我一直在用 PyDev 成功地进行鼻子测试,并想尝试一下nose2。
所以我安装了它
pip install nose2
将示例代码从http://nose2.info/复制/粘贴到一个名为“test_script_with_nose2”的新模块中:
from nose2.compat import unittest
from nose2.tools import params
def tests_can_be_functions():
assert True
def tests_can_be_generators():
def check(val):
assert val == val, "Identity failure!"
for i in range(1, 4):
yield check, i
@params(1, 2, 3)
def tests_can_take_parameters(p):
assert p < 4, "How'd that get here?"
class TestsCanBeUnittestTestCases(unittest.TestCase):
def setUp(self):
self.x = 1
def test_one(self):
self.assertEqual(self.x, 1)
class TestsCanBePlainClasses(object):
def setUp(self):
self.me_too = 1
def test(self):
assert self.me_too == 1, "Not me too?"
但我得到这个错误
======================================================================

我在pydev中选择了nose作为单元测试运行器,但也许它需要一个新的nose2运行器?如果是这样,有人知道该怎么做吗?还是我在这里遗漏了一些微不足道的东西?
