 The `location` property has `column` and `line` values that correspond to the `test` or `describe` position in the original file.
 
+This option will be auto-enabled if you don't disable it explicitly, and you are running Vitest with:
+- [Vitest UI](/guide/ui)
+- or using the [Browser Mode](/guide/browser) without [headless](/guide/browser#headless) mode

 ::: tip
 This option has no effect if you do not use custom code that relies on this.
