Is there a way around creating the real AutofillManagerDelegate here?

[Ilya Sherman, 2013/06/20 00:07:16]

You can probably use
components/autofill/browser/test_autofill_manager_delegate.h here.

[blundell, 2013/06/21 12:55:23]

Done.

My understanding is that I can't change this to be at the content level until
this test is no longer in unit_tests (in fact, I tried, and got a crash).

[Ilya Sherman, 2013/06/20 00:07:16]

Yeah, that seems to be what Jói concluded as well.

nit: "MockAutofillManager"

[blundell, 2013/06/21 12:55:23]

Done.

[Ilya Sherman, 2013/06/20 00:07:16]

nit: Since this code is in the autofill namespace already, no need for
"autofill::"

[blundell, 2013/06/21 12:55:23]

Done.

[Ilya Sherman, 2013/06/20 00:07:16]

note: If you take my advice about creating a subclass of AutofillDriverImpl for
testing, you can wire this up in the constructor.

[blundell, 2013/06/21 12:55:23]

Done.

[blundell, 2013/06/19 17:49:37]

I had made this a scoped ptr but got complaints about the destructor being
private.

[Ilya Sherman, 2013/06/20 00:07:16]

Please create a "class TestAutofillDriverImpl : public AutofillDriverImpl { ...
}" that has a public destructor and use a scoped_ptr here.

[blundell, 2013/06/21 12:55:23]

Done.

+
+TEST_F(AutofillDriverImplTest, SetExternalDelegate) {
+  EXPECT_CALL(*autofill_manager_, SetExternalDelegate(NULL));
+  driver_->SetAutofillExternalDelegate(scoped_ptr<AutofillExternalDelegate>());

[Ilya Sherman, 2013/06/20 00:07:16]

Hmm, this is testing deprecated functionality, i.e. the non-native UI, which is
going away soon.  I'd prefer not to add a test that we expect to fail quite soon
;)

[blundell, 2013/06/21 12:55:23]

Replaced this test with tests to test response to frame navigation.
