First Ever Contribution - Solves issue#17

[bosesubham2011]

Hey Community,

As this is my first contribution ever, I wanted to start with writing pester test cases.
I will schedule my time to write test cases everyday for the code that is maintained here.

I need the following from the community to help build effective and advanced test cases:

1. How the Syntax of each command looks like? [ Get-Command -Syntax {Command-Name}]
2. If a sample of returned objects of each of the commands can be sent to me by exporting them in clixml
   [ $object = Get-DomainComputer
   $object| Export-CliXML ""]

I will be able to learn and share all cool new things with pester and can write unit tests for each of the modules (in-depth).
