测试报告ExtentReport改进

具体步骤
Step-1：在pom.xml文件中添加 Maven 依赖包

</project>

Step-2：重写 ExtentTestNgFormatter 类
主要基于以下两项原因：

1.支持报告中展示更多状态类型的测试结果，例如：成功、失败、警告、跳过等。
2.因为不支持cdn.rawgit.com访问，故替css访问方式。
创建 MyExtentTestNgFormatter 类
下载 ExtentReportes 源码，找到 ExtentTestNgFormatter 类，Listener 目录下创建 MyExtentTestNgFormatter.java 类直接继承 ExtentTestNgFormatter 类。

页面乱或者乱码，解决CDN无法访问
构造方法加入

htmlReporter.config().setResourceCDN(ResourceCDN.EXTENTREPORTS);
具体代码如下：

package com.extentreport.listener;

import com.aventstack.extentreports.ExtentReports;
import com.aventstack.extentreports.ExtentTest;

重写 onstart 方法
重写onstart 方法功能。新建一个类名为MyReporter，一个静态ExtentTest的引用。

package com.extentreport.listener;

import com.aventstack.extentreports.ExtentTest;

/**
 * @Auther: ***
 * @Date: 2019/3/1
 * @Description:
 */
public class MyReporter {
    public static ExtentTest report;
    private static String testName;

    public static String getTestName() {
        return testName;
    }

    public static void setTestName(String testName) {
        MyReporter.testName = testName;
    }
}

　　

自定义配置
测试报告默认是在工程根目录下创建 test-output/ 文件夹下，名为report.html、emailable-report.html。可根据各自需求在构造方法中修改。

report.log
report.log 支持多种玩法

// 根据状态不同添加报告。型如警告
MyReporter.report.log(Status.WARNING, "接口耗时(ms)：" + String.valueOf(time));

直接从TestClass 中运行时会报 MyReporter.report 的空指针错误，需做判空处理。

Step-3：配置监听
在测试集合 testng.xml 文件中导入 Listener 监听类。

 <listeners>
        <!--测试报告监听器：修改自己的包名地址-->
         <listener class-name="com.extentreport.listener.MyExtentTestNgFormatter"/>

     </listeners>

Step-4：配置报告
extent reporters支持报告的配置。目前支持的配置内容有title、主题等。
先在src/resources/目录下添加 config/report/extent-config.xml。

<?xml version="1.0" encoding="UTF-8"?>
<extentreports>
    <configuration>
        <timeStampFormat>yyyy-MM-dd HH:mm:ss</timeStampFormat>
        <!-- report theme -->
        <!-- standard, dark -->
        <theme>dark</theme>

        <!-- document encoding -->
        <!-- defaults to UTF-8 -->
        <encoding>UTF-8</encoding>

        <!-- protocol for script and stylesheets -->
        <!-- defaults to https -->
        <protocol>https</protocol>

        <!-- title of the document -->
        <documentTitle>UI自动化测试报告</documentTitle>

        <!-- report name - displayed at top-nav -->
        <reportName>UI自动化测试报告</reportName>

        <!-- report headline - displayed at top-nav, after reportHeadline -->
        <reportHeadline>UI自动化测试报告</reportHeadline>

        <!-- global date format override -->
        <!-- defaults to yyyy-MM-dd -->
        <dateFormat>yyyy-MM-dd</dateFormat>

        <!-- global time format override -->
        <!-- defaults to HH:mm:ss -->
        <timeFormat>HH:mm:ss</timeFormat>

        <!-- custom javascript -->
        <scripts>
            <![CDATA[
        $(document).ready(function() {

        });
      ]]>
        </scripts>

        <!-- custom styles -->
        <styles>
            <![CDATA[

      ]]>
        </styles>
    </configuration>
</extentreports>　　

Step-5：配置系统系统
config下新建 MySystemInfo类继承 SystemInfo 接口

package com.extentreport.config;
import com.vimalselvam.testng.SystemInfo;

import java.io.IOException;
import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;
import java.util.Properties;

/**
 * @Auther: ***
 * @Date:2019/3/1
 * @Description:
 */
public class MySystemInfo implements SystemInfo {

    @Override
    public Map<String, String> getSystemInfo() {

        Map<String, String> systemInfo = new HashMap<>();
        systemInfo.put("测试人员", "author");

        return systemInfo;
    }
}

　　

可用于添加系统信息，例如：db的配置信息，人员信息，环境信息等。根据项目实际情况添加。
至此，extentreports 美化报告完成。

Step-6：添加测试用例

public class TestMethodsDemo {

    @Test
    public void test1(){
        Assert.assertEquals(1,2);
    }

    @Test
    public void test2(){
        Assert.assertEquals(1,1);
    }


    @Test
    public void test3(){
        Assert.assertEquals("aaa","aaa");
    }


    @Test
    public void logDemo(){
        Reporter.log("这是故意写入的日志");
        throw new RuntimeException("故意运行时异常");
    }
}

　　

Step-7：测试用例suite

<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >

<suite name="测试demo" verbose="1" preserve-order="true">
    <parameter name="report.config" value="src/main/resources/report/extent-config.xml"/>
    <parameter name="system.info" value="com.zuozewei.extentreportdemo.config.MySystemInfo"/>

    <test name="测试demo" preserve-order="true">
        <classes>
            <class name="com.zuozewei.extentreportdemo.testCase.TestMethodsDemo"/>
        </classes>
    </test>

    <listeners>
        <listener class-name="com.zuozewei.extentreportdemo.listener.MyExtentTestNgFormatter"/>
    </listeners>
