A dependable first project is small: open a page, locate an element with a stable selector, perform one action, assert the visible result, and close the browser.
This quickstart uses JavaScript and Playwright for that workflow, then shows how Selenium and Puppeteer differ, how to prepare local and CI environments, and how to diagnose the failures beginners encounter most often.
Choose a framework before installing anything
No framework is universally best. Match the tool to your language, browser requirements, test runner, and existing team stack.
| Framework | Good default when | Important setup detail |
|---|---|---|
| Playwright | You want one cohesive test setup across Chromium, Firefox, and WebKit, with locator-based actions and web-first assertions. | Install browser binaries that match the Playwright package version. |
| Selenium | Your organization already uses WebDriver bindings, Grid, or a language with a mature Selenium ecosystem. | Choose a language binding, browser, and driver; Selenium Manager is the default driver/browser management path in current bindings. |
| Puppeteer | You want a direct JavaScript API for launching or connecting to a browser and controlling pages. | Pin the package version and use its launch, page, navigation, interaction, inspection, and close workflow. |
Playwright documents projects for Chromium, Firefox, WebKit, branded Chrome or Edge channels, and device emulation. Selenium targets major browsers through WebDriver implementations and can allocate browsers across machines with Grid. Puppeteer’s current getting-started page identifies version 25.12.0; check the package documentation when copying examples because versions change.

What you need for a first run
- A supported runtime such as Node.js for this JavaScript example.
- The framework package and its matching browser binaries (Playwright), or a browser and driver path (Selenium).
- Operating-system libraries when a headless browser requires them in Linux or CI.
- A test page and a selector that is unlikely to change.
Keep your first script independent of your production application. A public page or a local fixture lets you separate framework problems from application bugs.
Build a first Playwright test in JavaScript
1. Create the project
- Make a directory and initialize npm:
mkdir browser-quickstart && cd browser-quickstart && npm init -y. - Install Playwright Test:
npm install -D @playwright/test. - Install the default browser binaries:
npx playwright install. - On a Linux machine missing shared libraries, install Chromium dependencies with
npx playwright install-deps chromium(use the dependency command appropriate to your selected engine).
Playwright releases target specific browser versions. After upgrading the package, run the install command again so the binaries are compatible.
2. Write a small, observable test
Create tests/example.spec.js:
import { test, expect } from '@playwright/test';
test('search returns a result', async ({ page }) => {
await page.goto('https://www.google.com', { waitUntil: 'domcontentloaded' });
const search = page.getByRole('combobox', { name: /search/i });
await search.fill('Playwright browser automation');
await search.press('Enter');
await expect(page).toHaveTitle(/Playwright/i);
});The example uses a role and accessible name rather than a fragile CSS path. The assertion checks a user-visible outcome: the page title after submitting. On a site whose consent dialog appears first, handle that dialog with a locator before filling the search field, or use a test fixture that disables it.
3. Run and inspect it
- Run headless:
npx playwright test. - Watch the browser while debugging:
npx playwright test --headed. - Open the HTML report after a failure:
npx playwright show-report.
Playwright actions wait for elements to become actionable, and web-first assertions wait for the expected state. Prefer those behaviors to arbitrary sleeps such as waitForTimeout(5000). A fixed delay may pass on your laptop and fail under a slower CI runner.

Use stable locators and assertions
Locator choices
- Preferred:
getByRolewith an accessible name,getByLabelfor form controls, andgetByTextwhen the visible wording is the contract. - Useful fallback: a dedicated
data-testidattribute agreed with developers. - Last resort: long CSS or XPath chains tied to layout or generated class names.
If a locator matches multiple elements, narrow it with a name, filter, or container. Do not “fix” ambiguity by selecting the first match unless position is genuinely part of the requirement.
Assertions that explain the requirement
Assert the state a user or another system relies on: a heading is visible, a URL has changed, a confirmation message appears, a row contains expected text, or a download exists. A screenshot alone is useful evidence but is not a substitute for an assertion.
Playwright browser and project configuration
A configuration file can run the same test against multiple engines:
import { defineConfig, devices } from '@playwright/test';
export default defineConfig({
projects: [
{ name: 'chromium', use: { ...devices['Desktop Chrome'] } },
{ name: 'firefox', use: { ...devices['Desktop Firefox'] } },
{ name: 'webkit', use: { ...devices['Desktop Safari'] } }
]
});Run one project with npx playwright test --project=webkit. Use branded Chrome or Edge channels only when your compatibility requirement calls for them; otherwise the versioned Playwright browsers make runs more reproducible.

Equivalent setup paths for Selenium and Puppeteer
Selenium
Selenium’s first-script path has three explicit pieces: a language binding, a browser, and a driver implementation. Install the binding for your language, install or provide the browser, and let current Selenium bindings use Selenium Manager for driver and browser management by default. A minimal Python flow is:
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
with webdriver.Chrome() as driver:
driver.get("https://www.google.com")
box = driver.find_element(By.NAME, "q")
box.send_keys("Selenium browser automation", Keys.ENTER)
assert "Selenium" in driver.titleWhen you need parallel allocation across machines, Selenium Grid is the scaling component; it is not required for a first local script. Selenium IDE is a record/playback extension, also optional.
Puppeteer
Puppeteer’s direct workflow is launch or connect, create a page, navigate, set a viewport, find an element, interact, inspect a result, and close:
import puppeteer from 'puppeteer';
const browser = await puppeteer.launch({ headless: true });
const page = await browser.newPage();
await page.setViewport({ width: 1280, height: 800 });
await page.goto('https://www.google.com', { waitUntil: 'domcontentloaded' });
await page.locator('textarea[name="q"], input[name="q"]').fill('Puppeteer automation');
await page.keyboard.press('Enter');
await page.waitForNavigation({ waitUntil: 'domcontentloaded' }).catch(() => {});
console.log(await page.title());
await browser.close();Confirm the Puppeteer version before using an example; the current getting-started documentation lists 25.12.0, while APIs can change between releases.

Make the script reliable in CI
- Pin dependencies: commit the lockfile and upgrade framework and browser binaries together.
- Install OS dependencies: use the Playwright dependency command or the equivalent packages in your CI image.
- Control secrets: pass credentials through environment variables or a secret store, never source files committed to Git.
- Capture evidence: enable traces, screenshots, or video only where they help diagnose failures; retain the HTML report for failed runs.
- Isolate data: use a test account and reset or seed state so one run does not depend on another.
- Set realistic timeouts: use framework timeouts and network-aware waits, not large global sleeps.
- Check browser differences: run the engines your users require; do not assume Chromium behavior proves WebKit or Firefox behavior.
Troubleshooting common first-run failures
“Executable doesn’t exist” or browser launch failure
Cause: the browser binary was not installed, or it does not match the package. Run npx playwright install after installing or upgrading Playwright. In Linux CI, run npx playwright install-deps chromium (or the selected engine) and verify the base image supports the required libraries.
Driver or session errors in Selenium
Cause: a missing, incompatible, or inaccessible driver/browser. Confirm the binding version, browser version, and Selenium Manager output. If your organization manages drivers centrally, provide the approved driver path instead of mixing it with an unmanaged copy.
Locator found zero or multiple elements
Cause: the selector is tied to changing markup, the page is on a different state, or a consent dialog covers the control. Inspect the accessible role and name, add a stable test ID, and handle the dialog explicitly. Avoid silently choosing the first match.
Timeout waiting for an element or assertion
Cause: navigation has not reached the expected state, the application made a failed request, or the assertion describes the wrong outcome. Run headed, inspect the report or trace, and assert a specific visible state. Replace fixed sleeps with locator actions and web-first assertions.

Passes locally but fails in CI
Compare runtime and package lockfiles, browser versions, OS dependencies, viewport, timezone, locale, network access, and test data. Reproduce with the same container or image locally, then add diagnostics before increasing timeouts.
Or skip the browser setup
If your goal is a clean image or PDF of a URL rather than an interaction test, ScreenshotNeo provides a single-call website screenshot API. It accepts consent banners before capture and removes more than 60 known consent platforms, newsletter popups, and chat widgets; each step can be turned off. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed, and response headers identify the page verdict and billing status.
See the full parameter reference in the ScreenshotNeo docs. A minimal cURL capture is:
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpFor the same endpoint in Python:
import requests
r = requests.get("https://api.screenshotneo.com/v1/shot", params={"access_key": "YOUR_API_KEY", "url": "https://stripe.com"}, timeout=90)
open("shot.webp", "wb").write(r.content)And Node.js:
const q = new URLSearchParams({ access_key: 'YOUR_API_KEY', url: 'https://stripe.com' });
const res = await fetch(`https://api.screenshotneo.com/v1/shot?${q}`);ScreenshotNeo also offers an MCP server with take_screenshot, get_page_info, and capture_pdf tools for Claude, Cursor, and other MCP clients. It supports full-page and element captures, device and retina settings, dark mode, PDF options, custom CSS or JavaScript, clicks, waits, request blocking, headers, cookies, user agents, authorization, timezone and geolocation, transparent backgrounds, resizing, chosen cache TTLs, signed links, asynchronous webhooks, bulk capture of up to 100 URLs per call, usage reporting, and an OpenAPI specification. Every feature is on every plan: 1,000 shots per month free with no card, then $5 for 3,000, $15 for 15,000, $39 for 60,000, $99 for 250,000, or $249 for 1,000,000; yearly billing gives two months free.

Frequently Asked Questions
Should I learn Selenium before Playwright?
No. Start with the framework that matches your project and language. Concepts such as locators, waits, assertions, isolation, and diagnostics transfer between tools.
Can these frameworks automate logged-in pages?
Yes, when you provide an authorized test account or saved session through the framework’s supported authentication facilities. Keep credentials out of source control and respect the site’s permission and terms.
Do I need browser automation for every screenshot task?
No. Use an automation framework when you must interact with a page and verify behavior. Use a screenshot API when you need repeatable rendering, image or PDF output, or batch capture without maintaining browser setup.
