#check_region(element, how = nil, what = nil, options = {}) ⇒ Object

Takes a snapshot of the application under test and matches a region of a specific element with the expected region output.

Examples:

Check region by element

check_region(element, tag: 'Check a region by element', match_timeout: 3, stitch_content: false)

Check region by css selector

check_region(:css, '.form-row .input#e_mail', tag: 'Check a region by element', match_timeout: 3,
stitch_content: false)

Parameters:

  • element (Applitools::Selenium::Element) —

    Represents a region to check.

  • how (Symbol) (defaults to: nil) —

    a finder, such :css or :id. Selects a finder will be used to find an element See Selenium::Webdriver::Element#find_element documentation for full list of possible finders.

  • what (String) (defaults to: nil) —

    The value will be passed to a specified finder. If finder is :css it must be a css selector.

  • options (Hash) (defaults to: {})

Options Hash (options):

  • :tag (String) —

    An optional tag to be associated with the snapshot.

  • :match_timeout (Fixnum) —

    The amount of time to retry matching. (Seconds)

  • :stitch_content (Boolean) —

    If set to true, will try to get full content of the element (including hidden content due overflow settings) by scrolling the element, taking and stitching partial screenshots.

#test(options = {}) {|driver| ... } ⇒ Object

Use this method to perform seamless testing with selenium through eyes driver. It yields a block and passes to it an Applitools::Selenium::Driver instance, which wraps standard driver. Using Selenium methods inside the ‘test’ block will send the messages to Selenium after creating the Eyes triggers for them. Options are similar to #open

Examples:

eyes.test(app_name: 'my app', test_name: 'my test') do |driver|
   driver.get "http://www.google.com"
   driver.check_window("initial")
end
