加载包含硒有用的测试功能的外部JS文件 [英] Load an external js file containing useful test functions in selenium

问题描述

在硒的runScript命令真的很有用，而且我用它来总值的表，然后存储这样的值

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>

在理想情况下，我想能够指向外部的js文件，而不是在命令作为一个字符串的JavaScript，这样我就可以在某些测试功能加载和使用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

因此​​，我们不得不

<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>

和外部脚本看起来像这样

And the external script would look like this

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);
}

关于它的思考插件增加了一个loadScript动作用于检查外部js文件，然后通过文件内容的runScript会做这项工作。但我并不想另起炉灶，我从来没有在以前建造的插头。

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

的的runScript 命令只是增加了一个＆LT; SCRIPT＆GT; 包含脚本到DOM，让浏览器中运行它的元素。你可以做自己相同的，而不是在行脚本，使用 SRC = 属性告诉浏览器加载哪些文件。您可能需要加载从Web服务器上的文件，因为一些浏览器将不允许从网上下载页面访问文件：网​​址

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.
