To run the test suite you will have to provide it with a set of private keys for the node. The private key needs to be registered with the blockchain smart contract and a NodeID has to be issued. For more info see Onboarding
Create a file in the top level directory called secrets.yaml and set your node private keys such as:
env.secret.XMTPD_SIGNER_PRIVATE_KEY: "<key>"
env.secret.XMTPD_PAYER_PRIVATE_KEY: "<key>"
