项目简介

测试地址

https://mail.126.com

测试范围

1.126电子邮箱登录功能测试-验证正确帐号密码登录成功-验证错误用户名密码登录失败（有很多情况，用例里面做了充分的校验）

2.126电子邮箱添加联系人功能测试-验证正确填写必填项数据添加联系人成功-验证缺省必填项数据添加联系人失败-验证必填项字段数据格式错误添加联系人失败

3.126电子邮箱发送邮件功能测试-验证普通邮件发送成功-验证带附件邮件发送成功

项目设计

1.python编程语言设计测试脚本

2.webdriver驱动浏览器并操作页面元素

3.二次封装webdriver Api 操作方法

4.采用PageObject设计模式，设计测试业务流程

5.通过UI对象库存储页面操作元素

6.通过数据文件存储数据，读取数据，参数化测试用例并驱动测试执行

7.通过第三方插件pytest-html生成测试报告

8.通过yagmail第三方库，编写发送报告接口，测试工作完成后自动发送测试报告

代码实现

通过126邮箱测试范围分析，我们需要通过设计剪切板，模拟键盘完成附件上传操作，因此我们首先来编写这两个方法

login

contact

mail

数据，UI对象库，解析方法都已经有了，接下来通过PageObject模式设计编写每个页面的操作及封装126邮箱的功能，以便后续设计用例调用

问题

用例已经写完了，有两个问题

1.有没有发现我们的报告怎么生成的？也没有失败用例截图？

2.我们貌似并没有编写驱动浏览器的代码？

现在我们来解决这个两个问题根据pytest的conftest.py文件的原理，我们可以把驱动浏览器的代码写在一个全局的conftest.py文件里面。报告生成其实是通过命令 pytest --html=‘report.html’ --self-contained-html生成的，但是这样的报告对用例的描述不是很清晰，且没有对失败用例截图，也不方便我们分析项目的缺陷，我们也可以填写代码放到这个文件里面

运行项目

通过命令运行

1.cmd切换到项目的根目录，执行pytest --html=‘report.html’ --self-contained-html命令（此运行方式，无法发送测试报告邮件）这种方式感觉有点low，我们换另外一种方式，可以通过os模块自动执行相关命令，编写运行用例代码

我们可以直接执行这个文件执行所用的测试用例了！

其实我们运行用例往往不只是 使用pytest --html=‘report.html’ --self-contained-html 这样一个简单的命令运行，通常会添加很多的命令选项，比如-v,-q,-s等等，那么怎么办呢？这时候就用到了pytest.ini配置文件了

只添加了几个简单的命令选项

1 [pytest]
2 addopts=-vqs
3 testpaths=./TestCases
4 markers=
5     loginTest: Run login test cases
6     contactTest: Run add contact test cases
7     sendMailTest: Run send mail test cases

测试输出

1.自动生成html格式报告，其中报告里面附带用例执行日志明细，及用例失败自动截图(部分报告展示)

2.自动发送测试邮件给指定用户
