	 * @var string[] list of folders and files to skip. We want to avoid
	 *               loading PHP files from the vendor folder since that's
	 *               not our code. ParserIntegrationTest is a complex suite
	 *               that we can't handle in the usual way, so we will add
	 *               that to a suite on its own, manually, as required.
	 *               Likewise `LuaSandbox\\SandboxTest` from the Scribunto
	 *               extension is a dynamic suite that generates classes
	 *               during `--list-tests-xml` which we can't run on their
	 *               own. We skip it in the scan and add it manually back
	 *               later.
	 *               `LuaEngineTestSkip` is an empty test case
	 *               generated by Scribunto's dynamic test suite when a
	 *               particular Lua engine isn't available. Since this is
	 *               just an empty test suite with a skipped test, we can
	 *               filter this from the list of test classes.
