-/**
-  ResizeTestHelper is a framework to test ResizeObserver
-  notifications. Use it to make assertions about ResizeObserverEntries.
-  This framework is needed because ResizeObservations are
-  delivered asynchronously inside the event loop.
-
-  It handles timeouts, and queueing of multiple steps in a test.
-
-  Usage:
-
-  Use createTest() to create tests.
-  Make assertions inside entries, timeout callbacks.
-  Every test should clean up after itself by calling helper.observer.disconnect();
-  Chain tests together with nextTest(), or nextTestRaf()
-
-  Example:
-
-  var helper = new ResizeTestHelper();
-
-  function test0() {
-    helper.createTest(
-      "test0: test name here",
-      setup => { // setup gets called when test starts
-        helper.observer.observe(t3);
-      },
-      entries => { // This is ResizeObserver callback
-        // kick off next test by calling nextTestRaf
-        helper.nextTestRaf();
-      },
-      timeout => { // timeout gets called on timeout
-        // if timeout happens, and timeout is not defined, test will fail
-      }
-    );
