单元测试记录

                      使用pytest进行单元测试

1.安装测试环境

1.1：安装pytest

pip install pytest

1.2：安装pytest-html

pip install pytest-html

1.3：安装allure-pytest

pip install allure-pytest

2.创建开发文件包

2.1：添加开发文档

class Kaifa():
    def add(self,a,b):
        return a+b
    def reduct(self,a,b):
        return a-b

3.创建测试文档包

3.1：添加文件（csv，xml）（在这里用xml文档）

<jack>
    <aa>
        <a>1</a>
        <a1>2</a1>
        <a2>3</a2>
    </aa>
    <bb>
        <b>5</b>
        <b1>3</b1>
        <b2>2</b2>
    </bb>
</jack>

4.创建读取测试文件包

4.1：添加读取文件（xml）

from xml.dom import minidom
class Testclass():
    def tesst(self,a,b,c):
        jack = minidom.parse(a)
        jack2 = jack.getElementsByTagName(b)[0]
        jack1 = jack2.getElementsByTagName(c)[0].firstChild.data
        return jack1
if __name__ == '__main__':   #这个是在内部运行的功能，在外引用不会读取这个
    t = Testclass()  #验证代码块是否有问题
    print(t.tesst("../cswendang/test.xml","aa","a"))

5.创建单元测试包

5.1添加单元测试

import pytest,allure,os   #导入pytest，allure，os
from duqucswendang.duqutest import Testclass  #导入读取文件代码
from rd.kaifa import Kaifa  #导入开发代码
a = Testclass()
aa = int(a.tesst("../cswendang/test.xml","aa","a"))
aa1 = int(a.tesst("../cswendang/test.xml","aa","a1"))
aa2 = int(a.tesst("../cswendang/test.xml","aa","a2"))
bb = int(a.tesst("../cswendang/test.xml","bb","b"))
bb1 = int(a.tesst("../cswendang/test.xml","bb","b1"))
bb2 = int(a.tesst("../cswendang/test.xml","bb","b2"))
k = Kaifa()
class Testclass():
    @allure.feature("加法")
    @allure.story("成功")
    def test001(self):
        bb = k.add(aa,aa1)
        assert bb == aa2
    @allure.feature("加法")
    @allure.story("这个减法错了")
    def test002(self):
        bb = k.add(aa,aa1)
        assert bb != aa2
    @allure.feature("加法")
    @allure.story("成功")
    def test003(self):
        aa = k.reduct(bb,bb1)
        assert aa == bb2
    @allure.feature("加法")
    @allure.story("这个加法错了")
    def test004(self):
        aa = k.reduct(bb,bb1)
        assert aa != bb2
    def test005(self):
        with allure.step("查看哈吉利系列车信息"):
            allure.attach("博越", "吉利")
        with allure.step("查看哈弗系列车信息"):
            allure.attach("H7", "哈弗")
if __name__ == '__main__':   #这个下面就是allue生成测试报告html类型
    pytest.main(['--alluredir', 'report/result', 'cs_test.py'])  # 生成json类型的测试报告
    split = 'allure ' + 'generate ' + './report/result ' + '-o ' + './report/html ' + '--clean'  # 将测试报告转为html格式
    os.system(split)  # system函数可以将字符串转化成命令在服务器上运行
