Test a WCF service with SOAPUI

With help of SOAP UI you can easily test your webservices. In this pos tI’m going to test a WCF web service (yes MS WCF; not my favourite company and technology but anyway….)

First create your webservice. Within Visual Studio goto File -> New Project . Choose Visual C# and select  WCF Service Application

Create new project

Now start your project by pressing F5; the service, together with the WCF Test Client, will start and there are two methods available on this service:

GetData and  GetDataUsingDataContract

The WCF Test client

Play around with the WCF Test Client to get the idea of how this works. Next we will install SOAP UI. Download your copy here. Install SOAP UI using the default settings.

After installation start SOAP UI and create a new project. Goto File -> New soapui Project . Fill out the dialog as shown below (don’t forget to add the ?wsdl ):

 Press Ok; a new soapui project will be created. See the image below:

Now you can execute the same request as the WCF Test Client did; but there is more; much more!

Right click on the WCFTestService1 and choose New TestSuite.

Press OK. Right click on TestSuite 1 and choose New TestCase:

Press OK. Right click on Test Steps choose Add step and then Test request.

Press OK. Choose the operation you want to test:

Press OK. On the next screen leave things as suggested

Press OK. Your first test request is added to the TestCase.  By double clicking the TestCase 1 item and pressing the play button the test will be excuted. As you expected the test will succeed and a green icon is shown right before the test request entry:

Now lets add some testdata to the request. Place the following XML in the test request XML window. First select the xml view:

Now paste the XML below into the request:

Now you can add assertions to your test script to make sure the operations works the way you want. For example lets assert that the GetDataResult field contains the text “You entered: 3”. Press the plus sign next to the play button:

Select the SOAP response assertion:

Give the assertiona unique name:

Type the text you want to look for in the response.

Now if you execute the request it will still succeed because the request contains the number three. Change this number to, for example 4, and you will see that the assertion fails.

Working with Visual Studio 2010 and github on Synology

gitInstall the  "GIT server"  package on your Synology Disk Station. Goto the package center and search for the “Git Server” package. Download and install it.

Install GitExtensions on your dev box.

Install the latest msysgit on your dev box.

Install the  "Git Source Control Provider"  Visual Studio 2010 extension on your dev box. In Visual Studio goto Tools -> Extensions and search for “Git Source Control Provider” in the online gallery.

Now SSH to your Synology (either with putty or with a Linux terminal) and execute the following commands:

This will create a so called “bare git” repository. A bare git repository can be used as a central repository to which you push your local repositories.

Ok; now there is a GIT repository created on your Synology. Next create a new Visual Studio solution. Right click the solution name and select “Create Git Repository”. This will add an .git folder to your solution directory and now your solution is in a local Git repository.

Next commit your new solution to the Git repository.Select all files; type your comment and hit “Commit”.

Now push your local repository to the central bare git repository you created earlier. Right click the solution name; choose Git (master) -> Push. The checklist for Git settings will show up if not all settings are valid. For now just click Ok. The Push dialog appears. Specify the remote name; for example: ssh://johndoe@10.0.0.1/volume1/repo1.git

Some useful GIT commands
In Visual Studio goto GIT -> GIT bash; a Bash command prompt will start.
Show available tags:

Create a tag in the GIT bash:

Commit your changes with a message:

Push the tag information:

Delete a tag:

GIT Use Case

Create bare repo on diskstation

On a client clone (initialise) a repository from the dskstation:

[Remote “origin”] can be found in .git/config file; you could add an alias for convenience. A directory repo will be created that contains your files. Add files to your repo directory

Add them to the local stage:

Commit them to the local repo:

Push them to the server repo:

A new branch master will be created. From now on you can use git push (without the origin master)

Scanning an image with C#

This post shows an example of scanning an image with C#. First of all start Visual Studio and create a new console application.scanning software c#

In this example I make use of the standard WIA scanning functionality in Windows 7. Reference the WIA dll in your new project. The dll can be found in the folder “c:\windows\system32\wiaaut.dll”.

The code below scans an image (A4 size) at the default 300 DPI and stores it as an uncompressed TIFF image.

SoapUI and WCF Service testing

Test with SoapUI: modify the generated web.config

soapUI_header_logoThe web.config that is create when you create a new WCF service application does not work with SoapUI. Retrieving the WSDL will work fine but when you execute a operation on the service the following message will appear:

A solution to this problem (at least for testing purposes) is to add a custom wsHttpBinding. Create a new WCF Service application C# project. Delete all text from the web.config and add replace it with the markup below.

Important to note is that we have a custom wsHttpBinding with the security mode set to “None”. This is necessary for SoapUI to work with this service!

Now you have to create a new SoapUI project. Point it to the ?wsdl for this services and the project is created with a default request for all operations. Open the first request and press the WS-A button (on the bottom of the request editor). Check “Enable WS-A addressing”, “Add default wsa:Action” and “Add default wsa:To”.

Now execute the request and you get a proper response!
