🎬 Sagetest in action

There are several other methods which you can find in the API documentation. In general, the usage experience should resemble that of supertest.

Express Endpoint Testing

Example usage of auth method to set Basic Auth header based on username and password.

import { request } from '../src/index.js';

// Just a plain express app
const response = await request(app).get('/').auth('user', 'pass');

expect(response).toEqual({
  body: {
    message: 'I love my mom!',
    requestHeaders: {
      authorization: 'Basic dXNlcjpwYXNz',
      connection: 'close',
      host: expect.stringContaining('localhost')
    }
  },
  cookies: {
    'sweet-cookie': {
      httpOnly: true,
      path: '/',
      value: 'choco'
    }
  },
  error: false,
  headers: {
    connection: 'close',
    'content-length': '130',
    'content-type': 'application/json; charset=utf-8',
    date: expect.any(String),
    etag: expect.any(String),
    'set-cookie': 'sweet-cookie=choco; Path=/; HttpOnly',
    'x-powered-by': 'Express'
  },
  location: undefined,
  ok: true,
  redirect: false,
  status: 200,
  statusCode: 200,
  statusText: 'OK',
  text: expect.any(String) // Stringified body
});

Fastify Endpoint Testing

Example usage of auth method to set the Authorization header based on the provided token. Also, in response, you're able to validate cookies sent by the server.

import { request } from '../src/index.js';

// Don't forget to wait until all plugins are registered.
await fastifyApp.ready();

// Don't forget to use .server instead of plain fastify instance.
const response = await request(fastifyApp.server).get('/').auth('jwtToken');

expect(response).toEqual({
  body: {
    message: 'I love my mom!',
    requestHeaders: {
      authorization: 'Bearer jwtToken',
      connection: 'close',
      host: expect.any(String)
    }
  },
  cookies: {
    'sweet-cookie': {
      httpOnly: true,
      path: '/',
      value: 'choco'
    }
  },
  error: false,
  headers: {
    connection: 'close',
    'content-length': '127',
    'content-type': 'application/json; charset=utf-8',
    date: expect.any(String),
    'set-cookie': 'sweet-cookie=choco; HttpOnly'
  },
  location: undefined,
  ok: true,
  redirect: false,
  status: 200,
  statusCode: 200,
  statusText: 'OK',
  text: expect.any(String) // Stringified body
});
