Testing Helper

The Testing Helper provides functions to make testing of Hono applications easier.

Import

npm

import { Hono } from 'hono'
import { testClient } from 'hono/testing'

testClient()

The testingClient() takes an instance of Hono as its first argument and returns an object of the Hono Client. By using this, you can define your request with the editor completion.

import { testClient } from 'hono/testing'

it('test', async () => {
  const app = new Hono().get('/search', (c) => c.json({ hello: 'world' }))
  const res = await testClient(app).search.$get()

  expect(await res.json()).toEqual({ hello: 'world' })
})
