# Rspec::ApiHelpers

Usefull Rspec helpers for APIs (currently only ActiveModel Serializers are supported)

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'rspec-api_helpers', github: 'kollegorna/rspec-api_helpers'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install rspec-api_helpers

## Usage
This Gem expects you to have set your rspec to use Rake::Test helpers as described
[here](https://gist.github.com/alex-zige/5795358) because it checks `last_response`
attributes.

### Examples

```ruby
it_returns_status(200)
```
It checks if the HTTP response status is 200.

```ruby
it_returns_attributes(resource: 'user', model: '@user', only: [
  :email, :name
])
```
It checks if the HTTP body contains an AMS json that has :email and :name attributes and
compares them with '@user' variable's attributes.

```ruby
it_returns_more_attributes(
  resource: 'user',
  model: 'User.last!',
  only: [:updated_at, :created_at],
  modifier: 'iso8601'
)
```
It checks if the HTTP body contains an AMS json that has :updated_at and :created_at
attributes and compares them with '@user' variable's attributes after it applies modifier.

```ruby
it_returns_resources(root: 'users', number: 5)
```
It checks if the HTTP body contains an AMS json with an array of 'users'.
