JUnit vs TestNG

JUnit — JUnit is an open-source unit testing framework for Java. It allows developers to write automated tests to validate units of code and quickly identify bugs early in development.

TestNG — TestNG is an open source automated testing framework for Java that builds on JUnit with additional features like annotations, parameters, dependencies, grouping, etc. It allows for data-driven testing

JUnit offers Provides annotations to identify test methods, Provides assertions for testing expected results, Automates running tests and reporting results, Integrates with build tools like Maven and Gradle, while TestNG provides Annotations for defining tests, Test grouping, Parameterization, Dependency management, Parallel test execution.

JUnit stands out for Simplifies writing and running repeatable tests, Encourages following test-driven development, Easy to integrate with continuous integration workflows; TestNG is known for Open source and free, Powerful annotation capabilities, Support for data-driven testing.
