Testing - Twenty Documentation

The SDK provides programmatic APIs that let you build, deploy, install, and uninstall your app from test code. Combined with Vitest and the typed API clients, you can write integration tests that verify your app works end-to-end against a real Twenty server.

Using npm packages

You can install and use any npm package in your app. Both logic functions and front components are bundled with esbuild, which inlines all dependencies into the output — no node_modules are needed at runtime.

Installing a package

yarn add axios

Then import it in your code:

src/logic-functions/fetch-data.ts

import { defineLogicFunction } from 'twenty-sdk/define';
import axios from 'axios';

const handler = async (): Promise<any> => {
  const { data } = await axios.get('https://api.example.com/data');

  return { data };
};

export default defineLogicFunction({
  universalIdentifier: '...',
  name: 'fetch-data',
  description: 'Fetches data from an external API',
  timeoutSeconds: 10,
  handler,
});

The same works for front components:

src/front-components/chart.tsx

import { defineFrontComponent } from 'twenty-sdk/define';
import { format } from 'date-fns';

const DateWidget = () => {
  return <p>Today is {format(new Date(), 'MMMM do, yyyy')}</p>;
};

export default defineFrontComponent({
  universalIdentifier: '...',
  name: 'date-widget',
  component: DateWidget,
});

How bundling works

The build step uses esbuild to produce a single self-contained file per logic function and per front component. All imported packages are inlined into the bundle. Logic functions run in a Node.js environment. Node built-in modules (fs, path, crypto, http, etc.) are available and do not need to be installed. Front components run in a Web Worker. Node built-in modules are not available — only browser APIs and npm packages that work in a browser environment. Both environments have twenty-client-sdk/core and twenty-client-sdk/metadata available as pre-provided modules — these are not bundled but resolved at runtime by the server.

Setup

The scaffolded app already includes Vitest. If you set it up manually, install the dependencies:

yarn add -D vitest vite-tsconfig-paths

Create a vitest.config.ts at the root of your app:

vitest.config.ts

import tsconfigPaths from 'vite-tsconfig-paths';
import { defineConfig } from 'vitest/config';

export default defineConfig({
  plugins: [
    tsconfigPaths({
      projects: ['tsconfig.spec.json'],
      ignoreConfigErrors: true,
    }),
  ],
  test: {
    testTimeout: 120_000,
    hookTimeout: 120_000,
    include: ['src/**/*.integration-test.ts'],
    setupFiles: ['src/__tests__/setup-test.ts'],
    env: {
      TWENTY_API_URL: 'http://localhost:2020',
      TWENTY_API_KEY: 'your-api-key',
    },
  },
});

Create a setup file that verifies the server is reachable before tests run:

src/__tests__/setup-test.ts

import * as fs from 'fs';
import * as os from 'os';
import * as path from 'path';
import { beforeAll } from 'vitest';

const TWENTY_API_URL = process.env.TWENTY_API_URL ?? 'http://localhost:2020';
const TEST_CONFIG_DIR = path.join(os.tmpdir(), '.twenty-sdk-test');

beforeAll(async () => {
  // Verify the server is running
  const response = await fetch(`${TWENTY_API_URL}/healthz`);

  if (!response.ok) {
    throw new Error(
      `Twenty server is not reachable at ${TWENTY_API_URL}. ` +
        'Start the server before running integration tests.',
    );
  }

  // Write a temporary config for the SDK
  fs.mkdirSync(TEST_CONFIG_DIR, { recursive: true });

  fs.writeFileSync(
    path.join(TEST_CONFIG_DIR, 'config.json'),
    JSON.stringify({
      remotes: {
        local: {
          apiUrl: process.env.TWENTY_API_URL,
          apiKey: process.env.TWENTY_API_KEY,
        },
      },
      defaultRemote: 'local',
    }, null, 2),
  );
});

Programmatic SDK APIs

The twenty-sdk/cli subpath exports functions you can call directly from test code:

Function	Description
`appBuild`	Build the app and optionally pack a tarball
`appDeploy`	Upload a tarball to the server
`appInstall`	Install the app on the active workspace
`appUninstall`	Uninstall the app from the active workspace

Each function returns a result object with success: boolean and either data or error.

Writing an integration test

Here is a full example that builds, deploys, and installs the app, then verifies it appears in the workspace:

src/__tests__/app-install.integration-test.ts

import { APPLICATION_UNIVERSAL_IDENTIFIER } from 'src/application-config';
import { appBuild, appDeploy, appInstall, appUninstall } from 'twenty-sdk/cli';
import { MetadataApiClient } from 'twenty-client-sdk/metadata';
import { afterAll, beforeAll, describe, expect, it } from 'vitest';

const APP_PATH = process.cwd();

describe('App installation', () => {
  beforeAll(async () => {
    const buildResult = await appBuild({
      appPath: APP_PATH,
      tarball: true,
      onProgress: (message: string) => console.log(`[build] ${message}`),
    });

    if (!buildResult.success) {
      throw new Error(`Build failed: ${buildResult.error?.message}`);
    }

    const deployResult = await appDeploy({
      tarballPath: buildResult.data.tarballPath!,
      onProgress: (message: string) => console.log(`[deploy] ${message}`),
    });

    if (!deployResult.success) {
      throw new Error(`Deploy failed: ${deployResult.error?.message}`);
    }

    const installResult = await appInstall({ appPath: APP_PATH });

    if (!installResult.success) {
      throw new Error(`Install failed: ${installResult.error?.message}`);
    }
  });

  afterAll(async () => {
    await appUninstall({ appPath: APP_PATH });
  });

  it('should find the installed app in the workspace', async () => {
    const metadataClient = new MetadataApiClient();

    const result = await metadataClient.query({
      findManyApplications: {
        id: true,
        name: true,
        universalIdentifier: true,
      },
    });

    const installedApp = result.findManyApplications.find(
      (app: { universalIdentifier: string }) =>
        app.universalIdentifier === APPLICATION_UNIVERSAL_IDENTIFIER,
    );

    expect(installedApp).toBeDefined();
  });
});

Running tests

Make sure your local Twenty server is running, then:

yarn test

Or in watch mode during development:

yarn test:watch

Type checking

You can also run type checking on your app without running tests:

yarn twenty dev:typecheck

This runs tsc --noEmit and reports any type errors.

CI with GitHub Actions

The scaffolder generates a ready-to-use GitHub Actions workflow at .github/workflows/ci.yml. It runs your integration tests automatically on every push to main and on pull requests. The workflow:

Checks out your code
Spins up a temporary Twenty server using the twentyhq/twenty/.github/actions/spawn-twenty-docker-image action
Installs dependencies with yarn install --immutable
Runs yarn test with TWENTY_API_URL and TWENTY_API_KEY injected from the action outputs

.github/workflows/ci.yml

name: CI

on:
  push:
    branches:
      - main
  pull_request: {}

env:
  TWENTY_VERSION: latest

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        uses: actions/checkout@v4

      - name: Spawn Twenty instance
        id: twenty
        uses: twentyhq/twenty/.github/actions/spawn-twenty-docker-image@main
        with:
          twenty-version: ${{ env.TWENTY_VERSION }}
          github-token: ${{ secrets.GITHUB_TOKEN }}

      - name: Enable Corepack
        run: corepack enable

      - name: Setup Node.js
        uses: actions/setup-node@v4
        with:
          node-version-file: '.nvmrc'
          cache: 'yarn'

      - name: Install dependencies
        run: yarn install --immutable

      - name: Run integration tests
        run: yarn test
        env:
          TWENTY_API_URL: ${{ steps.twenty.outputs.server-url }}
          TWENTY_API_KEY: ${{ steps.twenty.outputs.access-token }}

You don’t need to configure any secrets — the spawn-twenty-docker-image action starts an ephemeral Twenty server directly in the runner and outputs the connection details. The GITHUB_TOKEN secret is provided automatically by GitHub. To pin a specific Twenty version instead of latest, change the TWENTY_VERSION environment variable at the top of the workflow.
