Standard set of test raw blocks and transactions that stress all edge cases

[AustEcon]

I have a fair idea of most of the pitfalls that need to be handled wrt indexing the chain.

Things like handling of malformed output scripts (which can legitimately happen where they do not comply with bitcoin script syntax rules). Or coinbase scripts do not get checked so can just find total junk in there... or weird stuff happens like the coinbase can make the txid be non-unique! (but only for coinbases as a special case)

But also the "happy path" of correctly parsing all pushdatas / opcodes.

So I think a set of hand-crafted raw blocks and raw transactions with expected output would be nice (but might be a bit tedious to make...)

I've often found myself wishing that something like this existed for a number of bitcoin-related projects.

For the wallet you really want a set of transactions that systematically map out all of the most common script types to stress all the edge cases too.

I wonder if it would be best to generate these and then you can rebuild the set.

Yeah that's probably the easiest way. Just generate a block on RegTest densely packed with all of the trouble-maker transactions perhaps and then gather up all the utxos... the full state of the chain and capture it for testing?

I don't think you can make custom coin bases when mining blocks but for everything else would be ideal.

Or maybe they just get generated anew each test run and can extend the generator over time to be more comprehensive

I think we need to be able to make custom coin bases if we want to test miner id, but actually emulating that might be outside the scope of our sdk.
