I have some relatively simple transactions that run against my application like "start user session" which typically takes a couple seconds when running a VS project through SilkPerformer. When I try to execute the same transaction using the VS 2015 performance testing tools (locally on the controller) the response times are roughly twelve seconds longer, repeatedly.
I have a transaction logger that captures the response times of each transaction so I can see them individually during the execution in VS and I'm wondering if I'm missing a setting somewhere or there is a configuration change I can make to the project because it almost seems as if the project is pacing the execution of the transactions. I get the same behavior whether running on an agent or the controller directly so it doesn't appear to be network related.
This is a sample of the code that's executing:
public interface ITestTransactionTimer : IDisposable { }
public class TestTransactionTimer : ITestTransactionTimer
{
public TestContext TestContext { get; private set; }
public string TransactionName { get; private set; }
public TestTransactionTimer(TestContext testContext, string transactionName)
{
this.TestContext = testContext;
this.TransactionName = transactionName;
this.TestContext.BeginTimer(this.TransactionName);
}
public void Dispose()
{
this.TestContext.EndTimer(this.TransactionName);
}
}
public class NoOpTestTransactionTimer : ITestTransactionTimer
{
public void Dispose() { }
}
protected ITestTransactionTimer LogTransaction(string transactionName)
{
if ((null == this.TestContext) || !this.TestContext.Properties.Contains("$LoadTestUserContext"))
{
return new NoOpTestTransactionTimer();
}
return new TestTransactionTimer(this.TestContext, transactionName);
}
private TestContext testContextInstance;
public TestContext TestContext
{
get { return testContextInstance; }
set { testContextInstance = value; }
}
//starting User Session
[DataSource("Microsoft.VisualStudio.TestTools.DataSource.CSV", "C:\\Path\\Data.csv", "Data#csv", DataAccessMethod.Sequential), DeploymentItem("C:\\Path\\Data.csv"), TestMethod]
public void smokeTest()
{
sUserName = "domain\\"+TestContext.DataRow["user"].ToString();
sPassword = TestContext.DataRow["password"].ToString();
prospectClientId = TestContext.DataRow["prospectClientId"].ToString();
accountNumber = TestContext.DataRow["accountNumber"].ToString();
correlationId = "startUserSession - " + obj.ToString();
// Start User Session
using (this.LogTransaction("t1_startUserSession"))
{
ChannelFactory<IAppShellService> cfsus = null;
try
{
using (ChannelBuilder.mPContext(ref appShellServiceClient, "IAppShellService", sUserName, sPassword, 0, null, correlationId, false, effectiveDate, ref cfsus))
{
var userSessionResult = appShellServiceClient.StartUserSession();
}
}
catch (Exception ex)
{
Console.WriteLine(ex);
}
finally
{
cfsus.Close();
}
}
}
