Cucumber::Http

This library provides Cucumber steps to test JSON HTTP API's. The steps are rather verbose (technical) in nature, somewhat contrary to the Cucumber philosophy of high-level, descriptive tests. This is intentional as it allows these steps to be bundled in larger, more high-level tests by non-developers.

Installation

Add this line to your application's Gemfile:

gem 'cucumber-http'

And then execute:

$ bundle

Or install it yourself as:

$ gem install cucumber-http

Examples

Examples for testing the REST API of UiTDatabank:

@api @labels
Feature: Test the UDB3 labels API

  Background:
    Given I am using the UDB3 development environment
     And I am authorized as user "centraal_beheerder"
     And I send "application/json" and accept "application/ld+json"

  @labelcreate
  Scenario: Create label
    When I create a label with a random name of 10 characters
     And I keep the value of the JSON response at "uuid" as "uuid"
     And I send a GET request to "/labels/%{uuid}"
    Then the response status should be "200"
     And the JSON response at "visibility" should be "visible"
     And the JSON response at "privacy" should be "public"

@api @images
Feature: Test the UDB3 image API

  Background:
    Given I am using the UDB3 development environment
     And I am authorized as user "centraal_beheerder"
     And I accept "application/json"

   @imagecreate
   Scenario: Create image
     Given I set the form data properties to:
        | description     | logo |
        | copyrightHolder | me   |
        | language        | nl   |
     When I upload "file" from path "images/UDB.jpg" to "/images/"
     Then the response status should be "201"

Benchmarking

Given /^I am benchmarking$/

Then 'the elapsed time should be less than {float} second(s)'

HTTP

Given /^I set headers?:$/

Given /^I send "(.*?)"$/

Given /^I accept "(.*?)"$/

Given /^I send and accept "(.*?)"$/

Given /^I send "(.*?)" and accept "(.*?)"$/

Given /^I send "(.*?)" and accept JSON$/

Given /^I send and accept JSON$/

Given 'I set the form data properties to:'

Given /^I set the JSON request payload to:$/

Given /^I set the JSON request payload from "(.*?)"$/

When /^I send a (GET|POST|PATCH|PUT|DELETE) request to "([^"]*)"(?: with parameters?:)?$/

When 'I upload {string} from path {string} to {string}"'

Then 'the response status should be "{int}"'

Then 'the response status should not be "{int}"'

Then /^the response body should be valid JSON$/

Debugging

Then /^show me the( unparsed)? response$/

Then /^show me the kept values?$/

JSON (through JsonSpec)

These steps are documented in the json_spec README

Making larger, more descriptive tests

The steps in this library are overly technical for use in Cucumber as a communication tool between developers and business people. They are meant to be encapsulated in larger, more general steps through the use of the steps method in Cucumber.

This allows easier reuse of code and the ability for non-developers to write requirements.

Examples for testing the REST API of UiTDatabank:

Creating an organizer with a random name:

When 'I create an organizer with a random name of {integer} character(s)' do |characters|
  name = Faker::Lorem.characters(characters)
  steps %Q{
    Given I am using the UDB3 development environment
      And I am authorized as user "centraal_beheerder"
      And I send and accept "application/json"
     When I set the JSON request payload to:
       """
       {"mainLanguage":"nl","website":"https://www.#{name}.be","name":"#{name}","contact":[]}
       """
      And I send a POST request to "/organizers/"
  }
end

Creating a role with a random name:

When 'I create a role with a random name of {integer} character(s)' do |characters|
  name = Faker::Lorem.characters(characters)
  steps %Q{
    Given I am using the UDB3 development environment
      And I am authorized as user "centraal_beheerder"
      And I send and accept "application/json"
     When I set the JSON request payload to:
       """
       { "name": "#{name}" }
       """
      And I send a POST request to "/roles/"
  }
end

Development
