@ethereum-waffle/mock-contract 2.4.1

This release addd MockContract functionality that allows to deploy dynamic contract mock and specify it's behavior, i.e.

const mockContract = await deployMockContract(wallet, contractAbi);
await mockContract.mock.<nameOfMethod>.returns(<value>)
await mockContract.mock.<nameOfMethod>.withArgs(<arguments>).returns(<value>)
await mockContract.mock.<nameOfMethod>.reverts()
await mockContract.mock.<nameOfMethod>.withArgs(<arguments>).reverts()

@ethereum-waffle/ens 2.4.1

This release introduces ENSBuilder, which allows to test smart contracts with ENS, i.e.

const ensBuilder: ENSBuilder = await createENSBuilder(wallet);
await ensBuilder.createTopLevelDomain('test');
await ensBuilder.createSubDomain('ethworks.test');
await ensBuilder.setAddress('vlad.ethworks.test', '0x001...03');

2.4.1

Changes:

• Add support for tuple types in the human readable abi
• Increase max output buffer size during native and docker compilation
• Fix big number matchers (e.g to.be.above)
• Add more big number matchers (gt, lt, gte, lte)

2.4.0

Features:

• new cleaner, simple configuration file, detailed description available in the documentation. The configuration file format is backward compatible.

Dependencies:

• Update ethers version from ^4.0.0 to ^4.0.45

Bug fixes:

• Fixed revertedWith('...') to work corretly with string argument

• Correct mismatched error reports reverted and not.reverted

• expect().to.emit.withArgs - recognises when an event is emitted multiple times with different args, e.g.

  expect(...).to
  .emit(contractA, "SuccessCall").withArgs(1)
  .emit(contractB, "SuccessCall").withArgs(0)

2.3.2

Changes:

• Introduce MockProviderLike interface that enables third party providers to use the legacy getWallets api.

2.3.1

This release fixes ganache's "Incompatible EIP155" error.

2.3.0

Changes:

• Istanbul support
• Add event emitted matcher negation support, e.g.:
  await expect(events.emitTwo()).to.not.emit(events, 'One');
• Migrate repository to a monorepo. Packages:
  • waffle-cli - direct successor to the previous repository root
  • waffle-chai - home of the chai matchers
  • waffle-provider - implementation of the MockProvider and fixtures
  • waffle-compiler - compilation of Solidity smart contracts
• Add MockProvider class
  • it extends providers.Web3Provider
  • you create it using new MockProvider(options?) instead of createMockProvider(options?)
  • use provider.getWallets() instead of getWallets(provider). This allows for a shorthand: new MockProvider().getWallets()
  • use provider.createEmptyWallet() to get a random Wallet without any ETH
• Deprecate createMockProvider
• Deprecate getGanacheOptions
• Deprecate getWallets
