title: No tests found with test runner JUnit 4
body: <p>I have a JUnit test case that I am trying to use but it is giving me the error "No tests found with test runner JUnit 4". Yes, I have looked at that other one on here that asks the same thing but that does not work for me. My tests are already named by starting with "test"</p>
  
  <p>Does anyone know how to fix this? Here is my test class</p>
  
  <pre><code>package testing;
  
  import static org.junit.Assert.*;
  import org.junit.Test;
  
  public class cubeTest {
  
  
      public void testCube(){
          shape3D.Cube cube = new shape3D.Cube(2);
          assertTrue(cube.getVolume() == 8);
          assertTrue(cube.getSurfaceArea() == 24);
      }
      public void testCube1(){
          shape3D.Cube cube = new shape3D.Cube(4);
          assertTrue(cube.calculateVolume() == 64);
          assertTrue(cube.calculateSurfaceArea() == 96);
      }
      public void testCube2(){
          shape3D.Cube cube = new shape3D.Cube(3);
          assertTrue(cube.getVolume() == 27);
          assertTrue(cube.calculateSurfaceArea() == 54);
      }
  
  
  }
  </code></pre>
