Test format

State Tests

Treat legacy blockheader as 1559 with baseFee 10 on London
Tests are recalculated with transaction gasPrice set to 10

Blockchain Tests

Tests are recalculated with transaction gasPrice set to 1000
Tests with gasPrice 0 are not included in London (as minimum baseFee is 7)

State Tests | BlockchainTests | TransitionTests

• the env section now could have

currentBaseFee: 0x3B9ACA00

indicating a eip1559 genesis.

• transaction section eip1559 support could now have

  maxFeePerGas: '0x12A05F200'
  maxPriorityFeePerGas: '2'

instead of gasPrice
PR example: #826

BlockchainTests | TransitionTests

• the blockHeader now could have

baseFee: 0x3B9ACA00

indicating a eip1559 block.
In blockchain fillers blocks section, the blockHeader (overwrite) section has a new field

               "blockHeader" : {
                   "gasLimit" : "600000",
                   "remove" : [ "baseFee" ]
               },

"remove" that indicates an array of fields to be removed from the client returned structure. making it possible to switch mined block into legacy and eip1559 back and forth. see transition test example.
