Exam.should_receive(:by_created_at_and_not_archived).and_return(
double('startkey').tap {|startkey|
startkey.should_receive(:startkey).with([@exam.created_at]).and_return(
double('endkey').tap {|endkey|
endkey.should_receive(:endkey).with(['0']).and_return(
double('limit').tap {|limit|
limit.should_receive(:limit).with(2).and_return([@exam1, @exam2])
}
)
}
)
}
)
LOL, this is the ugliest code I've written all year. You'd might want to use
variables for readability:
endkey = double('endkey')
startkey = double('startkey')
startkey.should_receive(:start key).with([@exam.created_at]) { endkey }
