【pytest-15】用例a失败，其他关联用例标记为失败xfail

前言

在实际工作场景中，恐怕只有这种登录用例a失败，关联的下个用例b，c也会失败；如果a失败，直接将b，c用例标记为失败

如果登录a都失败，显然b，c都执行不了，这种直接标记为失败，就不用测试了，直接跳过。

用例设计

• pytest里面用xfail标记为失败的用例，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data=[{"user":"admin","pwd":"admin"}]表示

示例：这里以登录，搜索，增加用例为例子

import pytest
data=[{"user":"admin","pwd":"admin"}]

@pytest.fixture(scope="module")
def login(request):
    user=request.param['user']
    pwd=request.param['pwd']
    print("登录用户名：%s" % user)
    print("登录密码:%s" % pwd)
    if pwd:
        return True
    else:
        return False

@pytest.mark.parametrize("login",data,indirect=True)
class TestCalss:
    def test_login(self,login):
        '''登录'''
        result=login
        print("登录用例的结果：%s"%result)
        assert result==True

    def test_search(self,login):
        '''搜索'''
        result=login
        print("搜索用例的结果：%s" % result)
        assert result == True
       def test_add(self,login):
        '''增加'''
        result=login
        print("增加用例的结果：%s" % result)
        assert result == True
        if __name__ == '__main__':
    pytest.main(["-s","test_login.py"])

运行结果：

Testing started at 14:13 ...============================= test session starts =============================collected 3 items

test_login.py 登录用户名：admin

通过看运行结果，是成功运行的

标记为xfail

在看看登录失败情况的用例，修改登录的参数

import pytest
data=[{"user":"admin","pwd":""}]

@pytest.fixture(scope="module")
def login(request):
    user=request.param['user']
    pwd=request.param['pwd']
    print("登录用户名：%s" % user)
    print("登录密码:%s" % pwd)
    if pwd:
        return True
    else:
        return False

@pytest.mark.parametrize("login",data,indirect=True)
class TestCalss:
    def test_login(self,login):
        '''登录'''

        assert result==True

    def test_search(self,login):
        '''搜索'''
        result=login
        print("搜索用例的结果：%s" % result)
        # assert result == True
        if not result:
            pytest.xfail("登录不成功，标记为xfail")

    def test_add(self,login):
        '''增加'''
        result=login
        print("增加用例的结果：%s" % result)
        # assert result == True
        if not result:
            pytest.xfail("登录不成功，标记为xfail")


if __name__ == '__main__':
    pytest.main(["-s","test_login.py"])

从运行结果可以看出，登录用例失败了，搜索用例和增加用例没执行，直接标记为xfail了。
