System Test: Operator

[nkuba]

Stake

• [x] Start client when operator account has just minimum stake

• [x] Start client when operator account has multiples of minimum stake

  • client starts successfully and is selected to new keep after open keep request

Insufficient stake

🚫 Blocked by https://github.com/keep-network/keep-core/issues/1588

---

• [ ] Start client when operator account has ZERO stake
• [ ] Start client when operator account has below minimum stake

Expected results:

• client starts and is monitoring the chain
• other peers nodes reject connection
• operator does not get selected to any new keep group
• it does not pick requests for a signature from the existing keep

---

• [ ] Drop stake below minimum while client is running Expected results:

  • client updates it's status in sortition pool
  • other peers nodes reject connection
  • operator does not get selected to any new keep group
  • it does not pick requests for a signature from the existing keep

• [ ] Drop stake below minimum and restart the client

  After start get into some keeps to generate the key, later unstake and restart the client.

  Expected results:

  • client starts and is monitoring the chain
  • other peers nodes reject connection
  • operator does not get selected to any new keep group
  • it does not pick requests for a signature from the existing keep

Ether

---

• [x] Start client when operator account has some ETH
• [x] Drop ETH for operator account while client is running
• [x] Drop ETH for operator account and restart the client

---

Expected results:

• client starts and is monitoring the chain
• client establishes a connection with peer nodes
• operator gets selected to a new keep group
• operator takes part in signature generation for keeps

---

• [x] Start client when operator account has ZERO ETH and open new keep

  Ensure the operator is selected to the keep.

  • client starts and is monitoring the chain
  • client establishes a connection with peer nodes
  • operator gets selected to a new keep group but fails on key submission
  • it is not possible to request a signature as public key has not been published
  • other keep members succeed to generate the public key

---

• [x] Start client when operator account has ZERO ETH and request a signature

  • client starts and is monitoring the chain
  • client establishes a connection with peer nodes
  • operator calculates the signature but fails to publish it to the chain
  • other keep members succeed to calculate the signature and one of them publishes the signature to the chain

---

• [x] Monitor ETH usage for opening new keep and generating a signature

Bond

• [x] Start client when operator account has ZERO unbonded value

  • client starts and is monitoring the chain
  • client establishes a connection with peer nodes

• [x] Start client when operator account has 1 ETH of unbonded value

  • client starts and is monitoring the chain
  • client establishes a connection with peer nodes

• [x] Request new keep when operator's unbonded value is ZERO

  • operator is not selected to the keep

• [ ] Request new keep when operator's unbonded value is positive but less than requested bond / group size

  • operator is not selected to the keep

• [ ] Request new keep when operator's unbonded value is equal to requested bond / group size

  • operator is selected to the keep

• [ ] Request new keep when operator's unbonded value is greater than requested bond / group size

  • operator is selected to the keep

• [ ] Request a signature for existing keep when operators unbonded value is ZERO

  • Signature is successfully calculated and submitted

--

• [ ] Drop unbonded value to ZERO while client is running

• [ ] Drop unbonded value to ZERO and restart the client --

• client is working and is monitoring the chain

• client updates operator's status in the factory contract

• client establishes a connection with peer nodes

• operator does not get selected to a new keep

• operator takes part in signature generation for existing keeps

Operator Contract Authorization

• [ ] Start client without BondedECDSAKeepFactory authorization in TokenStaking contract

  • client is working and is monitoring the chain
  • client establishes a connection with peer nodes
  • operator does not get selected to a new keep

• [x] Authorize BondedECDSAKeepFactory in TokenStaking contract for operator

  • client is working and is monitoring the chain
  • client establishes a connection with peer nodes
  • operator gets selected to a new keep

Sortition Pool Authorization

• [x] Start client when sortition pool is not yet created

  • client starts and is monitoring the chain
  • client establishes a connection with peer nodes
  • operator is not selected to a new keep

• [x] Start client without sortition pool authorization in KeepBonding contract

  • client starts and is monitoring the chain
  • client establishes a connection with peer nodes
  • operator is not selected to a new keep

• [x] Authorize sortition pool in KeepBonding contract for operator

  • client is working and is monitoring the chain
  • client establishes a connection with peer nodes
  • operator gets selected to a new keep

Stake Initialization Period

Execute these tests in a setup where group size is the same as number of running nodes.

• [x] Start client just after delegating a stake to the operator, so stake initialization period has not passed yet.

  • client starts and is monitoring the chain
  • client establishes a connection with peer nodes
  • operator is not selected to a new keep
  • open keep fails

• [x] Request new keep after stake initialization period (10 blocks) has passed

  • operator is selected to a new keep
