I'd prefer the general config it would be nice to refer to these with their semi-"official" names, such as SpuriousDragon and TangerineWhistle.

Still we need docs on what those names mean exactly. What changes are applied.

This would be a good candidate for a PR on its own.

I was planning to run all existing tests with RPC.
Now I see that there are lost of issues and it will take much more time to cover this.
Another issue is that methods format might change in the future.

If you fine with that. I could start refactoring this PR and split it into multimple if you want.
Please keep the existing testeth in this repo for now. (travis automatition) I dont want to break existing test cases in cpp client.

Not sure what these shouldStop expressions are doing but it seems it would be better to have it as a PR on its own?

I will put small changes from this PR into a separate and then rebase this on top develop.
this shouldStop() accelerating blockchain reset. Is is a tweak by Andrey. Perhaps better be moved to TestClient.cpp

These seems to be a bugfix?

yes. it resolve setAuthor issue

Do you want to create a new PR for the bugfix?

This seems to be a bugfix?

yes. because empty() is true if there is no "to" json section.
but the string in this section could be empty or 0x (looks like no consensus on format here)

Should there be a PR for this bugfix?

ask/bid price PR is yet not merged.

How is that relevant?

I don't want to track many PRs at the same time.
ok. I have now finished fixing the tests and could concentrate on PRs here.

This should be moved to a generic place I'd assume. The client should also print this on start.

Also if not moved elsewhere, should be placed into the anonymous namespace.

this one copied from test namespace. however libwe3jsonrpc should not have deps on test namespace

I think it should be a generic helper available allover cpp-eth, what do you think @chfast and @gumb0 ?

How is this different to https://github.com/ethereum/wiki/wiki/JSON-RPC#web3_clientversion ? It seems you are just returning the version.

in that case. no need to implement a new method.
I am removing it from the list of test RPC methods:
ethereum/retesteth#5

Can you remove it from this PR then?

winsvega · 2018-03-22T18:38:52Z

@chfast seeing how a 1 line commit takes about 2 weeks to get merged. I guess this branch stays as experimental. and to merge changes from this branch I will open series of PRs with small changes. then just rebase this branch untill no changes left.

chfast · 2018-03-22T21:12:18Z

If you refer to #4895, maybe it's time to fix the broken tests?

no reward for StateTests.
for BlockchainTests reward should be enabled.

I don't understand. This change does not make sense to me.

this is not the change. its a work around. currently there is no way to set mining reward from the config option.
Andrey said that mining reward must present and be hardcoded by the fork rules.
I guess this means no StateTests support then. But we actually dont need state tests because if you run it with test_mineBlocks anyway. there would be no difference between state and blockchain test then.

so this line could be removed

still not clear, what do you want us to do with this PR now?

we need to agree on genesis scheme ethereum/tests#469
