It's very mysterious to me that revisionDetails.$.fullyProcessedRevision doesn't
work. There's something I'm not understanding. :( Doesn't need to block landing
the patch though.

Beats me, but you will notice there are no other test files that do it.

+    equal(revisionDetails.shadowRoot.querySelector('#trunkRevision'), null);
+    start();
+  });
+});
+
+asyncTest("basic", 2, function() {
+  var revisionDetails = document.createElement('ct-revision-details');
+
+  var builderRevisions = CTBuilderRevisionsMock();
+  var commitLog = CTCommitLogMock();
+  commitLog._findFirstAndLastRevisions('blink');

Should CTCommitLogMock be the one doing this? Seems to me like a commit log that
hasn't already called this is in an invalid state.

Doing it in CTCommitLogMock breaks ct-commit-list: basic. It relies on behavior
in CTCommitLog.prototype.range which is gated by firstRevision. I think it's a
kind of crappy test.

+
+  revisionDetails.builderLatestRevisions = builderRevisions;
+  revisionDetails.tree = 'blink';
+  revisionDetails.revisionLog = commitLog;
+
+  requestAnimationFrame(function() {
+      equal(revisionDetails.shadowRoot.querySelector('#fullyProcessedRevision').innerText, '158543');
+      equal(revisionDetails.shadowRoot.querySelector('#trunkRevision').innerText, '158545');
+      start();
+  });
+});
+
+})()
