Benefits of JUnit Framework

Some of the benefits are as follows:

Automated Unit Testing: JUnit allows for the automatic execution of tests, improving efficiency and reducing human error.

Continuous Integration: JUnit is commonly used in CI/CD pipelines, ensuring code quality is maintained through constant testing.
