# Fitting Sponsored by FunBox [![Gem Version](https://badge.fury.io/rb/fitting.svg)](https://badge.fury.io/rb/fitting) [![Build Status](https://travis-ci.org/funbox/fitting.svg?branch=master)](https://travis-ci.org/funbox/fitting) This gem will help you implement your API in strict accordance to the documentation in [API Blueprint](https://apiblueprint.org/) format. To do this, when you run your RSpec tests on controllers, it automatically searches for the corresponding json-schemas in the documentation and then validates responses with them. ## Installation Add this line to your application's Gemfile: ```ruby gem 'fitting' ``` And then execute: $ bundle Or install it yourself as: $ gem install fitting ## Usage In your `.fitting.yml`: ```yaml apib_path: /path/to/doc.apib ``` In your `spec_helper.rb`: ```ruby require 'fitting' Fitting.statistics ``` or ```ruby require 'fitting' responses = Fitting::Storage::Responses.new RSpec.configure do |config| config.after(:each, type: :controller) do responses.add(response) end config.after(:suite) do responses.statistics.save end end ``` ## Example output After running tests you will get statistics in the file `fitting/stats`: ``` Fully conforming requests: DELETE /api/v1/book ✔ 200 ✔ 201 ✔ 404 DELETE /api/v1/book/{id} ✔ 200 ✔ 201 ✔ 404 GET /api/v1/book/{id}/seller ✔ 200 ✔ 201 ✔ 404 Partially conforming requests: GET /api/v1/book ✖ 200 ✔ 404 POST /api/v1/book ✖ 200 ✔ 201 ✔ 404 GET /api/v1/book/{id} ✖ 200 ✔ 404 ✔ 200 PATCH /api/v1/book/{id} ✖ 200 ✔ 201 ✔ 404 Non-conforming requests: GET /api/v1/seller ✖ 200 ✖ 201 ✖ 404 GET /api/v1/buyer ✖ 200 ✖ 404 API requests with fully implemented responses: 3 (33.33% of 9). API requests with partially implemented responses: 4 (44.44% of 9). API requests with no implemented responses: 2 (22.22% of 9). API responses conforming to the blueprint: 16 (64.00% of 25). API responses with validation errors or untested: 9 (36.00% of 25). ``` Also you will get not covered responses in the file `fitting/not_covered`. ## Matchers If you want to know why you get crosses instead of checkmarks you can use matchers for RSpec. ```ruby config.include Fitting::Matchers, type: :controller ``` ### match_schema Makes a simple validation against JSON Schema. ```ruby expect(response).to match_schema ``` ### strictly_match_schema Makes a strict validation against JSON Schema. All properties are condisidered to have `"required": true` and all objects `"additionalProperties": false`. ```ruby expect(response).to strictly_match_schema ``` ## Config You can specify the settings either in a yaml file `.fitting.yml` or in config. If your project uses several prefixes, for each one you need to create a separate yaml file in the folder `fitting` (`fitting/*.yml`). ### apib_path Path to API Blueprint documentation. There must be an installed [drafter](https://github.com/apiaryio/drafter) to parse it. ### drafter_yaml_path Path to API Blueprint documentation pre-parsed with `drafter` and saved to a YAML file. ### strict Default `false`. If `true` then all properties are condisidered to have `"required": true` and all objects `"additionalProperties": false`. ### prefix Prefix of API requests. Example: `'/api'`. Validation will not be performed if the request path does not start with a prefix. ### white_list Default: all paths. This is an array of paths that are mandatory for implementation. This list does not affect the work of the matcher. This list is only for the report in the console. ```yaml white_list: /users: - DELETE - POST /users/{id}: - GET - PATCH /users/{id}/employees: - GET /sessions: [] ``` Empty array `[]` means all methods. ### resource_white_list Default: all resources. This is an array of resources that are mandatory for implementation. This list does not affect the work of the matcher. This list is only for the report in the console. ```yaml resource_white_list: /users: - DELETE /users/{id} - POST /users - GET /users/{id} - PATCH /users/{id} /users/{id}/employees: - GET /users/{id}/employees /sessions: [] ``` Empty array `[]` means all methods. ### include_resources Default: all resources if `include_resources` and `include_actions` is not used. This is an array of resources that are mandatory for implementation. This list does not affect the work of the matcher. This list is only for the report in the console. ```yaml include_resources: - /sessions ``` ### include_actions Default: all paths if `include_resources` and `include_actions` is not used. This is an array of paths that are mandatory for implementation. This list does not affect the work of the matcher. This list is only for the report in the console. ```yaml include_actions: - DELETE /users/{id} - POST /users - GET /users/{id} - PATCH /users/{id} - GET /users/{id}/employees ``` ### ignore_list You can use ignore list for omit checks with matchers. ```yaml ignore_list: - %r{/api/v1/users/[1-9].} - %r{/api/v1/comments} ``` It's work only for match_schema (NOT FOR strictly_match_schema) ## Contributing Bug reports and pull requests are welcome on GitHub at https://github.com/funbox/fitting.
