This document defines the end-to-end testing of the following Waku features, to be delivered as part of release 0.30.0:

• RLN v2: This introduces a “two-dimension” rate limiting, allowing to rate limit x messages every y seconds.
• Onchain Merkle trees: This allows light clients to be stateless, using the contract as a source of Merkle proofs, used to create RLN proofs for messages. No need to sync the Merkle tree as before.

Test Environment

The following tests shall be performed using waku-simulator. See instructions.

Use Cases

• UC1 The network accepts valid messages published via full nodes using the REST API.
  • Repeat for different values of rln-relay-epoch-sec and rln-relay-user-message-limit.
  • Repeat for different message rates and sizes.
  • Repeat for different nodes publishing. Just one, a few, all.
• UC2 The network rejects messages from spammer nodes and at some point disconnects from them.
  • Repeat for different values of rln-relay-epoch-sec and rln-relay-user-message-limit.
  • Repeat for different spam rates.
  • Repeat with multiple spammer nodes. One, many.
• UC3 A light client publishes messages using a given full node as lightpush, and messages are correctly routed in the network.
  • Repeat with different light client instances. One, many.
  • Repeat for different values of rln-relay-epoch-sec and rln-relay-user-message-limit.
  • Repeat for different message sizes.
  • Repeat with multiple nodes being used as lightpush.
• UC4 Messages remain valid when multiple memberships are being inserted into the contact.
  • Perform all/some of the previous tests while constantly inserting memberships into the contract. Ensure that the results does not change.
• UC5 Fuzzing
  • Introduce messages with unexpected values and behaviours

Test Setup

The images that will be used for testing are:

• harbor.status.im/wakuorg/nwaku:v0.30.0-rc.2 shall be used for nominal testing.
• quay.io/wakuorg/nwaku-pr:2821 shall be used for full node spammer testing.
• alrevuelta/go-waku-light:4fabb22 shall be used for light client testing

All tests will use these environment variables for the RLNv2 contract deployment:
