| 5 * This is a shim for the W3C testharness.js, mapping those of | |
| 6 * its functions that we need to the testing/xpcshell/head.js API. | |
| 7 * See <http://www.w3.org/2008/webapps/wiki/Harness> for documentation. | |
| 8 * This shim does some tests a little differently than the W3C test | |
| 9 * harness; equality comparisons, especially, are less precise. | |
| 10 * The difference does not presently affect any test results. | |
| 11 * | |
| 12 * We use the lower-level do_report_result throughout this file, | |
| 13 * rather than the high-level xpcshell/head.js API that has near | |
| 14 * equivalents for the W3C assert_* functions, because only | |
| 15 * do_report_result allows us to provide Components.stack.caller. | |
