Summary
Jest 27 sets default test environment to
node
, see jestjs/jest#9874. Since we needjsdom
so we need to explicitly set it injest-preset.js
.Jest 27 will still bundle
jest-environment-jsdom
in the main package and Jest 28 will separate them. However, we should just go ahead and set explicitlyjest-environment-jsdom
in our dependencies list.More information see https://jestjs.io/blog/2020/05/05/jest-26
