How to use the @adonisjs/sink.Helpers function in @adonisjs/sink

test('make a model filter class', async (assert) => {
    const make = new MakeModelFilter(new Helpers(path.join(__dirname)))

    // Name without word 'Filter'
    await make.handle({ name: 'User' })
    const UserFilter = require(path.join(__dirname, './app/ModelFilters/UserFilter'))

    // Name with word 'Filter'
    await make.handle({ name: 'PostFilter' })
    const PostFilter = require(path.join(__dirname, './app/ModelFilters/PostFilter'))

    assert.equal(UserFilter.name, 'UserFilter')
    assert.equal(PostFilter.name, 'PostFilter')
    assert.instanceOf(new UserFilter(), ModelFilter)
  })

test('make a validator class', async (assert) => {
    const make = new MakeValidator(new Helpers(path.join(__dirname)))
    await make.handle({ name: 'User' })
    const User = require(path.join(__dirname, './app/Validators/User'))
    assert.equal(User.name, 'User')
    assert.deepEqual(new User().rules, {})
  })

    ioc.fake('Adonis/Src/Helpers', () => new Helpers(path.join(__dirname, `./projects/${name}`)))
    return ioc.use('Adonis/Src/Helpers')

ioc.bind('Adonis/Src/Helpers', () => {
    return new Helpers(path.join(__dirname))
  })

ioc.bind('Adonis/Src/Helpers', () => {
      return new Helpers(path.join(__dirname))
    })

const getContext = function () {
  const command = new ace.Command()
  return new Context(command, new Helpers(BASE_PATH))
}

    ioc.bind('Adonis/Src/Helpers', () => new Helpers(path.join(__dirname, '..', 'app')))
