@japa/assert

Assertion library built on top of Chai.assert

An assertion library built on top of Chai.assert with small tweaks and additional features like assertion planning.

Installation

Install the package from the npm registry as follows:

npm i @japa/assert

yarn add @japa/assert

You can use the assertion package with the @japa/runner as follows.

import { assert } from '@japa/assert'
import { configure } from '@japa/runner'

configure({
  plugins: [assert()]
})

Once done, you will be able to access the assert property on the test context.

test('test title', ({ assert }) => {
  assert.deepEqual({ id: 1 }, { id: 1})
})

You can register open API schema and then assert HTTP responses against.

configure({
  plugins: [assert({
    openApi: {
      schemas: [new URL('../api-spec.json', import.meta.url)]
    }
  })]
})

Validate response as follows.

test('get users', ({ assert }) => {
  const response = await supertest(baseUrl).get('/users')
  assert.isValidApiResponse(response)
})
