ftest coverage functionality is broken

[fgalan]

Code coverage reporting feature implemented in makefile could be broken (and I don't know since when).

It seems that the coverage target for unit tests works (see this) but problems happens with the functional test pass:

$ make coverage_functional_test INSTALL_DIR=~
...
 11/1130 Test   #11: geoquery_circle_deprecated ............................................................***Failed  Error regular expression found in output. Regex=[[^a-z]Fail] 11.95 sec

If we run testHarness just after that (i.e. without rebuilding the contextBroker binary) we can see the same tests are failing:

$ ./testHarness.sh cases/0000_deprecated_checkings/legacy_geoquery_circle_json.test

Looking into CB traces in /tmp/contextBroker.log we see:

This is very weird... if we rebuild contextBroker binary again doing make di INSTALL_DIR=~ and run ./testHarness.sh cases/0000_deprecated_checkings/legacy_geoquery_circle_json.test again it works.

The cause could be in the following part:

prepare_coverage: compile_info
        mkdir -p  BUILD_COVERAGE || true
        cd BUILD_COVERAGE && cmake .. -DCMAKE_BUILD_TYPE=DEBUG -DBUILD_ARCH=$(BUILD_ARCH) -DUNIT_TEST=True -DCOVERAGE=True -DCMAKE_INSTALL_PREFIX=$(INSTALL_DIR)

The UNIT_TEST declaration could be problematic for the contextBroker binary (it is good for the unitTest binary). Look for the #ifdef UNIT_TEST and #ifndef UNIT_TEST in the code.

Maybe activating UNIT_TEST the logic that check geo-query capabilities in the code gets disabled and that's is causing the above problem (just a theory, needs to be checked).

[fgalan]

I have tried to disable the UNIT_TEST declaration this way:

        @echo '------------------------------- prepare_unit_test starts ---------------------------------'

But I get this error:

This needs to be debuged and tested. Maybe a first step in the solution is not to use the same prepare_coverage target for both contextBroker and unitTest binaries (maybe split it into prepare_coverage_unittest and prepare_coverage_ftests).

Re-writting the coverage related targets from scratch in the makefile file could be also a good idea.
