Sync coreth test cleanup v2 #1623

JonathanOppenheimer · 2025-07-09T14:19:15Z

Largely mirrors ava-labs/coreth#950, but this time I don't make mistakes 😎

Do note that this PR goes beyond a simple drop in and replace in from ava-labs/coreth#950 as the testing framework upgrade had implications for tests and functionality not included in coreth (which is why I messed up on first revision)

No breaking changes

Does not require release notes

If someone with additional context could explain why this is necessary here, but was able to be removed in https://github.com/ava-labs/coreth/pull/950/files#r2080300565, that would be appreciated. Did I miss something?

I think the only difference is in Verify() where we pass c.SnowCtx.NetworkUpgrades. I think we should explicitly handle that in tests.

I do not know why this changed or why it worked before. Again would appreciate another set of eyes and brain!

These two lines are functionally identical except that EqualValues assumes type compatibility?? Really lost as to why this worked.

subnet-evm does upgrades

I frankly don't know why tests are broken and why it does not show anything. but it looks like something is broken in plugin/evm/ tests

can we revert these?

This is a linting error that error comments should not be capitalized. Still revert?

shouldn't this be secp256k1.TestKeys()[:3]?

No, unlike coreth, only, the highest index of any key used is [1], so only 2 keys are necessary.

I thought this was genesisJSON in coreth

It is; however there are multiple declarations of genesisJSON as a string, which leads to namespace collisions, so I renamed the function.

can we initialize them here as genesisJSONPreSubnetEVM = toGenesisJSON(params.TestPreSubnetEVMChainConfig)

I tried this but couldn't figure out a good way to do it - I initialized them in init() after the new ETH addresses were funded. If I did so before funding, I would get test errors about insufficient balances. In the prior rendition, static addresses were used which allowed them to be funded ahead of time.

I feel like we should not need that and just use genesisJson option in newVM

Even if this would diverge further from coreth? Unless you're asking about the argument - not sure what you mean
