module Browser
# When testing (using rspec), this module provides some helper methods to
# try and make testing a little easier.
#
# ## Usage
#
# Simply require this file somewher (usualy in `spec_helper.rb`):
#
# require 'application'
# require 'opal-rspec'
# require 'opal/jquery/rspec'
#
# Once required, the module is registered with `rspec` for all example
# groups.
#
# ## Adding html to DOM
#
# It is often convenient to have some `HTML` code ready in the dom for
# testing. This helper method adds the given html string. More so, the html
# is then removed at the end of each test. This is cruicial as it ensures
# that the specified html code is inserted before each test, therefore
# ensuring that html code changed by a test will not affect any other tests
# in the same scope.
#
# describe "Check DOM code" do
# html '<div id="foo"></div>'
#
# it "foo should exist" do
# expect(Document['#foo']).to_not be_empty
# end
# end
#
module RSpecHelpers
# Add some html code to the body tag ready for testing. This will
# be added before each test, then removed after each test. It is
# convenient for adding html setup quickly. The code is wrapped
# inside a div, which is directly inside the body element.
#
# describe "DOM feature" do
# html <<-HTML
# <div id="foo"></div>
# HTML
#
# it "foo should exist" do
# Document["#foo"]
# end
# end
#
# @param [String] html_string html content to add
def html(html_string='')
html = %Q{<div id="opal-jquery-test-div">#{html_string}</div>}

@_spec_html = Element.parse(html)
@_spec_html.append_to_body
