一、前言

上篇文章有提及pytest.mark.parametrize的使用，这次在此基础上结合fixture和request再做个延伸。

二、传单个参数

即一个参数一个值，示例代码如下：

# 传单个参数
@pytest.fixture()
def getuser(request):
    user = request.param
    print(f" 获取用户: {user}")
    return user


data = ["lilei","jojo","hanmeimei"]
# 用英文哈,中文会被加密
ids = [f" mark input ：{user} " for user in data]


@pytest.mark.parametrize("getuser",data,ids=ids,indirect=True)
class TestClass(object):
    def test_getuser(self,getuser):
        print(f"输出用户信息：{getuser}")

运行结果如下：

三、传多个参数

即结合字典的使用，示例代码如下：

# 传多个参数
@pytest.fixture()
def getlogins(request):
    param = request.param
    print(f" 获取用户名: {param['username']} 获取密码：{param['password']}")
    return param


data = [{"username": "jojo","password": "123456"},{"username": "hanmeimei",{"username": "lilei","password": "123456"}]


@pytest.mark.parametrize("getlogins",indirect=True)
def test_getlogin(getlogins):
    print(f"用户名：{getlogins['username']} 密码：{getlogins['password']}")

运行结果如下：

四、一个装饰器加多个fixture

一个装饰器的意思就是，数据源是一个，这次我们用元祖来做数据源，示例代码如下：

# 一个装饰器+多个fixture
@pytest.fixture(scope="module")
def getusername(request):
    username = request.param
    print(f" username is {username}")
    return username


@pytest.fixture(scope="module")
def getpassword(request):
    password = request.param
    print(f" password is {password}")
    return password


data = [("jojo","1"),("lilei","123654")]


@pytest.mark.parametrize("getusername,getpassword",indirect=True)
def test_getUserinfo(getusername,getpassword):
    print(f"用户名：{getusername} 密码：{getpassword}")

运行结果如下：

五、多个装饰器+多个fixture

就是多个数据源，这次用list来做演示，示例代码如下：

# 多个装饰器+多个fixture
@pytest.fixture()
def users(request):
    user = request.param
    print(f" 用户名：{user}")
    return user


@pytest.fixture()
def pwds(request):
    pwd = request.param
    print(f" 密码：{pwd}")
    return pwd


data1 = ["lilei","hameimei","jojo"]
data2 = ["1","2","3"]


@pytest.mark.parametrize("users",data1,indirect=True)
@pytest.mark.parametrize("pwds",data2,indirect=True)
def test_getuserinfo(users,pwds):
    print(f"用户名为：{users} 密码为：{pwds}")

运行结果如下：
