Query param matchers for rspec/rails

url_matchers.rb

# Match query params on some url somewhere in a text [actually a mail.body, hence the to_s]
# Not tested in production
RSpec::Matchers.define :include_query_params do |expected|
  match do |actual|
    query_finder = /http\S+\?(\S+)["\s'>]/
    queries = query_finder.match actual.to_s
    queries.captures.any? do |q|
      q_hash = Rack::Utils.parse_nested_query(q).symbolize_keys
      q_hash.merge(expected) == q_hash
    end
  end
end

# Match a single query parameter somewhere in the a url [very dumb]
RSpec::Matchers.define :query_param do |expected|
  expected = expected.to_query
  match do |actual|
    actual.include?(expected)
  end
