// Default of 8 ECs is not sufficient for some of the unit tests
// that try to validate multiple simultaneous interactions.
// In tests like TestReadHandler_MultipleSubscriptions, we are trying to issue as many read / subscription requests as possible in
// parallel. Since the default config says we support 16 fabrics, and we will have 4 read handlers for each fabric (3 subscriptions
// + 1 reserved for read) that is read transactions in parallel. Since the report handlers are allocated on the heap, we will issue
// 65 requests (the TestReadHandler_MultipleSubscriptions will issue CHIP_IM_MAX_NUM_READ_HANDLER + 1 subscriptions to verify heap
// allocation logic) in total and that is 130 ECs. Round this up to 150 ECs
