用于创建类和接口的Visual Studio模板或代码段

Question

I am writing some Unit Tests and would like to create a Template/Code Snippet (Not sure what the exact terminology is in Visual studio). In simple terms i would like to create some boiler plate code which I can re-use.

ie, User will enter a Name of the class and use it to create a Interface, classes and some method definitions.

eg, If a user enters VATRate

IVATRate will be created in xyz.Common.Interfaces

VATRateRepository will be created in xyz.BusinessLayer

VATRateRepositoryTests will be created in xyz.BusinessLayer.Tests

Methods in VATRateREpositoryTests will be defined InsertVATRate_ShouldInsertNewRecord_WhenVatRateDoesNotExist UpsertVATRate_ShouldUpdateRecord_WhenRecordExist GetAllVATRate_ReadsAllRecords

etc..

You can automate it with my Visual Commander extension. The code for a command in C# will look like this:

References: Microsoft.VisualBasic

using EnvDTE;
using EnvDTE80;
using Microsoft.VisualBasic;

public class C : VisualCommanderExt.ICommand
{
    public void Run(EnvDTE80.DTE2 DTE, Microsoft.VisualStudio.Shell.Package package) 
    {
        string className = Microsoft.VisualBasic.Interaction.InputBox("Class name", "Create tests",
                    "VATRate", -1, -1);
        EnvDTE.ProjectItem f = DTE.ItemOperations.AddNewItem("Visual C# Items\\Code\\Class", className + "RepositoryTests.cs");
        EnvDTE.CodeClass c = FirstClass(FirstNamespace(f.FileCodeModel.CodeElements).Children);
        c.AddFunction("Insert" + className, vsCMFunction.vsCMFunctionFunction, vsCMTypeRef.vsCMTypeRefVoid);
    }

    private EnvDTE.CodeNamespace FirstNamespace(EnvDTE.CodeElements elements)
    {
        foreach(EnvDTE.CodeElement c in elements)
        {
            if(c is EnvDTE.CodeNamespace)
            return c as EnvDTE.CodeNamespace;
        }
        return null;
    }

    private EnvDTE.CodeClass FirstClass(EnvDTE.CodeElements elements)
    {
        foreach (EnvDTE.CodeElement c in elements)
        {
            if (c is EnvDTE.CodeClass)
                return c as EnvDTE.CodeClass;
        }
        return null;
    }
}

If you select a project in your solution and run the command from the VCmd menu, it will create the following file:
