pytest 14 使用自定义标记mark

标记失败用到的情况是，本身就知道这是失败的例子，所以，不用让他运行，直接跳过。或者是依赖于某个方法，某个方式失败的话，用例直接标记成失败。

标记失败有两种方法，一种是方法内部，一种是方法外部。内部用pytest.xfail(""),外部用装饰@pytest.mark.xfail(condition=None, *, reason=None, raises=None, run=True, strict=False)

具体看以下的两个例子：

#!/usr/bin/env/python
# -*-coding:utf-8-*-
import pytest

parameter = [{"user":"admin","password":""}]

@pytest.mark.xfail(reason="no run")
def test_mark():
    pass

@pytest.fixture(scope="module")
def login(request):
    user = request.param["user"]
    password = request.param["password"]
    print("正在操作登录，账号：%s, 密码：%s" % (user, password))
    if password:
        return True
    else:
        return False

@pytest.mark.parametrize("login",parameter,indirect=True)
class Test_xfail():

    def test_01(self,login):
        """用例1登录"""
        result = login
        print("用例1：%s" % result)
        assert result == True

    def test_02(self, login):
        result = login
        print("用例2,登录结果：%s" % result)
        if not result:
            pytest.xfail("登录不成功, 标记为xfail")

        assert 1 == 1

    def test_03(self, login):
        result = login
        print("用例3,登录结果：%s" % result)
        if not result:
            pytest.xfail("登录不成功, 标记为xfail")

        assert 1 == 1

运行结果：显示一个跳过，3个通过

下面的一个，让密码为空

#!/usr/bin/env/python
# -*-coding:utf-8-*-
import pytest

parameter = [{"user":"admin","password":""}]

@pytest.mark.xfail(reason="no run")
def test_mark():
    pass

@pytest.fixture(scope="module")
def login(request):
    user = request.param["user"]
    password = request.param["password"]
    print("正在操作登录，账号：%s, 密码：%s" % (user, password))
    if password:
        return True
    else:
        return False

@pytest.mark.parametrize("login",parameter,indirect=True)
class Test_xfail():

    def test_01(self,login):
        """用例1登录"""
        result = login
        print("用例1：%s" % result)
        assert result == True

    def test_02(self, login):
        result = login
        print("用例2,登录结果：%s" % result)
        if not result:
            pytest.xfail("登录不成功, 标记为xfail")

        assert 1 == 1

    def test_03(self, login):
        result = login
        print("用例3,登录结果：%s" % result)
        if not result:
            pytest.xfail("登录不成功, 标记为xfail")

        assert 1 == 1

运行结果：显示一个失败，一个跳过（xpass），用例2和3没执行，直接标记为xfail了
