fixture传参的request的使用

• 为了提高复用性，我们在写测试用例的时候，会用到不同的fixture，比如：最常见的登录操作，大部分的用例的前置条件都是登录
• 假设不同的用例想登录不同的测试账号，那么登录fixture就不能把账号写死，需要通过传参的方式来完成登录操作

传入单个参数

import pytest

@pytest.fixture()
def login(request):
    name = request.param
    print(f'账号是{name}')
    return name

data = ["test1","test2"]
ids = [f'login_test_name is {name}' for name in data]

@pytest.mark.parametrize('login',data,ids=ids,indirect=True)
def test_name(login):
    print(f'测试用例的登录账号是{login}')

注：

• 添加 indirect=True 参数是为了把 login 当成一个函数去执行，而不是一个参数，并且将data当做参数传入函数
• def test_name(login) ，这里的login是获取fixture返回的值

传入多个参数

import pytest
@pytest.fixture()
def logins(request):
    param = request.param
    print(f"账号是：{param['username']}，密码是：{param['pwd']}")
    return param

data = [
    {"username": "name1", "pwd": "pwd1"},
    {"username": "name2", "pwd": "pwd2"},
]

@pytest.mark.parametrize("logins", data, indirect=True)
def test_name_pwd(logins):
    print(f"账号是：{logins['username']}，密码是：{logins['pwd']}")

注:

如果需要传多个参数，需要通过字典去传

多个fixture(只加一个装饰器）----常用的

@pytest.fixture(scope='module')
def input_user(request):
    user = request.param
    print(f'账号是{user}')
    return user

@pytest.fixture(scope='module')
def input_pwd(request):
    pwd = request.param
    print(f'密码是{pwd}')
    return pwd

data = [
    ("name1", "pwd1"),
    ("name2", "pwd2")
]

@pytest.mark.parametrize("input_user,input_pwd", data, indirect=True)
def test_case1(input_user,input_pwd):
    print(f'账号是{input_user}，密码是{input_pwd}')

多个fixture(叠加装饰器)

# 多个fixture
@pytest.fixture(scope="function")
def input_user(request):
    user = request.param
    print("登录账户：%s" % user)
    return user


@pytest.fixture(scope="function")
def input_psw(request):
    psw = request.param
    print("登录密码：%s" % psw)
    return psw


name = ["name1", "name2"]
pwd = ["pwd1", "pwd2"]


@pytest.mark.parametrize("input_user", name, indirect=True)
@pytest.mark.parametrize("input_psw", pwd, indirect=True)
def test_more_fixture(input_user, input_psw):
    print("fixture返回的内容:", input_user, input_psw)
