The main motivation for this is upgrading linters to their latest major versions.
eslint-config-skyscanner will try to detect automatically the version of Jest installed.
If your project doesn't use it or it is not installed in the same package.json as eslint-config-skyscanner, it must be manually set in .eslintrc to your desired version:
"settings": {
"jest": {
"version": "VERSION"
}
}
jest/no-large-snapshotshttps://github.com/jest-community/eslint-plugin-jest/blob/master/docs/rules/no-large-snapshots.md- This rule has a big impact as it means that test files would need to be broken down further so that the generated snapshot files could shrink but this might be difficult on some snapshots where the component being tested, is rendered on many lines.
