Playwright VS Cypress

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.

Playwright is a Node.js library for automating browsers. It allows you to write scripts to interact with web pages, just like a real user would. You can use it to fill out forms, click buttons, and navigate between pages. It is most commonly used for end-to-end testing of the code-base, but it's also a great tool for monitoring continuously.

I tend to agree. An example of how it can be net-zero gain is in this screenshot[1]. To have something maintainable, you have to do your own refactoring pass on the generated code. At that point, it's not much effort to write the test yourself than it is to refactor all of the redundancies.

If you ever find that you need to automate some browsing and Selenium comes to your mind, banish that thought! :)

Do yourself a favour, use Playwright instead.

It's a headless browser that's both faster and less flaky than Selenium.

Playwright is a relatively new but powerful node library for browser automation. Developed by Microsoft, it enables cross-browser web automation that is ever-reliable for end-to-end testing. Playwright is compatible with all modern web browsers, including Chrome, Firefox, and Safari, and offers capabilities for both headless and non-headless browser testing.

Hah yeah that's confusing.

https://playwright.dev/python/docs/intro is actually the documentation for pytest-playwright - their pytest plugin.

I just filed an issue pointing out that this is confusing. https://github.com/microsoft/playwright/issues/29579

Playwright is the fastest growing web testing framework. Playwright enables end-to-end (E2E) tests to be created by synthetically driving a headless browser session and enabling assertions to verify the system performs as expected. With Playwright traces, you can review a test after the script has run and identify exactly what occurred.

In this blog post, we'll explore a Cypress test that replicates this scenario, utilizing the powerful intercept command to manipulate network requests and responses.

Recently I came across this issue while triaging some issues at Cypress. (Shout out to MattiaMalandrone for creating an issue with clear instructions for how to reproduce). After quickly replicating the issue I sought after a solution which ultimately inspired me to write this article.

While similar to Puppeteer, Cypress, and Selenium, there are some differences. Let’s find out what they are.

Cypress Release Notes

Next, the values ​​of the command keys set the commands to launch Cypress in browsers with the given names. It is worth noting here that in the e2e-firefox service, the command was supplemented by a configuration change due to an open issue with recording video when using the Firefox browser in Cypress.

Synpress is e2e testing framework based on Playwright and Cypress with support for MetaMask.
