-
-* ``joedoe`` is invited to the ``pytest-xyz-admin`` team;
-
-* After accepting the invitation, ``joedoe`` transfers the repository from its

-  the old to the new location automatically).
-
-* ``joedoe`` is free to add any other collaborators to the

+* ``joedoe`` transfers repository ownership to ``pytest-dev`` administrator ``calvin``.

 How to release pytest
 --------------------------------------------
 
-Note: this assumes you have already registered on pypi.
+.. important::
 
-0. create the branch release-VERSION
-   use features as base for minor/major releases
-   and master as base for bugfix releases
+    pytest releases must be prepared on **Linux** because the docs and examples expect
+    to be executed in that platform.
 
-1. Bump version numbers in _pytest/__init__.py (setup.py reads it)
+#. Install development dependencies in a virtual environment with::
 
-2. Check and finalize CHANGELOG
+    pip3 install -r tasks/requirements.txt
 
-3. Write doc/en/announce/release-VERSION.txt and include
-   it in doc/en/announce/index.txt::
+#. Create a branch ``release-X.Y.Z`` with the version for the release.
 
-        git log 2.8.2..HEAD --format='%aN' | sort -u # lists the names of authors involved
+   * **patch releases**: from the latest ``master``;
 
-4. Use devpi for uploading a release tarball to a staging area::
+   * **minor releases**: from the latest ``features``; then merge with the latest ``master``;
 
-     devpi use https://devpi.net/USER/dev
-     devpi upload --formats sdist,bdist_wheel
+   Ensure your are in a clean work tree.
 
-5. Run from multiple machines::
+#. Generate docs, changelog, announcements and upload a package to
+   your ``devpi`` staging server::
 
-     devpi use https://devpi.net/USER/dev
-     devpi test pytest==VERSION
+     invoke generate.pre_release <VERSION> <DEVPI USER> --password <DEVPI PASSWORD>
 
-6. Check that tests pass for relevant combinations with::
+   If ``--password`` is not given, it is assumed the user is already logged in ``devpi``.
+   If you don't have an account, please ask for one.
+
+#. Open a PR for this branch targeting ``master``.
+
+#. Test the package
+
+   * **Manual method**
+
+     Run from multiple machines::
+
+       devpi use https://devpi.net/USER/dev
+       devpi test pytest==VERSION
+
+     Check that tests pass for relevant combinations with::
 
        devpi list pytest
 
-   or look at failures with "devpi list -f pytest".
+   * **CI servers**
 
-7. Regenerate the docs examples using tox, and check for regressions::
+     Configure a repository as per-instructions on
+     devpi-cloud-test_ to test the package on Travis_ and AppVeyor_.
+     All test environments should pass.
 
-      tox -e regen
-      git diff
+#. Publish to PyPI::
 
+      invoke generate.publish_release <VERSION> <DEVPI USER> <PYPI_NAME>
 
-8. Build the docs, you need a virtualenv with py and sphinx
-   installed::
+   where PYPI_NAME is the name of pypi.python.org as configured in your ``~/.pypirc``
+   file `for devpi <http://doc.devpi.net/latest/quickstart-releaseprocess.html?highlight=pypirc#devpi-push-releasing-to-an-external-index>`_.
 
-      cd doc/en      
-      make html
+#. After a minor/major release, merge ``features`` into ``master`` and push (or open a PR).
 
-   Commit any changes before tagging the release.
-
-9. Tag the release::
-
-      git tag VERSION
-      git push
-
-10. Upload the docs using doc/en/Makefile::
-
-      cd doc/en
-      make install  # or "installall" if you have LaTeX installed for PDF
-
-    This requires ssh-login permission on pytest.org because it uses
-    rsync.
-    Note that the ``install`` target of ``doc/en/Makefile`` defines where the
-    rsync goes to, typically to the "latest" section of pytest.org.
-
-    If you are making a minor release (e.g. 5.4), you also need to manually
-    create a symlink for "latest"::
-
-       ssh pytest-dev@pytest.org
-       ln -s 5.4 latest
-
-    Browse to pytest.org to verify.
-
-11. Publish to pypi::
-
-      devpi push pytest-VERSION pypi:NAME
-
-    where NAME is the name of pypi.python.org as configured in your ``~/.pypirc``
-    file `for devpi <http://doc.devpi.net/latest/quickstart-releaseprocess.html?highlight=pypirc#devpi-push-releasing-to-an-external-index>`_.

-
-    - pytest-dev
-    - testing-in-python
-    - python-announce-list@python.org
-
-
-13. **after the release** Bump the version number in ``_pytest/__init__.py``,
-    to the next Minor release version (i.e. if you released ``pytest-2.8.0``,
-    set it to ``pytest-2.9.0.dev1``).

-Like monkeypatch.replace but sets a mock-like call recorder:
-
-    recorder = monkeypatch.function("os.path.abspath")
-    recorder.set_return("/hello")
-    os.path.abspath("hello")
-    call, = recorder.calls
-    assert call.args.path == "hello"
-    assert call.returned == "/hello"
-    ...
-
-Unlike mock, "args.path" acts on the parsed auto-spec'ed ``os.path.abspath``
-so it's independent from if the client side called "os.path.abspath(path=...)"
-or "os.path.abspath('positional')".
-
-
-refine parametrize API
--------------------------------------------------------------
-tags: critical feature 
-
-extend metafunc.parametrize to directly support indirection, example:
-
-    def setupdb(request, config):
-        # setup "resource" based on test request and the values passed 
-        # in to parametrize.  setupfunc is called for each such value.
-        # you may use request.addfinalizer() or request.cached_setup ...
-        return dynamic_setup_database(val)
-
-    @pytest.mark.parametrize("db", ["pg", "mysql"], setupfunc=setupdb)
-    def test_heavy_functional_test(db):
-        ...
-
-There would be no need to write or explain funcarg factories and
-their special __ syntax.
-
-The examples and improvements should also show how to put the parametrize
-decorator to a class, to a module or even to a directory.  For the directory
-part a conftest.py content like this::
-
-    pytestmark = [
-        @pytest.mark.parametrize_setup("db", ...),
-    ]
-
-probably makes sense in order to keep the declarative nature.   This mirrors
-the marker-mechanism with respect to a test module but puts it to a directory
-scale.
-
-When doing larger scoped parametrization it probably becomes necessary
-to allow parametrization to be ignored if the according parameter is not
-used (currently any parametrized argument that is not present in a function will cause a ValueError). Example:
-
-        @pytest.mark.parametrize("db", ..., mustmatch=False)
-
-means to not raise an error but simply ignore the parametrization
-if the signature of a decorated function does not match. XXX is it
-not sufficient to always allow non-matches?
-
-
-allow parametrized attributes on classes
--------------------------------------------------- 
-
-tags: wish 2.4
-
-example:
-
-    @pytest.mark.parametrize_attr("db", setupfunc, [1,2,3], scope="class")
-    @pytest.mark.parametrize_attr("tmp", setupfunc, scope="...")
-    class TestMe:
-        def test_hello(self):
-            access self.db ...
-
-this would run the test_hello() function three times with three
-different values for self.db. This could also work with unittest/nose
-style tests, i.e. it leverages existing test suites without needing
-to rewrite them. Together with the previously mentioned setup_test()
-maybe the setupfunc could be omitted?

-etc. Idea is to allow Python expressions which can operate
-on common spellings for operating systems and python
-interpreter versions.
-
-pytest.mark.xfail signature change
--------------------------------------------------------
-tags: feature 
-
-change to pytest.mark.xfail(reason, (optional)condition)
-to better implement the word meaning.  It also signals
-better that we always have some kind of an implementation
-reason that can be formualated.
-Compatibility? how to introduce a new name/keep compat?
-
-allow to non-intrusively apply skipfs/xfail/marks
----------------------------------------------------
-tags: feature 
-
-use case: mark a module or directory structures
-to be skipped on certain platforms (i.e. no import
-attempt will be made).
-
-consider introducing a hook/mechanism that allows to apply marks
-from conftests or plugins. (See extended parametrization)
-
-
-explicit referencing of conftest.py files
------------------------------------------
-tags: feature 
-
-allow to name conftest.py files (in sub directories) that should
-be imported early, as to include command line options.
-
-improve central pytest ini file
--------------------------------
-tags: feature 
-
-introduce more declarative configuration options:
-- (to-be-collected test directories)
-- required plugins
-- test func/class/file matching patterns
-- skip/xfail (non-intrusive)
-- pytest.ini and tox.ini and setup.cfg configuration in the same file
-
-new documentation
-----------------------------------
-tags: feature 
-
-- logo pytest
-- examples for unittest or functional testing
-- resource management for functional testing
-- patterns: page object
-
-have imported module mismatch honour relative paths
---------------------------------------------------------
-tags: bug 
-
-With 1.1.1 pytest fails at least on windows if an import
-is relative and compared against an absolute conftest.py
-path. Normalize.
-
-consider globals: pytest.ensuretemp and config
---------------------------------------------------------------
-tags: experimental-wish 
-
-consider deprecating pytest.ensuretemp and pytest.config
-to further reduce pytest globality.  Also consider
-having pytest.config and ensuretemp coming from
-a plugin rather than being there from the start.
-
-
-consider pytest_addsyspath hook
------------------------------------------
-tags: wish
-
-pytest could call a new pytest_addsyspath() in order to systematically
-allow manipulation of sys.path and to inhibit it via --no-addsyspath
-in order to more easily run against installed packages.
-
-Alternatively it could also be done via the config object
-and pytest_configure.
-
-
-
-deprecate global pytest.config usage
-----------------------------------------------------------------
-tags: feature 
-
-pytest.ensuretemp and pytest.config are probably the last
-objects containing global state.  Often using them is not
-necessary.  This is about trying to get rid of them, i.e.
-deprecating them and checking with PyPy's usages as well
-as others.
-
-remove deprecated bits in collect.py
--------------------------------------------------------------------
-tags: feature 
-
-In an effort to further simplify code, review and remove deprecated bits
-in collect.py.  Probably good:
-- inline consider_file/dir methods, no need to have them
-  subclass-overridable because of hooks
-
-implement fslayout decorator
----------------------------------
-tags: feature 
-
-Improve the way how tests can work with pre-made examples,
-keeping the layout close to the test function:
-
-@pytest.mark.fslayout("""
-    conftest.py:
-        #  empty
-    tests/
-        test_%(NAME)s:  # becomes test_run1.py
-            def test_function(self):
-                pass
-""")
-def test_run(pytester, fslayout):
-    p = fslayout.findone("test_*.py")
-    result = pytester.runpytest(p)
-    assert result.ret == 0
-    assert result.passed == 1
-
-Another idea is to allow to define a full scenario including the run
-in one content string::
-
-    runscenario("""
-        test_{TESTNAME}.py:
-            import pytest
-            @pytest.mark.xfail
-            def test_that_fails():
-                assert 0
-
-            @pytest.mark.skipif("True")
-            def test_hello():
-                pass
-
-        conftest.py:
-            import pytest
-            def pytest_runsetup_setup(item):
-                pytest.skip("abc")
-
-        runpytest -rsxX
-        *SKIP*{TESTNAME}*
-        *1 skipped* 
-    """)
-
-This could be run with at least three different ways to invoke pytest:
-through the shell, through "python -m pytest" and inlined. As inlined
-would be the fastest it could be run first (or "--fast" mode).
-
-
-Create isolate plugin
----------------------
-tags: feature
-
-The idea is that you can e.g. import modules in a test and afterwards
-sys.modules, sys.meta_path etc would be reverted.  It can go further
-then just importing however, e.g. current working directory, file
-descriptors, ...
-
-This would probably be done by marking::
-
-    @pytest.mark.isolate(importing=True, cwd=True, fds=False)
-    def test_foo():
-        ...
-
-With the possibility of doing this globally in an ini-file.
-
-
-fnmatch for test names
-----------------------
-tags: feature-wish
-
-various testsuites use suffixes instead of prefixes for test classes
-also it lends itself to bdd style test names::
-
-    class UserBehaviour:
-        def anonymous_should_not_have_inbox(user):
-            ...
-        def registred_should_have_inbox(user):
-            ..
-
-using the following in pytest.ini::
-
-    [pytest]
-    python_classes = Test *Behaviour *Test
-    python_functions = test *_should_*
-
-
-mechanism for running named parts of tests with different reporting behaviour
-------------------------------------------------------------------------------
-tags: feature-wish-incomplete
-
-a few use-cases come to mind:
-
-* fail assertions and record that without stopping a complete test
-
-  * this is in particular hepfull if a small bit of a test is known to fail/xfail::
-
-    def test_fun():
-        with pytest.section('fdcheck, marks=pytest.mark.xfail_if(...)):
-            breaks_on_windows()
-
-* divide functional/acceptance tests into sections
-* provide a different mechanism for generators, maybe something like::
-
-    def pytest_runtest_call(item)
-        if not generator:
-            ...
-        prepare_check = GeneratorCheckprepare()
-
-        gen = item.obj(**fixtures)
-        for check in gen
-            id, call = prepare_check(check)
-            # bubble should only prevent exception propagation after a failure
-            # the whole test should still fail
-            # there might be need for a lower level api and taking custom markers into account
-            with pytest.section(id, bubble=False):
-                call()

-# Hi There!
-# You may be wondering what this giant blob of binary data here is, you might
-# even be worried that we're up to something nefarious (good for you for being
-# paranoid!). This is a base64 encoding of a zip file, this zip file contains
-# a fully functional basic pytest script.
-#
-# Pytest is a thing that tests packages, pytest itself is a package that some-
-# one might want to install, especially if they're looking to run tests inside
-# some package they want to install. Pytest has a lot of code to collect and
-# execute tests, and other such sort of "tribal knowledge" that has been en-
-# coded in its code base. Because of this we basically include a basic copy
-# of pytest inside this blob. We do this  because it let's you as a maintainer
-# or application developer who wants people who don't deal with python much to
-# easily run tests without installing the complete pytest package.
-#
-# If you're wondering how this is created: you can create it yourself if you
-# have a complete pytest installation by using this command on the command-
-# line: ``py.test --genscript=runtests.py``.

+pytest-3.0.0
+============
+
+The pytest team is proud to announce the 3.0.0 release!
+
+pytest is a mature Python testing tool with more than a 1600 tests
+against itself, passing on many different interpreters and platforms.
+
+This release contains a lot of bugs fixes and improvements, and much of
+the work done on it was possible because of the 2016 Sprint[1], which
+was funded by an indiegogo campaign which raised over US$12,000 with 
+nearly 100 backers. 
+
+There's a "What's new in pytest 3.0" [2] blog post highlighting the 
+major features in this release.
+
+To see the complete changelog and documentation, please visit:
+
+    http://docs.pytest.org
+
+As usual, you can upgrade from pypi via:
+
+    pip install -U pytest
+
