I have put my hands on that, and I found that the tests were a bit
overengineered. First, SimpleLruDoesPhysicalPageExist() is not that
much necessary before and after each operation, like truncation or
deletion, as the previous pages were doing equal tests. The hardcoded
page number lacks a bit of flexibility and readability IMO, especially
when combined with the number of pages per segments, as well.
I have reworked that as per the attached, that provides basically the
same coverage, going through a SQL interface for the whole thing.
Like all the other tests of its kind, this does not use a TAP test,
relying on a custom configuration file instead. This still needs some
polishing, but the basics are here.
What do you think?
