React app rewired jest. It also automatically sets up jest to compile the project with babel prior to running tests. However there is a way to customize it, you can put your jest configuration in the root of your package.json: Steps to reproduce the behavior:

Create react app rewired application ignoring jest.config.js. The format to use in the babel section of package.json or the.babelrc file is documented separately at the babel website. Jest is a javascript based test runner, which allows tests to be run blazing fast and in parallel.

Use jest/enzyme to build robust test suites for your react application jest. Add plugin to the.babelrc config file: It also automatically sets up jest to compile the project with babel prior to running tests.

This is more than simple alias. 在根目录下生成 jest.config.js 的配置文件，scripts里添加的jest命令会在 jest.config.js 里找配置. But as @andreas mentioned, if you want full control, eject or create your own config.

This is causing the issue. I have a react application created using create react app rewired. Here is the configuration i was using before 1.0.10 and that was working:

React ui 组件库的 jest 单元测试. I map some modules in tsconfig.json. The format to use in the babel section of package.json or the.babelrc file is documented separately at the babel website.
