Next.js Quickstart

Learn how to setup visual testing in a Next.js project using Argos.

The best way to integrate Argos with Next.js is to setup Playwright in your project.

Prerequisites

To get the most out of this guide, you’ll need to:

1. Install

Get the Argos Playwright SDK.

npm
yarn
pnpm
bun

npm i --save-dev @argos-ci/playwright

yarn add --dev @argos-ci/playwright

pnpm add --save-dev @argos-ci/playwright

bun add --dev @argos-ci/playwright

2. Setup Argos in your Playwright config

The Argos reporter seamlessly uploads screenshots and traces to Argos in real-time.

playwright.config.ts
import { defineConfig } from "@playwright/test";

export default defineConfig({
  // ... other configuration

  // Reporter to use
  reporter: [
    // Use "dot" reporter on CI, "list" otherwise (Playwright default).
    process.env.CI ? ["dot"] : ["list"],
    // Add Argos reporter.
    [
      "@argos-ci/playwright/reporter",
      {
        // Upload to Argos on CI only.
        uploadToArgos: !!process.env.CI,

        // Set your Argos token (required if not using GitHub Actions).
        token: "<YOUR-ARGOS-TOKEN>",
      },
    ],
  ],

  // Setup recording option to enable test debugging features.
  use: {
    // Collect trace when retrying the failed test.
    trace: 'on-first-retry',

    // Capture screenshot after each test failure.
    screenshot: "only-on-failure",
  },
});

Playwright's recording options facilitate the automated capture of screenshots upon test failures. Notably, these captured screenshots and traces are then automatically uploaded to Argos.

3. Take screenshots

Use argosScreenshot helper to capture stable screenshots in your E2E tests.

tests/example.spec.ts
import { test } from "@playwright/test";
import { argosScreenshot } from "@argos-ci/playwright";

test("screenshot homepage", async ({ page }) => {
  await page.goto("http://localhost:3000");
  await argosScreenshot(page, "homepage");
});

Tip: Check out our guides to screenshot multiple pages or capture multiple viewports.

Congratulations on installing Argos! 👏

After committing and pushing your changes, the Argos check status will appear on your pull request in GitHub (or GitLab).

Note: you need a reference build to compare your changes with. If you don't have one, builds will remain orphan until you run Argos on your reference branch.

You can now review changes of your app for each pull request, avoid visual bugs and merge with confidence. Welcome on board!
