# EPF Update: Weeks 18 & 19

## Metrics
I added more metrics similar to those in past Reth updates. These metrics are for local block building of blocks with ILs. They track the number of included transactions and a reason for each transaction that is not included in a locally built block.

## Testing
I added the primitives for FOCIL to my Hive fork. I am not sure how much is needed, but it is a good starting point as testing continues. After submitting my PR to EEST and making changes that Jihoon suggested, I have an initial list of tests to write for FOCIL. I just opened a PR to EELS, as EEST tests are being moved into EELS now.

Since the initial list is complete, I have started writing the Python tests to test these cases. Currently, I have 9 tests written, all of which build proper fixtures and pass when run against Reth through Hive. So far, there have been no bugs found in Reth from these tests. As I move to finish the rest of the tests, I will start testing against other execution clients. For the remaining tests, I am evaluating if they can actually be tested in EELS due to the scope of the test. So these tests may need to be moved elsewhere.

## Next Steps
* Write more tests
* Figure out how to implement tests for block building and IL building
* Rebase Reth
