watir webdriver 和 javascript 对话框我有示例并且无法在测试中摆脱该警报。这是 javascript

<script>
alert("hello.\n\nPress OK to go.");
</script>

然后我需要点击它并加载页面

require 'watir-webdriver'
require 'webdriver-user-agent'
b = Watir::Browser.new Webdriver::UserAgent.driver(:browser => :chrome, :agent => phone.to_sym, :orientation => :landscape)
b.goto "file:///test.html"

错误是

/var/lib/gems/1.9.1/gems/selenium-webdriver-2.37.0/lib/selenium/webdriver/remote/response.rb:51:in `assert_ok': unexpected alert open (Selenium::WebDriver::Error::UnhandledAlertError)

    from test.rb:13:in `block in <main>'
    from test.rb:7:in `each'
    from test.rb:7:in `<main>'

和

b.execute_script "window.onbeforeunload = null"

如果 javascript 与 window.onbeforeunload 不同，这可以正常工作

但是这个警报给了我错误，之后的一切都不再起作用了，因为我不能点击那个警报，所以页面加载了。

# don't return anything for alert
browser.execute_script("window.alert = function() {}")

# return some string for prompt to simulate user entering it
browser.execute_script("window.prompt = function() {return 'my name'}")

# return null for prompt to simulate clicking Cancel
browser.execute_script("window.prompt = function() {return null}")

# return true for confirm to simulate clicking OK
browser.execute_script("window.confirm = function() {return true}")

# return false for confirm to simulate clicking Cancel
browser.execute_script("window.confirm = function() {return false}")

# don't return anything for leave page popup
browser.execute_script("window.onbeforeunload = null")

但它不起作用，因为页面没有加载并且警报在之前，我找不到点击它的方法。

这似乎有点hacky，但以下似乎工作。

require 'watir-webdriver'
require 'webdriver-user-agent'

driver = Webdriver::UserAgent.driver(:browser => :chrome, :agent => phone.to_sym, :orientation => :landscape)
b = Watir::Browser.new driver

begin
  b.goto "file:///test.html"
rescue Selenium::WebDriver::Error::UnhandledAlertError
  b.alert.ok
end

# Continue to use the page

基本上，你：

  1. 转到页面
  2. 抢救异常
  3. 在alert中使用watir的alert API点击ok
  4. 继续上路
