Hi Shirirang,
"Is there a way to run debugger of IE developer tools while simulating user actions on the AUT and capturing the errors and exceptions in test log."
-For this you can use this piece of code to access the console and check its text, if this is what you need (I couldn't make the [CTRL+2] shortcut work)
//opens the dev tools
Sys.Browser("iexplore").Page("*").Keys("[F12]")
//Sys.Browser("iexplore").Page("*").Keys("[Hold]^2")->couldn't make this work
Sys.Browser("iexplore").BrowserWindow(0).Window("Frame Tab", "", 1).Window("F13FrameWindow", "F12", 1).Window("F12BrowserToolWindow", "", 1).Window("Shell Embedding", "", 1).Window("Shell DocObject View", "", 1).Window("Internet Explorer_Server", "", 1).Page("res://C:\\Program Files\\Internet Explorer\\F12Resources.dll/23/header/header.html").Nav("tabContainer").Panel("tabListContainer").TextNode(1).Click()
//check the output text of the console
Sys.Browser("iexplore").BrowserWindow(0).Window("Frame Tab", "", 1).Window("F13FrameWindow", "F12", 1).Window("WTL_SplitterWindow", "", 1).Window("F12BrowserToolWindow", "", 1).Window("Shell Embedding", "", 1).Window("Shell DocObject View", "", 1).Window("Internet Explorer_Server", "", 1).Page("res://C:\\Program Files\\Internet Explorer\\F12Resources.dll/23/console/console.html").Panel("mainContainer").Panel("outputArea").Panel("outputList").contentText
After this you just need to analyse the output of the console whenever you want
