How does JUnit support automation?

JUnit allows tests to be run automatically during builds or continuous integration, ensuring code quality without manual effort.

intermediate

What role does JUnit play in Test-Driven Development (TDD)?

JUnit enables TDD by letting developers write tests before code, ensuring code meets requirements from the start.

beginner

Name two features of JUnit that make it popular.

1. Easy integration with IDEs and build tools. 2. Clear and simple annotations for writing tests.

What is a key reason JUnit is widely used in Java testing?

A It is the only testing framework available

B It only works with web applications

C It is simple and integrates well with tools

D It requires no coding knowledge

JUnit is popular because it is simple and integrates well with many Java tools and IDEs.

Which of these is NOT a feature of JUnit?

A Provides a graphical user interface for tests

B Supports automated testing

C Uses annotations to mark test methods

D Integrates with build tools like Maven

JUnit does not provide a graphical user interface; it runs tests via code and reports results.

How does JUnit help in Test-Driven Development?

A By allowing tests to be written before code

B By generating code automatically

C By replacing the need for tests

D By running tests only after deployment

JUnit supports TDD by letting developers write tests first, guiding code development.

Which tool commonly integrates with JUnit for continuous testing?

A Slack

B Photoshop

C Excel

D Maven
