[General] How equivalence does op-geth have?

[realtakahashi]

Discussion Topic

I want to know how equivalent does op-geth have, differ with the EVM on Ethereum L1.
Do you have any test code for checking the equivalence? like "ethereum test"?(https://github.com/ethereum/tests)

https://docs.optimism.io/stack/differences
and if you check the code,op-geth is reference testdata as you mentioned(but not the latest test)

I’m not aware of any test code, but this page lists the code differences between geth and op-geth.
https://op-geth.optimism.io

Additionally, RollupCodes can also be a good source of information.

Thank you for giving informations, guys.
But I want to execute the tests which check the equivalence against OP by myself.
That's why I am asking this question.

You might want to take a look at this directory
https://github.com/ethereum-optimism/op-geth/tree/optimism/tests

or you can also check this repo.

Do you have any other questions? If not, I'd like to go ahead and close this ticket.

I am also interested in this question.
Do you know if the op-geth compatibility tests use, for example, the “Ethereum Execution Tests” (https://github.com/ethereum/tests)?
Can the “Ethereum Execution Tests” be run as-is against op-geth?

Please refer to this response.

It's unclear whether the ethereum/tests can be run directly against op-geth, but since some of the opcodes in the OP Stack are customized, even if they can be executed as-is, the coverage would likely be insufficient.
