	 *
	 * @depends test_js_no_ampersands
	 *
	 * The previous test confirms that no ampersands exist in src/wp-includes/js/wp-embed.js.
	 * However, we must also confirm that UglifyJS does not add ampersands during its
	 * optimizations (which we tweak to avoid, but indirectly -- understandably, there's
	 * no "don't add ampersands to my JavaScript file" option).
	 *
	 * So this test checks for ampersands in build/wp-includes/js/wp-embed.min.js.
	 * In many cases, this file will not exist; in those cases, we simply skip the test.
	 *
	 * So when would it be run? We have Travis CI run `npm run test` which then runs, in order,
	 * `qunit:compiled` (which runs the build) and then `phpunit`. Thus, this test will at least be
	 * run during continuous integration.
	 *
	 * However, we need to verify that `qunit:compiled` runs before `phpunit`. So this test also
	 * does a cheap check for a registered Grunt task called `test` that contains both
	 * `qunit:compiled` and `phpunit`, in that order.
	 *
	 * One final failsafe: The Gruntfile.js assertion takes place before checking for the existence
	 * of wp-embed.min.js. If the Grunt tasks are significantly refactored later, it could indicate
	 * that wp-embed.min.js doesn't exist anymore. We wouldn't want the test to silently become one
	 * that is always skipped, and thus useless.
