Prototyp

@Test
public void testPlus() {
    System.out.println("plus");
    Vektor that = null;
    Vektor instance = null;
    Vektor expResult = null;
    Vektor result = instance.plus(that);
    assertEquals(expResult, result);
    // TODO review the generated test code and remove the default call to fail.
    fail("The test case is a prototype.");
}Java

Angepasster Prototyp
