IRetryAnalyzer

 IRetryAnalyzer:- 

IRetryAnalyzer is an interface in TestNG that allows you to programmatically retry failed tests during        the same test execution.

You implement the retry() method to specify the conditions for retrying a test.

Use IRetryAnalyzer to handle transient failures dynamically.

Run testng-failed.xml as a follow-up to catch any persistent issues.

Which One to Use?

Scenario	Recommendation
Large test suite	Run testng-failed.xml
Debugging failed tests after run	Run testng-failed.xml
Handling flaky tests automatically	Use IRetryAnalyzer
Continuous Integration (CI) setup	Use IRetryAnalyzer

//ClassA

package TestNG;

import java.util.List;

import org.openqa.selenium.By;

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.WebElement;

import org.openqa.selenium.chrome.ChromeDriver;

import org.testng.Assert;

import org.testng.annotations.Test;

public class ClassA {

@Test

public void testCase1() {

System.out.println("This is test case1");

Assert.assertTrue(false);

}

@Test

public void testCase2() {

System.out.println("This is test case2");

Assert.assertTrue(true);

}

}

//classB

package TestNG; import org.testng.Assert; import org.testng.annotations.Test; public class ClassB { @Test public void testCase3() { System.out.println("This is test case3"); Assert.assertTrue(true); } @Test public void testCase4() { System.out.println("This is test case4"); Assert.assertTrue(true); } }

//ClassC

package TestNG; import java.util.ArrayList; import java.util.List; import org.testng.TestNG; import org.testng.annotations.AfterTest; public class ClassC { @AfterTest public void runFailedTestCases() { TestNG object = new TestNG(); List <String> list = new ArrayList<String>(); list.add("D:\\TableAutomation\\test-output\\Suite\\testng-failed.xml"); object.setTestSuites(list); object.run(); } }
