I hope you don't mind if I reply only to the points I think are most
important - the mail would grow to unmanageable dimensions if I
replied to everything, and the other readers would get bored.

Quoting Robert Klemme (shortcutter@googlemail.com):

> Well, yes.  But since you do test you obviously think that is a good

I obviously do think it is good to shake my code a lot so that the
flaky points manifest themselves. And I developed a good sense for how
they manifest. Nothing that could be codified/automatized, I am
afraid.

Adopting impossible goals is very romantic. sometimes it is
impractical, but of course you are free to adopt any goal you
want. The problem arises when people think that, by adopting that
specific goal, they will actually obtain bug-free code. 

> But, as you say,

"works always" and "has zero bugs" are equivalent statements. What I
state is that any non-trivial software package can be rendered
*virtually* bug-free by maintaining it long enough without changing it
too much. By that time, it will have become brittle (either unsuitable
to the hardware or unsuitable to the task, and very hard to change).

I further state that anybody who guarantees that a non-trivial new
software being delivered to the public will "work always" (or "has
zero bugs") is a shameless liar. There is no way you can guarantee
that.

Software has to be gently led through its first steps, and then
affectionately helped in growing and adapting to new needs. A software
package is a living creature, not a commodity.

Here is the point. It is a false confidence. You may have made errors
in the tests, for example. You'd need tests for your tests,
etc. etc. 

Or it may even be that you will face a situation that the creator of
the automated test system you use did not think about.

Have you read Douglas Hofstadter's book about Gel, Escher & Bach?
It has been one of the most important books I read in my formative
years...

It's the typical thing that cannot be imposed. Good luck,
management...
