 +También podemos aprovechar para modificar el script ''test'' de forma que lance todos los tests: unitarios y de integración:
 +
 +<code javascript>
 +. . .
 +"scripts": {
 +    . . .
 +    "test": "npm run unit-test && npm run integration-test",
 +    . . . 
 +. . .

 +
 +Asi, podremos lanzar todos los tests solo con ''npm test''
