Un ejemplo podría ser que tienes un proveedor de autenticación externo al que necesitas llamar.

Le envías un token y te devuelve un usuario autenticado.

Este proveedor podría estar cobrándote por cada request, y llamarlo podría tomar más tiempo adicional que si tuvieras un usuario mock fijo para los tests.

Probablemente quieras probar el proveedor externo una vez, pero no necesariamente llamarlo para cada test que se realice.
