`console.rb` uses some code from [simple_test.rb](
https://github.com/appium/appium/blob/82995f47408530c80c3376f4e07a1f649d96ba22/sample-code/examples/ruby/simple_test.rb) and is released under the [same license](https://github.com/appium/appium/blob/c58eeb66f2d6fa3b9a89d188a2e657cca7cb300f/LICENSE) as Appium. The [Accessibility Inspector](https://developer.apple.com/library/ios/#documentation/UserExperience/Conceptual/iPhoneAccessibility/Testing_Accessibility/Testing_Accessibility.html) is helpful for discovering button names and textfield values.

#### generic

- `source` Prints a JSON view of the current page.
- `page` Prints the content descriptions and text values on the current page.
- `(Element) find(value)` Returns the first element that contains value.
- `(Element) finds(value)` Returns all elements containing value (iOS only for now).
- `(Element) name(name)` Returns the first element containing name. Android name is the content description.
iOS uses accessibility label with a fallback to text.
- `(Array<Element>) names(name)` Returns all elements containing name.
- `(Element) text(text)` Returns the first element containing text.
- `(Array<Element>) texts(text)` Returns all elements containing text.

e.type
e.tag_name # calls .type (patch.rb)

alert.dismiss

# Secure textfield example.

# Enter password

[routing.js](https://github.com/appium/appium/blob/master/app/routing.js#L69) lists not yet implemented end points.

#### Driver

`start_driver` will restart the driver.

`x` will quit the driver and exit Pry.

`execute_script` calls `$driver.execute_script`

`find_element` calls `$driver.find_element`

`find_elements` calls `$driver.find_elements`

`mobile :swipe, endX: 100, endY: 100, duration: 0.01` calls `$driver.execute_script 'mobile: swipe', endX: 100, endY: 100, duration: 0.01`

`no_wait` will set implicit wait to 0. `$driver.manage.timeouts.implicit_wait = 0`

`set_wait` will set implicit wait to default 30 seconds. `$driver.manage.timeouts.implicit_wait = 30`

`set_wait(timeout_seconds)` will set implicit wait to desired timeout. `$driver.manage.timeouts.implicit_wait = timeout`

.click to tap an element.
.send_keys to type on an element.

#### Raw UIAutomation

`execute_script "au.lookup('button')[0].tap()"` is the same as
`execute_script 'UIATarget.localTarget().frontMostApp().buttons()[0].tap()'`

See [app.js](https://github.com/appium/appium/blob/master/app/uiauto/appium/app.js#L3) for more au methods.
Note that raw UIAutomation commands are not offically supported.

Advanced au.

In this example we lookup two tags, combine the results, wrap with $, and then return the elements.

```ruby
s = %(
var t = au.lookup('textfield');
var s = au.lookup('secure');
var r = $(t.concat(s));
au._returnElems(r);
)

execute_script s
```

#### XPath

See [#194](https://github.com/appium/appium/pull/194/files) for details.

```ruby
find_element  :xpath, 'button'
find_elements :xpath, 'button'

find_element  :xpath, 'button[@name="Sign In"]'
find_elements :xpath, 'button[@name="Sign In"]'

find_element  :xpath, 'button[contains(@name, "Sign In")]'
find_elements :xpath, 'button[contains(@name, "Sign")]'

find_element :xpath, 'textfield[@value="Email"]'
find_element :xpath, 'textfield[contains(@value, "Email")]'

find_element  :xpath, 'text[contains(@name, "Reset")]'
find_elements :xpath, 'text[contains(@name, "agree")]'
```

#### Cucumber Sauce Integration

Reset after each test and when done report the result to Sauce after quiting the driver.

```ruby
require 'rest_client' # https://github.com/archiloque/rest-client
require 'json' # for .to_json

$passed = true

After do |scenario|
  # Reset scenario unless the feature was tagged @keep
  $driver.execute_script 'mobile: reset' unless scenario.feature.source_tag_names.include? '@keep'

  if $passed
    $passed = false if scenario.failed?
  end
end

at_exit do
  # selenium-webdriver (2.32.1) or better can use
  # $driver.session_id
  ID = $driver.send(:bridge).session_id
  driver_quit
  
  if !SAUCE_USERNAME.nil? && !SAUCE_ACCESS_KEY.nil?
    URL = "https://#{SAUCE_USERNAME}:#{SAUCE_ACCESS_KEY}@saucelabs.com/rest/v1/#{SAUCE_USERNAME}/jobs/#{ID}"

    # Keep trying until passed is set correctly. Give up after 30 seconds.
    wait do
      response = RestClient.put URL, { 'passed' => $passed }.to_json, :content_type => :json, :accept => :json
      response = JSON.parse(response)

      # Check that the server responded with the right value.
      response['passed'] == $passed
    end
  end
end
```
