Instance Method Details

#attach_file(field_locator, path, content_type = nil) ⇒ Object

Verifies that an input file field exists on the current page and sets its value to the given file, so that the file will be uploaded along with the form. An optional content_type may be given.

Example:

attaches_file "Resume", "/path/to/the/resume.txt"
attaches_file "Photo", "/path/to/the/image.png", "image/png"

Example:

check 'Remember Me'



72
73
74
 
# File 'lib/webrat/core/scope.rb', line 72

def check(field_locator)
  locate_field(field_locator, CheckboxField).check
end

#choose(field_locator) ⇒ Object

Verifies that an input radio button exists on the current page and marks it as checked, so that the value will be submitted with the form.

Example:

choose 'First Option'



94
95
96
 
# File 'lib/webrat/core/scope.rb', line 94

def choose(field_locator)
  locate_field(field_locator, RadioField).choose
end

#click_area(area_name) ⇒ Object

Issues a request for the URL pointed to by an area tag on the current page, follows any redirects, and verifies the final page load was successful.

The area used is the first area whose title or id contains the given area_name (case is ignored).

Example:

click_area 'Australia'



229
230
231
 
# File 'lib/webrat/core/scope.rb', line 229

def click_area(area_name)
  find_area(area_name).click
end

#click_button(value = nil) ⇒ Object

Verifies that a submit button exists for the form, then submits the form, follows any redirects, and verifies the final page was successful.

Example:

click_button "Login"
click_button

The URL and HTTP method for the form submission are automatically read from the action and method attributes of the <form> element.



274
275
276
 
# File 'lib/webrat/core/scope.rb', line 274

def click_button(value = nil)
  find_button(value).click
end

#click_link(text_or_title_or_id, options = {}) ⇒ Object

Issues a request for the URL pointed to by a link on the current page, follows any redirects, and verifies the final page load was successful.

click_link has very basic support for detecting Rails-generated JavaScript onclick handlers for PUT, POST and DELETE links, as well as CSRF authenticity tokens if they are present.

Javascript imitation can be disabled by passing the option :javascript => false

Passing a :method in the options hash overrides the HTTP method used for making the link request

It will try to find links by (in order of precedence):

innerHTML, with simple &nbsp; handling
title
id

innerHTML and title are matchable by text subtring or Regexp id is matchable by full text equality or Regexp

Example:

click_link "Sign up"
click_link "Sign up", :javascript => false
click_link "Sign up", :method => :put

# File 'lib/webrat/core/scope.rb', line 259

def click_link(text_or_title_or_id, options = {})
  find_link(text_or_title_or_id).click(options)
end

    @dom = scoped_dom
  else
    @dom = page_dom
  end
  
  return @dom
end

#fill_in(field_locator, options = {}) ⇒ Object

Verifies an input field or textarea exists on the current page, and stores a value for it which will be sent when the form is submitted.

Examples:

fill_in "Email", :with => "[email protected]"
fill_in "user[email]", :with => "[email protected]"

The field value is required, and must be specified in options[:with]. field can be either the value of a name attribute (i.e. user[email]) or the text inside a <label> element that points at the <input> field.

def fill_in(field_locator, options = {})
  field = locate_field(field_locator, TextField, TextareaField, PasswordField)
  field.raise_error_if_disabled
  field.set(options[:with])
end

#select(option_text, options = {}) ⇒ Object

Verifies that a an option element exists on the current page with the specified text. You can optionally restrict the search to a specific select list by assigning options[:from] the value of the select list’s name or a label. Stores the option’s value to be sent when the form is submitted.

Examples:

select "January"
select "February", :from => "event_month"
select "February", :from => "Event Month"

# File 'lib/webrat/core/scope.rb', line 109

def select(option_text, options = {})
  select_option(option_text, options[:from]).choose
end

#select_date(date_to_select, options = {}) ⇒ Object

Verifies that date elements (year, month, day) exist on the current page with the specified values. You can optionally restrict the search to a specific date’s elements by assigning options[:from] the value of the date’s label. Selects all the date elements with date provided. The date provided may be a string or a Date/Time object.

Rail’s convention is used for detecting the date elements. All elements are assumed to have a shared prefix. You may also specify the prefix by assigning options[:id_prefix].

Examples:

select_date "January 23, 2004"
select_date "April 26, 1982", :from => "Birthday"
select_date Date.parse("December 25, 2000"), :from => "Event"
select_date "April 26, 1982", :id_prefix => 'birthday'

  id_prefix = locate_id_prefix(options) do
    year_field = FieldByIdLocator.new(@session, dom, /(.*?)_#{DATE_TIME_SUFFIXES[:year]}$/).locate
    raise NotFoundError.new("No date fields were found") unless year_field && year_field.id =~ /(.*?)_1i/
    $1
  end
    
  select date.year, :from => "#{id_prefix}_#{DATE_TIME_SUFFIXES[:year]}"
  select date.strftime('%B'), :from => "#{id_prefix}_#{DATE_TIME_SUFFIXES[:month]}"
  select date.day, :from => "#{id_prefix}_#{DATE_TIME_SUFFIXES[:day]}"
end

#select_datetime(time_to_select, options = {}) ⇒ Object

Verifies and selects all the date and time elements on the current page. See #select_time and #select_date for more details and available options.

Examples:

select_datetime "January 23, 2004 10:30AM"
select_datetime "April 26, 1982 7:00PM", :from => "Birthday"
select_datetime Time.parse("December 25, 2000 15:30"), :from => "Event"
select_datetime "April 26, 1982 5:50PM", :id_prefix => 'birthday'

def select_datetime(time_to_select, options ={})
  time = time_to_select.is_a?(Time) ? time_to_select : Time.parse(time_to_select) 
  
  options[:id_prefix] ||= (options[:from] ? FieldByIdLocator.new(@session, dom, options[:from]).locate : nil)
  
  select_date time, options
  select_time time, options
end

#select_time(time_to_select, options = {}) ⇒ Object

Verifies that time elements (hour, minute) exist on the current page with the specified values. You can optionally restrict the search to a specific time’s elements by assigning options[:from] the value of the time’s label. Selects all the time elements with date provided. The time provided may be a string or a Time object.

Rail’s convention is used for detecting the time elements. All elements are assumed to have a shared prefix. You may specify the prefix by assigning options[:id_prefix].

Note: Just like Rails’ time_select helper this assumes the form is using 24 hour select boxes, and not 12 hours with AM/PM.

Examples:

select_time "9:30"
select_date "3:30PM", :from => "Party Time"
select_date Time.parse("10:00PM"), :from => "Event"
select_date "10:30AM", :id_prefix => 'meeting'

  id_prefix = locate_id_prefix(options) do
    hour_field = FieldByIdLocator.new(@session, dom, /(.*?)_#{DATE_TIME_SUFFIXES[:hour]}$/).locate
    raise NotFoundError.new("No time fields were found") unless hour_field && hour_field.id =~ /(.*?)_4i/
    $1
  end
    
  select time.hour.to_s.rjust(2,'0'), :from => "#{id_prefix}_#{DATE_TIME_SUFFIXES[:hour]}"
  select time.min.to_s.rjust(2,'0'), :from => "#{id_prefix}_#{DATE_TIME_SUFFIXES[:minute]}"
end

#set_hidden_field(field_locator, options = {}) ⇒ Object

Verifies that a hidden field exists on the current page and sets the value to that given by the :to option.

Example:

set_hidden_field 'user_id', :to => 1



62
63
64
65
 
# File 'lib/webrat/core/scope.rb', line 62

def set_hidden_field(field_locator, options = {})
  field = locate_field(field_locator, HiddenField)
  field.set(options[:to])
end

#submit_form(id) ⇒ Object

Submit the form with the given id.

Note that click_button is usually preferrable for simulating form submissions, as you may specify part of the button text rather than the form id.

Example:

submit_form 'login'



288
289
290
 
# File 'lib/webrat/core/scope.rb', line 288

def submit_form(id)
  FormLocator.new(@session, dom, id).locate.submit
end

#uncheck(field_locator) ⇒ Object

Verifies that an input checkbox exists on the current page and marks it as unchecked, so that the value will not be submitted with the form.

Example:

uncheck 'Remember Me'



83
84
85
 
# File 'lib/webrat/core/scope.rb', line 83

def uncheck(field_locator)
  locate_field(field_locator, CheckboxField).uncheck
end
