I am sorry but I no longer recall why, probably it was just a question of the time available.

Thanks,

Thanks Rob for the quick response. Yes , i will try to implement the code base and if it is done i will let you know.

Thanks,

Sorry, but there is no documentation that goes with the code. However, I hope you will find the code fairly easy to follow. If you have any specific questions then let me know.

Rob

I am not personally aware of any other solutions, but that is not to say they don't exist. Have you considered modifying the source code to add the support you need?

Hi Rob,

Thanks for the response.
Yes, my trace file contains too many xml types. So i would be quite difficult to replace all of them manually.

Is there any other solution available to resolve this ?

Unfortunately, as stated on the home page, the tool does not support XML data types. Does your trace contain a lot of XML data types? If it is not a lot then perhaps it would be possible to add those in by hand?

New Post: customizing parameters

robjarratt — Fri, 01 Feb 2013 14:38:44 GMT

For parameter customisation the only thing I can think of to make it easier is to consider data-driven tests. It would still need some effort to put it in, but you could drive the actual data from spreadsheets etc.

Think time is generally done in the load test setup rather than in individual unit tests. That said, I did think at the time of making use of the timing information that is available from the trace, but this is not currently implemented.

There is no log file for queries that are not generated. It logs the filtered out queries to the console. Basically it filters out anything against the master, model and msdb databases, and calls to sp_reset_connection.

It was always my intention to add prepared statements, but finding the time is very difficult.

New Post: customizing parameters

ksharp — Thu, 31 Jan 2013 23:51:48 GMT

Very nice tool but I have few questions?

Is there easier way to customize parameters for queires and SPs? We have thousands of queries/SPs that get executed on the SQL server.

How do we handle thinktime within the generated Unit test code? Is there way to add the thinktime as it was read from the tracefile?

Is there a log file created for the queries that do not get generated? Number of queries generated in the code ( in Statement()) not matching the number of the queries in the trace file.

Are you planning to update the tool with prepared statements? Do you have any suggestions on how to add the prepared statments in the unit test code?

THanks in advance

New Post: Why delegate?

nyet — Wed, 05 Oct 2011 18:20:56 GMT

Yeah, I am having a problem understanding which piece of code were executed for the anonymous delegate, thus making the project upgrade rather slow...

If I decided to release upgrade, would you review it? Maybe I broke something

New Post: Why delegate?

robjarratt — Wed, 21 Sep 2011 07:09:00 GMT

That is the syntax for an anonymous delegate, I probably thought that it wasn't worth writing a whole new method for those brief bits of code. At the time I was not very familiar with lambdas, and indeed they may not even have been available when I wrote that code (can't remember now).

Can you explain why do you need to use delegate in this particular instance?

[TraceFileProcessor.cs]

               UnitTestGenerator utg = new UnitTestGenerator(scenarioName, scenarioName, scenarioName + "Tests", TestMethodMode.ScenarioMethodOnly, OperationTimerMode.IncludeOperationTimers);

                TraceParser parser = new TraceParser(reader);
                parser.ProcessingTraceRecord += delegate(object sender, TraceRecordFilterEventArgs trfea)
                {
                    if (ProcessingTraceRecord != null)
                    {
                        ProcessingTraceRecord(null, trfea);
                    }
                };

                utg.GeneratingCall += delegate(object sender, GenerateCallEventArgs gcea)
                {
                    if (codeGen != null)
                    {
                        Console.WriteLine("   UnitTestGenerator.GenerateCall(2.0)");
                        gcea.Handled = codeGen.GenerateCall(gcea.Command, gcea.ScenarioMethod, gcea.StubType);
                    }
                };

                SqlParser sqlParser = new SqlParser();
                while (true)
                {
                    TraceRecord traceRecord = parser.Parse();
                    if (traceRecord == null)
                    {
                        break;
                    }

                    string lastSqlParsed = traceRecord.TextData;
                    if (ParsingSql != null)
                    {
                        ParsingSql(null, new SqlEventArgs(lastSqlParsed));
                    }

                    ParsedSqlCommand cmd = sqlParser.ParseTraceRecord(traceRecord);
                    try
                    {
                        utg.GenerateCall(cmd);
                    }
                    catch (Exception ex)
                    {
                        throw new InvalidOperationException(string.Format(CultureInfo.CurrentCulture, Messages.Processor_ErrorProcessingParsedCommand, lastSqlParsed, ex.Message), ex);
                    }
                }

New Post: Problem on running the load test tool

It would seem likely that there is still a dependency missing. Can you use the Fusion Log Viewer to find out which assembly it thinks is missing?

Thanks

New Post: Problem on running the load test tool

rajibpradhan — Thu, 21 Jul 2011 09:08:25 GMT

Hi Rob,

I have generated a trace file from SQL server 2005 running on Windows server 2008 R2.

I have installed SQL server 2005 (with management tools), SQL server 2005 SDK in my client machine. Then I downloaded the SQL load test tool and copied to

one folder in the C:\ drive. Then I installed Visual studio 2005 Team Edition.

When I am executing the tool with the trace file, I am getting the following error:

C:\SQLLoadTest>DbLoadTestGen.exe testScenario trace1.trc
Cannot read the trace file trace1.trc, please ensure it is a valid SQL Profiler trace file.
Failed to initialize object as reader.
The specified module could not be found. (Exception from HRESULT: 0x8007007E)

I think this is due to the incompatible trace file.

Please provide some input about this problem.

Thanks and Regards,

The download includes a usage notes document which tells you what you need to know. There are no specific instructions for 2008 as the update posted in October 2008 just includes a new template for 2008 profiles.

I am really sorry I missed the posting from June, not sure what happened there.

The usage notes document in the download includes the following statement: "Make sure SQL Server 2005 SDK and the SQL Server 2005 Management Tools are installed." Please check that these pre-requisites have been satisfied.
