(sorry - I'll update that doc where this was taken from)

[Bret, 2017/02/01 02:21:46]

Done. I took it from the collected cookies version actually; updated there too.

unused?

Oops yeah. Removed.

I think this can be merged into the above test harness (unless we want another
test case for non-MD, but I'd probably skip that). (the approach here is useful
when there's an existing browser_test harness that's being adapted, but that's
not the case for this one)

Done.

nit: add a comment (I try to ensure every TEST_F has a comment above it
describing why the test exists). For these, I've been doing things like

// Calls ShowDialog("default"). Interactive when run via browser_tests
--gtest_filter=BrowserDialogTest.Invoke --interactive
--dialog=HungRendererDialogViewBrowserTest.InvokeDialog_default.

[Bret, 2017/02/01 02:21:46]

I don't like the idea of baking the invocation into the comment. How's this?

+                       InvokeDialog_default) {
+  RunDialog();
+}
