步骤 1.添加 Extentreport 依赖 2.新建一个 ExtentTestNGIReporterListener.java3.执行 testNG suite 里添加刚刚自定义监听器

pom.xml 添加 Extentreport 依赖

<dependency>
      <groupId>com.relevantcodes</groupId>
      <artifactId>extentreports</artifactId>
      <version>2.41.1</version>
</dependency>
    <dependency>
    <groupId>com.vimalselvam</groupId>
    <artifactId>testng-extentsreport</artifactId>
    <version>1.3.1</version>
</dependency>
<dependency>
    <groupId>com.aventstack</groupId>
    <artifactId>extentreports</artifactId>
    <version>3.0.6</version>
</dependency>

创建添加一个自定义的 ExtentTestNGIReporterListener 监听器 这个是直接在网上找的

比如输出路径，文件名，报告名...可以自定义修改

testng.xml 执行套件，以下执行了两个测试用例 login_test 和 TestClass

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd">
<suite name="suite" parallel="false" preserve-order="true">
 <test name="webUI auto testing">
    <classes>
        <class name="com.domoyun.login_test"/>
    </classes>
</test> 

    <test name="TestClass"> 
            <classes>
                <class name="com.domoyun.TestClass"/>

            </classes>
        </test>  
    <parameter name="browsetype" value="chrome"></parameter>
    <parameter name="seleniumVersion" value="3.x"></parameter>
    <parameter name="driverPath" value="src/main/resources/driver/ChromeDriver 2.45.exe"></parameter>

   <listeners>
        <listener class-name="com.domoyun.ExtentTestNGIReporterListener"/>
    </listeners>
</suite>

<listeners>
      <listener class-name="com.domoyun.ExtentTestNGIReporterListener"/>
  </listeners>

执行套件里监听器不可少
