* Add fixes to parsing and converting of fields in tx tests
* Correct logic in tx tests; validation of fields and correct
logic for when RLP decoding works/fails and when this is
expected or not
* Rename files for consistency
* Add block tests wrapper to run block tests with go test
This commit also changes the block test loading so tests containing
invalid RLP blocks can be loaded and return an error only when they are
run.
(cherry picked from commit 898ba87984)
* Include tests which now has consistent HEX encodings
* Comment out two failing tests: "
"TransactionWithHihghNonce" due to wrong nonce size
"TransactionWithSvalueHigh" due to wrong ECDSA s range
* Cleanup conversion functions and fix expected encodings for
tests validation fields
* Add initial go wrapping for TransactionTests with some tests
disabled in lieu of consistent HEX encodings and a few other
pending bugfixes
* TODO: Consider better way of perhaps modelling each test in
the JSON files as a single Go test, instead of one Go test per
JSON file
