读取文件中的鼻子测试参数,尤其是@attr [英] Read nose tests arguments in a file especially @attr
问题描述
如果我调用测试脚本,请说
If I invoke a test script say
nosetests -a tag1='one'
是否可以在我的脚本中打印tag1
的用户输入?
is there a way to print the user input of tag1
in my script?
@attr(tag1=['one', 'two', 'three', 'four'])
def test_real_logic(self):
#how to print the user input here
推荐答案
并非没有痛苦. self.test_real_logic.tag1
应该为您提供该函数附带的所有属性.它们以字典的形式存储在测试功能的__dict__
属性中.
对于test_real_logic.tag1
,它将是['one', 'two', 'three', 'four'].
Not without some pain. self.test_real_logic.tag1
should give you all the attributes attached to the function. They are stored as a dictionary within __dict__
attribute of the test function.
For test_real_logic.tag1
it would be ['one', 'two', 'three', 'four'].
如果您不想对函数名称进行硬编码,则cad尝试通过执行以下操作来提取字典:
If you do not want to hard code function name, you cad try extract the dictionary by doing something like:
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,您将不得不遍历本地属性,并将其与系统参数进行比较以进行匹配,并打印常见的属性,这与属性插件已执行的操作类似.或者,您可以稍微修改现有的attrib
插件方法validateAttrib
,以便将匹配的属性添加到属性列表中,如下所示(在Lib/site-packages/nose/plugins/attrib.py
中):
Now you would have to iterate over local attributes and compare them with the system arguments for a match and print the attributes that are common, similar to what attribute plugin already does. Or you can slightly modify the existing attrib
plugin method validateAttrib
so that it adds a matching attribute to the list of attributes, something like this (in Lib/site-packages/nose/plugins/attrib.py
):
def validateAttrib(self, method, cls = None):
"""Verify whether a method has the required attributes
The method is considered a match if it matches all attributes
for any attribute group.
."""
# TODO: is there a need for case-sensitive value comparison?
any = False
for group in self.attribs:
match = True
for key, value in group:
attr = get_method_attr(method, cls, key)
if callable(value):
if not value(key, method, cls):
match = False
break
elif value is True:
# value must exist and be True
if not bool(attr):
match = False
break
elif value is False:
# value must not exist or be False
if bool(attr):
match = False
break
elif type(attr) in (list, tuple):
# value must be found in the list attribute
if not str(value).lower() in [str(x).lower()
for x in attr]:
match = False
break
else:
# value must match, convert to string and compare
if (value != attr
and str(value).lower() != str(attr).lower()):
match = False
break
any = any or match
#remember match
if match:
matched_key = key
matched_value = value
if any:
method.__dict__['matched_key'] = matched_key
method.__dict__['matched_value'] = matched_value
# not True because we don't want to FORCE the selection of the
# item, only say that it is acceptable
return None
return False
这样,您的self.test_real_logic
将具有两个附加属性matched_key=tag1
和matched_value=one
,您可以像tag1
属性一样访问它们.
This way your self.test_real_logic
will have two additional attributes matched_key=tag1
and matched_value=one
that you can access similarly as tag1
attribute.
