@marioevz @winsvega I'm working on several more precompile tests and double checking that all cases are covered.

• Blake2b should be covered with these additions, but one case is causing timeouts (see separate comment below).
• This PR includes a couple Identity test cases. There are numerous others for CALL and CALLCODE that I will add here.

I want to clarify the other test cases since you mentioned skipping a few from the stPreCompiledContracts2 directory.

• Am I remembering that you said to ignore the ecrecover, ripemd and sha256 tests? I dont know if there might be others, but wanted to check back before I proceed further.
• I noticed a single test case in https://github.com/ethereum/tests/blob/develop/src/GeneralStateTestsFiller/stPreCompiledContracts/sec80Filler.json that appears to be related to the ecrecover precompile (I found it runs CALLCODE to address 0x1). Should this one be ignored?
• The precompile EIP2929 tests should probably be converted. I wanted to check before implementing those, they appear to check gas consumption of certain opcodes. https://github.com/ethereum/tests/blob/develop/src/GeneralStateTestsFiller/stPreCompiledContracts/precompsEIP2929CancunFiller.yml
• EIP-2929 test conversions are in feat(tests) EIP-2929: Gas cost increase tests #1305

add tests to converted file to run check the coverage

[winsvega]

add converted-tests .txt records to check run the coverage

@winsvega @marioevz Coverage added and failing from the two cases that I have commented out due to the extreme number of rounds used. The test hangs and times out so I would guess we can ignore those. Is there a way to explicitly flag those cases so the coverage report passes?

[marioevz]

Added a line to converted-ethereum-tests.txt to trigger coverage run again 👍

Hey, some comments that would make use of some pytest features to remove some code duplication. Thanks!

Test coverage is failing due to one case being skipped in test_blake2b_large_gas_limit due to timeouts. delegatecall coverage has also changed due to differences in setup, specifically with preallocations of accounts in the original tests.
