selenium和ajax的测试问题

Hi,all
I am having doubts in selenium and ajax.
比如：我选择省份，需要等待一点时间才会出现省份下面的市，我才能选择县市，县市是通过选择省份之后触发ajax异步加载的，所以需要等待一点时间，我试着用wait_for_page_to_load()等待，会抛出Time out异常，后来又发现了wait_for_condition(),我就试着用了：

ruby 代码

require "functional_test_case"
class FeedbackTest < FunctionalTestCase
  def test_view_feedback
    login_sh5
    @selenium.click "link=客户反馈信息列表"
    wait_default
    @selenium.type "customer_name", "常相聚"
    @selenium.select "province", "label=上海"
    @selenium.wait_for_condition("var allText=@selenium.get_body_text(); var expected_text='上海市'; allText.indexOf(expected_text)==1;",30000)
    @selenium.select "city", "label=上海市"
    @selenium.select "customer_type", "label=酒店"
    @selenium.select "time_period", "label=本月"
    @selenium.click "//input[@type='image']"
    wait_default
    @selenium.is_text_present("反馈信息内容")
  end
end

结果：Exception: 对象不支持此属性或方法
我觉得是@selenium.wait_for_condition("var allText=@selenium.get_body_text(); var expected_text='上海市'; allText.indexOf(expected_text)==1;",30000)这里不能识别@selenium，但是我看到指南上都是这样用的，难道我错了？

因为大量应用了ajax效果，所以不解决此问题很多测试都无法进行

Thanks in advance

gigix 写道

wait_for_text_present

wait_for_text_present在selenium RC里面没有，它在Selenium on Rails里面

但是我没用Selenium on Rails

Selenium on Rails是不是已经包含selenium ruby？

但是貌似语法格式跟selenium RC很不一样

wait_for_text_present

I can't seem to use Selenium Core to upload a file; when I try to type in the file upload text field, nothing happens!

    Unfortunately, this is yet another JavaScript security restriction; JS is not allowed to modify the value of <input type="file"> form fields. You can work around this by running your tests under Selenium IDE or under Selenium RC running in the experimental "*chrome" mode for Firefox, but at present there is no way to do this on any other browser. This is filed as bug SEL-63, but there may be no way to fix it in Selenium Core.

用了变态的方式解决了

<%= javascript_include_tag :defaults %>

这是导入需要的所有js文件，但是selenium-serve不能加载到
加上http://localhost:3000/，也就是sever地址

<script src="http://localhost:3000/javascripts/prototype.js" type="text/javascript"></script>

这样selenium-server就可以把js文件loaded上了

知道了，可以这样用：<br/>
<div class='code_title'>ruby 代码</div>
<div class='dp-highlighter'>
<div class='bar'> </div>
<ol class='dp-rb' start='1'>
    <li class='alt'><span><span class='variable'>@selenium</span><span>.wait_for_condition(</span><span class='string'>"var allText=selenium.page().bodyText(); var expected_text='上海市'; allText.indexOf(expected_text)&gt;=0;"</span><span>,30000)    </span></span></li>
</ol>
</div>
<br/>
但是selenium-server不能执行rails的remote_function生成的ajax:<span class='attribute-value'> new Ajax.Request</span> ()也即Prototype.js Ajax object而<br/>
导致Exception: Timed out<br/>
<br/>
我还注意到了一个问题，selenium-server跑测试的时候没有加载图片和css样式。<br/>
所以，可能也加载不到javascript文件，包括Prototype.js。因而导致无法执行ajax<br/>
