Automaters: Full Stack QA_SDET: How to rerun only failed test cases using testng in automation testing framework? TestNG listeners for Automation Framework

1. Create a class which implements IRetryAnalyzer and provide the retry count @maxRetryCount

public class FailRetry implements IRetryAnalyzer {

private int retryCount = 0;
private static final int maxRetryCount = 2;

@Override
public boolean retry(ITestResult result) {
    if (retryCount < maxRetryCount) {
      retryCount++;
      return true;
    }
    return false;
}
}

2. Create a class which implements IAnnotationTransformer and pass the class name that we have created in step-1 @setRetryAnalyzer

public class RetryListener implements IAnnotationTransformer {

    @Override
    public void transform(ITestAnnotation testannotation, Class testClass,
            Constructor testConstructor, Method testMethod)    {
        IRetryAnalyzer retry = testannotation.getRetryAnalyzer();

        if (retry == null)    {
            testannotation.setRetryAnalyzer(FailRetry.class);//pass the class name created in Step-1
        }

    }
}

3. Add listener in testng.xml file after the suite tag as below and define the class name created in Step-2 with the package path

<suite name="Automation Test Suite for IX Onespace">
<listeners>
        <listener class-name="com.task.automation.util.RetryListener"/>
</listeners>
