How to always fail a Junit Java Test Case

If you want to always intentionally fail a Java Junit test case then make use of the static fail() method from the org.junit.jupiter.api.Assertions class.

import static org.junit.jupiter.api.Assertions.fail;


public class TestJunit {

    @Test
    public void failTest() {
        System.out.println("hello there!");
        fail("This case will always fail!");
    }
}

org.opentest4j.AssertionFailedError: This case will always fail!
