Hey, I'm currently looking into projects that have low coverage in oss-fuzz. (You can find an overview of this project here: https://introspector.oss-fuzz.com/project-profile?project=tpm2-tss.)

This project seems to have close to zero covered lines. Running some fuzz targets manually it seems that there is just a configuration/environment error:

ERROR:test:test/integration/test-common.c:320:test_sys_setup() TCTI module not specified. Use environment variable: TPM20TEST_TCTI

example coverage report

I tried a little bit to fix this by setting: TPM20TEST_TCTI=libtpms but it seems I'm failing to install libpms correctly, which is probably just my missing familiarity with this project.

I'm happy to help but before spending more time I wanted to ask: Is this issue already known and should it be fixed? If yes, how would you want to approach the fix?
