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.
