Topic: RSpec testing module methods


Working on testing a pure-ruby application I have with rspec. I have some methods that are in a module, not a class. When I run my rspec code, it cannot find the methods I test.

# spec/copyprocess/copyprocess_spec.rb

require 'spec_helper'

module CopyProcess
  describe CopyProcess do
    describe "#contains_valid_headers" do
      it "should return false if invalid" do
        CopyProcess::contains_valid_headers('').should == false

The above contains_valid_headers method cannot be found.

I declare it in the following file:

# lib/copyprocess.rb

require 'copyprocess/content_element'
require 'copyprocess/content_row'

module CopyProcess  
  def get_inner_index(value, arr)
    idx = nil
    arr.each_with_index do |e, i|
      if e[0] == value
        idx = i
    return idx
  def includes_inner?(value, arr)
    bool = false
    arr.each { |e| bool = true if e[0] == value  }
    return bool
  # This method confirms the content of the text file has valid HEADER values.
  # @param [String] value - a string containing the contents from the text file
  # @return [Array]
  def contains_valid_headers(value)
    split_value = value.split(/\n/)
    if(split_value[0].index('/*').nil? || split_value[4].index('*/').nil?)
      return false
      start_index = value.index('/*')
      return false if start_index.nil?
      end_index = value.index('*/', start_index+2)
      return false if end_index.nil?
      value = value[start_index+2..end_index-1]
      type_i = value.index('Type:')
      layer_i = value.index('Layer:')
      variation_i = value.index('Variation:')
      return false if type_i.nil? || layer_i.nil? || variation_i.nil?
      # sets the type, layer, variation as an array
      headers = [value[type_i+5..layer_i-1], value[layer_i+6..variation_i-1], value[variation_i+10..value.size]]
      # return it with each value stripped of nextline characters and extra white space
      return headers.collect { |c| c.gsub(/\n|\t/, '').strip }

 # ...
  class CopyFile
  # end of CopyFile class

I have require 'copyprocess'
in the spec_helper file

Any ideas as to why that is? Feel free to view my full code and structure: … perimental

Re: RSpec testing module methods

I think you refer to the method like MyModule::my_method in case it is defined as def self.my_method. In your case I think you probably have to mix your module into test class to test it... Right below the describe do include CopyProcess and refer to methods as they were local...

That did the trick, thanks
