# 13.4 Agregar pruebas a tus servicios

Puedes agregar el cóodigo javascript para probar que lo que regresa el servicio es correcto. 

{% hint style="info" %}
Se sugiere probar los casos de uso correctos e incorrectos, y probar que se regresen correctamente los resultados.
{% endhint %}

Para probar que el servicio de login con un usuario correcto validaré lo siguiente:

* Que el servicio regrese un status 200
* Que el servicio regrese un token que no este vacío

Para probar tipos de datos voy a probar

* Que el token sea string
* Que la fecha de expiración del token sea un date con el formato

   //Revisar Estatus 200
   pm.test("Estatus es 200", function () {
       pm.response.to.be.ok;
   });

   //Convertir el Json a un objeto
   var respuesta = pm.response.json();

   pm.test("Token no es vacío", function() 
   {
       pm.expect(respuesta.Token).not.to.be.empty;
   });

   pm.test("Token es string", function() 
   {
       pm.expect(respuesta.Token).to.be.a('string');
   });

   pm.test("Token Expiration es una fecha correcta", function () {
      pm.expect(moment(respuesta.TokenExpiration,"MM-MM-DD hh:mm:ss").isValid()).to.be.true

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://abi.gitbook.io/net-core/14.-introduccion-a-postman/14.4-agregar-pruebas-a-tus-servicios.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
