To see how these have been implement: calabash_steps.rb

Custom Steps:

Macro Steps:

The simplest way of writing custom steps is to combine one or more existing steps. You do this using the macro function.

Then /^the First page should display the correct components$/ do macro 'I should see "First View"' macro 'I see 2 input field' macro 'I should see a "Name" input field' macro 'I should see "switch"' macro 'I should see a "login" button' macro 'I should see an "Alert" button' end

If a step fails then you will get a useful error message

Expected at least 2 text/input fields, found 1 (RuntimeError)

Ruby API:

Things you can do

  • touch
  • retrieve label
  • query
  • check if something exists in the view
  • use the keyboard
  • rotate the device
  • traverse views (using Directions)

Methods:

  • touch()
  • label()
  • query()
  • element_exists()
  • element_does_not_exist()
  • view_with_mark_exists()
  • sleep()
  • wait_for()
  • scroll()
  • scroll_to_row()
  • check_element_exists()
  • keyboard_enter_char()
  • done()
  • rotate()
  • screenshot()

UI Elements:

  • view
  • label
  • textField
  • button

Selectors:

  • index:0
  • marked:’London’
  • placeholder:’username’
  • accessibilityIdentifier:’location_name’
  • accessibilityLabel:’London’
  • isEnabled:1
  • text:’Hello’
  • view:’MyClassName’
  • webView css:’#header’

NSPredicate examples:

  • {text LIKE ‘Hel*’}

Arguments:

  • numberOfRowsInSection:0
  • :up
  • :down
  • :right
  • :left

Directions / Traversal:

  • parent
  • child

Properties:

  • :accessibilityLabel
  • :accessibilityIdentifier
  • :placeholder

query(“button”, :titleLabel, :text) query(“button buttonLabel text:’Foo Bar’)

Examples:

2 ways to check if an element exists with a specific accessibilityIdentifier

element_exists("view marked:'location_name'") element_exists("view accessibilityIdentifier:'location_name'")

2 ways to retrieve the text of a view with a specific accessibilityIdentifier

query("view marked:'location_name'", :text)[0] query("view accessibilityIdentifier:'location_name'", :text)[0]

Ways to output properties in the IRC

classes "view" label "view"

  • In general you use a NSPredicate by writing a filter: {selector OP comp}, where selector is the name of a selector you want to perform on the object and OP and comp are an operation and something to compare with. See also Predicate Programming Guide
