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 §§§\
*/
}' {} \;
...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
