Test size of operations
Write a test that ensures that the sizes of operations match some known constant, so that in the future it will catch changes that might impact the size of the blockchain.
To know the size in bytes of all operations, one can create an operation, serialize it to binary and then measure the length.
Many operations contain fields that are of variable length, for example all the Z.t, in this case just use a fixed value.
e.g. when measuring a transaction consider an mount of 1 Tez, for all manager operations consider a fee of 1 Tez
