Ethereum client testing rarely gets front page treatment, but it is one of the quiet places where protocol risk either shrinks or compounds. A draft Geth change adds a direct evm enginetest runner for Engine API fixtures, and the numbers are blunt: tens of thousands of execution tests can move from hours to seconds on local hardware.
