如何用Selenium IDE 实现简单的循环和条件语句

Selenium是一个很好用的Web界面测试框架。但它的功能也有不足之处，比如： 在Selenium IDE中不支持程序控制语句。下面介绍如何在Selenium IDE中添加程序控制功能。
1） 下载Selenium插件 （sideflow.js）：
如果不想下载，直接把下面的代码保存到本机也可。
2） 简单的应用 if-else function 我们一般会用到gotoIf，gotolabel和label这三个command，在selenium ide里按照command | target | value的顺序举个简单的例子：
举例录制新浪通行证的注册模块：
添加sideflow.js文件的步骤，需要在selenium的options——general中添加sideflow.js文件，添加后重启Selenium IDE。
其中sideflow.js的下载地址：

sideflow.js的代码如下：
var gotoLabels= {};
var whileLabels = {};
// overload the original Selenium reset function
Selenium.prototype.reset = function() {
// reset the labels
this.initialiseLabels();
// proceed with original reset code
this.defaultTimeout = Selenium.DEFAULT_TIMEOUT;
this.browserbot.selectWindow("null");
this.browserbot.resetPopups();
}
Selenium.prototype.initialiseLabels = function()
{
gotoLabels = {};
whileLabels = { ends: {}, whiles: {} };
var command_rows = [];
var numCommands = testCase.commands.length;
for (var i = 0; i <</span> numCommands; ++i) {
var x = testCase.commands[i];
command_rows.push(x);
}
var cycles = [];
var forEachCmds = [];
for( var i = 0; i <</span> command_rows.length; i++ ) {
if (command_rows[i].type == 'command')
switch( command_rows[i].command.toLowerCase() ) {
case "label":
gotoLabels[ command_rows[i].target ] = i;
break;
case "while":
case "endwhile":
cycles.push( [command_rows[i].command.toLowerCase(), i] )
break;
case "foreach":
case "endforeach":
forEachCmds.push( [command_rows[i].command.toLowerCase(), i] )
break;
}
}
var i = 0;
while( cycles.length ) {
if( i >= cycles.length ) {
throw new Error( "non-matching while/endWhile found" );
}
switch( cycles[i][0] ) {
case "while":
if( ( i+1 <</span> cycles.length ) && ( "endwhile" == cycles[i+1][0] )) {
// pair found
whileLabels.ends[ cycles[i+1][1] ] = cycles[i][1];
whileLabels.whiles[ cycles[i][1] ] = cycles[i+1][1];
cycles.splice( i, 2 );
i = 0;
} else ++i;
break;
case "endwhile":
++i;
break;
}
}
}
Selenium.prototype.continueFromRow = function( row_num )
{
if(row_num == undefined || row_num == null || row_num <</span> 0) {
throw new Error( "Invalid row_num specified." );
}

}
// do nothing. simple label
Selenium.prototype.doLabel = function(){};
Selenium.prototype.doGotoLabel = function( label )
{

throw new Error( "Specified label '" + label + "' is not found." );
}
this.continueFromRow( gotoLabels[ label ] );

}
}
Selenium.prototype.doEndWhile = function()
{
var last_row = testCase.debugContext.debugIndex;
var while_row = whileLabels.ends[ last_row ] - 1;
if( undefined == while_row ) throw new Error( "Corresponding 'While' is not found." );
this.continueFromRow( while_row );
}
Selenium.prototype.doPush= function(value, varName)
{
if(!storedVars[varName]) {
storedVars[varName] = new Array();
}
if(typeof storedVars[varName] !== 'object') {
throw new Error("Cannot push value onto non-array " + varName);
