0.3.0 found my fixtures; 1.1.2 cannot.

[nedbat]

Describe the bug
The main branch of https://github.com/nedbat/scriv uses pylint-pytest 0.3.0. Running "tox -e quality" succeeds.

The nedbat/no-travis branch updated dependencies, and now uses pylint-pytest 1.1.2. Pylint now fails with:

When I run the suggested command, I don't see any indication of a problem, or how to fix it:

cache
    Return a cache object that can persist state between testing sessions.

    cache.get(key, default)
    cache.set(key, value)

    Keys must be ``/`` separated strings, where the first part is usually the
    name of your plugin or application to avoid clashes with other cache users.

    Values can be any object handled by the json stdlib module.

capsys
    Enable text capturing of writes to ``sys.stdout`` and ``sys.stderr``.

    The captured output is made available via ``capsys.readouterr()`` method
    calls, which return a ``(out, err)`` namedtuple.
    ``out`` and ``err`` will be ``text`` objects.

capsysbinary
    Enable bytes capturing of writes to ``sys.stdout`` and ``sys.stderr``.

    The captured output is made available via ``capsysbinary.readouterr()``
    method calls, which return a ``(out, err)`` namedtuple.
    ``out`` and ``err`` will be ``bytes`` objects.

capfd
    Enable text capturing of writes to file descriptors ``1`` and ``2``.

    The captured output is made available via ``capfd.readouterr()`` method
    calls, which return a ``(out, err)`` namedtuple.
    ``out`` and ``err`` will be ``text`` objects.

capfdbinary
    Enable bytes capturing of writes to file descriptors ``1`` and ``2``.

    The captured output is made available via ``capfd.readouterr()`` method
    calls, which return a ``(out, err)`` namedtuple.
    ``out`` and ``err`` will be ``byte`` objects.

doctest_namespace [session scope]
    Fixture that returns a :py:class:`dict` that will be injected into the
    namespace of doctests.

pytestconfig [session scope]
    Session-scoped fixture that returns the :class:`_pytest.config.Config` object.

    Example::

        def test_foo(pytestconfig):
            if pytestconfig.getoption("verbose") > 0:
                ...

record_property
    Add extra properties to the calling test.

    User properties become part of the test report and are available to the
    configured reporters, like JUnit XML.

    The fixture is callable with ``name, value``. The value is automatically
    XML-encoded.

    Example::

        def test_function(record_property):
            record_property("example_key", 1)

record_xml_attribute
    Add extra xml attributes to the tag for the calling test.

    The fixture is callable with ``name, value``. The value is
    automatically XML-encoded.

record_testsuite_property [session scope]
    Record a new ``<property>`` tag as child of the root ``<testsuite>``.

    This is suitable to writing global information regarding the entire test
    suite, and is compatible with ``xunit2`` JUnit family.

    This is a ``session``-scoped fixture which is called with ``(name, value)``. Example:

    .. code-block:: python

        def test_foo(record_testsuite_property):
            record_testsuite_property("ARCH", "PPC")
            record_testsuite_property("STORAGE_TYPE", "CEPH")

    ``name`` must be a string, ``value`` will be converted to a string and properly xml-escaped.

    .. warning::

        Currently this fixture **does not work** with the
        `pytest-xdist <https://github.com/pytest-dev/pytest-xdist>`__ plugin. See issue
        `#7767 <https://github.com/pytest-dev/pytest/issues/7767>`__ for details.

caplog
    Access and control log capturing.

    Captured logs are available through the following properties/methods::

    * caplog.messages        -> list of format-interpolated log messages
    * caplog.text            -> string containing formatted log output
    * caplog.records         -> list of logging.LogRecord instances
    * caplog.record_tuples   -> list of (logger_name, level, message) tuples
    * caplog.clear()         -> clear captured records and formatted log output string

monkeypatch
    A convenient fixture for monkey-patching.

    The fixture provides these methods to modify objects, dictionaries or
    os.environ::

        monkeypatch.setattr(obj, name, value, raising=True)
        monkeypatch.delattr(obj, name, raising=True)
        monkeypatch.setitem(mapping, name, value)
        monkeypatch.delitem(obj, name, raising=True)
        monkeypatch.setenv(name, value, prepend=False)
        monkeypatch.delenv(name, raising=True)
        monkeypatch.syspath_prepend(path)
        monkeypatch.chdir(path)

    All modifications will be undone after the requesting test function or
    fixture has finished. The ``raising`` parameter determines if a KeyError
    or AttributeError will be raised if the set/deletion operation has no target.

recwarn
    Return a :class:`WarningsRecorder` instance that records all warnings emitted by test functions.

    See http://docs.python.org/library/warnings.html for information
    on warning categories.

tmpdir_factory [session scope]
    Return a :class:`_pytest.tmpdir.TempdirFactory` instance for the test session.

tmp_path_factory [session scope]
    Return a :class:`_pytest.tmpdir.TempPathFactory` instance for the test session.

tmpdir
    Return a temporary directory path object which is unique to each test
    function invocation, created as a sub directory of the base temporary
    directory.

    By default, a new base temporary directory is created each test session,
    and old bases are removed after 3 sessions, to aid in debugging. If
    ``--basetemp`` is used then it is cleared each session. See :ref:`base
    temporary directory`.

    The returned object is a `py.path.local`_ path object.

    .. _`py.path.local`: https://py.readthedocs.io/en/latest/path.html

tmp_path
    Return a temporary directory path object which is unique to each test
    function invocation, created as a sub directory of the base temporary
    directory.

    By default, a new base temporary directory is created each test session,
    and old bases are removed after 3 sessions, to aid in debugging. If
    ``--basetemp`` is used then it is cleared each session. See :ref:`base
    temporary directory`.

    The returned object is a :class:`pathlib.Path` object.


------------------------------------------------------------ fixtures defined from pytest_mock.plugin -------------------------------------------------------------
class_mocker [class scope]
    Return an object that has the same interface to the `mock` module, but
    takes care of automatically undoing all patches after each test method.

mocker
    Return an object that has the same interface to the `mock` module, but
    takes care of automatically undoing all patches after each test method.

module_mocker [module scope]
    Return an object that has the same interface to the `mock` module, but
    takes care of automatically undoing all patches after each test method.

package_mocker [package scope]
    Return an object that has the same interface to the `mock` module, but
    takes care of automatically undoing all patches after each test method.

session_mocker [session scope]
    Return an object that has the same interface to the `mock` module, but
    takes care of automatically undoing all patches after each test method.


-------------------------------------------------------------- fixtures defined from tests.conftest ---------------------------------------------------------------
changelog_d
    Make a changelog.d directory, and return a Path() to it.

fake_run_command
    Replace gitinfo.run_command with a fake.

    Get a FakeGit to use in tests.

temp_dir
    Make and change into the tmpdir directory, as a Path.

cli_invoke
    Produce a function to invoke the Scriv cli with click.CliRunner.

    The test will run in a temp directory.

Why does the newer version fail to find fixtures? What am I supposed to do to fix it? Thanks.
