NewLedger creates new ledger instance.

func NewTestLedger

func NewTestLedger(
	db *storage.DB,
	am *artifactmanager.LedgerArtifactManager,
	pm *pulsemanager.PulseManager,
	jc *jetcoordinator.JetCoordinator,
	amh *artifactmanager.MessageHandler,
) *Ledger

NewTestLedger is the util function for creation of Ledger with provided private members (suitable for tests).
