Synopsis

Documentation

spec :: Spec Source #

genInitTxMutation :: TxIn -> Tx -> Gen (Mutation, String, NotAnInitReason) Source #

genCommitTxMutation :: UTxO -> Tx -> Gen Mutation Source #

Properties

prop_observeAnyTx :: Property Source #

Given any Head protocol state and the transaction corresponding a protocol transition we should be able to observe this transition correctly even in presence of other valid Hydra Head protocol states in the used lookup utxo.

prop_splitUTxO :: UTxO -> Property Source #

Given a UTxO with more than one entry, we can split it into two non-empty UTxO.

propBelowSizeLimit :: Natural -> ((UTxO -> Tx -> Property) -> Property) -> SpecWith () Source #

propIsValid :: ((UTxO -> Tx -> Property) -> Property) -> SpecWith () Source #
