I am trying to use the HTTP proxy with the code in the block below. The Set web proxy set is run as step 1 of the test to initialize the settings and relaunch the browser. When I get to the AddBeforeResponseListener I am getting a null reference exception( Object reference not set to an instance of an object..) I am clearly missing an initialization step somewhere but I am not sure where.

I am use the TS plugin version 2012.1.420.0 with VS2010 on a win7 64 bit box.

[CodedStep(@"Set WebProxy")]

public void TradeList_CodedStep4()

{

ActiveBrowser.Close();

Manager.Settings.Web.UseHttpProxy = true;

Manager.LaunchNewBrowser();

}

[CodedStep(@"Click 'ContentPlaceHolderRwDldFilesCLbGenerateBulkReportLink'")]

public void TradeList_CodedStep3()

{

ResponseListenerInfo li = new ResponseListenerInfo(GetFileFromHeaderInfo);

Manager.Http.AddBeforeResponseListener(li);

// Click 'ContentPlaceHolderRwDldFilesCLbGenerateBulkReportLink'

Pages.TamaracIncCom7.ContentPlaceHolderRwDldFilesCLbGenerateBulkReportLink.Click(false);

Manager.Http.RemoveBeforeResponseListener(li);

//string getPostBack = (string)GetExtractedValue("BulkReportJavaScript");

//string parsedPostBack = getPostBack.Substring(11);

//var response = Actions.InvokeScript(parsedPostBack);

}

private void GetFileFromHeaderInfo(object sender, HttpResponseEventArgs e)

{

System.Collections.Specialized.NameValueCollection headers = e.Response.Headers;

}

Hello Daniel,

The issue is that your setting to turn on the HttpProxy is not being respected, and there's nowhere to turn it on through the UI for Quick Execution. (It exists for Test Lists, however). There's an existing feature request for this and you can vote for it here.

In the meantime, here's a work-around:

1. Disable the first coded step in the TradeList test.
2. Create a new parent test and add a coded step that does the following:

[CodedStep(@"New Coded Step")]

public void ProxyParent_CodedStep()

{

Settings settings = new Settings();

settings.Web.UseHttpProxy = true;

ResultSummary results = RunHelper.Test(@"C:\Users\rinaldi\Documents\Visual Studio 2010\Projects\TestProject3\TestProject3\Tests\ProxyStuff.tstest", settings, @"C:\Users\rinaldi\Documents\Visual Studio 2010\Projects\TestProject3\TestProject3\bin\Debug\TestProject3.dll");

}
