Test connectivity via a specific network interface

Recently while working on a Private cloud implementation, I came across a scenario where I needed to test connectivity of a node to the AD/DNS via multiple network adapters. 

Many of us would know that having multiple network routes is usually done to take care of redundancy. So that if a network adapter goes down, one can use the other network interface to reach out to the node.

In order to make it easy for everyone to follow along, below is an analogy for the above scenario:

My laptop has multiple network adapters (say Wi-Fi and Ethernet) connected to the same network. Now how do I test connectivity to a Server on the network only over say Wi-Fi network adapter?
