Question

pytest -我一直试图在pycharm终端中运行命令以执行pytest脚本。尝试运行代码时，显示错误。 引发ValueError（“选项名称％s已添加”％冲突） ValueError：选项名称{'--browser'}已添加 在此处输入代码来自终端的命令-py.test-v -s test_file.py --browser firefox

**test_file.py**
 import pytest
    def test_command_line_methodA(oneTimeSetUp, setUp):
         print("Running method A")

     def test_command_line_methodB(oneTimeSetUp, setUp):
          print("Running method B")

**conftest.py**
 import pytest

   @pytest.yield_fixture()
       def setUp():
           print("Running method level setUp")
           yield
           print("Running method level tearDown")


    @pytest.yield_fixture(scope="module")
      def oneTimeSetUp(browser, osType):
         print("Running one time setUp")
         if browser == 'firefox':
            print("Running tests on FF")
           else:
             print("Running tests on chrome")
            yield
            print("Running one time tearDown")

            def pytest_addoption(parser):
                 parser.addoption("--browser")
                 parser.addoption("--osType", help="Type of operating 
    system")

            @pytest.fixture(scope="session")
                 def browser(request):
                    return request.config.getoption("--browser")

             @pytest.fixture(scope="session")
                 def osType(request):
                    return request.config.getoption("--osType")

我无法重现您的错误。但是您的缩进与您发布的缩进相同，我认为问题出在此。使用下面的代码，它可以正常工作：

conftest.py ：

import pytest


@pytest.fixture()
def setUp():
    print("Running method level setUp")
    yield
    print("Running method level tearDown")


@pytest.fixture(scope="module")
def oneTimeSetUp(browser, osType):
    print("Running one time setUp")
    if browser == 'firefox':
        print("Running tests on FF")
    else:
        print("Running tests on chrome")
    yield
    print("Running one time tearDown")


def pytest_addoption(parser):
    parser.addoption("--browser")
    parser.addoption("--osType", help="Type of operating system")


@pytest.fixture(scope="session")
def browser(request):
    return request.config.getoption("--browser")


@pytest.fixture(scope="session")
def osType(request):
    return request.config.getoption("--osType")

test_file.py ：

import pytest
def test_command_line_methodA(oneTimeSetUp, setUp):
    print("Running method A")


def test_command_line_methodB(oneTimeSetUp, setUp):
    print("Running method B")

我也将yield_fixture更改为fixture，因为它是deprecated

ValueError：选项名称{'--browser'}已添加
