Do you really need a full render view test harness here, or could you just make
do with simulating the different tab events and using a test browser context?

Then, you could use a TestBrowserThreadBundle with IO_MAINLOOP (which can't be
used with RenderViewHostTestHarness), which would make any cross-thread testing
here MUCH easier since then the IO thread and the UI thread would use the same
MessageLoop, meaning that you could just call RunUntilIdle() and that would
cover both IO and UI threads.

Yes, because it uses ChromeRenderViewHostTestHarness::web_contents

  public:
   using ChromeRenderViewHostTestHarness::web_contents;
 
   DataUseUITabModel* data_use_ui_tab_model() {
+    DataUseUITabModel* data_use_ui_tab_model = data_use_ui_tab_model_private();
+    base::RunLoop().RunUntilIdle();

[sclittle, 2015/11/24 23:07:37]

Why is this here? This shouldn't need to be here.

[tbansal1, 2015/11/25 20:55:16]

Done.

[sclittle, 2015/11/24 23:07:37]

None of these objects actually live on the IO thread, they all live here on the
UI thread. This doesn't test any of the different thread stuff between the
objects.

You could either switch over to using an IO_MAINLOOP test setup like my comment
above (probably easier), or actually simulate this with a real IO thread
(probably harder).

For example, the TabIdAnnotator test uses a real IO thread by passing around a
base::RunLoop for the UI thread, and posting a Quit task to it later.

I need the ability to use web_contents, that;s why
ChromeRenderViewHostTestHarness.
