[Feature]: config.ci option

[anthony-hayes]

🚀 Feature Proposal

Have a setting for the --ci flag in jest config files

Motivation

I'd like to use a single test script for both local and ci, and enable jest's --ci mode when CI=true (i.e. I'm running in CI such as GitHub actions)

I'm happy to do this env var check in the jest.config.js, but there's no way to set the ci mode from the config file: https://jestjs.io/docs/configuration

This is important for me when working with a monorepo, to avoid duplicated scripts in many package.json files to allow bulk running of tests with something like turbo run test and to avoid forcing folks to add a test:ci script to every package.json

Example

No response

Pitch

For flexibility, command line options should have a corresponding config file setting

Looks like the --ci option isn't needed in new versions of jest, as updating snapshots is opt-in. Closing this
