pytest.mark.parametrize装饰器可以实现测试用例参数化
parametrizing
1.这里是一个实现检查一定的输入和期望输出测试功能的典型例子
# content of test_expectation.py
# coding:utf-8
import pytest
@pytest.mark.parametrize("test_input,expected",
[ ("3+5", 8),
("2+4", 6),
("6 * 9", 42),
])
def test_eval(test_input, expected):
assert eval(test_input) == expected
if __name__ == "__main__":
pytest.main(["-s", "test_canshu1.py"])
2.若要获得多个参数化参数的所有组合，可以堆叠参数化装饰器
import pytest
@pytest.mark.parametrize("x", [0, 1])
@pytest.mark.parametrize("y", [2, 3])
def test_foo(x, y):
print("测试数据组合：x->%s, y->%s" % (x, y))
if __name__ == "__main__":
pytest.main(["-s", "test_canshu1.py"])
