Question

are there any 3rd party libs at all in python that do something on top of webdriver?

I am considering using selenium webdriver in python, but i would really like to use a ui-module based approach. What i mean by that is instead of code that might look like this:

cheese = driver.find_element_by_css_selector("#food span.dairy.aged")
cheese.click()

i want something like (not python!):

   ui.Div(uid: "div1", clocator: [id: "div1"]) {
      Div(uid: "inner-container", clocator: [id: "div2"]) {
        List(uid: "list1", clocator: [tag: "ul"], separator: "li"){
          UrlLink(uid: "{all}", clocator: [:])
        }
      } 
   }
   click 'inner-container'

So I define my UI beforehand, and then write the testcases. If the UI changes, I need to change the UI module definition and not worry about the testcases.

I can hand roll this, but are there any libs for python that do this for me?

There is no existing project that I am aware of that does what you want. One pattern that I’ve been using in my functional tests with Webdriver is to define each logical page as a class. Something like this:

class LoginPage(object):

    def __init__(self, testcase):
        self.tc = testcase

    def login(self, username, password, at_login_page=False):
        if not at_login_page:
            self.tc.browser.get(self.tc.ROOT + '/login')

        self.tc.browser.find_element_by_id('id_username').send_keys(username)
        self.tc.browser.find_element_by_id('id_password').send_keys(password)
        login_button = self.tc.browser.find_element_by_id('login-button').click()

And then use it in in the test like so, where ‘self’ in this case is an instance of unit test :

    login_page = site_pages.LoginPage(self)
    login_page.login(self.username, self.password)

Using this pattern might get you close to what you want to do. The way a page works is logically contained in the class methods, instead of being endlessly repeated through each functional test.
