+If you wish to test with concurrency, the `Supplier` lambda in the factory's constructor would need to create a new instance each time.
 
 With the `MockProducerFactory`, there are two constructors; one to create a simple factory, and one to create factory that supports transactions.

 If you are using producers in a multi-threaded environment, the `BiFunction` should return multiple producers (perhaps thread-bound using a `ThreadLocal`).
 
 IMPORTANT: Transactional `MockProducer`+++s+++ must be initialized for transactions by calling `initTransaction()`.
+
+When using the `MockProducer`, if you do not want to close the producer after each send, then you can provide a custom `MockProducer` implementation that overrides the `close` method that does not call the `close` method from the super class.
+This is convenient for testing, when verifying multiple publishing on the same producer without closing it.
