The tests in src/vppinfra are lightly used - primarily by me - but yes, we do use them from time to time.
test-gcov has worked as expected - at least on x86_64 - since we merged https://gerrit.fd.io/r/#/c/19379/. Running gcov manually is possible, but frankly it's not recommended. If you insist: * Either "make test-gcov" or run a "PLATFORM=vpp TAG=vpp_gcov" image. * For each file which managed to execute code, you should find a ".gcda" file. * To manufacture a .gcov file, "gcov xxx.gcda". * Look at the [set of] foo.c.gcov files in your favorite text editor. You'd be much better off running "lcov," which produces nice html reports and [importantly] understands multi-architecture executables. See attached scripts. $ cd <workspace-root> $ lcov_prep $ make test-gcov $ lcov_post Nice html output in build-root/html, point a browser at build-root/html/index.html HTH...

I see these files in test_xxx (e.g. test_mheap, test_fifo). Are these test programs still maintained ? If so, how are they invoked/run ? If I am correct Functional tests invoked from "make test" invoke the Python Functional test framework in (test/*) which seems more Traffic based Functional tests rather than unit tests. 2. What is the status on test-gcov ? As in is it still maintained. I tried running make test-gcov with subset of test to see the code coverage of the tests but failed to find any .gcov file getting generated. Do I have to do anything else ? Thank you Sirshak Das
