单元测试:pytest

命名规则

前提条件：需要下载pytest-html模块(python自带的生成测试报告模块)

pip install pytest-html

Pytest调用语句

Pytest的运行方式

拿取数据 

1.  
   from xml.dom import minidom
2.  
   class ReadXml():
3.  
   # def readxml(self):
4.  
   # # parse解析哪个xml文件
5.  
   # #../返回上一级 解析test01.xml
6.  
   # #root随意起名
7.  
   # root = minidom.parse("../data/test01.xml")
8.  
   # #add对应的标签
9.  
   # firstnode=root.getElementsByTagName("add")[0]
10.  
    # #拿到add里面的数据 firstChild.data获取第一个
11.  
    # secondnode=firstnode.getElementsByTagName("exepiton")[0].firstChild.data
12.  
    # return secondnode
13.  
    # # #打印
14.  
    # # print(root)
15.  
     
16.  
    # parse解析哪个xml文件
17.  
    # ../返回上一级 解析test01.xml
18.  
    # root随意起名
19.  
    def readxml(self,path,firstname,secondname):
20.  
    #传进文件路径
21.  
    root = minidom.parse(path)
22.  
    firstnode = root.getElementsByTagName(firstname)[0]
23.  
    secondnode = firstnode.getElementsByTagName(secondname)[0].firstChild.data
24.  
    return secondnode
25.  
    # #打印
26.  
    # print(root)
27.  
    #调用实例化对象 print输出
28.  
    print(ReadXml().readxml("../data/test01.xml","add","exepiton"))

导入pytest验证是否通过

1.  
   #导入
2.  
   import pytest
3.  
   class TestClass():
4.  
   # def setup(self):
5.  
   # print("setup")
6.  
   # @classmethod
7.  
   # def setup_class(cls):
8.  
   # print("setup_class")
9.  
   # def test001(self):
10.  
    # print("我是test001")
11.  
    # def test002(self):
12.  
    # print("我是test002")
13.  
    # def teardown(self):
14.  
    # print("teardown")
15.  
    # @classmethod
16.  
    # def teardown_class(cls):
17.  
    # print("teardown_class")
18.  
    def test001(self):
19.  
    assert 3==4
20.  
    def test002(self):
21.  
    assert 2==2
22.  
    #跳过语句
23.  
    @pytest.mark.skip
24.  
    def test003(self):
25.  
    assert 1==1
26.  
    if __name__ == '__main__':
27.  
    #加入参数只执行一个 放入路径
28.  
    # pytest.main(["-s","test_001.py"])
29.  
    #生成测试报告
30.  
    pytest.main(["-s","test_001.py","--html=./report.html"])

 类名规则报错

 加入参数 -s才能出运行结果

报错为 没有权限

 解决方法 加入下载pytest

 然后生成测试报告

跳过语句的演示 

 测试报告显示出

 f报错 .为通过  s为跳过

 参数必须加入命名才能运行出来

 testxml代码

1.  
   from calcdemo.calc import Calc
2.  
   from readdata.readxml import ReadXml
3.  
   import pytest
4.  
   #实例化
5.  
   c = Calc()
6.  
   r = ReadXml()
7.  
   qq=int(r.readxml("../data/test1.xml","cheng","cheng1"))
8.  
   ww=int(r.readxml("../data/test1.xml","cheng","cheng2"))
9.  
   ee=int(r.readxml("../data/test1.xml","cheng","execption"))
10.  
    rr=int(r.readxml("../data/test1.xml","chu","chu1"))
11.  
    tt=int(r.readxml("../data/test1.xml","chu","chu2"))
12.  
    yy=int(r.readxml("../data/test1.xml","chu","execption"))
13.  
    class TestXml():
14.  
    def test001(self):
15.  
    #拿到实际结果
16.  
    result = c.cheng(qq,ww)
17.  
    assert result ==ee
18.  
    def test002(self):
19.  
    result = c.chu(rr,tt)
20.  
    assert result == yy
21.  
    if __name__ == '__main__':
22.  
    pytest.main(["--html=./report.html","testxml.py"])

readxml代码块

1.  
   from xml.dom import minidom
2.  
   class ReadXml():
3.  
   def readxml(self,past,firstname,secondname):
4.  
   #拿到根数据
5.  
   root = minidom.parse(past)
6.  
   firstname = root.getElementsByTagName(firstname)[0]
7.  
   secondname = firstname.getElementsByTagName(secondname)[0].firstChild.data
8.  
   return secondname
9.  
   #验证
10.  
    if __name__ == '__main__':
11.  
    r = ReadXml()
12.  
    #打印数据
13.  
    print(r.readxml())
