= Schnauzer 

- It's a real Safari browser in ruby.
- You can provide your own url request/response handling.
- It's fast.


== > Load a page that has some javascript

	browser = Schnauzer.new
    browser.load_html(%{ 
      <html>
        <body>
        	hello <div id="the_spot"></div>
        	
        	<script type="text/javascript">
	          	document.getElementById('the_spot').innerHTML='world'
        	</script>
        </body>
      </html>
    })
    
    browser.js("document.body.innerHTML") \
      .should include(%{hello <div id="the_spot">world</div>})


== > Provide your own url handling.  Load other resources like js and css files (schnauzer is a real browser, so this just works).
	
	browser = Schnauzer.new do |request, response|
      html =
        if request.fullpath == "/main/page"
          %{<html>
              <link rel="stylesheet" type="text/css" href="/some.css"/>
            

              <body>
              	<i>hello #{request.fullpath}</i>
              	<div id="spot"></div>
              </body>
            
              <script type="text/javascript" language="JavaScript" src="/some.js"></script>
            </html>}
        elsif request.fullpath == "/some.css"
          %{
            body {
              margin: 23px;
            }
          }
        elsif request.fullpath == "/some.js"
          %{
            document.getElementById("spot").innerHTML = "john jay"
          }
        end
      response.write(html)
    end
    
    browser.load_url("local://host/main/page")
    
    browser.js("document.body.innerHTML").should include("<i>hello /main/page</i>")
    browser.js("document.body.innerHTML").should include("<div id=\"spot\">john jay</div>")
    browser.js("window.getComputedStyle(document.body, null).marginLeft").should == "23px"


== > Ajax

      Sinatra.new do
        set :static, true
        set :public, "spec/myapp/public"
        
        get '/foo/hi' do
          "hi I'm a web app"
        end

        get '/echo/:to_echo' do
          "#{params[:to_echo]}, echoed back"
        end


        get '/ajax_page' do
          (<<-HTML)
            <html>

                        {method: 'get',
                         onComplete: function(result){document.getElementById("message").innerHTML = result.responseText},
                         onFailure: function(){document.getElementById("message").innerHTML = "failed"}}
                    )
                  }
