Arguments

:: [NonEmpty RelayAccessPoint]	each inner list denotes relays of one pool. PRECONDITION: each inner list must be non-empty.
-> Gen LedgerPools

prop_ledgerPeerSnapshot_requests :: ArbStakeMapOverSource -> Property Source #

This test checks whether requesting ledger peers works as intended when snapshot data is available. For each request, peers must be returned from the right source - either the ledger or snapshot, depending on whether which source is fresher.

prop_pick100 Source #

Arguments

:: Word16
-> NonNegative Int	number of pools with 0 stake
-> ArbLedgerPeersKind
-> MockRoots
-> DelayAndTimeoutScripts
-> ArbitrarySlotNo
-> Property

A pool with 100% stake should always be picked.

prop_pick :: LedgerPools -> ArbLedgerPeersKind -> Word16 -> Word16 -> MockRoots -> Script DNSLookupDelay -> ArbitrarySlotNo -> Property Source #

Verify that given at least one peer we manage to pick count peers.

prop_accumulateBigLedgerStake :: LedgerPools -> Property Source #

prop_recomputeRelativeStake :: LedgerPools -> Property Source #

This functions checks the following properties: 1. The accumulated relative stake adds up to unity 2. No pool relative stake can be less than 0 3. The relays aren't mangled 4. Running this function multiple times always produces the same result

prop_getLedgerPeers :: ArbitrarySlotNo -> LedgerPools -> ArbitrarySlotNo -> Property Source #

prop_ledgerPeerSnapshotCBORV2 :: ArbitrarySlotNo -> LedgerPools -> Property Source #

Checks validity of LedgerPeerSnapshot CBOR encoding, and whether round trip cycle is the identity function

prop_ledgerPeerSnapshotJSONV2 :: ArbitrarySlotNo -> LedgerPools -> Property Source #

Tests if LedgerPeerSnapshot JSON round trip is the identity function

snapshotV2 :: ArbitrarySlotNo -> LedgerPools -> LedgerPeerSnapshot Source #

helper functions for ledgerpeersnapshot encoding tests
