If you are already using jest-cli
, add babel-jest
and it will automatically compile JavaScript code using Babel.
yarn add --dev babel-jest @babel/core
If you would like to write your own preprocessor, uninstall and delete babel-jest and set the config.transform option to your preprocessor.
Note: this step is only required if you are using babel-jest
with additional code preprocessors.
To explicitly define babel-jest
as a transformer for your JavaScript code, map .js files to the babel-jest
module. Typescript files are also supported.
