What's new in 2.0

Documentation

Documentation is now available. Check it out under the URL: https://ethereum-waffle.readthedocs.io/.

Faster compilation with native and dockerized solc

By default, Waffle uses solcjs. Solcjs is solidity complier cross-complied to javascript. It can be slow for bigger projects but require no installation. You can now use native and dockerized solc instead.

New chai matcher: changeBalance and changeBalances

Waffle 2.0 introduces changeBalance and changeBalances matchers that allow to check if a balance of an account(s) changed.

Read more about new matchers here.

Support for TypeScript

The code is now rewriteen in TypeScript and we offer partial TypeScript support. For now, it does not include chai matchers. We plan to include full TypeScript support in version 2.1

Fixtures

When testing code dependent on smart contracts it is often useful to have a specific scenario play out before every test. That leads to repetition and slow code execution. With fixtures, you can clean-up your code and speed it up by order of magnitude.

Others

• Waffle now supports config files with both json and js extensions.
• Contract linking should work for both solidity 4 and solidity 5

Breaking changes
