I was about to take your advice, when I discovered another problem:
======
RSpec.configure do |config|
config.mock_with :rspec
config.before(:each, :geocoding => nil) do
Geocoding.stub(:client).and_return(Geocoding::StubGeoClient.new)
end
end
======
Since the test-specific before-all hook runs first before the global
before-each hook, that means that the `expensive` operation now hits
an external geocoding service, which makes it take even longer. It
also makes tests fail because WebMock is running, and it prohibits
network connections you don't explicitly specify.
The fact that this is becoming obnoxious suggests that something else
is probably bad (e.g. maybe the `expensive` model should be changed to
be less expensive to create). I think I'll do that instead of trying
to go down this road further. Thanks for your help, David.
