Functions

func AlwaysSuccessfulCollatCheckFn 

func AlwaysSuccessfulCollatCheckFn(
	subaccountMatchedOrders map[satypes.SubaccountId][]clobtypes.PendingOpenOrder,
) (success bool, successPerUpdate map[satypes.SubaccountId]satypes.UpdateResult)

AlwaysSuccessfulCollatCheckFn is a collateralization check function that always returns success.

func CreateCollatCheckFunction 

func CreateCollatCheckFunction(
	t *testing.T,
	collateralCheckCounter *int,
	expectedCollatCheckParams map[int]map[satypes.SubaccountId][]clobtypes.PendingOpenOrder,
	collatCheckFailures map[int]map[satypes.SubaccountId]satypes.UpdateResult,
) (
	collatCheckFn clobtypes.AddOrderToOrderbookCollateralizationCheckFn,
)

CreateCollatCheckFunction creates a collateralization check function that can be used when calling the `PlaceOrder` function on the memclob. It asserts that the passed in parameters to the collateralization check function are correct, and returns the specified collateralization check results. Note that this function takes a pointer parameter representing the number of collateralization checks, and increments it after each performed collateralization check such that the caller can assert the expected number of collateralization checks are performed.

func CreateSimpleCollatCheckFunction 

func CreateSimpleCollatCheckFunction(
	t *testing.T,
	collateralCheckCounter *int,
	expectedCollatCheck map[int]CollateralizationCheck,
) (
	collatCheckFn clobtypes.AddOrderToOrderbookCollateralizationCheckFn,
)

CreateSimpleCollatCheckFunction creates a collateralization check function that can be used when calling the `PlaceOrder` function on the memclob. It asserts that the passed in parameters to the collateralization check function are correct, and returns the specified collateralization check results. Note that this function takes a pointer parameter representing the number of collateralization checks, and increments it after each performed collateralization check such that the caller can assert the expected number of collateralization checks are performed.

func HasMessage 

func HasMessage(
	offchainUpdates *types.OffchainUpdates,
	orderId types.OrderId,
	messageType types.OffchainUpdateMessageType,
) bool

HasMessage checks if OffchainUpdates contains an message for the given OrderId & OffchainUpdateMessageType. Useful for when we want to verify an update message was added for a specific scenario.

func MessageCountOfType 

func MessageCountOfType(
	offchainUpdates *types.OffchainUpdates,
	messageType types.OffchainUpdateMessageType,
) int

MessageCountOfType counts the number of messages in OffchainUpdates of a given type (Place/Remove/Update). Useful for when we want to verify we've added the correct number of messages.

func OrderSideHumanReadable 

func OrderSideHumanReadable(isBuy bool) string

OrderSideHumanReadable is a testing observability function that translates the boolean side of an order to a human readable string. For example, passing in `true` represents a buy order, so this function will return `"BUY"`, whereas passing in `false` will return `"SELL"`.

func RequireCancelOrderMessage 

func RequireCancelOrderMessage(t *testing.T, ctx sdk.Context, message *msgsender.Message, orderId types.OrderId)

func RequireCancelOrderOffchainUpdate 

func RequireCancelOrderOffchainUpdate(
	t *testing.T,
	ctx sdk.Context,
	offchainUpdate *types.OffchainUpdates,
	orderId types.OrderId,
)

Types

type CollateralizationCheck 

type CollateralizationCheck struct {

}

CollateralizationCheck is a testing utility struct used to represent a collateralization check.
