A sweet set of chai matchers for your blockchain testing needs.
In the current version of waffle (v2.x.x) you will install this package as a dependency of the main waffle package - ethereum-waffle.
yarn add --dev ethereum-waffle
npm install --save-dev ethereum-waffle
If you want to use this package directly please install it via:
yarn add --dev @ethereum-waffle/chai
npm install --save-dev @ethereum-waffle/chai
NOTE: You do not need to use this package directly. You can install it through the main package (ethereum-waffle) and use it instead.
