java分享第十九天（TestNg的IReporter接口的使用）

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("\r\n");
                }
                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");
    }
}

运行后，大家打开test-output文件夹，看是不是多了个test.txt的文件夹。
