Install penumbra and CometMock. Make sure cometmock is compiled from branch v0.34.x. My penumbra version is from branch 2771-cometmock-smoketest.
Run cometmock-test.sh
This will print out two commands, one for penumbra and one for CometMock.
Just copy-paste the commands and run them (in separate terminals). Run pd first, give it a second until it's started,
then run the one for CometMock.
They look like this for me:
cargo run --quiet --release --bin pd -- start --home /Users/offtermatt/.penumbra/testnet_data/node0/pd
for pd
