python测试设置测试描述
我正在用python动态(必须)创建测试,以便使用nosetests运行,如下所示:python测试设置测试描述,python,nosetests,Python,Nosetests,我正在用python动态(必须)创建测试,以便使用nosetests运行,如下所示: def my_verification_method(param): """ description """ assert param>0, "something bad..." def test_apps(): """ make tests on the fly """ param1 = 1 my_verification_method.__doc__ = "t
def my_verification_method(param):
""" description """
assert param>0, "something bad..."
def test_apps():
""" make tests on the fly """
param1 = 1
my_verification_method.__doc__ = "test with param=%i" % param1
yield my_verification_method, param1
param1 = 2
my_verification_method.__doc__ = "test with param=%i" % param1
yield my_verification_method, param1
问题在于,鼻子测试显示:
make tests on the fly ... ok
make tests on the fly ... ok
这不是我想要的。我希望测试的输出显示:
test with param=1 ... ok
test with param=2 ... ok
有什么想法吗?这里是如何做你想做的事情,但是它将绕过
产生测试生成。本质上,您可以使用下面的populate()
方法动态填充一个空白的unittest.TestCase
:
from unittest import TestCase
from nose.tools import istest
def my_verification_method(param):
""" description """
print "this is param=", param
assert param > 0, "something bad..."
def method_name(param):
""" this is how you name the tests from param values """
return "test_with_param(%i)" % param
def doc_name(param):
""" this is how you generate doc strings from param values """
return "test with param=%i" % param
def _create(param):
""" Helper method to make functions on the fly """
@istest
def func_name(self):
my_verification_method(param)
return func_name
def populate(cls, params):
""" Helper method that injects tests to the TestCase class """
for param in params:
_method = _create(param)
_method.__name__ = method_name(param)
_method.__doc__ = doc_name(param)
setattr(cls, _method.__name__, _method)
class AppsTest(TestCase):
""" TestCase Container """
pass
test_params = [-1, 1, 2]
populate(AppsTest, test_params)
你应该得到:
$ nosetests doc_test.py -v
test with param=-1 ... FAIL
test with param=1 ... ok
test with param=2 ... ok
为了正确地填充类,您需要更改方法名和文档字符串
EDIT:func\u name应该有self
作为参数,因为它现在是一个类方法。nosetest生成器功能通常会显示您通过的参数,但不确定为什么您的代码没有通过。非常感谢。这正是我的意思。
