Rspec Request Helpers

This gem provides few helpers for request testing

This rules were influenced by real projects experience so In order to use it for your rspec/requests specs you need to follow convention

  RSpec.describe 'Some API' do
    path { '/api/v1/posts' }
    headers do
      {
        'Content-Type' => 'application/json',
        'Accept' => 'application/json',
        'X-App-Token' => user.api_key
      }
    end
    params do
      {
        name: name,
        description: description,
        author_id: author_id
      }
    end
    response do
      { id: 123, name: name, description: description, author: 'Bob Poster' }
    end

    it `creates post` do
      # Ex. do_post_and_assert_201_json_parsed
    end
  end

So what you'll got for that? - Few handy methods for the testing routine

Action	Meaning	RSpec Example
`do_get`, `do_post`, `do_put`, `do_delete`, `do_patch`	Sends apropriate request to endpoint with valid params and headers	`get(path, params, headers)`
`assert_201_json`, `assert_404_xml`, `assert_422_json` etc	Assert response status code and mime type (Dynamicly generated based on config )	`expect(response).to have_http_status(status)` `expect(response.content_type).to eq mime_type`
`assert_200_json_raw`, `assert_201_json_hash`, `assert_201_json_object`	Same as above plus check against raw, hash or object presentation of response	`expect(response_body).to eq(expected_response)`
`do_post_and_assert_201_json_parsed`	Shorthand for asserting content type, HTTP status code and if parsed body of the response is equal to	`expect(response_hash).to eq(expected_response)`

Installation

Add this line to your application's Gemfile:

gem 'rspec_request_helpers'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rspec_request_helpers

In project directory run

$ rails g rspec_request_helpers:install

Configuration

Include helpers into RSpec

# spec/rails_helper.rb

RSpec.configure do |config|
  config.include RspecRequestHelpers

  # This will tell RSpec to collect all failures in test example
  config.define_derived_metadata do |meta|
    meta[:aggregate_failures] = true if meta[:type] == :request
  end
end

Create file config/initializers/rspec_request_helpers.rb

RspecRequestHelpers.configure do |config|
  # Supporded content types
  config.content_types = { json: 'application/json' }

  # Supported status codes
  config.status_codes  = [404, 401, 422, 200, 201]
end

Usage

Generate new rspec file for API endpoint

$ rails g rspec:endpoint <action name>

Example:

$ rails g rspec:endpoint api/v1/users/show
