seleniumwrapper 0.4.1

selenium webdriver wrapper to make manipulation easier.

About this module

selenium webdriver wrapper to make manipulation easier.

Features

• Support remote webdriver.

• Easy to type aliases. (find_element_by_xpath => xpath, etc.)

• Wrapped WebdriverWait( … ).until( … ) pattern.

• Polling at the time of clicking or selecting.

• Wrapping chaining.

How to install

Requires python2.6 or later (exclude python3.x). You need pip or distribute or setuptools:

$ pip install seleniumwrapper

or use easy_install:

$ easy_install seleniumwrapper

also you need selenium:

$ pip install selenium

Example to use

create function helps you to init webdriver and wrap it easily:

>>> import seleniumwrapper as selwrap
>>> br = selwrap.create("chrome")

connect function helps you to use remote webdriver and wrap it:

>>> br = connect("android", "http://localhost:9999", {"acceptSslCerts": True})

SeleniumWrapper delegate to its wrapped webdriver:

>>> br.get("http://www.example.com")
<seleniumwrapper.wrapper.SeleniumWrapper object at 0x...>
>>> br.xpath("//div[@class='main'])
<seleniumwrapper.wrapper.SeleniumWrapper object at 0x...>

Setting eager=True to invoke find_elements:

>>> br.xpath("//a", eager=True)
<seleniumwrapper.wrapper.SeleniumContainerWrapper object at 0x...>

SeleniumContainerWrapper also delegate to its wrapped container:

>>> links = [i.get_attribute("href") for i in br.xpath("//a", eager=True)]

Each contents in SeleniumContainerWrapper also SeleniumWrapper:

>>> tds = [tr.xpath("//td", eager=True) for tr in br.xpath("//tr", eager=True)]

Basic API

• seleniumwrapper.create(drivername)

  Create webdriver instance and wrap it with SeleniumWrapper.

SeleniumWrapper

• unwrap

  Retrieves WebDriver or WebElement from wrapped object:

  >>> isinstance(br.unwrap, WebElement)
  True

• parent

  find_element_by_xpath(“./parent::node()”):

  >>> price = br.by_tag("th", "Price").parent.by_tag("td").text

• to_select

  Convert wrapped WebElement to raw Select object:

  >>> br.by_id('select_button').to_select.select_by_visible_text("hoge")

  select method returns the same as below:

  >>> br.select(id = 'select_button).select_by_visible_text("hoge")

• alert

  Returns Alert(switch_to_alert()) object:

  >>> br.alert.accept()

• current_url

  Returns current_url after loading page body:

  >>> br.current_url

• timeout

  Accessor for _timeout property.

  >>> br.timeout
  5
  >>> br.timeout = 10
  >>> br.timeout
  10
  

• attr(name)

  Shortcut to get_attribute:

  >>> br.attr('href')

• click(timeout=3, presleep=0, postsleep=0)

  Continue to polling until timeout or element is displayed and clickable:

  >>> br.button("Send").click()

• scroll_to(x, y)

  equivalent to javascript’s scrollTo:

  >>> br.scrollTo(0, 100)

• scroll_by(x, y)

  equivalent to javascript’s scrollBy:

  >>> br.scrollBy(10, 10)

• scroll_into_view(jq_identifier, align_with_top=True)

  find elements by jq_identifier and retrieve its first element and invoke scrollIntoView to it:

  >>> var element = $('#hoge');
  >>> element && element.scrollIntoView(true)

  second argument is passed as javascript’s boolean to scrollIntoView:

  >>> br.scrollIntoView('#hoge', False)

• waitfor(type, target, eager=False, timeout=3)

  See source:

  >>> br.waitfor("xpath", "//input[@type='submit']")

• xpath(target, eager=False, timeout=3)

  find_element_by_xpath(target, timeout):

  >>> buttons = br.xpath("//input[@type='submit' or @type='button']", eager=True)

• css(target, eager=False, timeout=3)

  find_element_by_css_selector(target, timeout):

  >>> [li.text for li in br.css("ul li")]

• by_tag(self, tag, eager=False, timeout=3, **attributes)

  Returns specified tagged element with specified attributes optionally.:

  >>> br.by_tag("link", rel="stylesheet")

• by_text(text, tag=’*’, partial=False, eager=False, timeout=3)

  similar to find_element_by_link_text or find_element_by_partial_link_text, but this method can be applicable to any tag:

  >>> br.by_text("Go back to Top Page", "a")

• by_class(target, eager=False, timeout=3)

  find_element_by_class_name(target, timeout):

  >>> br.by_class("colored")

• by_id(target, eager=False, timeout=3)

  find_element_by_id(target, timeout):

  >>> br.by_id("main_contents")

• by_name(target, eager=False, timeout=3)

  find_element_by_name(target, timeout):

  >>> br.by_name("page_password")

• by_linktxt(target, eager=False, timeout=3, partial=False)

  find_element_by_link_text(target, timeout). if partial=True, then find_element_by_partial_link_text:

  >>> br.by_linktxt("Go back to", partial=True)

• href(partialurl=None, eager=False, timeout=3):

  find_element_by_xpath(“//a”, timeout). if partialurl was given, search ‘a’ tag which href contains partialurl:

  >>> phplinks = br.href(".php", eager=True)

• img(alt=None, ext=None, eager=False, timeout=3)

  find_elements_by_xpath(“//img”, timeout):

  >>> br.img(alt="I am sorry", ext="sorry.gif")

• button(value, eager=False, timeout=3)

  find_element_by_xpath(“//input[@type=’submit’ or @type=’button’ and @value=’{}’]”.format(value), timeout):

  >>> br.button("Send this form").click()

• checkbox(self, eager=False, timeout=3, **attributes)

  Returns ‘input’ element type=’checkbox’:

  >>> br.checkbox(name='checked_value', id='hoge')

• radio(self, eager=False, timeout=3, **attributes)

  Retuns ‘input’ element type=’radio’.:

  >>> br.radio(name='hoge', id='fuga').click()

• select(self, eager=False, timeout=3, **attributes)

  Returns Select(self.by_tag(“select”, eager, timeout, **attributes) or their wrapped SeleniumContainerWrapper:

  >>> br.select(name="hoge").select_by_index(1)
  >>> [select.is_multiple for select in br.select(eager=True, name="hoge")]

SeleniumContainerWrapper

• size

  Returns length of wrapped iterable:

  >>> br.img(eager=True).size

• sample(size)

  Returns random.sample(self._iterable, size):

  >>> br.img(eager=True).sample(10)

• choice()

  Returns random.choice(self._iterable):

  >>> br.img(eager=True).choice()
