Python+selenium自动化之29----EC模块之element_located_selection_state_to_be

上一篇介绍selenium中一个模块expected_conditions判断文本是否存在的方法text_to_be_present_in_element。如果有多个选择框需要验证是否被勾选或取消勾选，就需要用到本篇文章介绍的方法element_located_selection_state_to_be。

实例还是结合腾讯企业邮箱的使用。

源码element_located_selection_state_to_be

class element_located_selection_state_to_be(object):

    """ An expectation to locate an element and check if the selection state

    specified is in that state.

    locator is a tuple of (by, path)

    is_selected is a boolean

    """

    def __init__(self, locator, is_selected):

        self.locator = locator

        self.is_selected = is_selected



    def __call__(self, driver):

        try:

            element = _find_element(driver, self.locator)

            return element.is_selected() == self.is_selected

        except StaleElementReferenceException:

            return False

locator：定位器

is_selected：选择状态，bool值，传入一个期望是否被选中，如果期望值与实际状态一致则返回True，不一致则返回False。

判断选中状态

首先登陆邮箱，要用自己的邮箱哦；

选择账户密码登陆；

点击首页的【设置】，进入到设置页，默认为常规设置页

判定文字大小的选择状态是否一致

可以结合测试场景，判定是否被选中，进行选择或取消操作，以及判定操作后的状态。
