## Looking for Project Maintainers
I am looking for project maintainers to help keep airborne up to date and bug-free while avoiding feature creep and maintaining backwards compatibility.
Comment [here](https://github.com/brooklynDev/airborne/issues/134) if you would like to help out.
## Installation
Install Airborne:
```shell
$ gem install airborne
```
Or add it to your Gemfile:
```ruby
gem 'airborne'
```
## Creating Tests
```ruby
require 'airborne'
describe 'sample spec' do
it 'should validate types' do
get 'http://example.com/api/v1/simple_get' #json api that returns { "name" : "John Doe" }
expect_json_types(name: :string)
end
it 'should validate values' do
get 'http://example.com/api/v1/simple_get' #json api that returns { "name" : "John Doe" }
expect_json(name: 'John Doe')
end
end
```
When calling expect_json_types, these are the valid types that can be tested against:
* `:int` or `:integer`
* `:float`
* `:bool` or `:boolean`
* `:string`
* `:date`
* `:object`
* `:null`
* `:array`
* `:array_of_integers` or `:array_of_ints`
* `:array_of_floats`
* `:array_of_strings`
* `:array_of_booleans` or `:array_of_bools`
* `:array_of_objects`
* `:array_of_arrays`
If the properties are optional and may not appear in the response, you can append `_or_null` to the types above.
```ruby
describe 'sample spec' do
it 'should validate types' do
get 'http://example.com/api/v1/simple_get' #json api that returns { "name" : "John Doe" } or { "name" : "John Doe", "age" : 45 }
expect_json_types(name: :string, age: :int_or_null)
end
end
```
Additionally, if an entire object could be null, but you'd still want to test the types if it does exist, you can wrap the expectations in a call to `optional`:
```ruby
it 'should allow optional nested hash' do
get '/simple_path_get' #may or may not return coordinates
expect_json_types('address.coordinates', optional(latitude: :float, longitude: :float))
end
```
Additionally, when calling `expect_json`, you can provide a regex pattern in a call to `regex`:
```ruby
describe 'sample spec' do
it 'should validate types' do
get 'http://example.com/api/v1/simple_get' #json api that returns { "name" : "John Doe" }
expect_json(name: regex("^John"))
end
end
```
When calling `expect_json` or `expect_json_types`, you can optionally provide a block and run your own `rspec` expectations:
```ruby
describe 'sample spec' do
it 'should validate types' do
get 'http://example.com/api/v1/simple_get' #json api that returns { "name" : "John Doe" }
expect_json(name: -> (name){ expect(name.length).to eq(8) })
end
end
```
Calling `expect_json_sizes` actually make use of the above feature and call `expect_json` under the hood:
```ruby
describe 'sample spec' do
it 'should validate types' do
get 'http://example.com/api/v1/simple_get_collection' #json api that returns { "ids" : [1, 2, 3, 4] }
expect_json_sizes(ids: 4)
end
end
```
## Making requests
Airborne uses `rest_client` to make the HTTP request, and supports all HTTP verbs. When creating a test, you can call any of the following methods: `get`, `post`, `put`, `patch`, `delete`, `head`, `options`. This will then give you access the following properties:
* `response` - The HTTP response returned from the request
* `headers` - A symbolized hash of the response headers returned by the request
* `body` - The raw HTTP body returned from the request
* `json_body` - A symbolized hash representation of the JSON returned by the request
For example:
```ruby
it 'should validate types' do
get 'http://example.com/api/v1/simple_get' #json api that returns { "name" : "John Doe" }
name = json_body[:name] #name will equal "John Doe"
body_as_string = body
end
```
When calling any of the methods above, you can pass request headers to be used.
```ruby
get 'http://example.com/api/v1/my_api', { 'x-auth-token' => 'my_token' }
```
For requests that require a body (`post`, `put`, `patch`) you can pass the body as well:
```ruby
post 'http://example.com/api/v1/my_api', { :name => 'John Doe' }, { 'x-auth-token' => 'my_token' }
```
The body may be any JSON-serializable type, as long as you want to post `application/json` content type.
You may set a different content type and post a string body this way:
```ruby
post 'http://example.com/api/v1/my_api', "Hello there!", { content_type: 'text/plain' }
```
For requests that require Query params you can pass a params hash into headers.
```ruby
post 'http://example.com/api/v1/my_api', { }, { 'params' => {'param_key' => 'param_value' } }
```
### (Not) Verifying SSL Certificates
SSL certificate verification is enabled by default (specifically, `OpenSSL::SSL::VERIFY_PEER`).
Carefully consider how you use this. It's not a solution for getting around a failed SSL cert verification; rather, it's intended for testing systems that don't have a legitimate SSL cert, such as a development or test environment.
You can override this behavior per request:
```ruby
verify_ssl = false
post 'http://example.com/api/v1/my_api', "Hello there!", { content_type: 'text/plain' }, verify_ssl
```
or with a global Airborne configuration:
```ruby
Airborne.configure do |config|
config.verify_ssl = false # equivalent to OpenSSL::SSL::VERIFY_NONE
end
```
Note the per-request option always overrides the Airborne configuration:
```ruby
before do
Airborne.configuration.verify_ssl = false
end
it 'will still verify the SSL certificate' do
verify_ssl = true
post 'http://example.com/api/v1/my_api', "Hello there!", { content_type: 'text/plain' }, verify_ssl
end
```
You can use the `verify_ssl` setting to override your global defaults in test blocks like this:
```ruby
describe 'test something', verify_ssl: false do
end
```
OR
```ruby
describe 'test something' do
Airborne.configuration.verify_ssl = false
end
```
This feature currently isn't supported when testing loaded Rack applications (see "Testing Rack Applications" below). If you need to set `verify_ssl: false`, then we recommend starting your Rack app server and sending the `airborne` HTTP requests as you would when testing any other service.
## Testing Rack Applications
If you have an existing Rack application like `sinatra` or `grape` you can run Airborne against your application and test without actually having a server running. To do that, just specify your rack application in your Airborne configuration:
```ruby
Airborne.configure do |config|
config.rack_app = MySinatraApp
end
```
Under the covers, Airborne uses [rack-test](https://github.com/brynary/rack-test) to make the requests.
## Rails Applications
If you're testing an API you've written in Rails, Airborne plays along with `rspec-rails`:
```ruby
require 'rails_helper'
RSpec.describe HomeController, :type => :controller do
describe 'GET index' do
it 'returns correct types' do
get :index, :format => 'json' #if your route responds to both html and json
expect_json_types(foo: :string)
end
end
end
```
## API
* `expect_json_types` - Tests the types of the JSON property values returned
* `expect_json` - Tests the values of the JSON property values returned
* `expect_json_keys` - Tests the existence of the specified keys in the JSON object
* `expect_json_sizes` - Tests the sizes of the JSON property values returned, also test if the values are arrays
* `expect_status` - Tests the HTTP status code returned
* `expect_header` - Tests for a specified header in the response
* `expect_header_contains` - Partial match test on a specified header
## Path Matching
When calling `expect_json_types`, `expect_json`, `expect_json_keys` or `expect_json_sizes` you can optionally specify a path as a first parameter.
For example, if our API returns the following JSON:
```json
{
"name": "Alex",
"address": {
"street": "Area 51",
"city": "Roswell",
"state": "NM",
"coordinates": {
"latitude": 33.3872,
"longitude": 104.5281
}
}
}
```
This test would only test the address object:
```ruby
describe 'path spec' do
it 'should allow simple path and verify only that path' do
get 'http://example.com/api/v1/simple_path_get'
expect_json_types('address', street: :string, city: :string, state: :string, coordinates: :object)
#or this
expect_json_types('address', street: :string, city: :string, state: :string, coordinates: { latitude: :float, longitude: :float })
end
end
```
Or, to test the existence of specific keys:
```ruby
it 'should allow nested paths' do
get 'http://example.com/api/v1/simple_path_get'
expect_json_keys('address', [:street, :city, :state, :coordinates])
end
```
Alternatively, if we only want to test `coordinates` we can dot into just the `coordinates`:
```ruby
it 'should allow nested paths' do
get 'http://example.com/api/v1/simple_path_get'
expect_json('address.coordinates', latitude: 33.3872, longitude: 104.5281)
end
```
When dealing with `arrays`, we can optionally test all (`*`) or a single (`?` - any, `0` - index) element of the array:
Given the following JSON:
```json
{
"cars": [
{
"make": "Tesla",
"model": "Model S"
},
{
"make": "Lamborghini",
"model": "Aventador"
}
]
}
```
We can test against just the first car like this:
```ruby
it 'should index into array and test against specific element' do
get '/array_api'
expect_json('cars.0', make: 'Tesla', model: 'Model S')
end
```
To test the types of all elements in the array:
```ruby
it 'should test all elements of the array' do
get 'http://example.com/api/v1/array_api'
expect_json('cars.?', make: 'Tesla', model: 'Model S') # tests that one car in array matches the tesla
expect_json_types('cars.*', make: :string, model: :string) # tests all cars in array for make and model of type string
end
```
`*` and `?` work for nested arrays as well. Given the following JSON:
```json
{
"cars": [
{
"make": "Tesla",
"model": "Model S",
"owners": [
{
"name": "Bart Simpson"
}
]
},
{
"make": "Lamborghini",
"model": "Aventador",
"owners": [
{
"name": "Peter Griffin"
}
]
}
]
}
```
===
```ruby
it 'should check all nested arrays for specified elements' do
get 'http://example.com/api/v1/array_with_nested'
expect_json_types('cars.*.owners.*', name: :string)
end
```
## Dates
JSON has no support for dates, however airborne gives you the ability to check for dates using the following. For `expect_json_types` you would use it as you would for any of the other types:
```ruby
it 'should verify date type' do
get '/get_date' #api that returns {createdAt: "Mon Oct 20 2014 16:10:42 GMT-0400 (EDT)"}
expect_json_types(createdAt: :date)
end
```
However if you want to check the actual date data with `expect_json`, you need to call the `date` function:
```ruby
it 'should verify correct date value' do
get '/get_date' #api that returns {createdAt: "Mon Oct 20 2014 16:10:42 GMT-0400 (EDT)"}
prev_day = DateTime.new(2014,10,19)
next_day = DateTime.new(2014,10,21)
#within the date callback, you can use regular RSpec expectations that work with dates
expect_json(createdAt: date { |value| expect(value).to be_between(prev_day, next_day) })
end
```
## Configuration
When setting up Airborne, you can call `configure` just like you would with `rspec`:
```ruby
#config is the RSpec configuration and can be used just like it
Airborne.configure do |config|
config.include MyModule
end
```
Additionally, you can specify a `base_url` and default `headers` to be used on every request (unless overridden in the actual request):
```ruby
Airborne.configure do |config|
config.base_url = 'http://example.com/api/v1'
config.headers = { 'x-auth-token' => 'my_token' }
end
describe 'spec' do
it 'now we no longer need the full url' do
get '/simple_get'
expect_json_types(name: :string)
end
end
```
You can also control the strictness of `expect_json` and `expect_json_types` with the global settings `match_expected_default` and `match_actual_default` like this.
```ruby
Airborne.configure do |config|
config.match_expected_default = true
config.match_actual_default = false
end
```
`match_expected_default` requires all the keys in the expected JSON are present in the response.
`match_actual_default` requires that the keys in the response are tested in the expected Hash.
So you can do the following combinations:
`match_expected_default=false`, `match_actual_default=false` - check only intersection
`match_expected_default=false`, `match_actual_default=true` - raise on extra key in response
`match_expected_default=true`, `match_actual_default=false` - raise on missing key in response
`match_expected_default=true`, `match_actual_default=true` - expect exact match
Airborne sets `match_expected_default` to `true` and `match_actual_default` to `false` by default.
You can use the `match_expected` and `match_actual` settings to override your global defaults in test blocks like this.
```ruby
describe 'test something', match_expected: true, match_actual: false do
end
```
OR
```ruby
describe 'test something' do
Airborne.configuration.match_expected = true
Airborne.configuration.match_actual = false
end
```
## Run it from the CLI
```shell
$ cd your/project
$ rspec spec
```
