void method unit test java

Comment

// The JUnit FAQ has a section on testing methods that return void. 
// In your case, you want to test a side effect of the method called.

// The example given in the FAQ tests that the size of a Collection changes 
// after an item is added.

@Test
public void testCollectionAdd() {
    Collection collection = new ArrayList();
    assertEquals(0, collection.size());
    collection.add("itemA");
    assertEquals(1, collection.size());
    collection.add("itemB");
    assertEquals(2, collection.size());
}
