For implementing a Store functionalities and tests by using StoreKit2, I have a task listener and two testcases.
The first one is waiting the update notification before processing the next SKTestSession operation.The second one is not waiting the update.
I looked update events theree times on first one, and twice on second one.
My question is, "Do multiple transactions created or modified within a certain period be emitted as a single Transaction.updates event?"

Testcase2
The behavior you're seeing appears to be expected. Transaction.updates will always emit the latest updated transaction that StoreKit is aware of. There will always be a delay between a transaction updating on the server, and StoreKit emitting the transaction. With StoreKit Testing in Xcode and StoreKitTest, this delay is much less compared to the App Store or sandbox environment, since these environments are local to your device rather than on a remote server.
If a transaction updates happen in very quick succession as in your second test case, you may only receive a single new value for each unique transaction ID from Transaction.updates because of this delay. These values will always reflect the latest state of the transaction.
