Follow installation + build instructions in the primary README. Then, run:
yarn build:integrationCreate an .env file and fill it out.
Look at .env.example to know which variables to include.
Once you have your environment set up, run:
yarn test:integration:liveYou can also set environment variables on the command line instead of inside .env if you want:
L1_URL=whatever L2_URL=whatever yarn test:integration:liveNote that this can take an extremely long time (~1hr).
