Retrying Failed TestNG Testcases

When the test run is complete, we can retry failed Tests From testng-failed.xml

After a TestNG run, it automatically generates:

You can run this file to execute only failed tests.

TestNG provides an interface called TestNG IRetryAnalyzer that allows you to rerun failed tests automatically.

import org.testng.IRetryAnalyzer;

import org.testng.ITestResult;



public class RetryFailed implements IRetryAnalyzer {

     private int retry_count=0;

     private int retry_maxcount=2;




     @Override

     public boolean retry(ITestResult result) {

          if(retry_count < retry_maxcount) {

              retry_count++;

              return true;

          }

          return false;

     }

}

Test class

Test class that uses the retry mechanism.

import org.testng.Assert;

import org.testng.annotations.Test;




public class TestNGRetryFailedCases {

    

     @Test(retryAnalyzer=RetryFailed.class)

     public void failedTest() {

          System.out.println("Test execution ...");

          Assert.assertTrue(false); // force failure

     }

}
