What are the types of TestNG listeners in Selenium WebDriver?

As an experienced tutor registered on UrbanPro.com, let's embark on a journey through the enchanting world of TestNG listeners in Selenium WebDriver. These listeners orchestrate the test execution lifecycle, providing automation testing professionals with the ability to customize and enhance their testing experience.

1. Overview of TestNG Listeners

- Introduction:

• Explanation:
  • TestNG listeners are event-driven interfaces that allow testers to intervene in the test execution lifecycle. They provide a way to perform actions before and after certain events, such as test start, test success, test failure, etc.

2. Types of TestNG Listeners in Selenium WebDriver

- 1. ITestListener

- Overview:

• Explanation:
  • ITestListener is a fundamental listener interface in TestNG. It captures events related to test execution.

- Key Events Captured:

• Events:
  • onStart: Triggered when the test suite starts.
  • onTestStart: Triggered before each test method starts.
  • onTestSuccess, onTestFailure, onTestSkipped: Triggered based on test outcomes.
  • onFinish: Triggered when the test suite finishes.

- 2. ISuiteListener

- Overview:

• Explanation:
  • ISuiteListener captures events related to the entire suite's lifecycle.

- Key Events Captured:

• Events:
  • onStart: Triggered when the suite starts.
  • onFinish: Triggered when the suite finishes.

- 3. IInvokedMethodListener

- Overview:

• Explanation:
  • IInvokedMethodListener captures events related to individual test method invocations.

- Key Events Captured:

• Events:
  • beforeInvocation: Triggered before a test method is invoked.
  • afterInvocation: Triggered after a test method is invoked.

- 4. IReporter

- Overview:

• Explanation:
  • IReporter allows custom reporting by generating test results in a desired format.

- Key Events Captured:

• Events:
  • generateReport: Triggered to generate the test report.

- 5. IAnnotationTransformer

- Overview:

• Explanation:
  • IAnnotationTransformer allows modification of annotations on test methods or classes.

- Key Events Captured:

• Events:
  • transform: Triggered to transform annotations.

3. Practical Implementation of TestNG Listeners

- Example: Implementing ITestListener

- Example: Implementing ISuiteListener
