Python之测试
测试函数功能：def average(values):
"""Computes.
>>> print(average())
5.0
"""
return sum(values)/len(values)
import doctest
doctest.testmod()
结果;
TestResults(failed=0, attempted=1)
单元测试demo:
import unittest
def average(values):
"""Computes.
>>> print(average())
5.0
"""
return sum(values)/len(values)
class TestStatisticalFunctions(unittest.TestCase):
def test_average(self):
self.assertEqual(average(), 40.0)
self.assertEqual(round(average(), 1), 4.3)
self.assertRaises(ZeroDivisionError, average, [])
self.assertRaises(TypeError, average, 20, 30, 70)
unittest.main() # Calling from the command line invokes all tests
执行结果如下;
