Install

First, install the NPM module

npm i @liquidlight/playwright-framework -D --save

Create configuration

Create a playwright.config.ts for your playwright configuration and include the configuration function from the framework

import { defineConfig, configuration } from '@liquidlight/playwright-framework';

export default defineConfig(
	configuration({
		hosts: [
			{
				local: 'https://local.ddev.site/',
				production: 'https://www.livedomain.com/',
			}
		]
	})
);

The hosts configuration is there for the dynamic host switching - if you don’t wish to use this functionality you can remove the key

If your website runs on TYPO3, the host data can be gathered from the site config by using the typo3site function

Create a test

Create a test with the suffix of .unit.ts, .spec.ts or .test.ts following the Playwright “Writing Tests” documentation.

The only difference is you need to use the test and expect function from this framework instead of the default Playwright ones

import { test, expect } from '@liquidlight/playwright-framework';

.gitignore

Add the following to you .gitignore file

# Playwright Tests
/test-results/
/playwright-report/
/blob-report/
/playwright/.cache/
*.ts-snapshots/

If you wish to commit your Visual Regression results, then remove the *.ts-snapshots/ line

Run the test

You can run Playwright tests using the default npx runner.

npx playwright test

package.json scripts

However, for consistency and quick set-up, we prefer to add the following to the scripts block in package.json

{
	"scripts": {
		"test": "playwright test --grep-invert @vr",
		"test:vr": "playwright test --grep @vr",
		"test:update": "playwright test --update-snapshots --grep @snapshot",
		"test:open": "monocart show-report test-results/report.html"
	}
}

• The @vr stands for visual regression - if you tag any visual regression tests with this, it can save you from running them every time
• The test:update will inly update jobs tagged with @snapshot
• Utilise npx playwright codegen to help generate tests
