I was writing a feature in which I had webrat push a button. However,
there are many buttons on this page with the same text. I wanted to
specify which one would be push in as close a way I could to the way a
person would describe which one he was pushing. Here is what I ended up
with:
#custom_webrate_steps.rb
require 'rexml/document'
include REXML
When /^I push "(.*)" near "(.*)"$/ do |button, text|
#The dom element that contains the text must have an id
rexml_doc = Document.new(response.body)
regexp = /#{Regexp.escape(text)}/
nodes = find_nodes_with_regexp(rexml_doc, regexp)
dom_id = nodes.first.attributes['id']
within '#' + dom_id do |scope|
scope.clicks_button(button)
end
end
def find_nodes_with_regexp(node, regexp)
result = []
result << node if node.methods.include?('text') && node.text =~ regexp
node.each {|n| result += find_nodes_with_regexp(n, regexp)} if
node.methods.include?('each')
result
end
Any ideas for making this *nicer*?
