stub_request chain to_return from array of files

Question

i have an array of raw_responses using web_mock i want use them as args of to_return method and chain to stub_request method:

#["file1.txt", "subfolder/file_n.txt", "awsome_name.txt"]
rr = Dir.glob(File.expand_path("../../markups/*.txt", __FILE__))
stub_request(:get, "www.google.de").to_return(rr[0]).to_return(rr[1]).to_return(rr[2])

How to rewrite last string using enumerator or something like tap to use all array of rr?

Answer 1

As described in the README, you simply pass the multiple responses to the to_return method as arguments. Basically you want something like:

stub_request(:get, "www.google.de").to_return(rr[0], rr[1], rr[2])

But listing the array values like that is a bit clunky (and won't work with a variable number of responses), so you should instead use Ruby's splat operator:

responses = Dir[File.expand_path("../../markups/*.txt", __FILE__)].map{|f| File.read(f)}
stub_request(:get, "www.google.de").to_return(*responses)

Answer 2

finaly i did it like this

stub = stub_request(:get, "www.google.de")
rr.each { |rf| stub.tap { |s| s.to_return(File.new(rf)) } }
