I am trying to create test case in C# for the WDF drivers of Smartcard devices. but i could not find the Windows driver > Windows Driver Test template under installed Visual C#. I am using the Visual Studio 2013 for Windows Desktop. i could not even find the Windows Driver Test in online template. Any other package i need to install?
You might be running into problems because of the version of Visual Studio that you're running: VS 2013 for Windows Desktop is essentially an "Express" edition of VS put together to provide developers with a basic IDE for building Windows desktop apps for free. The Express SKU's of VS were, however, limited in their functionality and do not support add-ons and additional SDK's, project templates and/or tooling such as WDK. For that you'll likely need a Pro edition of VS.
Note: Microsoft has recently released Visual Studio Community Edition which is a full release of VS Pro, including add-ons and extensibility, but free for non-commercial use and/or dev teams of up to 5 people. If you meet these licensing requirements, then you may have more luck using VS Community Release than VS for Windows Desktop.
