在 selenium 中加载包含有用测试功能的外部 js 文件 [英] Load an external js file containing useful test functions in selenium

问题描述

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.
