我无法切换到 AndroidDriver 内的 iframe。详情如下。我已经尝试使用 firefox 使用常规 webdriver，并且我能够很好地切换。

代码：

require "selenium-webdriver"
require "selenium/client"

include Selenium::WebDriver::DriverExtensions::HasTouchScreen

caps = Selenium::WebDriver::Remote::Capabilities.android
client = Selenium::WebDriver::Remote::Http::Default.new
client.timeout = 480
driver = Selenium::WebDriver.for(
  :remote,
  :url => "http://localhost:8080/wd/hub",
  :http_client => client,
  :desired_capabilities => caps)

driver.navigate.to "some page with iframe"

driver.switch_to.frame "engagement-iframe"

堆栈跟踪：

我在测试中遇到了同样的问题，我猜这种行为会在 ChromeDriver 上重现。

我的解决方法（一个丑陋的解决方法）是将 iframe 视为一个独立的窗口。

很高兴听到您对此 WebDriver 错误的解决方案
