python selenium webdriver方法封装（find_element_by）

下面是对find_element_by_就行了封装，封装之后的高级方法就是getElement()

下面是具体的代码：

 def getElement(self, selector):
        """
        to locate element by selector
        :arg
        selector should be passed by an example with "i,xxx"
        "x,//*[@id='langs']/button"
        :returns
        DOM element
        """
        if ',' not in selector:
            return self.driver.find_element_by_id(selector)
        selector_by = selector.split(',')[0]
        selector_value = selector.split(',')[1]

        if selector_by == "i" or selector_by == 'id':
            element = self.driver.find_element_by_id(selector_value)
        elif selector_by == "n" or selector_by == 'name':
            element = self.driver.find_element_by_name(selector_value)
        elif selector_by == "c" or selector_by == 'class_name':
            element = self.driver.find_element_by_class_name(selector_value)
        elif selector_by == "l" or selector_by == 'link_text':
            element = self.driver.find_element_by_link_text(selector_value)
        elif selector_by == "p" or selector_by == 'partial_link_text':
            element = self.driver.find_element_by_partial_link_text(selector_value)
        elif selector_by == "t" or selector_by == 'tag_name':
            element = self.driver.find_element_by_tag_name(selector_value)
        elif selector_by == "x" or selector_by == 'xpath':
            element = self.driver.find_element_by_xpath(selector_value)
        elif selector_by == "s" or selector_by == 'selector_selector':
            element = self.driver.find_element_by_css_selector(selector_value)
        else:
            raise NameError("Please enter a valid type of targeting elements.")

        return element

    def type(self, selector, text):
        """
        Operation input box.

        Usage:
        driver.type("i,el","selenium")
        """
        el = self.getElement(selector)
        el.clear()
        el.send_keys(text)

以上的代码是封装了find_element_by_的几种方法，在具体使用封装过的代码的时候，只需要简单的调用即可。

调用示例

    def login(self, userName, password):
        self.openPage(self.loginPageUrl)
        # self.driver.clearCookies()
        self.driver.implicitlyWait(5)
        self.driver.type("account", userName)
        self.driver.type("password", password)
        self.driver.click("submit")

自动化的测试代码示例

    def test_ranzhi_login(self):
        """
        测试用例：测试然之登录
        :return:
        """
        # 新建然之的页面对象
        loginPage = RanzhiSubLoginPage(self.autoDriver, self.baseUrl)

        # 利用然之的页面对象进行登录
        loginPage.login("admin", "admin")
        sleep(2)
        # 断言 是否登录成功
        self.assertEqual(loginPage.getMainPage(), self.autoDriver.getUrl(), u"登录失败")
