黄瓜+测试JS警报 [英] Cucumber + testing JS alert

问题描述

我试图用Cucumber on Rails测试一个JS确认对话框。我有一个window.onbeforeunload事件处理程序，如果你尝试离开页面，但我不知道如何测试，任何人都有一个想法，如何这样做，将提示您一个确认对话框。

I'm trying to test a JS confirmation dialog with Cucumber on Rails. I have a window.onbeforeunload event handler that will prompt you with a confirmation dialog if you try to navigate away from the page but I have no idea how to test it, anyone have an idea on how this can be done?

推荐答案

有各种功能的硒可以用来捕获警报/确认。
它们不能直接用于webrat selenium实现，但是当使用webrat的 config.mode =：selenium 时，它们可以使用如下：

There are various functions of selenium you can use to capture alerts/confirms. They are not directly available with the webrat selenium implementation, but when using webrat's config.mode = :selenium they can be used as follows:

Then /^I should see a JS alert$/ do
    selenium.is_alert_present.should be_true
end

# or

Then /^I should see a "Are you sure?" JS confirm dialog$/ do
    selenium.get_alert.should eql("Are you sure?")
end

# you can also click the OK/Cancel buttons on confirm boxes with

selenium.chooseOkOnNextConfirmation();
#and
selenium.chooseCancelOnNextConfirmation();

可能没有最好的测试，但是给你一个想法。
内部selenium覆盖JS的alert（）和confirm（）函数，所以它可以捕获这些信息。

There are probably not the greatest tests, but gives you an idea. Internally selenium overrides the alert() and confirm() functions of JS so it can captures this information.
