33 LayoutTestController class:
34 Bound to a JavaScript window.layoutTestController object using the
35 CppBoundClass::bindToJavascript(), this allows layout tests that are run in
36 the test_shell (or, in principle, any web page loaded into a client app built
37 with this class) to control various aspects of how the tests are run and what
38 sort of output they produce.
