IReporter 的用法，转载（https://www.cnblogs.com/zhangfei/p/4514697.html）

IReporter接口是干嘛的？就是让用户自定义报告的，很多人想要自定义报告，于是乎找各种插件，比如什么testng-xslt啊，reportng啊，各种配置，最后出来的结果，还不能定制化，但为什么不能自已定制一份呢？testng的IReporter接口就接供了这样的功能，我们只需要实现这个接口，并加上监听，就能拿到所有的信息了，你可以把这些信息存数据库，或者自已生成一个html，亦或者写在EXCEL里啊等等，都可以，下面给出IReporter接口的实现方式：

package com.demo;

 

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileWriter;

import java.io.IOException;

import java.text.SimpleDateFormat;

import java.util.ArrayList;

import java.util.Collections;

import java.util.Comparator;

import java.util.List;

import java.util.Map;

import java.util.Set;

 

import org.testng.IReporter;

import org.testng.IResultMap;

import org.testng.ISuite;

import org.testng.ISuiteResult;

import org.testng.ITestContext;

import org.testng.ITestResult;

import org.testng.xml.XmlSuite;

 

public class NewReport implements IReporter{

     

    @Override

    public void generateReport(List<XmlSuite> xmlSuites, List<ISuite> suites, String outputDirectory) {

        List<ITestResult> list = new ArrayList<ITestResult>();

        for (ISuite suite : suites) {          

            Map<String, ISuiteResult> suiteResults = suite.getResults();

            for (ISuiteResult suiteResult : suiteResults.values()) {

                ITestContext testContext = suiteResult.getTestContext();           

                IResultMap passedTests = testContext.getPassedTests();

                IResultMap failedTests = testContext.getFailedTests();

                IResultMap skippedTests = testContext.getSkippedTests();

                IResultMap failedConfig = testContext.getFailedConfigurations();   

                list.addAll(this.listTestResult(passedTests));

                list.addAll(this.listTestResult(failedTests));

                list.addAll(this.listTestResult(skippedTests));

                list.addAll(this.listTestResult(failedConfig));

            }          

        }

        this.sort(list);

        this.outputResult(list, outputDirectory+"/test.txt");

    }

     

    private ArrayList<ITestResult> listTestResult(IResultMap resultMap){

        Set<ITestResult> results = resultMap.getAllResults();    

        return new ArrayList<ITestResult>(results);

    }

     

    private void sort(List<ITestResult> list){

        Collections.sort(list, new Comparator<ITestResult>() {

            @Override

            public int compare(ITestResult r1, ITestResult r2) {

                if(r1.getStartMillis()>r2.getStartMillis()){

                    return 1;

                }else{

                    return -1;

                }              

            }

        });

    }

     

    private void outputResult(List<ITestResult> list, String path){      

        try {

            BufferedWriter output = new BufferedWriter(new FileWriter(new File(path)));

            StringBuffer sb = new StringBuffer();

            for (ITestResult result : list) {

                if(sb.length()!=0){

                    sb.append(" ");

                }

                sb.append(result.getTestClass().getRealClass().getName())

                  .append(" ")

                  .append(result.getMethod().getMethodName())

                  .append(" ")

                  .append(this.formatDate(result.getStartMillis()))

                  .append(" ")

                  .append(result.getEndMillis()-result.getStartMillis())

                  .append("毫秒 ")

                  .append(this.getStatus(result.getStatus()));

            }

            output.write(sb.toString());

            output.flush();

            output.close();

        } catch (IOException e) {          

            e.printStackTrace();

        }

         

    }

     

    private String getStatus(int status){

        String statusString = null;

        switch (status) {      

        case 1:

            statusString = "SUCCESS";

            break;

        case 2:

            statusString = "FAILURE";

            break;

        case 3:

            statusString = "SKIP";

            break;

        default:           

            break;

        }

        return statusString;

    }

     

    private String formatDate(long date){     

       SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

       return formatter.format(date);

    }

}

 

 代码简单易懂，下面给一个测试类：

 

package com.demo;

 

import org.testng.Assert;

import org.testng.annotations.DataProvider;

import org.testng.annotations.Listeners;

import org.testng.annotations.Test;

 

@Listeners({com.demo.NewReport.class})

public class Test15 {

     

    @DataProvider

    public Object[][] dataProvider(){

        return new Object[][]{{1},{2}};

    }

     

    @Test(dataProvider="dataProvider")

    public void testAssert1(int a){

        Assert.assertEquals(1, a);

    }  

     

    @Test

    public void testAssert2(){ 

        Assert.assertEquals("2", "2"); 

    }

 不过这个有有一个改进的地方，如果目录不存在，生成的report 就不OK了
