+<p>To test, open the DevTools (Ctrl+Shift+I) and reload the page.
+<br><br>
+Before running the tests please perform the following:
+Make sure the execution is not paused in the debugger.<br>
+Click the button and when the debugger breaks, set a breakpoint on the first line in the loop
+(as indicated by the comment), and click continue.<br>
+The debugger should stop at the beggining of the loop.<br>
+The above actions should be performed before <b>each</b> of the following tests.</p>
+<br><br>
+<input type="button" value="run for" onclick="runFor()"/>
+<br><br>
+TEST 1: Click 'continue'. Execution should continue without stopping on the loop breakpoint again.<br>
+TEST 2: Click 'Step over'. Debugger should step inside the loop to the next statement line.<br>
+TEST 3: Click 'Step into'. Debugger should step into 'initialize' function. Click 'Step into' until
+outside of the 'initialize' function - debugger should enter the 'condition' function.<br>
