why SetArgReferee raise a Warninig: no return statement

[Yongbo Zou]

When compiled, it raises a warning: no return statement

class ncACSDBMock: public ncIACSDB

{

        MOCK_METHOD2(GetCustomPerm, bool(const dbCustomPermInfo&, dbCustomPermInfo&));

}

TEST_F (ut_ncACSProcessor, IsGetCustomPermInfosWorks)

{

       EXPECT_CALL(*_acsdbMock, GetCustomPerm (_,_))

.WillOnce(SetArgReferee<1>(info));

}

Here are the details:

Can someone tell me why?

It does so for a perfectly good reason.
The method you're trying to mock has a bool return value but you're
not returning anything from your mocked method.

Try something like this:
.WillOnce(DoAll(SetArgReferee<1>(info),Return(true)));
