Can we create Munit for on Error propagate in mule 4? - mule4

Question

Does on Error Propagate Munit should fail or pass?
Scenario:
When I get db connectivity error, it triggers email with error notification. Flow reference to Error email flow. Flow reference is placed in On Error Propagate.
I have mocked database with Error, DB CONNECTIVITY in error tab and wrap flow Ref in Try block. My tests are failing.
Test suite should fail with error message or pass with green colour in Munit tests?
