In JUnit 5, you can disable a test by annotating it with @Disabled from the org.junit.jupiter.api package.

Disable a Single Test Method

import org.junit.jupiter.api.Disabled;
import org.junit.jupiter.api.Test;

class CalculatorTest {

    @Test
    @Disabled
    void divisionByZeroTest() {
        // This test will be skipped
    }
}

When you run the test suite, this test will not be executed.

Add a Reason

It is a good practice to include a reason so other developers know why the test is disabled.

import org.junit.jupiter.api.Disabled;
import org.junit.jupiter.api.Test;

class CalculatorTest {

    @Test
    @Disabled("Temporarily disabled until division-by-zero handling is fixed")
    void divisionByZeroTest() {
        // This test will be skipped
    }
}

Disable an Entire Test Class

You can also place @Disabled on a test class to skip all tests inside it.

import org.junit.jupiter.api.Disabled;
import org.junit.jupiter.api.Test;

@Disabled("Disabled while refactoring the calculator module")
class CalculatorTest {

    @Test
    void additionTest() {
        // This test will be skipped
    }

    @Test
    void subtractionTest() {
        // This test will also be skipped
    }
}

Summary

Use:

@Disabled

or preferably:

@Disabled("Reason why this test is disabled")

The required import is:

import org.junit.jupiter.api.Disabled;

@Disabled is useful for temporarily skipping tests that are incomplete, unstable, or depend on functionality that is not ready yet.
