我用一个新的更简单的假设置重新创建了这个问题。在
我有一个需要pytest的命令行变量的框架。这个变量叫做environment,但是当我试图访问这个变量时,我得到一个AttributeError:“module”对象没有属性“config”。在
以下是我的测试设置:
我知道py.测试按此顺序加载:
我想我遇到了一个问题,当我加载内部conftest.py我试图导入框架。当我导入框架时,它试图访问py.测试变量。这个变量,即使pytest已经在我的outer的pytest_addoption()部分看到了它-conftest.py,未准备好在pytest中使用。在
外部竞赛内容:
# content of conftest.py
import pytest
def pytest_addoption(parser):
print("First")
parser.addoption("--cmdopt", action="store", default="type1",
help="my option: type1 or type2")
@pytest.fixture
def cmdopt(request):
return request.config.getoption("cmdopt")

^{pr2}$内部内容conftest.py公司名称:
import pytest

试验内容_样品.py公司名称:
# content of test_sample.py
def test_answer(cmdopt):
if cmdopt == "type1":
print ("first")
elif cmdopt == "type2":
print ("second")
assert 0 # to see what was printed
我在testing/文件夹中运行以下命令: py.测试-q—cmdopt=类型2
我收到以下错误:

有没有一种好方法可以使用依赖于pytest命令行变量的外部框架?在
理想情况下,您应该有fixture从框架中为您提供对象,例如一个用户实例。在
这些fixture可以receivefixture,
cmdopt
fixture,然后可以将该值传递给init方法或工厂函数。在例如
然后在你的测试中
^{pr2}$您只需将变量添加到模块中即可框架.py,将框架模块导入外部conftest.py并在cmdopt方法下设置此变量。在
代码输入框架.py公司名称:
外部代码conftest.py公司名称:
^{pr2}$您可以做的第二件事是向环境类添加变量并对其进行操作。如果在获取或设置此变量时需要更多的逻辑,则可以在环境类中始终使用@property和setter。在
