actually read, rather
  than the total size of the file, allowing partial file uploads.
• When uploading file-like objects, if they are empty or have no obvious
  content length we set Transfer-Encoding: chunked rather than
  Content-Length: 0.
• We correctly receive the response in buffered mode when uploading chunked
  bodies.
• We now handle being passed a query string as a bytestring on Python 3, by
  decoding it as UTF-8.
• Sessions are now closed in all cases (exceptional and not) when using the
  functional API rather than leaking and waiting for the garbage collector to
  clean them up.
• Correctly handle digest auth headers with a malformed qop directive that
  contains no token, by treating it the same as if no qop directive was
  provided at all.
• Minor performance improvements when removing specific cookies by name.

Miscellaneous

• Updated urllib3 to 1.13.

2.8.1

++++++++++++++++++

Bugfixes

• Update certificate bundle to match certifi 2015.9.6.2's weak certificate
  bundle.
• Fix a bug in 2.8.0 where requests would raise ConnectTimeout instead of
  ConnectionError
• When using the PreparedRequest flow, requests will now correctly respect the
  json parameter. Broken in 2.8.0.
• When using the PreparedRequest flow, requests will now correctly handle a
  Unicode-string method name on Python 2. Broken in 2.8.0.

2.8.0

++++++++++++++++++

Minor Improvements (Backwards Compatible)

• Requests now supports per-host proxies. This allows the proxies
  dictionary to have entries of the form
  {'<scheme>://<hostname>': '<proxy>'}. Host-specific proxies will be used
  in preference to the previously-supported scheme-specific ones, but the
  previous syntax will continue to work.
• Response.raise_for_status now prints the URL that failed as part of the
  exception message.
• requests.utils.get_netrc_auth now takes an raise_errors kwarg,
  defaulting to False. When True, errors parsing .netrc files cause
  exceptions to be thrown.
• Change to bundled projects import logic to make it easier to unbundle
  requests downstream.
• Changed the default User-Agent string to avoid leaking data on Linux: now
  contains only the requests version.

Bugfixes

• The json parameter to post() and friends will now only be used if
  neither data nor files are present, consistent with the
  documentation.
• We now ignore empty fields in the NO_PROXY environment variable.
• Fixed problem where httplib.BadStatusLine would get raised if combining
  stream=True with contextlib.closing.
• Prevented bugs where we would attempt to return the same connection back to
  the connection pool twice when sending a Chunked body.
• Miscellaneous minor internal changes.
• Digest Auth support is now thread safe.

Updates

• Updated urllib3 to 1.12.

2.7.0

++++++++++++++++++

This is the first release that follows our new release process. For more, see
our documentation <http://docs.python-requests.org/en/latest/community/release-process/>_.

Bugfixes

• Updated urllib3 to 1.10.4, resolving several bugs involving chunked transfer
  encoding and response framing.

2.6.2

++++++++++++++++++

Bugfixes

• Fix regression where compressed data that was sent as chunked data was not
  properly decompressed. (2561)

2.6.1

++++++++++++++++++

Bugfixes

• Remove VendorAlias import machinery introduced in v2.5.2.

• Simplify the PreparedRequest.prepare API: We no longer require the user to
  pass an empty list to the hooks keyword argument. (c.f. 2552)

• Resolve redirects now receives and forwards all of the original arguments to
  the adapter. (2503)

• Handle UnicodeDecodeErrors when trying to deal with a unicode URL that
  cannot be encoded in ASCII. (2540)

• Populate the parsed path of the URI field when performing Digest
  Authentication. (2426)

• Copy a PreparedRequest's CookieJar more reliably when it is not an instance
  of RequestsCookieJar. (2527)

2.6.0

++++++++++++++++++

Bugfixes

• CVE-2015-2296: Fix handling of cookies on redirect. Previously a cookie
  without a host value set would use the hostname for the redirected URL
  exposing requests users to session fixation attacks and potentially cookie
  stealing. This was disclosed privately by Matthew Daley of
  BugFuzz <https://bugfuzz.com>_. This affects all versions of requests from
  v2.1.0 to v2.5.3 (inclusive on both ends).

• Fix error when requests is an install_requires dependency and python setup.py test is run. (2462)

• Fix error when urllib3 is unbundled and requests continues to use the
  vendored import location.

• Include fixes to urllib3's header handling.

• Requests' handling of unvendored dependencies is now more restrictive.

Features and Improvements

• Support bytearrays when passed as parameters in the files argument.
  (2468)

• Avoid data duplication when creating a request with str, bytes, or
  bytearray input to the files argument.

2.5.3

++++++++++++++++++

Bugfixes

• Revert changes to our vendored certificate bundle. For more context see
  (2455, 2456, and http://bugs.python.org/issue23476)

2.5.2

++++++++++++++++++

Features and Improvements

• Add sha256 fingerprint support. (shazow/urllib3540_)

• Improve the performance of headers. (shazow/urllib3544_)

Bugfixes

• Copy pip's import machinery. When downstream redistributors remove
  requests.packages.urllib3 the import machinery will continue to let those
  same symbols work. Example usage in requests' documentation and 3rd-party
  libraries relying on the vendored copies of urllib3 will work without having
  to fallback to the system urllib3.

• Attempt to quote parts of the URL on redirect if unquoting and then quoting
  fails. (2356)

• Fix filename type check for multipart form-data uploads. (2411)

• Properly handle the case where a server issuing digest authentication
  challenges provides both auth and auth-int qop-values. (2408)

• Fix a socket leak. (shazow/urllib3549_)

• Fix multiple Set-Cookie headers properly. (shazow/urllib3534_)

• Disable the built-in hostname verification. (shazow/urllib3526_)

• Fix the behaviour of decoding an exhausted stream. (shazow/urllib3535_)

Security

• Pulled in an updated cacert.pem.

• Drop RC4 from the default cipher list. (shazow/urllib3551_)

++++++++++++++++++

API Changes:

  will be raised if they don't.
• Timeouts now apply to read time if Stream=False.
• RequestException is now a subclass of IOError, not RuntimeError.

• Added new method to Session objects: Session.update_request(). This
  method updates a Request object with the data (e.g. cookies) stored on
  the Session.

  method updates and prepares a Request object, and returns the
  corresponding PreparedRequest object.

  This should not be called directly, but improves the subclass interface.
• httplib.IncompleteRead exceptions caused by incorrect chunked encoding
  will now raise a Requests ChunkedEncodingError instead.

pytest -> 3.0.6

3.0.6.dev0

=======================

• pytest no longer generates PendingDeprecationWarning from its own operations, which was introduced by mistake in version 3.0.5 (2118).
  Thanks to nicoddemus for the report and RonnyPfannschmidt_ for the PR.

• pytest no longer recognizes coroutine functions as yield tests (2129).
  Thanks to malinoff for the PR.

• Plugins loaded by the PYTEST_PLUGINS environment variable are now automatically
  considered for assertion rewriting (2185).
  Thanks nicoddemus for the PR.

• Improve error message when pytest.warns fails (2150). The type(s) of the
  expected warnings and the list of caught warnings is added to the
  error message. Thanks lesteve for the PR.

• Fix pytester internal plugin to work correctly with latest versions of
  zope.interface (1989). Thanks nicoddemus for the PR.

• Assert statements of the pytester plugin again benefit from assertion rewriting (1920).
  Thanks RonnyPfannschmidt for the report and nicoddemus_ for the PR.

• Specifying tests with colons like test_foo.py::test_bar for tests in
  subdirectories with ini configuration files now uses the correct ini file
  (2148). Thanks pelme.

• Fail testdir.runpytest().assert_outcomes() explicitly if the pytest
  terminal output it relies on is missing. Thanks to eli-b_ for the PR.

3.0.5

==================

• Add warning when not passing option=value correctly to -o/--override-ini (2105).
  Also improved the help documentation. Thanks to mbukatov for the report and
  lwm_ for the PR.

• Now --confcutdir and --junit-xml are properly validated if they are directories
  and filenames, respectively (2089_ and 2078). Thanks to lwm for the PR.

• Add hint to error message hinting possible missing __init__.py (478). Thanks DuncanBetts.

• More accurately describe when fixture finalization occurs in documentation (687). Thanks DuncanBetts.

• Provide :ref: targets for recwarn.rst so we can use intersphinx referencing.
  Thanks to dupuy_ for the report and lwm_ for the PR.

• In Python 2, use a simple +- ASCII string in the string representation of pytest.approx (for example "4 +- 4.0e-06")
  because it is brittle to handle that in different contexts and representations internally in pytest
  which can result in bugs such as 2111. In Python 3, the representation still uses ± (for example 4 ± 4.0e-06).
  Thanks kerrick-lyft for the report and nicoddemus_ for the PR.

• Using item.Function, item.Module, etc., is now issuing deprecation warnings, prefer
  pytest.Function, pytest.Module, etc., instead (2034).
  Thanks nmundar for the PR.

• Fix error message using approx with complex numbers (2082).
  Thanks adler-j for the report and nicoddemus_ for the PR.

• Fixed false-positives warnings from assertion rewrite hook for modules imported more than
  once by the pytest_plugins mechanism.
  Thanks nicoddemus_ for the PR.

• Remove an internal cache which could cause hooks from conftest.py files in
  sub-directories to be called in other directories incorrectly (2016).
  Thanks d-b-w for the report and nicoddemus_ for the PR.

• Remove internal code meant to support earlier Python 3 versions that produced the side effect
  of leaving None in sys.modules when expressions were evaluated by pytest (for example passing a condition
  as a string to pytest.mark.skipif)(2103).
  Thanks jaraco for the report and nicoddemus_ for the PR.

• Cope gracefully with a .pyc file with no matching .py file (2038). Thanks
  nedbat.

  Thanks nicoddemus for the PR.

• Fixed cyclic reference when pytest.raises is used in context-manager form (1965). Also as a
  result of this fix, sys.exc_info() is left empty in both context-manager and function call usages.
  Previously, sys.exc_info would contain the exception caught by the context manager,
  even when the expected exception occurred.
  Thanks MSeifert04 for the report and the PR.

• Fixed false-positives warnings from assertion rewrite hook for modules that were rewritten but
  were later marked explicitly by pytest.register_assert_rewrite

3.0.3

==================

• The ids argument to parametrize again accepts unicode strings
  in Python 2 (1905).
  Thanks philpep for the report and nicoddemus_ for the PR.

• Assertions are now being rewritten for plugins in development mode
  (pip install -e) (1934).
  Thanks nicoddemus for the PR.

• Fix pkg_resources import error in Jython projects (1853).
  Thanks raquel-ucl for the PR.

• Got rid of AttributeError: 'Module' object has no attribute '_obj' exception
  in Python 3 (1944).
  Thanks axil for the PR.

• Explain a bad scope value passed to fixture declarations or
  a MetaFunc.parametrize() call. Thanks tgoodlet_ for the PR.

• This version includes pluggy-0.4.0, which correctly handles
  VersionConflict errors in plugins (704).
  Thanks nicoddemus for the PR.

3.0.2

==================

• Improve error message when passing non-string ids to pytest.mark.parametrize (1857).
  Thanks okken for the report and nicoddemus_ for the PR.

• Add buffer attribute to stdin stub class pytest.capture.DontReadFromInput
  Thanks joguSD_ for the PR.

• Fix UnicodeEncodeError when string comparison with unicode has failed. (1864)
  Thanks AiOO for the PR.

• pytest_plugins is now handled correctly if defined as a string (as opposed as
  a sequence of strings) when modules are considered for assertion rewriting.
  Due to this bug, much more modules were being rewritten than necessary
  if a test suite uses pytest_plugins to load internal plugins (1888).
  Thanks jaraco for the report and nicoddemus_ for the PR (1891_).

• Do not call tearDown and cleanups when running tests from
  unittest.TestCase subclasses with --pdb
  enabled. This allows proper post mortem debugging for all applications
  which have significant logic in their tearDown machinery (1890). Thanks
  mbyt for the PR.

• Fix use of deprecated getfuncargvalue method in the internal doctest plugin.
  Thanks ViviCoder_ for the report (1898_).
