  20 Start a debugging session in the Web Inspector and open this file.
  21 <br><br>
  22 Before running the tests please perform the following:
  23 Make sure the execution is not paused in the debugger.<br>
  24 Click the button and when the debugger breaks, set a breakpoint on the first line in the loop
  25 (as indicated by the comment), and click continue.<br>
  26 The debugger should stop at the beggining of the loop.<br>
  27 The above actions should be performed before <b>each</b> of the following tests.
  28 <br><br>
  29 <input type="button" value="run for-in" onclick="runForIn()"/>
  30 <br><br>
  31 TEST 1: Click 'continue'. Execution should continue without stopping on the loop breakpoint again.<br>
  32 TEST 2: Click 'Step over'. Debugger should step inside the loop to the next statement line.<br>
  33 TEST 3: Click 'Step into'. Debugger should step into 'getObject' function.<br>
  34 TEST 4: 'Step over' to the statement line and then 'Step over' again. Debugger should pause on
  35 the for-in loop again.<br>
