Pytest运行所有测试两次，并将结果与mock和real进行比较

import pytest
from unittest import mock

@pytest.fixture
def mock_dependency():
    # 创建一个模拟对象
    mock_obj = mock.Mock()
    # 设置模拟对象的行为
    mock_obj.some_method.return_value = "mocked result"
    return mock_obj

def test_something(mock_dependency):
    # 使用模拟对象进行测试
    result = mock_dependency.some_method()
    assert result == "mocked result"

def test_run_tests_twice(mock_dependency):
    # 运行所有的测试用例两次
    for _ in range(2):
        pytest.main(["-v"])
        # 在每次运行后，将结果与模拟对象和真实对象进行比较
        assert mock_dependency.some_method.call_count == 1
