What is the Best Way to Grab the Iteration Value in a Sweep/Repeat Step?

I’m trying to pass the Iteration Value of either of these flow control steps to a Result Listener. What is the best way to have a result listener access this data? I’m trying to have my Result Listener print this value OnTestStepRunStart/Complete.

Hello Ivan,

I would access the iteration resource from the parent and then publish the string so the result listener can grab it. First I added a reference to the package OpenTap.Plugins.BasicSteps:

Then I added a test step which access the parent resource:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.ComponentModel;
using OpenTap;

namespace OpenTap.Plugins.Test1
{
[AllowAsChildIn(typeof(OpenTap.Plugins.BasicSteps.RepeatStep))]
[Display(“PrintIteration”, Group: “OpenTap.Plugins.Test1”, Description: “Insert a description here”)]
public class PrintIteration : TestStep
{
public string TableName { get; set; }
public string ColumnName { get; set; }

    public PrintIteration()
    {
        TableName = "SomeTableName";
        ColumnName = "SomeColumnName";
    }

    public override void Run()
    {
        // Get Iteration info from parent step
        String strIterationInfo = GetParent<OpenTap.Plugins.BasicSteps.RepeatStep>().IterationInfo;
        Log.Debug("Iteration Info: " + strIterationInfo);

        // Publish so result listener can get this
        Results.Publish(TableName, new { ColumnName = strIterationInfo });
    }
}

}

The test step is allowed as child in a Repeat step, every time the test is executed the Parent.IterationInfo is obtained and published, the highlighted rows show the iteration info string:

Then you can access it from your custom result listener.

Let me know if this helps,

Another thumbs up as the iteration output is calculated differently in repeat and sweep steps. When simply accessing the iteration string of a sweep I was getting system errors but it worked fine when accessing the same output in a repeat step. I assume the failure has something to do with the Lambda function, but accessing via Parent gets around the issue.
