Rails functional test: sending URL query parameters in POST request

Question

I\'m sending a POST request in a Rails functional test like this:

post :create, collection: { name: \'New Collection\' }

collection

Answer 1

This is also a problem when testing POST actions with RSpec (v3.4).

A workaround is to mock the return value of request.GET or request.query_string methods.

it "should recognise a query parameter in post action" do
  allow(subject.request).to receive(:query_string).and_return("api_key=my%20key")  
  @params = {collection: { name: 'New Collection' }}


  expect(subject.request.query_string).to eq "api_key=my%20key"

  post :create, @params
end
