import { $, expect } from '@wdio/globals'
import { render } from '@testing-library/vue'
import HelloWorld from '../../src/components/HelloWorld.vue'

describe('Component Testing', () => {
it('increments value on click', async () => {
const { getByText } = render(HelloWorld)
const btn = getByText('count is 0')

// transform into WebdriverIO element
const button = await $(btn)

// interact with element like a real user

await expect(button).toMatchInlineSnapshot(
"count is 2"

E2E and Unit / Component Testing in real Browser!

WebdriverIO is an all in one framework for your web app development. It enables you to run small and lightweight component tests as well as running e2e test scenarios in the browser or on a mobile device. This guarantees that you to do the testing in an environment used by your users.

It comes with smart selector strategies that simplify interacting e.g. with React components or running deep selector queries with nested shadow DOM trees. As interactions happen through a standardized automation protocol it is guaranteed they behave natively and aren't just JavaScript emulated.

Easy setup for web component testing with:

Watch Talks about WebdriverIO

The community around WebdriverIO is actively speaking on various user groups or conferences about specific topics around automated testing with WebdriverIO. Check out this talk on My favourite features of WebdriverIO by Julia Pottinger at Open Quality Conference.

There is also many YouTube Channels with useful tutorials by community members such as Klamping, Seventeenth Sep or Automation Bro.

Google Lighthouse Integration

WebdriverIO not only runs automation based on the WebDriver protocol, it also leverages native browser APIs to enable integrations to popular developer tools such as Chrome DevTools or Google Lighthouse. With the @wdio/devtools-service plugin you have access to commands for validating if you app is a valid PWA application as well as to commands for capturing frontend performance metrics such as `speedIndex` and others.

Integration to developer tools such as:

Chrome DevToolsGoogle LighthouseAxe Accessibility Engine

await browser.emulateDevice('iPhone X')
await browser.enablePerformanceAudits({
networkThrottling: 'Good 3G',
cacheEnabled: true,
formFactor: 'mobile'

// open application under test
await browser.url('https://localhost:3000')

expect(await browser.getMetrics().firstMeaningfulPaint)

const pwaCheckResult = await browser.checkPWA()
