Playwright VS nightwatch

In this tutorial, our main focus will be on Playwright web scraping. So what is Playwright? It’s a handy framework created by Microsoft. It's known for making web interactions more streamlined and works reliably with all the latest browsers like WebKit, Chromium, and Firefox. You can also run tests in headless or headed mode and emulate native mobile environments like Google Chrome for Android and Mobile Safari.

// playwright.config.ts import { defineConfig } from "@playwright/test"; /** * See https://playwright.dev/docs/test-configuration. */ export default defineConfig({ testDir: "./src/pages", reporter: "list", use: { baseURL: "http://localhost:5432/", }, timeout: process.env.CI ? 10000 : 4000, // ... more options });

Issues with Playwright

Fast and reliable end-to-end testing for modern web apps | Playwright

This means you cannot place test files outside of this directory, which was brought up as a question on Github some time ago. Initially, I thought it would be nice to add another folder in the repo called "scripts", but Playwright does not allow multiple testDir values.

4.Playwright: Playwright is a browser automation library by Microsoft. Key Features: Supports Chromium, Firefox, and WebKit. Provides cross-browser testing capabilities. Allows automating web, mobile, and desktop applications

HTML to PDF conversion is a common requirement in modern web applications. It allows users to save web pages, reports, and other content in a format that is easy to share and print. There are many libraries and services available for converting HTML to PDF, each with its own strengths and weaknesses. In this article, we will compare some of the most popular HTML to PDF renderers in Node.js, including Puppeteer, Playwright, node-html-pdf, and Onedoc.

Playwright seems to be a superior library for working with headless browsers than Puppeteer, but I will go with Puppeteer.

6.NightwatchJS: NightwatchJS is a Node.js-based end-to-end testing framework. Key Features: Simplifies writing test scripts using a simple syntax. Supports parallel test execution. Integrates with Selenium WebDriver for cross-browser testing

NightWatchJS

I have shown you the examples of using selectors in the Google Chrome dev tools, but the idea is similar when you write your automation scripts. I will use the Nightwatch testing framework to write the following snippets which will navigate to some webpage, wait to ensure that an interactive element has appeared in the DOM, and finally click on it. If you want to learn using Javascript with Nightwatch framework for your automated tests, you can start with our guide to this.

The reason for this behavior is thoroughly explained in Understanding the Command Queue Nightwatch.js GitHub wiki (it is a long read but it’s worth it). In this section, we will not look in such detail, this is going to be a summary of sorts. By the way, this command queue example can be found in Loadero’s public GitHub examples repository here.

Nightwatch.js is a popular open-source, Selenium JavaScript-based test automation framework for automating browser-based web applications and websites. It is written in Node.js runtime and uses the W3C WebDriver API (formerly Selenium WebDriver) for interacting with various browsers to perform commands and assertions on DOM elements.

For Firefox-specific options (like command-line args and browser about:config prefs), the property to use is moz:firefoxOptions. That is shipping in the latest default nightwatch.conf.js file, as is the parallel goog:chromeOptions for chromedriver. But if you've got a legacy configuration file—like I did—you'll want to update the old chromeOptions property, too.
