Does this happen on every test case? Should better describe what is going on, e.g. " The following output can bee seen when the test is executed: test_flush_context (tpm2_tests.SpaceTest) ... \ /usr/lib64/python3.6/unittest/case.py:605: ResourceWarning: \ unclosed file <_io.FileIO name='/dev/tpmrm0' mode='rb+' closefd=True> An instance of Client does not implicitly close /dev/tpm* handle, once it gets destroyed. Close the file handle in the class destructor Client.__del__().
