I suppose this test should be added similarly to "src/tests/test.cpp".

[engedy, 2017/03/09 14:53:14]

Right. Note, however, that each of these exports a main() function, so it will
need to go into another test target (it looks like we missing a few targets,
actually).

I'd suggest filing a bug on it, and fixing this in a follow-up CL  so that we
can unblock the dependent CL.

[pkalinnikov, 2017/03/09 17:36:58]

Filed crbug.com/700039 for this and the one below.

+    #  - tests/fuzzer/flatbuffers_verifier_fuzzer.cc
+    #  - tests/fuzzer/flatbuffers_parser_fuzzer.cc

[pkalinnikov, 2017/03/09 13:03:17]

These 2 fuzzer tests are not included into CMakeLists.txt, but have scripts to
run them. Do we need to test it somehow with our infrastructure?

[engedy, 2017/03/09 14:53:14]

I believe this is exercised by ClusterFuzz outside of Chromium continuous build.
Looks like this has file been upstreamed from here:

https://cs.chromium.org/chromium/src/testing/libfuzzer/fuzzers/flatbuffers_ve...

Would also file a bug and figure out what to do about this later.

[pkalinnikov, 2017/03/09 17:36:58]

Done.

+    #  - tests/monster_test.grpc.fb.cc

[pkalinnikov, 2017/03/09 13:03:17]

This one is probably not a test. Will delete it.

[pkalinnikov, 2017/03/09 17:36:58]

Done.
