我正在使用python- Appium客户端为我的混合android应用程序，我如何设置超时异常，如NoSuchElement异常等，因为如果我切换到WebView，有异常Appium python客户端不会引发异常，只是无限等待。
Appium日志:

使用selenium的WebDriverWait，你可以等待元素的出现，或者它的可见性，或者它是可点击的。更多信息在这里:硒-等待，直到元素出现，可见和可交互
from appium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
desired_caps = {
"platformName": "Android",
"deviceName": "emulator-5554",
"automationName": "UiAutomator2",

driver = webdriver.Remote('http://localhost:4723/wd/hub', desired_caps)
# after 120 seconds, if the condition isn't validated, a timeout exception will occur
# wait for the element's presence
WebDriverWait(driver, 120).until(EC.presence_of_element_located((By.XPATH, '//android.widget.Button[@resource-id="com.google.android.youtube:id/random_btn"]')))
# wait for the element's visiblity
# WebDriverWait(driver, 120).until(EC.visibility_of_element_located((By.XPATH, '...')))
# wait for the element to be clickable
# WebDriverWait(driver, 120).until(EC.element_to_be_clickable((By.XPATH, '...')))
使用此方法:
self.driver.implicitly_wait(5) # waits 5 seconds
