* add some unit tests for estimateGas Also add some test environment setup, Closes #323 test estimateGas of erc20 token transfer fix failed test case the trick is to keep a clean transient store, by doing a commit put artifacts to external file * fix test failure Co-authored-by: Federico Kunze Küllmer <31522760+fedekunze@users.noreply.github.com>
