If you change launchContentShellWithUrl to return a ContentShellActivity, this
shouldn't be necessary.

Nor the cast below.

Done.

+        // Make sure that the URL is set as expected.
+        ContentShellActivity contentShellActivity = (ContentShellActivity) activity;
+        assertEquals(URL,
+                contentShellActivity.getActiveShellView().getContentView().getUrl());
+    }
+}
