EXPECT_CALL(_http, post(testing::_, testing::_, testing::_)).WillOnce(testing::Invoke(Argument<2>.complete(200, ""));

My idea is to invoke a function complete(int, string) on the 3rd argument passed in post call. 

Could anyone help?

The simplest solution is to use a lambda in the Invoke call.

EXPECT_CALL(_http, post(testing::_, testing::_, testing::_)).WillOnce(testing::Invoke(
    [] (Arg1 arg1, Arg2 arg2, Arg3 arg3) { arg2.complete(200, ""); }));
 
When the builtin actions don't do what you need, a lambda is a good escape hatch.

Thanks Samuel.

I modified my EXPECT_CALL as :

EXPECT_CALL(_http, post(testing::_, testing::_, testing::_))
   .WillOnce(testing::WithArg<2>(testing::Invoke(
[] (const std::shared_ptr <HttpCallback> &callback)
{
callback->complete(200, "");
})));

and it worked.
