pytest数据驱动pytest.mark.parametrize

parametrize 

支持元组，列表

支持列表嵌套列表，列表嵌套元组，列表嵌套字典

支持类和函数的参数化

1、单个变量

    @pytest.mark.parametrize('user', ("zhangsan", "lisi"))
    def test_01(self,user):
        print(user)

2、单个变量参数为 列表

    datatest04=['zhangsan','lisi']
    @pytest.mark.parametrize('user', datatest04)
    def test_04(self,user):
        print(user)

　

3、单个变量参数为 元组

    datatest08=("zhangsan","lisi")
    @pytest.mark.parametrize("data", datatest08)
    def test_08(self,data):
        print(data)

　　

4、多个变量

    @pytest.mark.parametrize('user,password',[("zhangsan","111111"),("lisi","222222")])
    def test_02(self,user,password):
        print(user,password)

5、多个变量组成列表嵌套元组

    data =[("zhangsan","111111111"),("lisi","2222222")]
    @pytest.mark.parametrize('user,password',data)
    def test_03(self,user,password):
        print(user,password)

　

6、多个变量组成列表嵌套列表

    data =[["zhangsan","111111111"],["lisi","2222222"]]
    @pytest.mark.parametrize('user,password',data)
    def test_05(self,user,password):
        print(user,password)

7、针对类参数化--不知道应用场景

@pytest.mark.parametrize('user,password',[("zhangsan","111111"),("lisi","222222")])
class Testdemo1(object):
    def test_01(self,user,password):
        print(user,password)

    def test_02(self,user,password):
        print(user,password)

　　

8、组合函数-笛卡尔集

    data1 =["zhangsan","lisi"]
    data2 = ["1111111", "2222222"]
    @ pytest.mark.parametrize('user', data1)
    @pytest.mark.parametrize('password',data2)
    def test_06(self,user,password):
        print(user,password)

　　

错误写法

    data1 =["zhangsan","111111111"]
    data2 = ["lisi", "2222222"]
    @ pytest.mark.parametrize('user,password', data1)
    @pytest.mark.parametrize('user,password',data2)
    def test_06(self,user,password):
        print(user,password)

　9、列表嵌套字典

    datatest07 = [{"user":"zhangsan", "password":"111111111"},{"user":"lisi","password":"222222"}]
    @pytest.mark.parametrize("data", datatest07)
    def test_07(self,data):
        print(data)
        print(data["user"],data["password"])

　

 错误写法

    datatest07 = [{"user":"zhangsan", "password":"111111111"},{"user":"lisi","password":"222222"}]
    @pytest.mark.parametrize("user,password", datatest07)
    def test_07(self,data):
        print(data)
        print(data["user"],data["password"])
