例如，考虑以下内容：
import pytest
@pytest.mark.my_marker(foo='bar')
def test_001():
pass
def test_002():
pass
@pytest.mark.my_marker(foo='bar', cat='dog')
def test_003():
pass
py.test -s -m "my_marker(cat='dog')"
沙拉德我能够合理地接近这一点： conftest.py 测试棒 输出
#不指定任何标记 py.test-vs test_bar.py
#指定foo=bar py.test-vs-m“{'my_marker'：{'foo'：'bar'}”test_bar.py
