Switch integration tests to OffchainLabs/arbitrum-testnode action#629
Merged
Conversation
Replace OffchainLabs/actions/run-nitro-test-node with the new snapshot-backed OffchainLabs/arbitrum-testnode action. Uses pre-built Docker images instead of building from source, cutting testnode startup from ~20min to ~30sec. - fee-token-decimals input replaces --l3-fee-token args - Network config exported via env var instead of docker exec
Replace polling-based waitUntilReadyToExecute (500ms interval, 5-7 RPC calls per poll) with a test utility that listens for NodeConfirmed / AssertionConfirmed events and resolves immediately. Also reduce mineUntilStop interval from 15s to 1s.
Use the migrated action (l3-node -> l3-enabled input rename) and the nc-format fast snapshot image dl-ci-fast-2 from the arbitrum-testnode-ci package.
