    The testing can be done at PCB design level after using various design analysis techniques like EMI, Signal Integrity and Power Integrity ,the design issues can be minimized

Although I am NOT a test engineer, it's always great to learn how the board design will fair during DUT, DFM

A (PCB) test jig can be identified as a device or machinery that holds a piece of machine work which now a days comprised of much electronic intelligence and guides the tools operating on it. 

It should not be confused with Test fixtures which are used to keep the object firmly in place

(2) Assembly Level Tests 
After the board has been properly assembled it may be tested in a variety of ways using either manual inspection or using expensive Automatic test equipment (ATE).Automatic test equipment enables PCB test, and equipment test to be undertaken very swiftly. Automatic test equipment is quite expensive, and therefore it is necessary to select the proper type suitable for the application and board to be tested. 
(3) Function tests 
Functional test (FCT) is used as a final manufacturing step. It provides a pass/fail determination on finished PCBs before they are shipped. An FCT’s purpose in manufacturing is to validate that product hardware is free of defects that could, otherwise, adversely affect the product’s correct functioning in a system application.
In short, FCT verifies a PCB’s functionality and its behavior. It is important to emphasize that the requirements of a functional test, its development, and procedures vary widely from PCB to PCB and system to system.Functional testers typically interface to the PCB under test via its edge connector or a test-probe point. This testing simulates the final electrical environment in which the PCB will be used.The most common form of functional test, known as “hot mock-up” simply verifies that the PCB is functioning properly. More sophisticated functional tests involve cycling the PCB through an exhaustive range of operational tests.
