# Cucumber Automated Testing

See our [Cucumber example repository](https://github.com/testingbot/ruby-cucumber-example).

To get started, please make sure you have installed the necessary gems:

    source 'https://rubygems.org'
    gem 'cucumber'
    gem 'selenium-webdriver'
    gem 'rspec'
    gem 'parallel'
    gem 'testingbot'

## Example

Next, we'll create a `features` and a `steps` file. Combined, they're your test.

### Example feature

    Feature: Google can search
    
    Background:
      Given I am on Google
    
    Scenario: Search for a term
      When I fill in "q" found by "name" with "TestingBot"
      And I submit
      Then I should see title "TestingBot - Google Search"

### Example steps

    Given /^I am on (.+)$/ do |url|
      @browser.navigate.to "https://www.google.com"
    end
    
    When /^I fill in "([^"]*)" found by "([^"]*)" with "([^"]*)"$/ do |value, type, keys|
      @element = @browser.find_element(type, value)
      @element.send_keys keys
    end
    
    When /^I submit$/ do
      @element.submit
    end
    
    Then /^I should see title "([^"]*)"$/ do |title|
      raise "Fail" if @browser.title != title
    end

### Example env.rb

    require 'selenium-webdriver'
    require 'testingbot'
    
    Before do
      options = Selenium::WebDriver::Options.send(ENV['browserName'] || 'chrome')
      options.browser_version = ENV['version'] || 'latest'
      options.platform_name = ENV['platform'] || 'WIN11'
      options.add_option('tb:options', {
        key: ENV['TB_KEY'],
        secret: ENV['TB_SECRET']
      })
    
      url = 'https://hub.testingbot.com/wd/hub'
    
      client = Selenium::WebDriver::Remote::Http::Default.new
      client.open_timeout = 180
      @browser = Selenium::WebDriver.for(:remote, url: url, options: options, http_client: client)
    end
    
    After do |test_case|
      sessionid = @browser.session_id
      jobname = test_case.name
    
      puts "TestingBotSessionId=#{sessionid} job-name=#{jobname}"
    
      @browser.quit
    end

Now we can run the test on TestingBot, to start, please run this command:

    cucumber TB_KEY=api_key TB_SECRET=api_secret platform=WIN11 browserName=chrome

### Configuring capabilities

To run your existing tests on TestingBot, your tests will need to be configured to use the TestingBot remote machines. If the test was running on your local machine or network, you can simply change your existing test like this:

**Before:**

    driver = Selenium::WebDriver.for :chrome

**After:**

    driver = Selenium::WebDriver.for(:remote,
      url: 'https://hub.testingbot.com/wd/hub',
      options: options)

## Specify Browsers & Devices

To let TestingBot know on which browser/platform/device you want to run your test on, you need to specify the browsername, version, OS and other optional options in the capabilities field.

    options = Selenium::WebDriver::Options.chrome
    options.browser_version = 'latest'
    options.platform_name = 'WIN11'
    options.add_option('tb:options', {
      key: 'api_key',
      secret: 'api_secret'
    })
    
    driver = Selenium::WebDriver.for(:remote,
      url: 'https://hub.testingbot.com/wd/hub',
      options: options)

To see how to do this, please select a combination of browser, version and platform in the drop-down menus below.

  ![OS selected](https://testingbot.com/assets/environments/svg/windows11-0e1b28bc0fdd5034d3e4d3dc8d346c500a8c6522facf4b45d0da56537c1f1c6d.svg) Windows 11 › ![Browser Selected](https://testingbot.com/assets/environments/svg/chrome-c4081ff447d2d898d4afcb8f074a907c960e6f007716c1a1d119eee6803c4042.svg) Chrome 139

Please wait while we load the available browsers and platforms.

    

## Testing Internal Websites

We've built [TestingBot Tunnel](https://testingbot.com/support/tunnel), to provide you with a secure way to run tests against your staged/internal webapps.  
Please see our [TestingBot Tunnel documentation](https://testingbot.com/support/tunnel) for more information about this easy to use tunneling solution.

The example below shows how to easily run a Cucumber test with our Tunnel:

1. [Download our tunnel](https://testingbot.com/support/tunnel) and start the tunnel:

    java -jar testingbot-tunnel.jar key secret

2. Adjust your test: instead of pointing to `'hub.testingbot.com/wd/hub'` like the example above - change it to point to your tunnel's IP address.   
 Assuming you run the tunnel on the same machine you run your tests, change to `'localhost:4445/wd/hub'`. localhost is the machine running the tunnel, 4445 is the default port of the tunnel.

This way your test will go securely through the tunnel to TestingBot and back:

### Example env.rb

    require 'selenium-webdriver'
    
    options = Selenium::WebDriver::Options.send(ENV['SELENIUM_BROWSER'] || 'chrome')
    options.browser_version = ENV['SELENIUM_VERSION'] || 'latest'
    options.platform_name = ENV['SELENIUM_PLATFORM'] || 'WIN11'
    options.add_option('tb:options', {
      name: 'My first Test',
      key: ENV['TB_KEY'],
      secret: ENV['TB_SECRET']
    })
    
    url = 'http://localhost:4445/wd/hub'
    browser = Selenium::WebDriver.for(:remote, url: url, options: options)
    
    Before do |scenario|
      @browser = browser
    end
    
    at_exit do
      browser.quit
    end

## Run tests in Parallel

Parallel Testing means running the same test, or multiple tests, simultaneously. This greatly reduces your total testing time.

You can run the same tests on all different browser configurations or run different tests all on the same browser configuration.   
 TestingBot has a large grid of machines and browsers, which means you can use our service to do efficient parallel testing. It is one of the key features we provide to greatly cut down on your total testing time.

To start running tests in parallel, first we'll define a `browsers.json` file which contains all the browser combinations:

    [{
      "browserName": "firefox",
      "browserVersion": "latest",
      "platformName": "SONOMA"
    },
    {
      "browserName": "chrome",
      "browserVersion": "latest",
      "platformName": "WIN11"
    }]

Now, we'll create a single test ( **features** and **steps** file) which we'll use to run on the browser combinations we defined above.

    Feature: Google can search
    
    Background:
      Given I am on Google
    
    Scenario: Search for a term
      When I fill in "q" found by "name" with "TestingBot"
      And I submit
      Then I should see title "TestingBot - Google Search"

    Given /^I am on (.+)$/ do |url|
      @browser.navigate.to "https://www.google.com"
    end
    
    When /^I fill in "([^"]*)" found by "([^"]*)" with "([^"]*)"$/ do |value, type, keys|
      @element = @browser.find_element(type, value)
      @element.send_keys keys
    end
    
    When /^I submit$/ do
      @element.submit
    end
    
    Then /^I should see title "([^"]*)"$/ do |title|
      raise "Fail" if @browser.title != title
    end

Now we need to create a Ruby script that will run the test above, and use the environment variables to determine browser/OS combination.

    require 'selenium-webdriver'
    
    options = Selenium::WebDriver::Options.send(ENV['SELENIUM_BROWSER'])
    options.browser_version = ENV['SELENIUM_VERSION']
    options.platform_name = ENV['SELENIUM_PLATFORM']
    options.add_option('tb:options', {
      key: ENV['TB_KEY'],
      secret: ENV['TB_SECRET'],
      build: ENV['TB_AUTOMATE_BUILD']
    })
    
    url = 'https://hub.testingbot.com/wd/hub'
    browser = Selenium::WebDriver.for(:remote, url: url, options: options)
    
    Before do |scenario|
      @browser = browser
    end
    
    at_exit do
      browser.quit
    end

Finally, we create a `Rakefile` which handles the running of the tests in parallel.

    require 'rubygems'
    require 'cucumber'
    require 'cucumber/rake/task'
    require 'parallel'
    require 'json'
    
    @browsers = JSON.load(open('browsers.json'))
    @parallel_limit = ENV["nodes"] || 1
    @parallel_limit = @parallel_limit.to_i
    
    task :cucumber do
      Parallel.each(@browsers, :in_processes => @parallel_limit) do |browser|
        begin
          puts "Running with: #{browser.inspect}"
          ENV['SELENIUM_BROWSER'] = browser['browserName']
          ENV['SELENIUM_VERSION'] = browser['browserVersion']
          ENV['SELENIUM_PLATFORM'] = browser['platformName']
    
          Rake::Task[:run_features].execute()
        rescue StandardError => e
          puts "Error while running task: #{e.message}"
        end
      end
    end
    
    Cucumber::Rake::Task.new(:run_features)
    task :default => [:cucumber]

To run your tests in parallel, run this command:

    rake TB_KEY=api_key TB_SECRET=api_secret nodes=3

### Queuing

Every plan we provide comes with a limit of parallel tests.   
 If you exceed the number of parallel tests assigned to your account, TestingBot will queue the additional tests (for up to 6 minutes) and run the tests as soon as slots become available.

## Mark tests as passed/failed

As TestingBot has no way to determine whether your test passed or failed (it is determined by your business logic), we offer a way to send the test status back to TestingBot. This is useful if you want to see if a test succeeded or failed from the TestingBot member area.

You can use our [Ruby API client](https://github.com/testingbot/testingbot_ruby) to report back test results.

    api = TestingBot::Api.new("key", "secret")
    api.update_test(driver.session_id, { name: "new_name", success: true })
