Example App

You can see a Rails 4 example app with the recorded markdown inside the tests-doc folder

Usage

In your spec_helper.rb RSpec file:

require 'tests_doc'

config.include ::TestsDoc::RecordSpecHelper, type: :request

TestsDoc.configure do |config|
  # The regexes allow you to by pass run time object updated_at and other ids
  # run time object between each execution
  config.changes_whitelist_regex      = /(.*\"((id)|([\w]+((_id)|(_at))))\":.*\n)|(.*_ids":\s\[\s*\w+\s*\])/ # default: ""

  # OR
  config.changes_whitelist_regexes = [
    /\"id\":.*\n/,
    /_id\":.*\n/,
    /_at\":.*\n/,
    /.*_ids":\s\[\s*\w+\s*\]/
  ]

  # Folder location where the tests doc will be stored
  config.root_folder = Rails.root.join("api_interactions")  # default: tests-doc

  # Folder name where the tests doc will be stored
  config.doc_folder  = 'api' # default: api

  # Key separator between the path and the key
  config.key_separator = '@' # default: @

  # Add RSpec line number to the test doc
  config.add_spec_file_number = false # default: true

  # tests-doc file will save the timestamps of the last modification
  config.add_index_timestamps = false # default: true

  # Will output the diff debug of recorded test docs
  config.debug = true # default: false
end

Recording interactions in your tests

In your request spec file simply wrap your request with recording_api_interaction:

recording_api_interaction do
  get users_path
end

You can also set options for the recording:

• The key option allows to record a test doc and append to the file name the key:

recording_api_interaction do |options|
  options.key = 'with-filter'
  get posts_path(published: true)
end

Will generate a markdown file named [email protected].

• The path option allows to specify the path you want, a good reason for that is that you want to extract the id of you ActiveRecord object.

recording_api_interaction do |options|
  options.path = 'users/@id/posts'
  get user_posts_path(User.first)
end

Will generate here a markdown file named posts.md in the users/@id folder.

• the whitelist option allow you to add on the global regex whitelist:

recording_api_interaction do |options|
  options.whitelist = /\"token\":.*\n/
  get users_path(User.first)
end

Generating the Index file

You can generate the index file that list all endpoint using the following rake command.

rake tests_doc:index:build

If you want to only build it if there is a git changes on your file:

rake tests_doc:index:build_if_changed

You could also specify which folder to use for the index file:

rake "tests_doc:index:build_if_changed[api_interactions]"

It's also possible to rewrite the index after the RSpec suite:

config.after :suite do |test|
  # block executed when there is any api interactions were recorded during the RSpec
  TestsDoc.with_api_interaction do
    require 'rake'
    require 'tests_doc/tasks'

    Rake::Task["tests_doc:index:build_if_changed"].invoke(TestsDoc.configuration.root_folder)
  end
end
