（四）Java版接口自动化-生成优美的测试报告Extentsreport

1、首先在pom.xml文件中添加需要引入的ExtentReport测试报告相关的包。xml代码如下

        
        <dependency>
            <groupId>com.relevantcodesgroupId>
            <artifactId>extentreportsartifactId>
            <version>2.41.1version>
        dependency>
        <dependency>
            <groupId>com.vimalselvamgroupId>
            <artifactId>testng-extentsreportartifactId>
            <version>1.3.1version>
        dependency>
        <dependency>
            <groupId>com.aventstackgroupId>
            <artifactId>extentreportsartifactId>
            <version>3.0.6version>
        dependency>

2、再在testng.xml 文件里配置监听器 ，监听器的xml代码如下

    <listeners>
        <listener class-name="com.automation.interfacetest.extend.ExtentTestNGIReporterListener"/>
    listeners>

完整的testng.xml文件代码如下：

<?xml version="1.0" encoding="UTF-8"?>DOCTYPE suite SYSTEM "http://testng.org/testng-1.0.dtd" >
<suite name="MySute">
    <test name="TestCaseClass">
        <classes>
           <class name="com.automation.interfacetest.TestCase">
           class>
        classes>
    test>
    <listeners>
        <listener class-name="com.automation.interfacetest.extend.ExtentTestNGIReporterListener"/>
    listeners>
suite>

3、新增一个类ExtentTestNGIReporterListener 去实现IReporter

package com.automation.interfacetest.extend;

        if (suites.size() > 1) {
            createSuiteNode = true;
        }
        for (ISuite suite : suites) {
            Map result = suite.getResults();
            //如果suite里面没有任何用例，直接跳过，不在报告里生成
            if (result.size() == 0) {
                continue;
            }

            //存在多个suite的情况下，在报告中将同一个一个suite的测试结果归为一类，创建一级节点。
            if (createSuiteNode) {
                suiteTest = extent.createTest(suite.getName()).assignCategory(suite.getName());
            }
            boolean createSuiteResultNode = false;
            if (result.size() > 1) {
                createSuiteResultNode = true;
            }
            for (ISuiteResult r : result.values()) {

                ITestContext context = r.getTestContext();
                if (createSuiteResultNode) {
                    //没有创建suite的情况下，将在SuiteResult的创建为一级节点，否则创建为suite的一个子节点。
                    if (null == suiteTest) {
                        resultNode = extent.createTest(r.getTestContext().getName());
