40 * Calls to AddTestCase here. AddTestCase is a function that is defined

42 * - a string representation of what is being tested
43 * - the expected result
44 * - the actual result
45 *
46 * For example, a test might look like this:
47 *
48 * var zip = /[\d]{5}$/;
49 *
50 * AddTestCase(
51 * "zip = /[\d]{5}$/; \"PO Box 12345 Boston, MA 02134\".match(zip)", // description of the test
52 * "02134", // expected result
53 * "PO Box 12345 Boston, MA 02134".match(zip) ); // actual result
