After developing a automation framework,now a automation tester want to reduce a false positive rate,so he/she will use immediate rerun of failed test case for reducing the failed test due to setup and network problem.

Below is the code for same:

Using the below logic you can immediate rerun your failed test case.
package com.companyName.web.utils;

import org.testng.IRetryAnalyzer;
import org.testng.ITestResult;

public class Retry implements IRetryAnalyzer{
private int retryCount = 0;
private int maxRetryCount = 3;
public boolean retry(ITestResult result) {

if(retryCount < maxRetryCount) { retryCount++; return true; } return false; } }

2) use below annotation in your test program
@Test(groups="groupName",retryAnalyzer=Retry.class)
if you are not using group then use this
@Test(retryAnalyzer=Retry.class)
