itesttool

itesttool is Web API end-to-end test tool in RSpec.

describe 'send GET request' do
  _given {
    headers 'referer' => 'http://local.example.com'
  }
  _when { get 'http://localhost:4567/index', as_json }
  _then {
    res.code.should eq '200'
    res.body.should eq_schema_of 'json_schema/hello.json'
    res['$.members..name'].should eq ['Ichiro', 'Jiro', 'Saburo']
  }
end

Installation

Add this line to your application's Gemfile

gem 'itesttool'

And then execute

$ bundle install --path vendor/bundle

Usage

Require itesttool

require 'itesttool'

GET request

• _given is setup phase. _given is alias of before in RSpec.
• _when is execution phase. it send HTTP request to server.
• _then is assertion phase. in _thenblock, HTTP response is set res. res is instance of Net::HTTPResponse.

describe 'send GET request' do
  _given {
    headers 'referer' => 'http://local.example.com'
  }
  _when { get 'http://localhost:4567/index' }
  _then {
    res.code.should eq '200'
  }
end

assert HTTP response

assert status code:

res.code.should eq '200'

assert response body:

res.body.should eq 'Hello world!'

If respons body is the JSON, XML, HTML, you can assert an element using JSONPath, XPath, CSS Selectors.
About JSONPath and XPath, please refer to the site: http://goessner.net/articles/JsonPath/

For assert to the array, itesttool defines custom matchers.

• all
• be_one_and
• be_sorted

[2, 3].should all be > 1  # same next code: [2, 3].each do |x| x.should be > 1 end

[2].should be_one_and be > 1     # success
[2, 3].should be_one_and be > 1  # failure

[1, 2, 3].should be_sorted :asc   # success
[1, 2, 3].should be_sorted :desc  # failure
[3, 2, 1].should be_sorted :desc  # success

JSON

with JSONPath:

res['$.team'].should eq ['ABC']
res['$.members..name'].should eq ['Ichiro', 'Jiro', 'Saburo']
res['$.members..age'].should include 32
res['$.members[::]'].should have(3).items
res['$.members[::]'].should have_at_most(3).items
res['$.members[::]'].should have_at_least(1).items
res['$.members..name'].should all be_kind_of String
res['$.members..age'].should all be_kind_of Integer
res['$.members..age'].should all be > 11
res['$.members..age'].should all be >= 12
res['$.members..age'].should all be < 33
res['$.members..age'].should all be <= 32
res['$.members..age'].should be_sorted :desc

with select helper method:

res.select('$.members..age') do |ages|
  ages.should all be_kind_of Integer
  ages.should all be > 11
  ages.should all be >= 12
  ages.should all be < 33
  ages.should all be <= 32
  ages.should be_sorted :desc
end

you can assert with the JSON Schema.

res.body.should eq_schema_of 'json_schema/hello.json'

json_schema/hello.js is JSON schema sample.

{
  "type": "object",
  "properties": {
    "team": {"type": "string", "required": true},
    "members": {
      "type": "array",
      "items": {
        "type": "object",
        "properties": {
          "name": {"type": "string", "required": true},
          "age":  {"type": "integer", "required": true}
        }
      }
    }
  }
}

XML

with XPath:

res['/root/team/text()'].should eq ['ABC']
res['/root/members//name/text()'].should eq ['Ichiro', 'Jiro', 'Saburo']
res['/root/members//age/text()'].should include '32'
res['/root/members/*'].should have(3).items
res['/root/members/*'].should have_at_most(3).items
res['/root/members/*'].should have_at_least(1).items
res['/root/members//age/text()'].should all be > "11"
res.select('/root/members//age/text()') do |ages|
  ages.should all be >= "10"
  ages.should all be < "33"
  ages.should all be <= "32"
  ages.should be_sorted :desc
end
res['/root/members/member/@order'].should be_sorted :asc

HTML

with CSS Selector:

res['title'].should eq ['Page Title!']
res['h1#team'].should eq ['ABC']
res['.member dd.name'].should eq ['Ichiro', 'Jiro', 'Saburo']
res['.member dd.age'].should include '32'
res['.member'].should have(3).items
res['.member'].should have_at_most(3).items
res['.member'].should have_at_least(1).items
res['.member dd.age'].should all be > "11"
res.select('.member dd.age') do |ages|
  ages.should all be >= 10
  ages.should all be < 33
  ages.should all be <= 32
  ages.should be_sorted :desc
end

query parameter

_when { get 'http://localhost:4567/index?night=true', as_text }
_then {
  res.code.should eq '200'
}

with query helper function:

_when {
  get 'http://localhost:4567/index',
      as_text,
      query('night' => 'true',
            'times' => 3)
}
_then {
  res.code.should eq '200'
}

HTTP request header

_given {
  headers 'referer' => 'http://local.example.com',
          'user_agent' => 'itesttool'
}
_when { get 'http://localhost:4567/index.html', as_html }
_then {
  res.code.should eq '200'
}

POST request

_when {
  post 'http://localhost:4567/login',
}

application/x-www-form-urlencoded

use body_as_form:

_when {
  post 'http://localhost:4567/login',
       body_as_form('nickname' => 'admin',
                    'password' => 'pass'),
       res_is_json
}
_then {
  res.code.should eq '200'
  res['$.nickname'].should eq ['admin']
}

application/json

use body_as_json:

_when {
  post 'http://localhost:4567/echo',
       body_as_json('name' => 'Shiro',
                    'age' => 2),
       res_is_json
}
_then {
  res.code.should eq '200'
  res.body.should eq '{"name":"Shiro","age":2}'
}

use string:

_when {
  post 'http://localhost:4567/echo',
       body('{"name":"Shiro","age":2}'),
       res_is_json
}
_then {
  res.code.should eq '200'
  res.body.should eq '{"name":"Shiro","age":2}'
}
