Running unit tests using MSTest from console application

There are times when you end up with a requirement like this:
You should be able to run Unit Tests from console application.
And yes, we are talking about MSTests. Well, this is not very complicated using MSTest.exe
Mstest  /testcontainer:[pathToOurTestComponent.dll]
After a few day you end up with a new requirement:
Run Unit Tests using a console application from a machine that doesn’t  
have Visual Studio installed
Using different scripts from internet (like this one: http://mindinthewater.blogspot.ro/2011/02/executing-visual-studio-2010-unit-tests.html), you end up with a configuration that can be used to run unit tests on machines that doesn’t have Visual Studio.
Mission complete? Yes.
But, you have a problem. Yes, there is a but. What about licensing? Are you allowed to do something like this?
Depends of the person who run your console application. You are allowed to do something like this as long the person who run the console application has a Visual Studio license. This is needed because MSTest component is not allowed to be redistributed based on the current license.
What should I do if clients don’t have a Visual Studio licence?
You could try to use NUnit or other unit test frameworks. There are a lot of frameworks free of charge that can be used.
Below you can find script that extracts the assemblies needed by MSTest if you are using Visual Studio 2013. The script is written using the example written by Wim Coenen for VS2010 (I updated them for VS2013).
The only thing that is missing is the command to extract the registry information needed by MSTest.
@echo off
setlocal
set here=%~dp0

mkdir mstest
set targetfolder=%here%mstest

set programs=%programfiles%
if exist "%programfiles(x86)%" set programs=%programfiles(x86)%
set vs2013="%programs%\Microsoft Visual Studio 12.0"
set gac2="%windir%"\Microsoft.NET\assembly
set gac1="%windir%"\assembly

echo === Copying from Visual Studio 2013 install folder...
copy %vs2013%\Common7\IDE\mstest* "%targetfolder%"
copy %vs2013%\Common7\IDE\PrivateAssemblies\Microsoft.VisualStudio.Quality* "%targetfolder%"

echo === Copying from %gac1%...
pushd "%gac1%"
dir /s /b *.dll | findstr QualityTools | findstr 12.0.0.0 > %here%tmp.filelist
popd
for /F "tokens=*" %%f in (tmp.filelist) DO copy "%%f" "%targetfolder%"

echo === Copying from %gac2%...
pushd "%gac2%"
dir /s /b *.dll | findstr QualityTools | findstr 12.0.0.0 > %here%tmp.filelist
popd
for /F "tokens=*" %%f in (tmp.filelist) DO copy "%%f" "%targetfolder%"

del tmp.filelist

echo === Done. Check output for errors!
exit /b 0

  1. It should be possible to install MSTest on a server by installing just the test agent (http://www.microsoft.com/en-us/download/details.aspx?id=38186 ) but I'm not sure about the licensing part..

    1. In our case we don't talk about servers. My case was simple users that wanted to run some unit test on their local machines to validate different things.

How to check in AngularJS if a service was register or not

There are cases when you need to check in a service or a controller was register in AngularJS.
For example a valid use case is when you have the same implementation running on multiple application. In this case, you may want to intercept the HTTP provider and add a custom step there. This step don’t needs to run on all the application, only in the one where the service exist and register.
A solution for this case would be to have a flag in the configuration that specify this. In the core you would have an IF that would check the value of this flag.
Another solution is to check if a specific service was register in AngularJS or not. If the service was register that you would execute your own logic.
To check if a service was register or not in AngularJS container you need to call the ‘has’ method of ‘inhector’. It will return TRUE if the service was register.
if ($injector.has('httpInterceptorService')) { $httpProvider.interceptors.push('httpInterceptorService&#…

ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded

Today blog post will be started with the following error when running DB tests on the CI machine:
threw exception: System.InvalidOperationException: The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information. at System.Data.Entity.Infrastructure.DependencyResolution.ProviderServicesFactory.GetInstance(String providerTypeName, String providerInvariantName) This error happened only on the Continuous Integration machine. On the devs machines, everything has fine. The classic problem – on my machine it’s working. The CI has the following configuration:

[Post-Event] Codecamp Conference Cluj-Napoca - Nov 19, 2016

Last day I was invited to another Codecamp Conference, that took place in Cluj-Napoca. Like other Codecamp Conferences, the event was very big, with more than 1.000 participants and 70 sessions. There were 10 tracks in parallel, so it was pretty hard to decide at  what session you want to join.
It was great to join this conference and I hope that you discovered something new during the conference.
At this event I talked about Azure IoT Hub and how we can use it to connect devices from the field. I had a lot of demos using Raspberry PI 3 and Simplelink SensorTag. Most of the samples were written in C++ and Node.JS and people were impressed that even if we are using Microsoft technologies, we are not limited to C# and .NET. World and Microsoft are changing so fast. Just looking and Azure IoT Hub and new features that were launched and I'm pressed (Jobs, Methods, Device Twin).
On backend my demos covered Stream Analytics, Event Hub, Azure Object Storage and DocumentDB.
