TestNG Framework

What is TestNG?

TestNG ("Test Next Generation") is a Java testing framework inspired by JUnit, designed with more powerful features for organizing, configuring, and reporting on automated tests.

Key Capabilities

• Flexible test configuration via annotations.
• Grouping and prioritizing tests.
• Data-driven testing via @DataProvider.
• Parallel test execution.
• Built-in HTML test reports.

Why It's Popular for API and UI Automation

TestNG integrates smoothly with tools like Rest Assured and Selenium, providing the structure (setup, teardown, assertions, reporting) needed to build a full automated test suite.
