推荐答案

不幸的是，似乎没有办法在水豚中做到这一点.但是，如果您正在使用Selenium驱动程序(可能还有其他支持JavaScript的驱动程序)运行测试，则可以对其进行破解.在执行将弹出确认对话框的操作之前，请覆盖confirm方法以始终返回true.这样，对话框将永远不会显示，并且您的测试可以继续进行，就像用户按下了确定"按钮一样.如果要模拟反向，只需将其更改为false即可.

Seems like there's no way to do it in Capybara, unfortunately. But if you're running your tests with the Selenium driver (and probably other drivers that support JavaScript), you can hack it. Just before performing the action that would bring up the confirm dialog, override the confirm method to always return true. That way the dialog will never be displayed, and your tests can continue as if the user had pressed the OK button. If you want to simulate the reverse, simply change it to return false.

page.evaluate_script('window.confirm = function() { return true; }')
page.click('Remove')
