Why Retry analyzer for failures in Selenium Java? - Purpose & Use Cases

The Big Idea

What if your tests could fix themselves when they fail the first time?

The Scenario

Imagine you run your automated tests on a website, but sometimes tests fail because of slow loading or temporary glitches.

You have to rerun all tests manually to check if failures are real or just random hiccups.

The Problem

Manually rerunning tests is slow and boring.

You might miss flaky failures or waste time rerunning tests that actually passed.

This causes delays and frustration in delivering quality software.

The Solution

A retry analyzer automatically reruns failed tests a set number of times.

This helps catch temporary issues without manual effort.

You get more reliable test results faster.

Before vs After

✗ Before

if(testFailed) {
  rerunTest();
}

✓ After

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

public class Retry implements IRetryAnalyzer {
  private int retryCount = 0;
  private int maxRetry = 3;

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

What It Enables

It enables automatic handling of flaky tests, making your test suite more stable and trustworthy.

Real Life Example

When testing a shopping site, network delays cause some tests to fail randomly.

Retry analyzer reruns those tests automatically, so you only fix real bugs, not temporary glitches.

Key Takeaways

Manual reruns waste time and cause errors.

Retry analyzer automates reruns for failed tests.

This improves test reliability and speeds up feedback.
