Flexible Test
^^^^^
**Definition:**

* Test code verifies different functionality depending on when or where it is run.


**Code Example:**

.. code-block:: java

  public void testDisplayCurrentTime_whenever() {
    // fixture setup
    TimeDisplay sut = new TimeDisplay();

    // exercise SUT
    String result = sut.getCurrentTimeAsHtmlFragment();

    // verify outcome
    Calendar time = new DefaultTimeProvider().getTime();
    StringBuffer expectedTime = new StringBuffer();
    expectedTime.append("<span class=\"tinyBoldText\">");

    if ((time.get(Calendar.HOUR_OF_DAY) == 0)
    && (time.get(Calendar.MINUTE) <= 1)) {
      expectedTime.append( "Midnight");
    } else if ((time.get(Calendar.HOUR_OF_DAY) == 12)
      && (time.get(Calendar.MINUTE) == 0)) { // noon
      expectedTime.append("Noon");
    } else {
      SimpleDateFormat fr = new SimpleDateFormat("h:mm a");
      expectedTime.append(fr.format(time.getTime()));
    }
    expectedTime.append("</span>");
    assertEquals( expectedTime, result);
  }
