Sourced from openzeppelin-test-helpers's changelog.

0.5.1 (2019-10-10)

• Removed check for truffle environments on configure due to issues with truffle migrations.

0.5.0 (2019-10-10)

• Renamed the package to @openzeppelin/test-helpers. (#78)
• Removed hard-dependency on truffle-contract (#75):
  • An environment option was added to configure, and can be set to either web3 or truffle (default is web3, but there is automatic detection of a truffle environment)
  • singletons return web3 Contract instances when environment is set to web3
  • expectEvent.inLogs was deprecated in favor of expectEvent, which receives the full receipt object (not just the logs), and supports both web3 and truffle contract receipts
• Improved how revert reason checks (expectRevert) are handled on unsupported environments. (#80)
• Breaking: configure's web3 argument was removed and replaced by provider, which can be either a web3 provider or a connection string. The default is http://localhost:8545, unless a global web3 instance is found, in which case web3.currentProvider is used.
• Add optional unit argument to balance functions. (#79)

How to upgrade from 0.4

The package has been renamed to @openzeppelin/test-helpers, so please uninstall openzeppelin-test-helpers and reinstall it with the new name.

npm remove openzeppelin-test-helpers
npm install --save-dev @openzeppelin/test-helpers

If you are using openzeppelin-test-helpers in a Truffle environment with automatic configuration, there is nothing you need to do. If you were manually configuring a web3 instance, you will need to configure the provider instead. The specifics will depend on your setup, but the following should get you started.

-require('openzeppelin-test-helpers/configure')({ web3: myWeb3 });
+require('@openzeppelin/test-helpers/configure')({ provider: myWeb3.currentProvider });

Additionally, Truffle migrations require explicit environment configuration, since automatic detection does not work.

require('@openzeppelin/test-helpers/configure')({ provider: web3.currentProvider, environment: 'truffle' });

• Renamed makeInterfaceId to makeInterfaceId.ERC165, and added makeInterfaceId.ERC1820. (#21)

• Replaced shouldFail with expectRevert, with an improved API. (#39)
• Fixed detection of Ganache pre-releases (such as those used by Ganache GUI v2.0.1). (#46)
