Migrating from MSTest to NUnit

I am using VS2015 and VS2017 and I needed to migrate from Microsoft Unit tests to NUnit.

Those are the steps are followed.

  • In VS2015/2017 Select the “Package manager console” tab
    Select the correct project, (drop down combo), and type
 install-package nunit
  • Or using Nuget manager
    • Select the correct project.
    • Select NUnit, (just the plain ‘NUnit’ for now).
  • In your test project, look for “using Microsoft.VisualStudio.TestTools.UnitTesting;
    Replace with “using NUnit.Framework;“, (of course you will now have a whole bunch of errors.)
  • Look and replace
    • [TestClass] replace with [TestFixture]
    • [TestMethod] replace with [Test]
    • Remove code that looks like “[ExpectedException(typeof(xyz), “some text”)]” and surround the actual code that is expected to throw
Assert.Throws<xyz>(() => { BadCode(); });

NB: Note you might need to change a couple of other values

  • [TestInitialize] to [SetUp]
  • [TestCleanup] to [TearDown]
  • [TestClassInitialize] to [TestFixtureSetUp]
  • [TestClassCleanup] to [TestFixtureTearDown]

And a few other functions will need to change as well but for the most part they start with Assert.... and are fairly close(tm) to the Microsoft counterparts.


Deleting folders that refuse to be deleted…

Sometimes when you want to delete a folder in windows you get a very useful message “Could not find this item… this is no longer located in …”, (yes, the very item you just tried to delete).

So after a bit of cursing, making sure that you are indeed the admin of this box, praying to the windows gods you realise that maybe Windows Explorer is at fault.

Not to worry you think, you open up a cmd line console and navigate to the parent of the offending folder.

And like a true hacker you type

“rd c:\my\bad\folder”

only to be told once again, “The system cannot find the file specified.”

At this point your realise that the folder has spaces… so you think “no problem, I will quote the folder” and you now type

‘rd “c:\my\bad\folder “‘

with the correct number of spaces in the folder name.

Long story short… you cannot do that.

You cannot rename the folder, (I know you will try anyway, but you can’t)

So you Googled for a solution and here you are…

what you need to do is tell the command line to not trim the folder name and to do that, you have to add “\?\” in front, so now you type

‘rd /s /q “\\?\c:\my\bad\folder “‘

Complete with the extra spaces and so on… (I added the /s and /q flags because you forgot that the directory is not empty)

vs2015/2013 – Cannot see unit tests in Test Explorer window

If have some unitests in Visual Studio 2015 or 2013 but you cannot see them in your “Test Explorer window”

If you look in your output window, (under “Show output from:” > “test)

An exception was thrown while initializing part “Microsoft.VisualStudio.TestWindow.UI.TestWindowToolWindowControl”.

The solution is just to delete the VS2013/VS2015 cache folder, located either in


For VS2013, or


For VS2015

Git and submodule

Sometimes things get a little out of sync in your submodule folder, your ‘root’ project sometimes report something like

\ In the git branch
[branch = +0 ~1 -0 !]>

Or even  something along the lines of

\ In the submodule folder

Showing that you are no longer on the correct branch, (for the submodule).

One one way to clean it all up is to do.

\ In the submodule folder
git checkout master
git pull
git push origin HEAD:master
git checkout master

Assuming that you have no other changes to commit

\ In the root folder
git clean -fd
git pull
git submodule update --init --recursive
git submodule update

And that should clear everything

Using Github from command line

This assumes that you have all the permissions needed to access your repo, (passwords and so on).

Start Git Shell and navigate to your local repo.

Create a branch

git checkout -b <branch-name>
git push <remote-name> <branch-name>

In the case of github the remote name is ‘origin’


Add your changes to the branch

git add .

The ‘.’ means ‘everything’ that was changed.

You can use ‘status’ to check what needs to be staged, (or what has been staged).

git status

Commit branch

git commit -m "You message here"

Push branch
The first time you need to tell where you are pushing this to.

git push --set-upstream <remote-name> <branch-name>

The afterwards you just need to do…

git push

Delete your branch

To remotely delete it

git push <remote-name> --delete <branch-name>

To locally delete it

git branch --delete <branch-name>
