@Disabled for skipping tests in JUnit - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the purpose of the @Disabled annotation in JUnit?

The <code>@Disabled</code> annotation is used to skip or ignore a test method or class temporarily. It prevents the test from running without deleting or commenting out the code.

beginner

How do you disable a single test method using JUnit?

Add the @Disabled annotation directly above the test method. For example:<br>

@Disabled<br>@Test<br>void testExample() { ... }

Can you disable an entire test class in JUnit? How?

Yes, by placing the <code>@Disabled</code> annotation above the class declaration, all tests inside that class will be skipped during execution.

What happens to the test report when tests are skipped using @Disabled?

Skipped tests are reported as 'skipped' or 'ignored' in the test report. They do not count as passed or failed but are noted so you know they were intentionally not run.

beginner

Why might you want to use @Disabled instead of deleting a test?

Using @Disabled keeps the test code for future use or debugging. It allows you to temporarily skip tests that are flaky, incomplete, or dependent on external factors without losing the test logic.

What does the @Disabled annotation do in JUnit?

A Runs the test multiple times

B Marks the test as failed

C Enables the test to run only on weekends

D Skips the annotated test method or class

The @Disabled annotation tells JUnit to skip the test method or class during execution.

Where do you place the @Disabled annotation to skip a test method?

A In the test class constructor

B Inside the test method body

C Above the test method declaration

D Below the test method declaration

You place @Disabled directly above the test method declaration to skip that specific test.

If you want to skip all tests in a class, what should you do?

A Add <code>@Disabled</code> above the class declaration

B Add <code>@Disabled</code> to each test method

C Delete the test class

D Rename the test class

Adding @Disabled above the class disables all tests inside that class.

How are skipped tests shown in the test report?

A As failed tests

B As skipped or ignored tests

C As passed tests

D They are not shown at all

Skipped tests appear in the report as skipped or ignored, so you know they were intentionally not run.

Why is it better to use @Disabled instead of deleting a test?

A To keep the test code for future use

B To make the test run faster

C To automatically fix test errors

D To run the test on a different machine

@Disabled keeps the test code intact so you can enable it later or debug it.

Explain how and why you would use the @Disabled annotation in JUnit testing.

Think about situations when you want to skip tests without deleting them.

Describe the impact of using @Disabled on test reports and test suite results.

Consider how test reports show tests that were not executed.
