In the test above the case for doWrapOffTest() still uses setLineWrap(true) which disable scroll bar, if you drop it the scrollbar will be visible.
  
As of the height, you need to read the value a little bit later, not immediately after "frame.setVisible", for example if you read these values at lines 75,76 you will get something like that:
textArea.getHeight() = 3216
textArea1.getHeight() = 1616
