We need to load a fixture with the following command:
./bin/load-fixtures.sh bafyreif3tfdpr5n4jdrbielmcapwvbpcthepfkwq2vwonmlhirbjmotedi
then, we can do npm run test:node -- -g 'lookup via HTTP Gateway'
to run a test that will tell us of any subsequent fixtures we need to load, and replace the CID in the above command with the CID that the test hangs on, and repeat.
