DFT affects and depends on the methods used for test development, test application, and diagnostics. Most tool-supported DFT practiced in the industry today, at least for digital circuits, is predicated on a Structural test paradigm. Structural test makes no direct attempt to determine if the overall functionality of the circuit is correct.
Test compression is a technique used to reduce the time and cost of testing integrated circuits.The first ICs were tested with test vectors created by hand. It proved very difficult to get good coverage of potential faults, so Design for testability (DFT) based on scan and automatic test pattern generation (ATPG) were developed to explicitly test each gate and path in a design.

Defining what manufacturing test process is needed based from the product definition. Verifying that the currently available test equipment is adequate for testing the proposed design. If new equipment is needed, budgetary concerns have been addressed and sufficient lead time exists for new equipment installation and verification.

A fault coverage test passes when at least a specified percentage of all possible faults can be detected. If it does not pass, at least three options are possible. First, the designer can augment or otherwise improve the vector set, perhaps by using a more effective automatic test pattern generation tool. Second, the circuit may be re-defined ...
A useful property of the DFT is that the inverse DFT can be easily expressed in terms of the (forward) DFT, via several well-known "tricks". (For example, in computations, it is often convenient to only implement a fast Fourier transform corresponding to one transform direction and then to get the other transform direction from the first.)
