requires to supplement EventLog matching primitives
to pick and verify a specific positional argument.
Moreover, it is more or less arbitrary which job invocation parameters
are unpacked and exposed for verification; we'll have to see what is
actually required for writing tests...
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.
seemingly my quick-n-dirty implementation was to naiive.
We need real backtracking, if we want to support switches
in the search direction (match("y").after("x").before("z")
Up to now, I have cheated myself around this obvious problem :-/
this bit of Sed magic relies on the fact that we happen to write
the almost correct class name of a test into the header comment.
HOWTO:
for F in $(find tests -type f \( -name '*.cpp' \) -exec egrep -q '§§TODO§§' {} \; -print);
do sed -r -i -e'
2 {h;x;s/\s+(.+)\(Test\).*$/\\ref \1_test/;x};
/§§TODO§§/ {s/§§TODO§§//;G;s/\n//}'
$F;
done
Doxygen will only process files with a @file documentation comment.
Up to now, none of our test code has such a comment, preventing the
cross-links to unit tests from working.
This is unfortunate, since unit tests, and even the code comments there,
can be considered as the most useful form of technical documentation.
Thus I'll start an initiative to fill in those missing comments automatically
reason is, only files with a @file comment will be processed
with further documentation commands. For this reason, our Doxygen
documentation is lacking a lot of entries.
HOWTO:
find src -type f \( -name '*.cpp' -or -name '*.hpp' \) -not -exec egrep -q '\*.+@file' {} \; -print -exec sed -i -r -e'\_\*/_,$ { 1,+0 a\
\

/** @file §§§\
** TODO §§§\
*/
}' {} \;
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....
- remove unnecessary includes
- expunge all remaining usages of boost::format
- able to leave out the expliti string(elm) in output
- drop various operator<<, since we're now picking up
custom string conversions automatically
- delete diagnostics headers, which are now largely superfluous
- use newer helper functions occasionally
I didn't blindly change any usage of <iostream> though;
sometimes, just using the output streams right away
seems adequate.
...this is necessary whenever the mocked facility covered
by log matching is managed automatically as singleton,
because then other test cases will leave garbage
in the log
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
abandon the use of an assertion exception to signal match failure,
rather use a final bool conversion to retrieve the results.
Error messages are now delivered by side effect into STDERR
The reason is we're unable to deliver the desisred behaviour
with the chosen DSL syntax in C++ ; on a second thought the
new approach is even better aligned with the overall way
we're writing tests in Lumiera. And we produce match-trace
messages to indicate the complete matching path now
...no need to enclose empty sections when there are no
attributes or no children. Makes test code way more readable.
TestEventLog_test PASS as far as implemented
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
right now we have to defeat an unfortunate static assertion in
the standard library, which is expected to go away in the future.
We use a hack to hijack the problematic definition with the preprocessor,
which requires our header to be first.
to make them stand out more prominently, some entity comments
where started with a line of starts. Unfortunately, doxygen
(and javadoc) only recogise comments which are started exactly
with /**
This caused quite some comments to be ignored by doxygen.
Credits to Hendrik Boom for spotting this problem!
A workaround is to end the line of stars with *//**
the buildsystem will now pick up and link
all test cases according to the layer, e.g.
backend tests will automatically be linked
against the backend + library solely.
