[v4] When running npm run test, hooks.before.httpServer not triggered?

In my /start/hook.js, i have this:
which extends the validator and adds a uuid validation, in my current version I do not have that uuid validation.
This works perfectly, but does not work when I run the tests.

hooks.before.httpServer(() => {
  const Validator = use('Adonis/Addons/Validator')
  const isUuid = require('uuid-validate')

  Validator.extend('uuid', (data, field, message, args, get) => new Promise((resolve, reject) => {
    const value = get(data, field)
    if (!value) return

    if (isUuid(value)) {
      resolve('The field is a uuid')
      return
    }

    reject(message)
  }), 'The field is not a uuid')
})

So in my tests I created a test for updating orders:

...
const response = await client
    .patch(`/orders/${order.id}`)
    .loginVia(user, 'jwt')
    .send(order)
    .end()
..

Now in my controller I have a rule which validated if a property is a uuid:

  delivery_occurrence_id: 'required|uuid'

and there is where I get the error:

{
   "message":"uuid is not defined as a validation rule",
   "field":"delivery_occurrence_id",
   "validation":"ENGINE_EXCEPTION"
}',

The problem was that I extended the validator at the before.httpServer hook event and I should have set it at before.providersBooted.
