1.toast获取

def hook_toast_method(self, selector, inner_text=None):
    """
    封装hook wx API接口，获取回调  showToast
    :param selector: 触发元素选择器
    :return: toast
    """
    before = Callback()
    # hook wx API接口，获取回调后执行callback
    self.mini.app.hook_wx_method("showToast", before=before)

    # 点击元素，会触发toast的操作
    self.get_element(selector, inner_text=inner_text).tap()

    before_args = before.get_callback_result(10)
    # 释放hook
    self.mini.app.release_hook_wx_method("showToast")

    toast = before_args['title']
    self.logger(toast)
    return toast

2.模态弹框操作

def show_modal(self, btn_text='确定'):
    """
    模态弹框，属于native控件，无法直接定位操作，需要用到 native方法
    :param btn_text:
    :return:
    """
    self.mini.native.handle_modal(btn_text=btn_text)

3.等待某个元素出现某个属性，比如，等待按钮可以点击

def wait_for_attribute(self, selector, name, value, max_timeout=10):
    """
    等待元素属性出现
    :param selector:
    :param name:
    :param value:
    :param max_timeout:
    :return:
    """
    def page_wait():
        value1 = self.mini.page.get_element(selector).attribute(name)[0]
        return value1 == value

    self.mini.assertTrue(self.mini.page.wait_for(page_wait, max_timeout=max_timeout))
    self.logger(f"等待元素属性 {name}  {value}")
