appium获取Toast内容的方法

做自动化测试的时候，可能需要根据弹出的Toast提示来做下一步判断。这里记录一下获取Toast内容的方法，同时巩固一下显示等待的方法之一WebDriverWait。

from selenium.webdriver.support import expected_conditions as ec

def find_toast(self, driver, message, timeout=10, poll=0.01):
    try:
        message = '//*[@text=\'{}\']'.format(message) #Toast内容
        element = WebDriverWait(driver, timeout,poll).until(ec.presence_of_element_located((By.XPATH, message)))
        return True
    except Exception as e:
        print(("Get Toast Error : ", e))
        return False

presence_of_element_located可以替换为

• title_is
• title_contains
• presence_of_element_located
• visibility_of_element_located   # 和 presence_of_element_located 的作用几乎一样
• visibility_of
• presence_of_all_elements_located
• text_to_be_present_in_element
• text_to_be_present_in_element_value
• frame_to_be_available_and_switch_to_it
• invisibility_of_element_located
• element_to_be_clickable - it is Displayed and Enabled.
• staleness_of
• element_to_be_selected
• element_located_to_be_selected
• element_selection_state_to_be
• element_located_selection_state_to_be
• alert_is_present

By.XPATH中的XPATH可替换为'CLASS_NAME', 'CSS_SELECTOR', 'ID', 'LINK_TEXT', 'NAME', 'PARTIAL_LINK_TEXT', 'TAG_NAME'
