Mastering TestNG For Automation - From Basics To Advanced

Ace SDET Automation with TestNG

From Core Concepts to Advanced Frameworks, Parallel Execution & Interview Mastery

Are you preparing for SDET, Automation Engineer, or QA roles and struggling to explain TestNG confidently in interviews or real projects?

Do you know basic TestNG annotations but feel confused when it comes to framework design, parallel execution, retries, listeners, and reports?

This course is designed to fix that gap completely.

What This Course Is About (In Simple Words)

TestNG is not just a testing library — it is the foundation of real-world Java automation frameworks.

In this course, you will learn:

        TestNG from scratch, even if you are a beginner

        How TestNG is used in real automation frameworks

        How interviewers expect you to explain TestNG

        How to handle parallel execution, flaky tests, retries, listeners, and reports

        How TestNG fits into Maven, Jenkins, Selenium, and CI/CD pipelines

This is not a theory-heavy course.
Every concept is explained using real examples, real scenarios, and interview-style explanations.

Why This Course Is Different

Most courses:

        Teach only annotations

        Skip real interview questions

        Do not show how TestNG is used in frameworks

This course:

       Teaches how companies actually use TestNG

       Covers Tier 1 to Tier 5 interview questions

       Builds a complete TestNG-based automation framework

       Explains concepts in very simple, layman-friendly language

You will learn what to write, why to write it, and how to explain it confidently in interviews.
