Appium_python3 抓取客户端toast

在客户端登录或者退出登录的时候会有吐司提示，因此需要抓取来验证用户登录成功或者注销成功；

在获取toast之前需要添加   desired_caps['automationName'] = 'Uiautomator2' , 否则无法获取到toast

 调用toast方法一：

def is_toast_exist(self,driver, text=None, timeout=8, poll_frequency=0.01):
    try:
        toast_loc = ("xpath", ".//*[contains(@text,'%s')]" % text)
        WebDriverWait(driver, timeout, poll_frequency).until(EC.presence_of_element_located(toast_loc))
        return True
    except Exception as e:
        return False

调用toast方法二：

def get_toast_text(self, text, timeout=5, poll_frequency=0.01):
    try:
        toast_element = (By.XPATH, "//*[contains(@text, " + "'" + text + "'" + ")]")
        toast = WebDriverWait(self.driver, timeout, poll_frequency).until(EC.presence_of_element_located(toast_element))
        return toast.text
    except Exception as e:
        raise e
