Event Rules support retroactively testing them against the entire collection of Events in the system. This means that Reflex will attempt to test the Rule against all events in any state.
In multi-tenant environments, if the Global Rule is switched to
YES, then the test will be done across all tenants.
Because testing across a large set of events is time consuming, it is recommended to fine tune the testing criteria by selecting a relevant start and end date as well as adjusting the
Number of test events to something reasonable (which is
1,000 Events by default).
