testSerializeThenParse @vuqs/core/testing

Checks one direction: parse(serialize(input)) equals input (by codec.eq).

Usage

import { codecs } from '@vuqs/core'
import { testSerializeThenParse } from '@vuqs/core/testing'
import { expect } from 'vitest'

expect(testSerializeThenParse(codecs.integer, 42)).toBe(true)
expect(() => testSerializeThenParse(codecs.integer, Number.NaN)).toThrow()

Type

function testSerializeThenParse<T>(codec: Codec<T>, input: T): boolean

Parameters

• codec: Codec<T>
  • The codec under test.
• input: T
  • The value to serialize and parse back.

Return value

• valid: boolean
  • true when the round-trip succeeds. Throws if the codec rejects its own serialized output, or if the round-tripped value differs.
