jQuery Chosen Testing with Capybara

test_multi_select.rb

=begin
Notes
=====
Labels: On the label you should put a "for" attribute if you're not using something like simple_form
This helps capybara to find your field
e.g. <label for="my_field_id">Some label</label>
=end

field = "Label on my field"
value = "existing option in list"

# Find the field
field = find_field(field_name)

# Open the Chosen drop down
page.execute_script(%Q!$("##{field[:id]}_chzn").mousedown()!)
# Simulate text being typed
typed_text = ""
value.chars.each do |char|
  typed_text += char
  # Put a value in the search field
  page.execute_script(%Q!$("##{field[:id]}_chzn input").val("#{typed_text}")!)
  # Fire the search via a keyup
  page.execute_script(%Q!$("##{field[:id]}_chzn input").keyup()!)
end

# Do the selection via firing a keyup on the Enter key when you have the exact text for the option
page.execute_script(%Q!$("##{field[:id]}_chzn input").trigger(jQuery.Event("keyup", { keyCode: $.ui.keyCode.ENTER }))!)

# OR

# Do the selection via firing a mouse up on the option when you have partial text for the option
page.execute_script(%Q!$("##{field[:id]}_chzn .chzn-results li:contains('#{value}')").mouseup()!)

Very nice, thanks ;)

This works really nicely for me, thanks. I'm using it with Poltergeist.

Thanks, works really well. Note that with Capybara 2+ you need to pass 'visible: false' to find_field. So the above would read:

find_field(field_name, visible: false)

I found this thread helpful for getting me started on how to tackle this problem some 5 years later.

Here is what my code looks like:

 # Find the field
  id = find_field(label, visible: false)[:id]

  # Open the Chosen drop down
  page.execute_script(%Q!$("##{id}_chosen").mousedown()!)

  # Put a value in the search field
  page.execute_script(%Q!$("##{id}_chosen input").val("#{option}")!)
  # Fire the search via a keyup
  page.execute_script(%Q!$("##{id}_chosen input").keyup()!)

  # # Do the selection via firing a mouse up on the option
  page.execute_script(%Q!$("##{id}_chosen .chosen-results li:contains('#{option}')").mouseup()!)
