54     * Calls to AddTestCase here. AddTestCase is a function that is defined
55     * in shell.js and takes three arguments:
56     * - a string representation of what is being tested
57     * - the expected result
58     * - the actual result
59     *
60     * For example, a test might look like this:
61     *
62     * var zip = /[\d]{5}$/;
63     *
64     * AddTestCase(
65     * "zip = /[\d]{5}$/; \"PO Box 12345 Boston, MA 02134\".match(zip)",   // description of the test
66     *  "02134",                                                           // expected result
67     *  "PO Box 12345 Boston, MA 02134".match(zip) );                      // actual result
