What is TestNG

Overview

TestNG is an open-source testing framework for Java, built to overcome limitations of older frameworks like JUnit, with richer annotations and configuration options.

Core Features

• Annotation-based test lifecycle control (setup, execution, teardown).
• Support for grouping related tests together.
• A configuration file (testng.xml) to control which tests run and how.
• Built-in assertions and detailed pass/fail reporting.

Typical Use

Testers write test methods annotated with @Test, organize them into suites via testng.xml, and run the suite to get a structured report of results.
