MockContainerRuntime Class

Mock implementation of IContainerRuntime for testing basic submitting and processing of messages. If test specific logic is required, extend this class and add the logic there. For an example, take a look at MockContainerRuntimeForReconnection.

This API is provided for existing users, but is not recommended for new users.

To use, import via @fluidframework/test-runtime-utils/legacy.

For more information about our API support guarantees, see here.

flushSomeMessages(numMessages)	Beta		void	If flush mode is set to FlushMode.TurnBased, it will send the specified number of messages from the outbox queued since the last time this (or flush) was called. Otherwise, calling the method does nothing. This can be useful when simulating staging mode, and we only want to flush certain messages.
