| * - the expected result |
| * - the actual result |
| * |
| * For example, a test might look like this: |
| * |
| * var zip = /[\d]{5}$/; |
| * |
| * AddTestCase( |
| * "zip = /[\d]{5}$/; \"PO Box 12345 Boston, MA 02134\".match(zip)", // description of the test |
| * "02134", // expected result |
| * "PO Box 12345 Boston, MA 02134".match(zip) ); // actual result |
