fixture 'a' not found

I wrote a testcase like this, but it doesn't work.

import pytest


@pytest.fixture()
def my_fixture():
    print('begin')
    print('#####################################')


class TestA():

    # @pytest.mark.usefixtures('my_fixture')
    def test_a(self, my_fixture, a):
        print("{}".format(a))


if __name__ == '__main__':
    pytest.main()

the raise error:

E       fixture 'a' not found
>       available fixtures: cache, capfd, capfdbinary, caplog, capsys, capsysbinary, doctest_namespace, extra, include_metadata_in_junit_xml, login_and_exit, metadata, monkeypatch, my_fixture, pytestconfig, record_property, record_testsuite_property, record_xml_attribute, recwarn, tmp_path, tmp_path_factory, tmpdir, tmpdir_factory
>       use 'pytest --fixtures [testpath]' for help on them.

I don't know why......

If you uncomment decorator above test_a and remove parameters it will work. Also you can remove redundant parentheses from class definition and fixture decorator:

import pytest


@pytest.fixture
def my_fixture():
    print('Inside fixture my_fixture.')


@pytest.fixture
def a():
    print('Inside fixture a . Returning value 3 for a')
    return 3


class Test:

    @pytest.mark.usefixtures('my_fixture', 'a')
    def test_a(self, a):
        print("Inside test. Argument has value: {}".format(a))


if __name__ == '__main__':
    pytest.main()
