Web service load test test using visual studio 2010 - web-services

How to write custom web service load test:
All my web services has byte[] (byte array) as input and output.
Internally we have xml as input and ouuput which we encrypt and decrypt in custom way.
I checked that I can write down the custom validatation rule using visual studio. But can i also customize the input. (i.e. I pick the input load data from csv/xml and perform the required encrypt/decript before sending the the server)
Does the web service load testing supports the https communication?
Thanks and Regards,
Hardik

First, you have to create the Web Performance Test that will be used by the Load Test. Check these walkthroughs which will help you to find out:
How to change the code of a recorded Web Performance Test
How to data bind a Web Performance Test
How to add validation rules to a Web Performance Test
Also I believe that this guide will be very helpful to troubleshoot any possible issue
As far as I know there is no restriction on tesing HTTPS services through a Web Performance Test
*I suggest to check the option of Unit Test as well. I have tried it and in my opinion they are more easy to create them. Of course, this is your choice.

How to test SharePoint 2010 Web Services

Is there a way to test sharepoint 2010 web services methods? Either using browser and modify the url or some kind of free tool to test web services. SharePoint web services looks like http://intranet.site.com/_vti_bin/webs.asmx. Some methods does not take parameter and others do.
Just want to be able to test methods using tool or if browsers allows it.
This tools http://www.xyrow.com/Home/Free seems to be light weight and serves the purpose.

How to create a web service load test using Visual Studio 2010?

Is there a way to test a Web Service using VS2010 like it's used to test a web site?
For a web site I can create a set of WebTestRequest objects that emulate the loading and the parsing of a web page from the test and then, implementing the GetRequestEnumerator I can yield results to the load test so that the execution time and payload of any single page could be evaluated by the test runner and published in my test run reports.
I would like to do the same for a test using web service call so that each time I call the web service (there is some logic in calling it, like logging in, getting a security token and pass a proper formatted XML document to the web service method) I can yield the result to my test runner and evaluate it.
Is there a way to do it or do I need to implement a specific class inheriting from the WebTestItem abstract class?
Regards

Yes, it is possible to test Web Services using Web Performance Tests in Visual Studio 2010 Ultimate.
Here's a couple of useful links:
How to: Create a Web Service test (MSDN)
How to: Web Service Load Testing Using VSTS 2010 (Blog)
As a starting point, you can use a web proxy tool like Fiddler to intercept the HTTP requests made to the Web Services, copy the contents of the SOAP envelopes in the Web Performance Tests and then tweak them accordingly based on the test scenario you want to simulate.
This doesn't quite answer your question as it's a 3rd party tool, but SOAP UI is a great piece of (free) software for load testing web services, whether your own or someone else's. You can run individual requests, or do a bunch of different load tests.
We've used it for one service that uses credentials, so I'm sure it will work fine for your scenario.

Building web services without a web server

OK, this is impossible, but I will try to explain the situation here.
Let's say we have cases, that we need a fast setup of a web server in order to have a simple soap web service running (querying a db and so on).
In VS though, upon debugging a web project, it creates a quick ASP.NET development server without relying on the actuall IIS that might be installed on the PC.
Is there any project that does something like that?
This would be ideal for small projects, where a simple executable would get a server ready to go and would allow web services to be executed right away.
I have looked at some stuff over the net like http://msdn.microsoft.com/en-us/magazine/cc163879.aspx and http://mtaulty.com/CommunityServer/blogs/mike_taultys_blog/archive/2004/05/24/4479.aspx but they seem to be quite outdated and i am not sure how well they work (havent tested them thoroughly)
EDIT: I have build an application like the one you suggest. However, how can i implement HTTP GET/POST requests to the service using this method? I tried using WebGet after my operationcontract but it didnt work. For example, my service is at http://localhost:8080/Service and i would like to use it such as http://localhost:8080/Service/getMethod?x=2.
I believe that the development server used by Visual Studio is based off of the Cassini code base (of which there is a fork here). I also found this article on hosting the asp.net runtime. It was also created a while back (2004), but has been updated since (2008). I think a lot of the core concepts are probably still the same.
Another approach would be a roll-your-own web server using the HttpListener class. This could take some work if you want to use it for hosting asmx type services, but if you were doing RESTful services, it isn't too bad of an option (this is actually how RavenDB works if you are not hosting it under IIS).
A WCF service can be hosted in almost any kind of application, including a Windows Service or a console application. There is no need for a web server at all.
Alright,
i've done it so im posting it here to help anyone who has issues with similar problems.
Create your WCF Service file as usual and then by using ServiceHost (or WebServiceHost) you can easily create a WCF service.
In order to use GET http requests to make it simple to communicate with mobile devices (such as iphone) you can use WebGet above your service methods and make sure you manually add a service endpoint using WebHttpBinding for WebServiceHost or WebHttpBinding with an WebHttpBehavior for ServiceHost.
Then you can call your service methods such as http://localhost:port/webhttpendpointaddress/mymethod?x=2.

Web service testing framework with interface for business users

I'm looking for a web service testing framework that has a good built in text input / output gui. The point would be for business and other non developer users to be able to test requirements by using a simple gui that they could enter values into and see the results from the web service. I have seen lots of references on Stack Overflow and the web to great developer web service testing tool but a nice, built in, I/O gui is the key feature for me.
By web service testing I mean a tool that sends xml post requests over HTTP and tests the response.
I have been trying out fitnesse but to use it I need to cut out parts of the system and I very much want to do end to end testing. The way fitnesse displays its results is great but the wiki data entry is a bit clunky for business users imo.
We use FitNesse for the most part. The developers maintain a fixture that s the connector between your app and the FitNesse server. The business user can write the test cases in an wiki style. Works fine for us.
Rational Functional Tester was in the discussion too. However, I have never seen it, but would have met our requirements too.
You might want to look at the robot framework. It's a pretty decent testing library which makes it easy to test web services. There is also a library that integrates Selenium into the framework for front-end testing. Tests can be specified in a couple of plain text formats as well as in HTML tables. You also have the option to let users create test data in spreadsheets if you like, then save them in a tab-separated format.
Look at WebServiceStudio http://www.codeplex.com/WebserviceStudio
We use Concordion for business testing. It's very similar to Fitness but the input files are HTML files "executed" by JUnit.
If your web services don't take 500 parameters, a HTML table is a great way to define input values. I agree, there no UI (although a WYSIWYG HTML editor would do it) but the benefit is that your tests can be checked into Subversion (for example), executed regularly (read every night) and the result HTML files be published internally.
I found testing composite application in Netbeans very easy to use ...
As you requested in your question you can define an input XML and a desired output XML, and when you run the test you have a classic JUnit result like this :

Here you can find a good example:

I use NetBeans 6.5.1 bundled wit GlassFish ESB 2.1 ... I'm not sure that this feature is supported in the newest NetBeans Versions

How do I test webservices?

I am a novice in web services. I am totally new to testing web services.
A new project demands that I test the web services, and the customer is in favor of any open source tool.
What is the approach to testing web services?
Also Please suggest a tool(with minimal scripting) to test web services?
Check out SoapUI - one of the best web service test tools - plus it's free!!
They also have a "Pro" version which costs - you can do more stuff, like load testing etc., but the free version is quite good enough for most of your testing, I'd say!
Given a WSDL (online or stored as file), it'll create stubs for each method, which you can then use to create requests (as XML), fill in the blanks (the parameter values), and then you can send off your request to the web service and see what comes back as a response.
SoapUI also allows you to write scripted tests than can be run over and over again.
Excellent tool - can't praise it enough!
Marc
Additionally you could use Firefox Poster in order to test your web service by passing XML-packets manually.
Check it here:

SoapUI is a great tool to test SOAP webservices. It allows you to test a SOAP client or a SOAP server.
Another very useful tool is Fiddler. Fiddler isn't necessarily aimed at testing webservices (it's a HTTP debugger), but since SOAP webservices run over HTTP, you can use it to testing. Another very important advantage of using Fiddler is the fact that you can test REST webservices also.
You might want to consider robot framework. It is a generic, keyword-driven testing framework. There are libraries for testing REST and SOAP based web services. It can also be used to test web pages (via a selenium library), databases, and a whole lot more.
robotframework has a ton of built-in keywords, and there are additional libraries that do much more. You are also able to develop your own keywords in python, java, .NET languages, or any other language.
