Description

Hello,

I created a simple class.

public class Example  {

    public static void main(String[] args) {
        var color = new Example();
        System.out.println(color.isTextBlack("black"));
        System.out.println(color.isTextBlack("white"));
    }

    public boolean isTextBlack(String color) {
        return color.equals("black");
    }
}

Then I create a JUnit 5 test via a "bulb" on the class line.

A file with this code will be generated.

import org.junit.jupiter.api.AfterEach;
import org.junit.jupiter.api.AfterAll;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.BeforeAll;
import org.junit.jupiter.api.Test;
import static org.junit.jupiter.api.Assertions.*;

public class ExampleTest {
    
    public ExampleTest() {
    }
    
    @BeforeAll
    public static void setUpClass() {
    }
    
    @AfterAll
    public static void tearDownClass() {
    }
    
    @BeforeEach
    public void setUp() {
    }
    
    @AfterEach
    public void tearDown() {
    }

    /**
     * Test of main method, of class Example.
     */
    @Test
    public void testMain() {
        System.out.println("main");
        String[] args = null;
        Example.main(args);
        // TODO review the generated test code and remove the default call to fail.
        fail("The test case is a prototype.");
    }

    /**
     * Test of isTextBlack method, of class Example.
     */
    @Test
    public void testIsTextBlack() {
        System.out.println("isTextBlack");
        String color = "";
        Example instance = new Example();
        boolean expResult = false;
        boolean result = instance.isTextBlack(color);
        assertEquals(expResult, result);
        // TODO review the generated test code and remove the default call to fail.
        fail("The test case is a prototype.");
    }
}

If I run it, it will crash with this error

If I delete the file and create Junit 4 (see the picture above), the same code will be generated, only with the import of other libraries.

import org.junit.After;
import org.junit.AfterClass;
import org.junit.Before;
import org.junit.BeforeClass;
import org.junit.Test;
import static org.junit.Assert.*;

JUnit 4 works without any problems. The mystery is that if I now delete the file and create JUnit 5, JUnit4 will be created again.

Anyway, JUnit5 is unusable.

Please repair.

Thank you
