pytest_用例a失败，跳过测试用例b和c并标记失败xfail

前言

当用例a失败的时候，如果用例b和用例c都是依赖于第一个用例的结果，那可以直接跳过用例b和c的测试，直接给他标记失败xfail
用到的场景，登录是第一个用例，登录之后的操作b是第二个用例，登录之后操作c是第三个用例，很明显三个用例都会走到登录。
如果登录都失败了，那后面2个用例就没测试必要了，直接跳过，并且标记为失败用例，这样可以节省用例时间。

用例设计

1.pytest里面用xfail标记用例为失败的用例，可以直接跳过。实现基本思路

• 把登录写为前置操作
• 对登录的账户和密码参数化，参数用canshu = [{"user":"amdin", "psw":"111"}]表示
• 多个用例放到一个Test_xx的class里
• test_01，test_02， test_03全部调用fixture里面的login功能
• test_01测试登录用例
• test_02和test_03执行前用if判断登录的结果，登录失败就执行，pytest.xfail("登录不成功, 标记为xfail"

test_login.py

import pytest
import requests
 
s = requests.session()
canshu = [{'user':'xxxx',
           'paw':111111,
           'uri':'xxxxxxxxxx'}]
 
@pytest.fixture(scope='module')
 
def login(request):
    user = request.param['user']
    paw = request.param['paw']
    uri = request.param['uri']
 
    url = uri + "/global/do-login.action"
    body = {
        "loginName": "%s" % user,
        "password": "%s" % paw,
        "pcCodeForFocusMedia": 0
    }
    a = s.post(url, data=body, verify=False)
    data = a.json()
    print(data['status'])
    if data['status'] == 202:
        return True
    else:
        return False

test_parametrize.py

import pytest, requests, urllib3
from s14.pytest_learn import test_login
urllib3.disable_warnings()
 
canshu = test_login.canshu
login = test_login.login
 
tenantId = xxx # 租户ID
encryptionKey = "xxxxxxxxx"  # 保持登陆的key
passport_id = xxxxx # 跟据账号进行填写，同一个账户下的多个租户，passport.id不用更改
uri = 'xxxx'
user = 'xxxx'
 
@pytest.mark.parametrize('login', canshu, indirect=True)
class Test_xxxx():
 
    s = requests.session()
    def test_01(self, login):
        '''登陆'''
        result = login
        print("用例1: %s" % result)
        assert result == True
 
    def test_02(self, login):
        result = login
        print("用例2: %s" % result)
        url1 = uri + "/global/login-entry.action"
        body1 = {
            "tenantId": "%s" % tenantId,
            "passport.id": passport_id,
            "encryptionKey": "%s" % encryptionKey,
            "loginName": "%s" % user
        }
        b = self.s.post(url1, data=body1, verify=False)
        data = b.json()
        a = data['status']
        if not result:
            pytest.xfail("登陆不成功，标记为xfail")
        else:
            print("用例2运行结果为 ：True , data['status']状态为：%s" % a)
        assert data['status'] == 0
 
if __name__ == '__main__':
    pytest.main(['-s', 'test_parametrize.py'])

上面传的登录参数是登录成功的案例，两个用例全部通过

============================= test session starts =============================

用例2运行结果为 ：True , data['status']状态为：0

标记为xfail

1.再看看登录失败情况的用例,修改登录的参数

import pytest
import requests
 
s = requests.session()
canshu = [{'user':'xxxxx',
           'paw':'',
           'uri':'xxxxxx'}]
 
@pytest.fixture(scope='module')
 
def login(request):
    user = request.param['user']
    paw = request.param['paw']
    uri = request.param['uri']
 
    url = uri + "/global/do-login.action"
    body = {
        "loginName": "%s" % user,
        "password": "%s" % paw,
        "pcCodeForFocusMedia": 0
    }
    a = s.post(url, data=body, verify=False)
    data = a.json()
    print(data['status'])
    if data['status'] == 202:
        return True
    else:
        return False

test_parametrize.py

import pytest, requests, urllib3
from s14.pytest_learn import test_login
urllib3.disable_warnings()
 
canshu = test_login.canshu
login = test_login.login
 
tenantId = xxx # 租户ID
encryptionKey = "xxxxxxxxx"  # 保持登陆的key
passport_id = xxxxx # 跟据账号进行填写，同一个账户下的多个租户，passport.id不用更改
uri = 'xxxx'
user = 'xxxx'
 
@pytest.mark.parametrize('login', canshu, indirect=True)
class Test_xxxx():
 
    s = requests.session()
    def test_01(self, login):
        '''登陆'''
        result = login
        print("用例1: %s" % result)
        assert result == True
 
    def test_02(self, login):
        result = login
        print("用例2: %s" % result)
        url1 = uri + "/global/login-entry.action"
        body1 = {
            "tenantId": "%s" % tenantId,
            "passport.id": passport_id,
            "encryptionKey": "%s" % encryptionKey,
            "loginName": "%s" % user
        }
        b = self.s.post(url1, data=body1, verify=False)
        data = b.json()
        a = data['status']
        if not result:
            pytest.xfail("登陆不成功，标记为xfail")
        else:
            print("用例2运行结果为 ：True , data['status']状态为：%s" % a)
        assert data['status'] == 0
 
if __name__ == '__main__':
    pytest.main(['-s', 'test_parametrize.py'])

运行结果

============================= test session starts =============================

从结果可以看出用例1失败了，用例2和3没执行，直接标记为xfail了
