Pyhon学习:断言方法
unittest框架的TestCase提供了如下断言方法
| 方法 | 检查 | 版本 |
| assertEqual(a,b) | a==b | |
| assertNotEqual(a,b) | a!=b | |
| assertTrue(x) | bool(x) is True | |
| assertFale(x) | bool(x) is False | |
| assertIs(a,b) | a is b | 3.1 |
| assertNot(a,b) | a is not b | 3.1 |
| assertNone(x) | x is None | 3.1 |
| assertNotNoe(x) | x is not None | 3.1 |
| assertIn(a,b) | a is in b | 3.1 |
| assertNotIn(a,b) | a is not in b | 3.1 |
| assertIsInstance(a,b) | isinstance(a,b) | 3.2 |
| assertNotIsInstance(a,b) | not isinstance(a,b) | 3.2 |
assertEqual(a,b,msg=None)断言第一个参数和第二个参数是否相等，不相等测试失败，msg可选参数，用于定义测试失败时打印的信息
文件isPrime
import unittest
#判断是否为质数
class IsPrime():
def __init__(self,number):
self.number=number
def isPrime(self):
if self.number<=1:
return False
for i in range(2,self.number):
if self.number % i ==0:
return False
return True
class TestIsPrime(unittest.TestCase):
def setup(self):
print('test start')
def test_case(self):
j=IsPrime(5)
print(j.isPrime())
self.assertTrue(j.isPrime(),msg='not is prime')
def teardown(self):
print('test end')
if __name__ =='__main__':
unittest.main()
