TPM 2.0 client library

Tests

This library contains unit tests in github.com/google/go-tpm/tpm2, which just tests that various encoding and error checking functions work correctly. It also contains more comprehensive integration tests in github.com/google/go-tpm/tpm2/test, which run actual commands on a TPM.

By default, these integration tests are run against the go-tpm-tools simulator, which is baesed on the Microsoft Reference TPM2 code. To run both the unit and integration tests, run (in this directory)

go test . ./test

These integration tests can also be run against a real TPM device. This is slightly more complex as the tests often need to be built as a normal user and then executed as root. For example,

# Build the test binary without running it
go test -c github.com/google/go-tpm/tpm2/test
# Execute the test binary as root
sudo ./test.test --tpm-path=/dev/tpmrm0

On Linux, The --tpm-path causes the integration tests to be run against a real TPM located at that path (usually /dev/tpmrm0 or /dev/tpm0). On Windows, the story is similar, execept that the --use-tbs flag is used instead.

Tip: if your TPM host is remote and you don't want to install Go on it, this same two-step process can be used. The test binary can be copied to a remote host and run without extra installation (as the test binary has very few runtime dependancies).
