On the long run, yes. I just added this section, to start the page. And
since it's just STARTing... this was in the first or second reaction
that came in. Feel free to edit ('go wild' ;-))!

I wouldn't bother to have several pages like this one will be (it's
supposed to be an index on the long run), each covering another way of
testing.

I just meant to take _ACT_. Scepticism is a good thing, as long as it
doesn't stop you from doing.

We do test our software by using it. But the bug in the HTML-exporter
that Carsten has fixed two days ago, was introduced in early September
and would be in 6.10, which is supposed to be in the emacs 23 release.

A very simple test plan would have revealed it.

Why? If the test bails out 'ERROR', I will have to look for the
reason. If the format changed in a legal way => adjust the test.

Yes, because Carsten add features en masse :-)
I see the testing differently. In the first place we need THINK of
testing.

New Org-revision out?
Ahh, OK, I have to the HTML-exports, I want to be working.

To do this, I need several different setups, several different data
directories (Org-files) and an easy way to test, that doesn't eat my
time and gives a result. The quality may vary, but ERRORs will be
detected for shure.

Not one or mounths later - immediately.

If someone installs emacs 23, tries to export to HTML and gets an
error....

Yes, but we can do better, easier and more complete.
