Default configuration

This configuration is added automatically if the plugin is enabled:

    "config": [
      "jest.config.{js,ts,mjs,cjs,json}",
      "package.json"
    ],
    "entry": [
      "**/__tests__/**/*.[jt]s?(x)",
      "**/?(*.)+(spec|test).[jt]s?(x)"
    ]
  }

Your custom config or entry options override default values, they are not merged.
