unittest+数据读取

测试数据分离

unittest+文件存放测试数据

 数据驱动装饰圈 ddt.ddt  ddt.data()  unpack   ddt.file_data()
 文件读取 txt  readlines  strip  split
        json  json.load
        excel  xlrd.open_workbook  book.sheet_by_name  sheet.nrows sheet.row_values
        yaml 不用写读取方法 ddt.file_data()可自动解包  yaml中用列表套字典方式传递
文件类容解析为  [{"user": "admin","pwd": 123},{"user": "wang","pwd": 234}]

unitest框架基础

执行流程

setUpClass->setUp--用例--tearDown-->tearDownClass

class MyTestCase(unittest.TestCase):
    @classmethod
    def setUpClass(cls) -> None:
        print("测试结束")

    @classmethod
    def tearDownClass(cls) -> None:
        print("测试开始")

    def setUp(self) -> None:
        print("用例执行前")

    def tearDown(self) -> None:
        print("用例执行后")

变量传递

用类变量中list或dict可以传递参数

class MyTestCase(unittest.TestCase):
    dic = {}

    def test_case1(self):
        self.dic["session"] = "ABCD"

    def test_case2(self):
        print(self.dic)
