Hi @msicilia,
Just checking in to see if you resolved?
For the latest version of @openzeppelin/test-helpers
OpenZeppelin Test Helpers 0.5 - #3 by abcoathup
As per how to upgrade from 0.4 I needed to change in my migrations (2_deploy.js
)require('@openzeppelin/test-helpers/configure')({ web3 });
to
require('@openzeppelin/test-helpers/configure')({ provider: web3.currentProvider, environment: 'truffle' });
