在 selenium 中加载包含有用测试功能的外部 js 文件
selenium 中的 runScript 命令真的很有用，我用它来汇总表中的值，然后像这样存储值
The runScript command in selenium is really useful, and I'm using it to total values in a table and then store the value like this
<tr>
<td>runScript</td>
<td>var cumulative = 0.0; $('table.quote-review-group-component').eq(0).find('tr').each( function( i,el ){var singleStackTotal = $(el).find('td').eq(4).html();if( singleStackTotal ){cumulative += parseFloat( singleStackTotal.substring(1) );} }); cumulative = cumulative.toFixed(2)</td>
<td></td>
</tr>
<tr>
<td>storeEval</td>
<td>selenium.browserbot.getUserWindow().cumulative</td>
<td>cumulative</td>
</tr>
<tr>
<td>echo</td>
<td>${cumulative}</td>
<td></td>
</tr>
<tr>
<td>verifyEquals</td>
<td>£${cumulative}</td>
<td>${total}</td>
</tr>
理想情况下，我希望能够指向外部 js 文件，而不是将命令中的 javascript 作为字符串，这样我就可以加载一些测试函数并使用 storeEval 来获取函数的返回
Ideally I'd like to be able to point to an external js file rather than have the javascript in the command as a string, so that I can load in some test functions and use storeEval to get the return of the function
所以我们有
<tr>
<td>runExternalScript</td>
<td>/path/to/external/extra-tests.js</td>
<td></td>
</tr>
<tr>
<td>storeEval</td>
<td>selenium.browserbot.getUserWindow().getCumulative(0)</td>
<td>cumulative0</td>
</tr>
<tr>
<td>verifyEquals</td>
<td>£${cumulative}</td>
<td>${total}</td>
</tr>
外部脚本看起来像这样
function checkSingleGroupListTotal( index ){
if ( index == "undefined" ){
index = 0;
}
var cumulative = 0.0;
$('table.quote-review-group-component').eq(index).find('tr').each( function( i,el ){
var singleStackTotal = $(el).find('td').eq(4).html();
if( singleStackTotal ){
cumulative += parseFloat( singleStackTotal.substring(1) );
}
});
return cumulative.toFixed(2);
}
考虑一个插件，它添加一个 loadScript 动作来检查外部 js 文件，然后将文件内容传递给 runScript 就可以完成这项工作.但我不想重新发明轮子，而且我之前从未构建过插件.
Thinking about it a plugin which adds a loadScript action which checks for the external js file and then passes the file contents to runScript would do the job. But I don't want to reinvent the wheel, and I've never built a plug in before.
推荐答案
runScript 命令只是将包含脚本的 <SCRIPT> 元素添加到 DOM 并让浏览器运行它.你可以自己做同样的事情，而不是使用内嵌脚本，使用 SRC= 属性来告诉浏览器要加载什么文件.您可能必须从 Web 服务器加载文件，因为某些浏览器不允许从网络加载的页面访问 file: URL.
The runScript command merely adds a <SCRIPT> element containing the script to the DOM and lets the browser run it. You can do the same yourself, and instead of an in-line script, use the SRC= attribute to tell the browser what file to load. You may have to load the file from a web server, because some browsers won't allow page loaded from the net to access a file: URL.
