  I did not feel my question was disingenious or silly, as I *really* did
not know why* anyone even bothers with testing frameworks.  While Alexey
provided *an* answer (well, four really), they didn't explain to me *why* a
framework is needed, as the four items he mentioned could be done without a
framework.  It is indeed, Adam's answer that provides, to me, some cases I
did not consider at all (like the randomized order case---question: does
*any* Lua testing framework provide *that* functionality?) [1].

  Just because *you* know does not mean *everybody* knows.

  Or the person has never worked in an environment with centralized logging
for diagnosis or audits.

[1]	I was so intrigued with running the tests in a random order that I
	took five minutes to test that with our regression test at work
	(test written in Lua, testing a component written in Lua).  Glad to
	say the tests passed.

	And no, I do not use an existing test framework for this [2].

[2]	Even though I need to create 10,660 files before running the 7,776
	tests, and to run the 7,776 tests requires running four other
	programs (in addition to the program being tested and the test
	program---and of the four additional programs, three are mock
	versions of the real thing).

	To be fair, I have a program that generates the 10,660 files
	required for the test, and a separate program that runs everything,
	including the tests.  Yes, you can even run a single test if need
