25.8. Common JUnit Annotations

Try these first

1. 1.

   What does the @Test annotation do?

   Hint

   Think about how JUnit knows what to run.

2. 2.

   What is the purpose of @Disabled?

   Hint

   Consider how you would mark a test that isn’t ready.

3. 3.

   What does the @Test annotation signify?

   • To skip tests
   • To define a test
   • To clean up resources

   Hint

   This is the core annotation for creating unit tests.

4. 4.

   True or False: The @AfterEach annotation runs after each test method.

   • True
   • False

   Hint

   Consider the lifecycle of the test method.

5. 5.

   Create a JUnit test class for a library system where you manage book loans. Use both @BeforeAll and @AfterAll to handle setup and teardown processes, and demonstrate usage of other annotations.

   Hint

   Think of how sections of your library can share the same resources.

6. 6.

   Describe a scenario in your ongoing project where using @Disabled would be appropriate and explain your reasoning.

   Hint

   Consider times when you are actively coding a feature and tests don't reflect the current state.
