本篇博客比较下 parametrize 中 参数为 True 和 False 时，不同 的表现。

# File  : test_demo_11.py
# IDE   : PyCharm

import pytest

@pytest.fixture(params=['a', 'b', 'c'])
def fixture_and_paramterize(request):
    print('\n执行参数{}'.format(request.param))
    return request.param

# indirect=False
@pytest.mark.parametrize('fixture_and_paramterize', ['d', 'e', 'f'], indirect=False)
def test_fixture_and_paramterize(fixture_and_paramterize):
    print('indirect=False,参数为{}'.format(fixture_and_paramterize))

# indirect=False
@pytest.mark.parametrize('fixture_and_paramterize', ['d', 'e', 'f'], indirect=True)
def test_fixture_and_paramterize_2(fixture_and_paramterize):
    print('indirect=True,参数为{}'.format(fixture_and_paramterize))

执行代码：

当 indirect=True 时，argnames 参数被当成函数执行，且 argvalues 值被当成函数中的参数传参。 

当 indirect=True 时，argnames 参数被当成普通变量
