* add new option to the commandline option parser
* pass this as std::optional to the test-suite constructor
* use this value optionally to inject a fixed value on re-seeding
* provide diagnostic output to show the actual seed value used
...these features are now used quite regularly,
and so a dedicated documentation test seems indicated.
Actually my intention is to add a tracking allocator to these test helpers
(and then to use that to verify the custom allocator usage of `lib::Several`)
verify also that clean-up happens in case of exceptions thrown;
as an aside, add Macro to check for ''any'' exception and match
on something in the message (as opposed to just a Lumiera Exception)
Yesterday I decided to include some facilities I have written in 2022
for the Yoshimi-Testsuite. The intention is to use these as-is, and just
to adapt them stylistically to the Lumiera code base.
However — at least some basic documentation in the form of
very basic unit-tests can be considered »acceptance criteria«
Testcase (detect function invocation) passes now as expected
Some Library / Framework changes
- rename event-log-test.cpp
- allow the ExpectString also to work with concatenated expectation strings
Remark: there was a warning in the comment in event-log.hpp,
pointing out that negative assertions are shallow.
However, after the rework in 9/2018 (commit: d923138d1)
...this should no longer be true, since we perform proper backtracking,
leading to an exhaustive search.
without that check, in theory our test runner will tolerate
a non-zero return value, like throwing or failing an assert,
which is not what we want....
guess these happenend to get in by forgetting to
add this check when switching a test from PLANNED to TEST
over time, we got quite a jungle with all those
shome-me-the-type-of helper functions.
Reduced and unified all those into
- typeString : a human readable, slightly simplified full type
- typeSymbol : a single word identifier, extracted lexically from the type
note: this changeset causes a lot of tests to break,
since we're using unmangeled type-IDs pretty much everywhere now.
Beore fixing those, I'll have to implement a better simplification
scheme for the "human readable" type names....
so this turned out to be rather expensive,
while actually not difficult to implement.
On the way, I've learned
- how to build a backtracking matcher, based on
a filtering (monadic) structure and chained lambdas
- learned the hard way how (not) to return a container
by move-reference
- made first contact with the regular expressions
now available from the standard library
Heureka! found out that the C++ standard library exposes a
cross vendor C++ ABI, which amongst others allows to show
object code names and type-IDs in the language-level, human
readable unmangeld form.
Of course, actual application code should not rely on such a
internal representation, yet it is of tremendous help when
writing and debugging unit tests.

- the tests covering threadind support and object monitors
are located in the backend test-library and linked against liblumierabackend.so
- some fundamental facilities of proc-layer moved from the library tree
into the basic components tree, since *testing* them requires at least
to link against liblumieracommon.so
