Lessons Learned - Run Single Test File

Run single file with test bookstore.test.js. This works, but note, that expect cannot be used because it requires test module.

const { chromium } = require("playwright");

describe(`UI tests for bookstore using playwright`, () => {
  jest.setTimeout(10000);
  let browser = null;
  ...

npm test -- bookstore

Run all test in test folder

npm test

This does not work for script third.js, because file name does not include test suffix:

▶ npm test -- third

> playwright-demo-wywm@1.0.0 test
> jest "third"

No tests found, exiting with code 1

This does not work.

Install playwright/test

npm i -D @playwright/test

const { test, expect } = require('@playwright/test');


describe(`UI tests for bookstore using playwright`, () => {
  jest.setTimeout(10000);
  let browser = null;
  let page = null;

pm test -- bookstore3   

> playwright-demo-wywm@1.0.0 test
> jest "bookstore3"

 FAIL  tests/bookstore3.spec.js
  ● Test suite failed to run

    Playwright Test needs to be invoked via 'npx playwright test' and excluded from Jest test runs.
    Creating one directory for Playwright tests and one for Jest is the recommended way of doing it.
    See https://playwright.dev/docs/intro for more information about Playwright Test.

Instead, use this to run test

npx playwright test tests/bookstore.test.js
