文章标签 java selenium 读取接口测试 json python html 文章分类 Java 后端开发

一、摘要

本博文将介绍Python和Selenium做自动化测试的时候，基于unittest框架，借助ddt模块使用json文件作为数据文件作为测试输入，最后生成html测试报告

二、json文件

[
  "北京||北京","上海||上海","广州||广州","深圳||深圳","香港||香港"
]

三、ReportTemplate.py

# encoding = utf-8
"""
__title__ = 'DataDrivenTestByDDT use this template for generating testing report'
__author__ = 'davieyang'
__mtime__ = '2018/4/21'
"""
# encoding = utf-8
def htmlTemplate(trData):
    htmlStr = u'''<!DOCTYPE HTML>
    <html>
    <head>
    <title>单元测试报告</title>
    <style>
    body {
        width:80%;
        margin:40px auto;
        font-weight:bold;
        font-family: 'trebuchet MS', 'Lucida sans', SimSun;
        font-size:18px;
        color: #000;
    }
    table {
        * border-collapse:collapse;
        border-spacing:0;
        width:100%;
    }
    .tableStyle {
        /* border:solid #ggg 1px;*/
        border-style:outset;
        border-width:2px;
        /*border:2px;*/
        border-color:blue;
    }
    .tableStyle tr:hover {
        background: rgb(173.216.230);
    }
    
    .tableStyle td,.tableStyle th{

        border-top:1px solid rgb(146,208,80);
        padding:15px
        text-align:center
    }
    .tableStyle th{
        padding:15px;
        background-color:rgb(146,208,80);
        /*表格标题栏设置渐变颜色*/
        background-image: -webkit -gradient(linear, left top, left bottom, from(#92D050), to(#A2D668))
        /*rgb(146,208,80)*/
    }     
    </style>
    </head>
    <body>
        <center><h1>测试报告</h1></center><br />
        <table class="tableStyle">
            <thead>
            <tr>
            <th>Search Words</th>
            <th>Assert Words</th>
            <th>Start Time</th>
            <th>Waste Time(s)</th>
            <th>Status</th>
            </tr>
            </thead>'''
    endStr = u'''
        </table>
    </body>
    </html>'''
    html = htmlStr + trData + endStr
    print(html)
    with open("D:\\\Programs\\\Python\\\PythonUnittest\\\Reports\\testTemplate.html", "wb") as fp:
        fp.write(html.encode("gbk"))

        # 每一组数据测试结束后，都将其测试结果信息插入表格行的HTML代码中，并将这些行HTML代码拼接到变量trStr变量中，

五、生成日志
