WCF Load Test

New Post: Could not find method for SOAP action "http://xxxxx", check that the right proxy assemblies have been supplied.

I can understand that you can't send out any information, but it does make diagnosis rather more difficult. Can you give me any information at all about the contract? Could you send me perhaps the signature of the operation that is not working? I note that you are using a service-side trace, but the assemblies that you need to reference must contain either the contract or be client-side assemblies containing the proxy class.

It should not matter that you are not setting the Action parameter.

If you have not done so already, it really is a good idea to run through the lab first to get a feel for how it works, and to prove to yourself that it does actually work (!)

You could also run the command line version of the tool and configure it to create a trace to see if that offers any clues.

Thanks for replying so quickly.

I was hoping it was just a bad config setting or something simple.

I can't send the files out of the building, but I'm working thru the Using.docx I found in the LAB folder.

Also, we're not explicitly setting the action using the Action= parameter on the OperationContract attribute.
Could this be a contributor to the issue?

Thanks for your help.

I would need the information required to reproduce the problem, ideally the trace you are using and the assemblies you are referencing. I think you can contact me directly by clicking on my alias, we can then get in direct email contact to get traces etc.

Also, the tool does using System.Diagnostics.Trace so if you configure this in its config file you could send me the tool trace or see if it offers you any clues.

Greetings,

I'm using the VS wizard and a pre-captured server-side trace file, but after selecting the correct assemblies and clicking Finish, I get a "Test Generation Error":

"Could not find method for SOAP action "http://xxxxx", check that the right proxy assemblies have been supplied."

Any suggestions would be greatly appreciated.

Commented Issue: Fail to generate unit tests on contracts that don't explicitly set the action

crash8088 — Wed, 03 Sep 2008 20:38:55 GMT

When a contract doesn't explicitly set an action named parameter on a contract we get the error

"Could not find method for SOAP action "http://xxxxx", check that the right proxy assemblies have been supplied."

This happens with a server trace and the correctly supplied contract.

If we explicitly set the action using the Action named parameter on the OperationContract attribute the unit tests are generated without any problem.

I am unable to get past this error message. I'm getting it on 2 machines (VS2005TE & VS2008CTP). I've tried several configurations but always get the same error. Any idea what the configuration problem might be?

Commented Issue: Unable to Create Test for messages containing XElement types

robjarratt — Sat, 26 Jul 2008 06:19:39 GMT

On contracts with XElement types, the Scenario Wizard generates the following error:

"Data or message contract attribute expected on type System.Xml.Linq.XElement"

Adding a client proxy or System.Xml.Linq to assemblies list does not solve the problem.

This one requires a bit of investigation, I have not looked much at Linq so far.

New Post: "The trace file did not contain any usable data"

robjarratt — Sat, 26 Jul 2008 05:45:54 GMT

This is likely to be a mismatch between the config file and the trace file. Try changing the clientTrace setting in the config file, or if you are using the wizard check the server-side option. Aplogies for the dealy in replying.

New Post: "The trace file did not contain any usable data"

Hi,
I tried the wcfunit command-line-tool with a simple wcf-project (to be exact its just the sample-project that visual studio creates if you setup a new wcf-service-library project). I enabled the message logging on the service level and started the project to generate some entries in the message log. After that I tried to create the wcf load unit tests with the command-line tool. Unfortunately wcfunit gives me an error: "The trace file did not contain any usable data. Please make sure that LogMessageAtServiceLevel and LogEntireMessage are set"
Has anyone an idea what i am doing wrong?

ps: here is the message log:

COMMENTED ISSUE: WCF Test Wizard don't release assemblies after creation of the test

robjarratt — Wed, 16 Apr 2008 20:51:58 GMT

The Wizard used to create WCF Test don't release assemblies after creation of the test.
When we build the solution, Visual Studio can't delete the dll in \bin\Debug directory because there are in use by another process.
Comments: ** Comment from web user: robjarratt **

I need to look at this but I suspect that I would need to change the design so that the tool works in a different appdomain so that the assemblies are unloaded after the tool has been run.

COMMENTED ISSUE: Using contracts with parameters passed by reference

robjarratt — Wed, 16 Apr 2008 20:49:25 GMT

It's not possible to use contracts with parameters passed by reference in current version of WCF Load Test (2.0) - Release 10153

Example :
[OperationContract]
string HelloWorld(ref int Counter);

First, I create a WCF Test in Visual Studio and select trace file, contracts and assembly.
When I go to last step, I get an error "Type System.Int32& cannot be serialized. Consider marking it with the DataContractAttribute attribute, and marking all of its members you want serialized with the DataMemberAttribute attribute."

Could you help us ?

Thank you.

Regards

Arnaud

This is indeed a bug. I am working on a fix.

Project Description

This tool takes a WCF trace file and a WCF client proxy, or a WCF interface contract, and generates a unit test that replays the same sequence of calls found in the trace file. The code generated is easily modifiable so that data variation can be introduced for the purpose of doing performance testing.

The tool will also integrate with Visual Studio 2005/2008 Team Edition for Software Testers and installs a wizard for creating the trace and processing it from inside Visual Studio.

Features

The tool has the following main features:

Replay of captured scenario in a unit test that can be included in a load test.
Support for the DataContractSerializer.
Support for message contracts.
Support for proxies generated using svcutil.
Support for clients that create proxies at run time from contract interfaces.
Supports calls to multiple services in a single scenario.
Supports multiple calls to the same service operation.
Filtering by SOAP action of which messages in the trace to replay.
Readable and modifiable code is generated.
Automatic association of trace message with proxy method (requires all operations to have a unique SOAP action).
Support for client and server side traces.
A command line tool for processing traces and generating code.
Visual Studio 2005/2008 integration (Team Developer, Team Test, Team Suite and for 2008 also Professional)) that can be used instead of the command line tool.
