Hello Rspecers,
I have a rails project where I am calling Resolv::DNS.open and then
using the block to check a domain name.
The code snippet in question is:
domain = "mytest.com"
Resolv::DNS.open do |dns|
@mx = dns.getresources(domain, Resolv::DNS::Resource::IN::MX)
end
I obviously want to stub this out, especially for speed but can''t
quite work out how.
I have done:
>From what I can tell, Resolv::DNS first is receiving :open and it will
then be yielding instances of Resolv::DNS to be using inside the
block.
So, my last unsuccessfull attempt at mocking this out is:
@dns = mock(Resolv::DNS)
Resolv::DNS.should_receive(:open).and_return([@dns])
@dns.should_receive(:getresources).and_return("MX Record")
The errors I am getting are not about mocks receiving unexpected
messages. The :open message mock gets called. The second one (on
@dns.should_receive(:getresources) also does not complain.
But @mx in the above code ends up as nil, when I would think it should
end up as "MX Record".
Any pointers?
Regards
Mikel
