2.pytest实现ddt

Pytest实现数据驱动

@pytest.mark.parametrize(“入参名，入参名，...”【可以解包迭代对象】，迭代对象)

unittest实现数据驱动

1. 下载ddt模块pip install ddt

2. from ddt import ddt, data
   
   cases = [
       {"title": "正数", "data": 1, "expect_data": -1},
       {"title": "零", "data": 0, "expect_data": 0},
       {"title": "负数", "data": -1, "expect_data": 1}
   ]
   
   @ddt
   class TestAbs():
   
        @data(*cases)
       def test_abs(self, case):
           '''
           :return:
           '''
           pass
