Module respondToOpenOutputFiles / respondToCloseOutputFiles not being called.
ProductMix_r1c2, we get the output:
/home/greenc/work/cet-is/build/mrb-debug/srcs/art/art/test/Integration/MixFilterTestETS_module.cc(327): error: in "art_ut/art_ut": check respondFunctionsSeen_ == 4ul has failed [2 != 4] *** 1 failure is detected in the test module "Master Test Suite"
Note this does not actually fail the test because the presence of the
PASS_REGULAR_EXPRESSION property of the CMake test overrides the non-zero exit code of the test program. This will be the subject of a separate bug report.
Investigation reveals that for reasons yet to be determined,
MixFilterTestETS::respondToOpenOutputFiles() are not being called.
This problem may additionally occur in other tests.
