Example:

 /** * Test normal sentence */ @Test public void testGetNumberOfCharsNormalWithSpaces() { int expected = 11; SplitStats stats = new SplitStats( "I am hungery."); assertEquals(expected, stats.getNumberOfChars() ); } /** * Test normal sentence with tabs */ @Test public void testGetNumberOfCharsWithTabs() { int expected = 11; SplitStats stats = new SplitStats( "I\tam\thungery."); assertEquals(expected, stats.getNumberOfChars() ); } 

Im just confused as to what I have to write in the JUnit class.
