使用多个fixture

如果用例需要用到多个fixture的返回数据，fixture也可以return一个元组、list或字典，然后从里面取出对应数据。

# -*- coding=utf-8 -*-

import pytest
@pytest.fixture()
def user():
    a="admin"
    b="123456"
    return (a,b)
def test_t1(user):
    u=user[0]
    p=user[1]
    print("user类型{}".format(type(user))) #查看返回类型
    print("用户名:{},密码：{}".format(u,p))
    assert u=="admin"
if __name__ == "__main__":
    pytest.main(["-s", " test_001.py"])

运行结果：

                                                            [100%]

当然也可以分开定义成多个fixture,然后test_用例传多个fixture参数

# -*- coding=utf-8 -*-

import pytest
@pytest.fixture()
def user():
    a = "admin"
    return a
@pytest.fixture()
def pwd():
    p = "888888"
    return p
def test_t1(user, pwd):
    u = user
    p = pwd
    print("user类型{}".format(type(user)))  # 查看返回类型
    print("用户名:{},密码：{}".format(u, p))
    assert p == '888888'
if __name__ == "__main__":
    pytest.main(["-s", " test_001.py"])

运行结果

fixture与fixture互相调用

import pytest
@pytest.fixture()
def user():
    a = "admin"
    return a
@pytest.fixture()
def pwd(user):
    p = "888888"
    return user, p
def test_t1(user, pwd):
    u = user
    p = pwd[1]
    print("pwd类型{}".format(type(pwd)))  # 查看返回类型
    print(f"pwd类型{pwd}") 
    print("用户名:{},密码：{}".format(u, p))
    assert p != None
if __name__ == "__main__":
    pytest.main(["-s", " test_001.py"])
