   FWIW the only alternative I know is to do what we do in IOx and sprinkle setup in all the tests:
   
   https://github.com/search?q=repo%3Ainfluxdata/influxdb_iox%20maybe_start_logging&type=code
   
   e.g. 
   ```rust
       #[test]
       fn test_panic_counter_and_logging() {
           maybe_start_logging();
   ```
   
   Do you know a better pattern to enable logging during unit test run?
