This article introduces the implementation of TestNG-TestListenerAdapter and IReporter, the content is very detailed, interested friends can refer to, hope to be helpful to you.

Https://static.javadoc.io/org.testng/testng/6.13/org/testng/TestListenerAdapter.html

TestListenerAdapter is a simple ITestListener adapter that stores all running tests. You can retrieve these results using the following methods: getPassedTests () getFailedTests () getSkippedTests () if you extend this class to override any of these methods, remember to call their super equivalents if you want to maintain this test list. The IReporter client can implement this interface to generate reports. Its method generateReport () will be called after all suites are run, and the parameters will provide all the test results that occur during that run.

What is the IReporter interface for? Is to let users customize the report, many people want to customize the report, so look for various plug-ins, such as testng-xslt, reportng, various configurations, the final result, can not be customized, but why can not customize

How about making one? Testng's IReporter interface takes over such a function. We only need to implement this interface and add snooping to it.

Now that you can get all the information, you can save it in the database, or generate a html yourself, or write it in EXCEL.

Wait, wait, wait. Here's how to implement the IReporter interface:

Custom report

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 xmlSuites, List suites, String outputDirectory) {List list = new ArrayList (); for (ISuite suite: suites) {Map 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 listTestResult (IResultMap resultMap) {Set results = resultMap.getAllResults (); return new ArrayList (results) } private void sort (List list) {Collections.sort (list, new Comparator () {@ Override public int compare (ITestResult R1, ITestResult R2) {if (r1.getStartMillis () > r2.getStartMillis ()) {return 1;} else {return-1 }});} private void outputResult (List 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 (" millisecond ") .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);}}

Generate test report

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");}} so much about the implementation of TestNG-TestListenerAdapter and IReporter. I hope the above content can be helpful to you and learn more knowledge. If you think the article is good, you can share it for more people to see.
