Python Read nose测试文件中的参数,尤其是@attr
如果我调用一个测试脚本Python Read nose测试文件中的参数,尤其是@attr,python,attr,nose,nosetests,Python,Attr,Nose,Nosetests,如果我调用一个测试脚本 nosetests -a tag1='one' 有没有办法在我的脚本中打印用户输入的tag1 @attr(tag1=['one', 'two', 'three', 'four']) def test_real_logic(self): #how to print the user input here 不是没有痛苦self.test\u real\u logic.tag1应该为您提供附加到函数的所有属性。它们作为字典存储在测试函数的\uuuu dict\uuu
nosetests -a tag1='one'
有没有办法在我的脚本中打印用户输入的tag1
@attr(tag1=['one', 'two', 'three', 'four'])
def test_real_logic(self):
#how to print the user input here
不是没有痛苦
self.test\u real\u logic.tag1
应该为您提供附加到函数的所有属性。它们作为字典存储在测试函数的\uuuu dict\uuu
属性中。
对于test\u real\u logic.tag1
来说,它应该是['1'、'2'、'3'、'4']。
如果不想硬编码函数名,请尝试通过执行以下操作来提取字典:
import sys
def get_attr_dict(cls):
# cls here is either unittest.TestCase or whatever stores your test
return getattr(cls, sys._getframe().f_back.f_code.co_name).__dict__
现在,您必须迭代本地属性,并将它们与匹配的系统参数进行比较,然后打印常见的属性,这与属性插件已经做的类似。或者您可以稍微修改现有的attrib
plugin方法validateAttrib
,以便在属性列表中添加一个匹配的属性,如下所示(在Lib/site packages/nose/plugins/attrib.py
中):
这样,您的
self.test\u real\u logic
将有两个附加属性matched\u key=tag1
和matched\u value=one
,您可以像tag1
属性一样访问这些属性。我能够以pythonic方式读取值,即从sys.argv读取并解析tag1,有没有办法在nose函数中执行此操作?
