I dont see Using Test-Point Callbacks for Automated Diagnostics in Testing as being any more efficient than a print statement since multiple arguments of lexicals are still evaluated and copied if the branch is taken and those instructions will not be removed, although they wont execute, with debugging mode off. The only advantage I see of Using Test-Point Callbacks for Automated Diagnostics in Testing is that errors can be discovered automatically with code, rather than the programmer looking for a needle in a haystack wrong value in a mile of debug channel.

    Exactly! That is precisely the idea: to give a more intelligible diagnostic message instead of having to go through millions of debug messages.

    Whilst the general consensus that the smallest testable unit is a sub, in many real world applications this is simply not the case. A lot of business code has a lot of state data shared in long subroutines. They are always room for refactoring but in the mean time, you need to provide mechanisms to test this code the best you can.
