What are we doing ?
We are trying to create a snippet for creating an NUnit test.
How do we do this ?
We go write a snippet.
The snippet is here NUnit Snippet
Save it under ..\Documents\Visual Studio 2012\Code Snippets\Visual C#\My Code Snippets
Now go add the snippet.
Go to Tools in VS -> Code Snippets Manager -> and Import after clicking on the Snippet.
That’s it, we are done.
