Question

我正在尝试自动化从电子商务应用程序中的产品页面进行的购买。用户点击“立即购买”按钮后，会弹出一个登录用户输入用户凭据。用户成功登录后，将显示确认覆盖（并且弹出窗口中的登录将关闭），并带有确认购买选项。但是，webdriver无法识别父浏览器窗口上的会话。

以下是我用来驱动测试的脚本：

require "rubygems"
require "watir-webdriver"
browser = Watir::Browser.start "http://qa02.barnesandnoble.com/w/james-pattersons-witch-   and-wizard-james-patterson/1101936910?ean=2940000962145&itm=1&usri=james+patterson"
browser.button(:caption,'Buy Now').click
sleep 5 #Wait until the Log in Pop comes up
puts browser.windows.size
browser.window(:url,/signin/).use
browser.text_field(:id, "login-email").set "flite-test3@book.com"
browser.text_field(:id, "login-password").set "bookcom"
browser.button(:caption,/Secure Sign In/).click
sleep 8 #Wait until confirm overlay appears
puts browser.windows.size
browser.window(:url,/w/).use
browser.button(:caption,/Confirm/).click




?> browser.button(:caption,/Confirm/).click

Answer 1

我不完全理解browser.window.use的技术细节，因为这是我第一次看到它。但是，我能够通过这样做来运行脚本：

require "rubygems"
require "watir-webdriver"
browser = Watir::Browser.start "http://www.barnesandnoble.com/w/private-games-james-patterson/1104155019?ean=9780316206822&itm=1&usri=james+patterson"
browser.button(:caption,'Buy Now').click
sleep 5 #Wait until the Log in Pop comes up
puts browser.windows.size
browser.window(:url,/signin/).use do
    browser.text_field(:id, "login-email").set "flite-test3@book.com"
    browser.text_field(:id, "login-password").set "bookcom"
    browser.button(:caption,/Secure Sign In/).click
end
sleep 8 #Wait until confirm overlay appears
puts browser.windows.size
browser.window(:url,/w/).use
browser.button(:caption,/Confirm/).click

我所做的改变是：

弹出操作作为一个块传递给browser.window.use
第二个browser.window.use不再需要，所以被删除了
网址已更改为“http://www.barnesandnoble.com/w/private-games-james-patterson/1104155019?ean=9780316206822&itm=1&usri=james+patterson”，因为我无法获取工作的原始网址。我认为这是无关紧要的。

WebDriver :: Error :: UnknownError：Session没有驱动程序。浏览器窗口可能已关闭 - 无法识别确认覆盖
