Ruby+Watir经验谈: javascript popup box

作者: lifr 来源: 51testing博客

Watir对Dom Tree有超强的能力，但一旦超出了它的势力范围，比如 javascrīpt popup box，它就无能为力了。

   解决这个问题的思路是启动另外一个进程，利用第三方工具(AutoIt)，来完成对这些对象的操作。

   Watir安装已经自带了AutoIt，但它的辅助方法还不太好。主要是缺少判断是否有box弹出的方法。

   附件里提供有两个scrīpt，一个是作为另外一个进程运行的脚本clickJsDialogButton.rb，它的功能描述如下

    1) 探测pop box
    2) 如果发现了popup box，click "enter" key, or "escape" key.
    "enter" key 和click OK button效果一样
    "escape" key 和click Cancel button效果一样

1 # argument: {ENTER}, or{ESCAPE}
2 # return 0(true) if there is a box pops up, 1(false) if not.
3 require 'watir/WindowHelper'
4
5 AutoItRetTimeout = 0
6 AutoItRetSucceed = 1
7
8 DefaultTimeOut = 30
9
10 IETitle = "Microsoft Internet Explorer"
11 PRESSKEY = ARGV.shift
12
13 autoit = WIN32OLE.new('AutoItX3.Control')
14 foundAndClicked = false
15
16 ret = autoit.WinWait IETitle, "", DefaultTimeOut
17 if ret==AutoItRetSucceed # 0 timeout, 1 succeed
18 autoit.Send PRESSKEY
19 foundAndClicked=true
20 end
21
22
23 ShellExitTrue = 0
24 ShellExitFalse = 1
25
26 exit foundAndClicked ? ShellExitTrue : ShellExitFalse

还有一个是提供操纵popup box的jsDlg.rb

module Everbright
    module Util
    # module JsDialog helps to handle javascrīpt popup box.
    #
    # Javascrīpt popup box is out of the control of Watir::IE,
    # so we cannot detect/click an javascrīpt box by a Watir::IE instance.
    #
    # Basically, methods of JsDlg accept an block by running which there
    # will pops up an javascrīpt dialog box. Then you can click "OK" or "Cancel" button of it.
        #
        # Also you can detect whether or not there will pop up a dialog box by method JsDlg.popAlertbox?.
        # This method is especially useful to test input validation.
    module JsDlg

        # click button of a pop-up js dialog box
        #    button can be
        #        :OK
        #        :CANCEL
        #
        # return thread
        def clickJsDialogButton(button)
        path = File.join(File.dirname(__FILE__), "clickJsDialogButton.rb")

        key = button==:OK ? "{ENTER}" :
            button==:CANCEL ? "{ESCAPE}" : nil
        raise "buton can only be :OK or :CANCEL" if key.nil?

        #puts "cmd = "+"ruby \"#{path}\" \"#{key}\""
        t = Thread.new { system("ruby \"#{path}\" \"#{key}\"") }
        return t
        end

        def toClickAlertOk #:yield:
        clickJsDialogButton(:OK)
        yield
        end

        def toClickConfirmOk #:yield:
        clickJsDialogButton(:OK)
        yield
        end

        def toClickConfirmCancel #:yield:
        clickJsDialogButton(:CANCEL)
        yield
        end

        # Whether running the block leads an alert dialog box pops up?
        # if yes, click "OK" button of the alert dialog box and return true
        # if no, return false
        def popAlertBox?(&block)
        path = File.join(File.dirname(__FILE__), "clickJsDialogButton.rb")

        ret = true
        t = Thread.new { ret = system("ruby \"#{path}\" \"{ENTER}\"") }
        block.call
        t.join
        return ret
        end

        module_function :toClickAlertOk, :toClickConfirmOk, :toClickConfirmCancel
        module_function :popAlertBox?, :clickJsDialogButton
    end
    end
end

   使用JsDlg，操纵popup box就非常简单了，比如删除操作往往都会弹出一个confirm窗口
JsDlg.toClickConfirmOK {
    ie.button(:caption, /delete/).click
}

   在输入了一些非法数据后，测试提交form时有alertbox弹出
assert_true(JsDlg.popAlertBox?{ ie.button(:caption, /Submit/).click })

   注意，这里并没有处理prompt窗口。因为在我的测试中一直也没有用到
