概述
def a(self):
data = self.get()
if len(data) > 3500:
self.b()
# Bunch of other magic,which is easy to test.
def b(self):
serial.write("\x00\x01\x02")我如何测试b() – 被调用？
import unittest
from mock import patch
def a(n):
if n > 10:
b()
def b():
print "test"
class MyTestCase(unittest.TestCase):
@patch('__main__.b')
def test_b_called(self,mock):
a(11)
self.assertTrue(mock.called)
@patch('__main__.b')
def test_b_not_called(self,mock):
a(10)
self.assertFalse(mock.called)
if __name__ == "__main__":
unittest.main()另见：
> Assert that a method was called in a Python unit test@H_301_15@> Mocking a class: Mock() or patch()?
