pytest文档23-使用多个fixture和fixture直接互相调用

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。

# test_fixture4.py

import pytest

@pytest.fixture()

def user():

    print("获取用户名")

    a = "yoyo"

    b = "123456"

    return (a, b)

def test_1(user):

    u = user[0]

    p = user[1]

    print("测试账号：%s, 密码：%s" % (u, p))

    assert u == "yoyo"

if __name__ == "__main__":

    pytest.main(["-s", "test_fixture4.py"])

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

# test_fixture5.py

import pytest

@pytest.fixture()

def user():

    print("获取用户名")

    a = "yoyo"

    return a

@pytest.fixture()

def psw():

    print("获取密码")

    b = "123456"

    return b

def test_1(user, psw):

    '''传多个fixture'''

    print("测试账号：%s, 密码：%s" % (user, psw))

    assert user == "yoyo"

if __name__ == "__main__":

    pytest.main(["-s", "test_fixture5.py"])

fixture与fixture互相调用

fixture与fixture直接也能互相调用的

import pytest

@pytest.fixture()

def first():

    print("获取用户名")

    a = "yoyo"

    return a

@pytest.fixture()

def sencond(first):

    '''psw调用user fixture'''

    a = first

    b = "123456"

    return (a, b)

def test_1(sencond):

    '''用例传fixture'''

    print("测试账号：%s, 密码：%s" % (sencond[0], sencond[1]))

    assert sencond[0] == "yoyo"

if __name__ == "__main__":

    pytest.main(["-s", "test_fixture6.py"])
