Minitest Automated Testing

Minitest is a very fast unit testing framework which supports TDD, BDD, mocking and benchmarking.

To begin, please make sure you have Minitest installed on your system:

gem install minitest

Example code

require 'minitest/autorun'
require 'selenium-webdriver'

class GoogleTest < Minitest::Test
  def setup
    options = Selenium::WebDriver::Chrome::Options.new
    options.browser_version = 'latest'
    options.platform_name = 'WIN10'
    options.add_option('tb:options', {
      'key' => 'API_KEY',
      'secret' => 'API_SECRET',
      'name' => 'Minitest Example'
    })

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

  def test_google_search
    @driver.navigate.to 'https://www.google.com'
    element = @driver.find_element(:name, 'q')
    element.send_keys 'TestingBot'
    element.submit
    assert_includes @driver.title, 'TestingBot'
  end

  def teardown
    @driver.quit
  end
end

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.

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.

Testing Internal Websites

We've built TestingBot Tunnel, to provide you with a secure way to run tests against your staged/internal webapps.
Please see our TestingBot Tunnel documentation for more information about this easy to use tunneling solution.

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

1. Download our 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:

require 'minitest/autorun'
require 'selenium-webdriver'

class GoogleTest < Minitest::Test
  def setup
    options = Selenium::WebDriver::Chrome::Options.new
    options.browser_version = 'latest'
    options.platform_name = 'WIN10'
    options.add_option('tb:options', {
      'key' => 'API_KEY',
      'secret' => 'API_SECRET',
      'name' => 'Minitest Tunnel Example'
    })

    @driver = Selenium::WebDriver.for(:remote,
      url: 'http://localhost:4445/wd/hub',
      options: options
    )
  end

  def test_google_search
    @driver.navigate.to 'https://www.google.com'
    element = @driver.find_element(:name, 'q')
    element.send_keys 'TestingBot'
    element.submit
    assert_includes @driver.title, 'TestingBot'
  end

  def teardown
    @driver.quit
  end
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.

The example below demonstrates how you can easily run tests simultaneously in a variety of browsers.

Create a browsers.json file with the list of browsers you want to use to run tests in parallel:

[
    {
      "browserName": "firefox",
      "browserVersion": "latest",
      "platformName": "WIN10"
    },
    {
      "browserName": "safari",
      "browserVersion": "18",
      "platformName": "SEQUOIA"
    },
    {
      "browserName": "chrome",
      "browserVersion": "latest",
      "platformName": "WIN11"
    }
  ]

Now we need to create the test and use environment variables which we will pass to the test script.

require 'minitest/autorun'
require 'selenium-webdriver'

class GoogleTest < Minitest::Test
  def setup
    # Dynamically select browser options based on environment
    options_class = case ENV['TB_BROWSERNAME']
      when 'firefox' then Selenium::WebDriver::Firefox::Options
      when 'safari' then Selenium::WebDriver::Safari::Options
      else Selenium::WebDriver::Chrome::Options
    end

    options = options_class.new
    options.browser_version = ENV['TB_VERSION']
    options.platform_name = ENV['TB_PLATFORM']
    options.add_option('tb:options', {
      'key' => 'API_KEY',
      'secret' => 'API_SECRET',
      'name' => 'Parallel Test'
    })

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

  def test_google_search
    @driver.navigate.to 'https://www.google.com'
    element = @driver.find_element(:name, 'q')
    element.send_keys 'TestingBot'
    element.submit
    assert_includes @driver.title, 'TestingBot'
  end

  def teardown
    @driver.quit
  end
end

Now we need to create a Rakefile which will start the tests in parallel.

require 'rake/testtask'
require 'parallel'
require 'json'

@browsers = JSON.load(File.open('browsers.json'))
@test_folder = 'test/*_test.rb'
@parallel_limit = (ENV['nodes'] || 1).to_i

task :minitest do
  current_browser = ''
  begin
    Parallel.map(@browsers, in_threads: @parallel_limit) do |browser|
      current_browser = browser
      puts "Running Browser: #{browser.inspect}"
      ENV['TB_BROWSERNAME'] = browser['browserName']
      ENV['TB_VERSION'] = browser['browserVersion']
      ENV['TB_PLATFORM'] = browser['platformName']
      Dir.glob(@test_folder).each do |test_file|
        IO.popen("ruby #{test_file}") do |io|
          io.each { |line| puts line }
        end
      end
    end
  rescue SystemExit, Interrupt
    puts 'User stopped script!'
    puts "Failed to run tests for #{current_browser.inspect}"
  end
end

task default: [:minitest]

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 to report back test results.

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