hypothesis用于创建单元测试的Python库
安装
pip install hypothesis
应用:
利用hypothesis生成测试数据
test.py
def add(a, b): return a + b
使用随机数生成测试数据
test1.py
import unittest from random import randint from test import add class AddTest(unittest.TestCase): def test_case1(self): for i in range(10): a=randint(-32768,32767) b=randint(-32768,32767) print(a,b) c1=a+b c2=add(a,b) self.assertEqual(c1,c2) if __name__=="__main__": unittest.main()
test2.py
import unittest from hypothesis import given, settings import hypothesis.strategies as st from test import add class AddTest(unittest.TestCase): @settings(max_examples=10) @given(a=st.integers(), b=st.integers()) def test_case(self, a, b): print("a->", a) print("b->", b) c1 = a + b c2 = add(a, b) self.assertEqual(c1, c2) if __name__ == '__main__': unittest.main()
通过@given()
装饰测试用例
调用strategies
模块下面的 integers()
方法生成随机的测试数
在@setting()
装饰器中通过max_examples
用来控制随机数的个数
生成email
import unittest from hypothesis import given, settings import hypothesis.strategies as st class AddTest(unittest.TestCase): @settings(max_examples=20) @given(o=st.emails()) def test_case(self,o): print(o) if __name__ == '__main__': unittest.main()
