Playwright Framework

This is a wrapper/meta framework around Playwright - an end-to-end testing framework. This is a central configuration repository which allows us to update settings and config for all our projects.

[!NOTE] More documentation can be found in the docs folder

Naming Conventions

• *.unit.ts - These are unit tests and should not open the browser - they are only run by the first device
• *.spec.ts - These should test functionality and open the browser - they are only run by the first device
• *.test.ts - These should be used for end-to-end testing and are run by all the devices specified

Get Started

Install

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

Playwright Config

Create a playwright.config.ts with the following contents:

import { defineConfig } from '@playwright/test';

const config = require('@liquidlight/playwright-framework')([
    {
        label: 'Site name',
        envs: {
            local: 'https://liquidlight.ddev.site',
            production: 'https://www.liquidlight.co.uk',
        },
        project: {
            testDir: './path/to/site/files/'
        }
    }
]);

• A Playwright project is made for each default device (e.g. the above config will make two PLaywright Projects)
• Everything passed into the project object inside the site will be passed directly to each project
• If you pass devices as an array of strings, a project will be made per device (or you can not use any device by passing an empty array)

More details on how the configuration works can be found in the docs. If you are running a TYPO3 site, it's worth checking out the Liquid Light Playwright Framework TYPO3 documentation.

[!TIP] By setting local & production domains (and other), the framework can use these domains for your tests without needing to specify the full URL

Your first test

In the testDir specified, create a new file (e.g. newtest.test.ts)with the following contents. This will test the accessibility of your homepage.

import { test } from '@playwright/test';
import { assertPageIsAccessible } from '@liquidlight/playwright-framework/tests';

/**
 * Ensure our base page template is accessible
 */
test('"Tests" page is accessible', async ({ page }, testInfo) => {
    await page.goto('/');

    await assertPageIsAccessible(page, testInfo);
});

Run the test

./node_modules/.bin/playwright test

By default, this will use the local environment (unless that domain hasn't been specified, then it uses production).

Change the environment

If you wish to use the production domain (or any other domain set in the envs object) you can by modifying the PLAYWRIGHT_ENV var or passing in an --env flag

For example:

PLAYWRIGHT_ENV=staging ./node_modules/.bin/playwright test

or

./node_modules/.bin/playwright test --env=staging

.gitignore

Add the following to your .gitignore file:

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

Notes

• The /testbed/ is optional, see the testbed docs for more info
• The *test.ts-snapshots/ is option, depending if you want to commit your snapshots/screenshots

Scripts

If you wish to set up npm run test, you can add the following to your 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"
  },
}

Notes

• 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

Releasing

When it comes to releasing, run the following:

1. npx eslint . and npx eslint . --fix
2. npm run build
3. Update the version number in package.json
4. npm update & commit result
5. git tag [version]
6. git push origin main --tags
7. npm publish
