Understanding Playwright and Jest: A Strategic Guide for Effective Testing | by Joe Gray | Medium
December 5, 2023 - In summary, if you seek a straightforward JavaScript testing framework that combines simplicity with advanced features like effortless mocking, Jest emerges as a compelling solution. Unlike traditional methods of sending HTTP requests, Playwright operates directly in the WebSocket, utilizing the DevTools Protocol for Chrome and implementing its protocol for Firefox and WebKit.

r/QualityAssurance on Reddit: Jest vs Playwright
October 27, 2021 -
Hi everyone! I'm in charge of deciding which automation frameworks we should use at our company. For QA, I want them to use Playwright Test Runner + Playwright, esp since they have webkit (and a lot of our users use both Chrome and Safari), but our eng team already uses Jest for all of their unit tests.
Would it be better to do Jest + Playwright (to remain consistent with the rest of eng team) or do Playwright Test Runner + Playwright (since it's already similar to Jest and does a lot more than Jest from a QA's perspective)?
And if we should do the latter, then should we just let the eng team continue with Jest? I'm just not sure what to do so if anyone can give some advice about this, that would be great! Thank you!

Hard for me to say without more details but let me point out that the Jest-Playwright library recommends to use Playwright. https://github.com/playwright-community/jest-playwright

Go playwright test runner, which really is a wrapper over jest. You get videos, retry, tracing without having to go to other packages. Quicker ROI.

December 4, 2024 - When Playwright announced component testing I started to get excited. The promise was to write tests just like with Jest and Testing Library, but have them run inside a real browser, instead of some fake DOM.

May 28, 2020 - It gives you out of the box the ability to focus a single test, providing a formatted output or a whole suite for common assertions called expect in Jest. The framework is maintained by Facebook and is mostly the default choice for writing frontend or backend unit tests in the JavaScript ecosystem. It's framework agnostic and by that, you can test with it e.g. your express backend or your React components. The way how you should integrate Playwright into your project depends on your needs.

Cross-Browser Testing with Jest Playwright | by Vinicius Gabriel Cabral Paulino | Medium
May 15, 2021 - I’ve started playing around with Playwright in the past months, and cross-browser tests are something that people commonly look for. Of course, there are several different ways to achieve that, there are some testing frameworks that can be used. After browsing I’ve found the Jest Playwright, which provides a very easy way to run your tests using Jest and Playwright.

I reckon that what you want to do is to run tests that are generated using playwright codegen with Jest.
However, this does not seem to be possible: The tests are generated with import { test, expect } from '@playwright/test' at the top, and this is the module that throws the error. The tests that are generated with Playwright use the API from this module, and this is slightly different than the one from Jest. (It gets fixtures as parameters).
If you use the implementation from Playwright (for instance by mocking away the throwIfRunningInsideJest function), it still won't work because then the tests won't be registered in the Jest test runner.

If you have a different extension for your jest tests vs your playwright tests, excluding is what solved this for me.
For example, I have .test.js for jest and .spec.js for playwright. In jest config, I added modulePathIgnorePatterns: ["spec.js"], and it solved the issue.

June 19, 2023 - We are having this problem only recently. When we added playwright we put the config at the root of our monorepo and just added all our tests into an e2e-tests folder. Then adding "e2e-tests" to our testPathIgnorePatterns setting in Jest made sure they never ran.
