Watir with webdriver, proxy, Firefox - firefox

Question

I am able to use watir-webdriver with IE, but I would prefer to use Firefox.
Problem: I need a proxy.
By googling around, I found some code snippets, but I am not able to put all them together.
This is what I produced up to now, please let me know what am I missing:
require 'watir-webdriver'
FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("network.proxy.http", "proxy.myplace.com");
profile.setPreference("network.proxy.http_port", 8080);
WebDriver driver = new FirefoxDriver(profile);
browser = Watir::Browser.new :firefox
browser.goto( "http://www.google.com/" )
I get this error message:
I:/watir/webdriver/webdrivertest.rb:3: syntax error, unexpected tCONSTANT, expec
ting keyword_do or '{' or '('
FirefoxProfile profile = new FirefoxProfile();
Also, I don't know how to use the variable called 'driver'

Answer 1

Call the underlying Selenium WebDriver.
I've used this technique to set a path to Firefox 3.6 so I can test with both Firefox 4 and 3.6:
Selenium::WebDriver::Firefox.path = ENV['FIREWATIRPATH']
browser = Watir::Browser.new :firefox
So to do what you're trying to do:
profile = Selenium::WebDriver::Firefox::Profile.new
proxy = Selenium::WebDriver::Proxy.new(:http => "http://proxy.org:8080")
profile.proxy = proxy
# You have to do a little more to use the specific profile
driver = Selenium::WebDriver.for :firefox, :profile => profile
browser = Watir::Browser.new(driver)
Look at: Selenium Ruby Bindings and Webdriver FAQ for more info.
What problem are you having with the Proxy line?
You could try this:
profile = Selenium::WebDriver::Firefox::Profile.new
profile["network.proxy.type"] = 1
profile["network.proxy.http"] = "proxy.myplace.com"
profile["network.proxy.http_port"] = 8080
The idea is to see what your settings are in about:config and duplicating them in code.

Answer 2

profile = Selenium::WebDriver::Firefox::Profile.new
profile.proxy = Selenium::WebDriver::Proxy.new :http => '12.12.12.12:8888', :ssl => '15.15.15.15:443'
browser = Watir::Browser.new :firefox, :profile => profile

Answer 3

The base problem in your original question is right in the error message
webdrivertest.rb:3: syntax error, unexpected tCONSTANT, expecting keyword_do or '{' or '('
The ruby interpreter is seeing something on the third line of your script that looks like a constant, in a place it's expecting something else.
I suspect it's the start of the line where ruby expects a variable name, and you have a classname. Ruby expects variables named starting with an uppercase to be a constant. which is fine for defining a class, but not creating an instance of one, since the instance won't be a constant.
It also looks like you are trying to do a new invocation using a 'new' keyword ala some other language, instead of using a .new method on whatever object you want to make a new one of, the ruby way.
Compare the code in the answer by Mike where he does
profile = Selenium::WebDriver::Firefox::Profile.new
verses what you were trying to do on line 3
FirefoxProfile profile = new FirefoxProfile();
See how different they are? His is the way to do it.
