Writing REPL scripts on side-by-side Chrome and IE

Following the Chrome-Hijacking posts, I’m starting to convert the WatiN Extension methods into ChromeDriver, and to do so needed to execute requests side-by-side (to test the APIs and to be able to write UnitTests for them).

To do that (side-by-side Chrome and IE execution) I wrote this script:

//var topPanel = panel.add_Panel(true); 
var topPanel = "Util - REPL IE (native) and Chrome (hijacked window)".popupWindow(1200,600);
var browsersPanel = topPanel.insert_Above();   
var ie        = browsersPanel.title("IE").add_IE();   
var chrome = browsersPanel.insert_Right().add_Chrome();      
 
var repl = topPanel.add_Script();
repl.add_InvocationParameter("ie", ie);
repl.add_InvocationParameter("chrome", chrome); 

var firstScript = 
@"chrome.open(""http://o2platform.com"");
ie.open(""http://o2platform.com"");

//return ie;
return chrome;

//O2Ref:" + @"WatiN.Core.1x.dll
//O2Ref:" + @"WebDriver.dll
//O2File:" + @"WatiN_IE_ExtensionMethods.cs
//O2File:" + @"API_Chrome_Hijack.cs
//O2File:" + @"API_ChromeDriver.cs
";
repl.onCompileExecuteOnce()
    .set_Code(firstScript);
//chrome.open("http://o2platform.com"); 

//O2Ref:WatiN.Core.1x.dll
//O2Ref:WebDriver.dll
//O2File:WatiN_IE_ExtensionMethods.cs
//O2File:API_Chrome_Hijack.cs
//O2File:API_ChromeDriver.cs


which when executed looks like this:

For example here are both browsers opening up the 'http://whatismybrowser.com site:

We can also start to test the APIs and see if they produce equivalent results.

For example, if we execute this script:
chrome.open("http://o2platform.com");
ie.open("http://o2platform.com");

chrome.elements().tagNames().showInfo();
ie.elements().tagNames().showInfo();

//O2Ref:WatiN.Core.1x.dll
//O2Ref:WebDriver.dll
//O2File:WatiN_IE_ExtensionMethods.cs
//O2File:API_Chrome_Hijack.cs
//O2File:API_ChromeDriver.cs


... we will get two popup-lists with the list of Html Tag names (as seen by each browser):
