Why does this change? This transaction field in the spec is called max_priority_fee_per_gas and is what is added on top of block base fee.

Ah I guess because default is legacy transaction? It's confusing that Transaction has this field for legacy.

Legacy transaction requires these values to be the same. So I made the default agree as well.
Maybe this is not great for clarity of tests, but EIP-1559 calculations work for legacy transactions if these two fields have the same value of legacy gas price.

Can't these calculations check transaction type and ignore this field (i.e. consider it equal max_gas_price) for legacy?

Or another idea is that Transaction constructor for legacy should enforce this

Yes they can, but there is no time to do this change now.

Then at least add
assert(tx.type != Legacy || tx.max_priority_gas_price == tx.max_gas_price);
to state transition.

But it also can be just
if (tx.type == Legacy)
tx.max_priority_gas_price = tx.max_gas_price;

I improved the asserts in TearDown() a bit.
It looks to me that we should have something like TestBlock with every field std::optional and set default values only after test definition. Otherwise, the test definitions must fight with defaults.

This may not be the best idea because e.g. geth doesn't understand "Tangerine Whistle".

I changed this to export as EIP150 and EIP158... We still accept full revision names.

@winsvega usually says it should be at least 7 in tests, but I'm not sure exactly why

It is the minimal value by the spec.
