Gitlab CI Pipelines with playwright testing

Looking for some help with getting playwright tests running correctly in GitLab CI. I've got most of it up and running but need some confirmation/guidance on how to correctly setup the pipeline with nuxt (ssr:false) and running playwright correctly. I'm running in to some errors where the pages aren't loading and my tests are failing. Not sure if ti's to do with the speed of the CI getting the site running in time for playwright as it seems to always be my 1st test that fails.

Hi @Scripted Pixels. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- I apologize, but I don't have specific information about GitLab CI pipelines with Playwright testing for Nuxt applications in the provided knowledge sources. However, I can offer some general guidance based on the available information about Nuxt and Playwright testing: 1. For Nuxt applications with ssr: false, make sure you're properly building and serving your static site before running Playwright tests. The Nuxt configuration documentation mentions that setting ssr: false will generate pages with no content. 2. Regarding Playwright testing with Nuxt, you can use @nuxt/test-utils which provides built-in support for Playwright. The Testing in a Browser documentation explains how to set this up. 3. For your specific issue with pages not loading in time, you might want to consider adding a wait step or increasing timeouts in your tests. The Playwright test runner allows you to configure this. You can use the waitUntil: 'hydration' option when navigating to pages, as shown in this example:

   import { expect, test } from '@nuxt/test-utils/playwright'

   test('test', async ({ page, goto }) => {
     await goto('/', { waitUntil: 'hydration' })
     await expect(page.getByRole('heading')).toHaveText('Welcome to Playwright!')
   })

   import { expect, test } from '@nuxt/test-utils/playwright'

   test('test', async ({ page, goto }) => {
     await goto('/', { waitUntil: 'hydration' })
     await expect(page.getByRole('heading')).toHaveText('Welcome to Playwright!')
   })

4. Make sure you're properly setting up the Nuxt environment in your Playwright configuration. You can do this globally or per test file, as shown in the Testing in a Browser documentation. For specific GitLab CI configuration, you might need to ensure that your pipeline is correctly building the Nuxt application, serving it, and then running the Playwright tests. Unfortunately, the provided knowledge sources don't contain specific information about GitLab CI setup for this scenario. If you continue to face issues, you might want to check the Nuxt and Playwright documentation for more detailed troubleshooting steps, or consider reaching out to the Nuxt community forums for more specific help with your GitLab CI setup. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai can you show me the best way to run these tests in the pipeline for gitlab?

Let me check the knowledge base for you again. One moment! :books: ---------------------- I apologize, but I don't have specific information about running Nuxt and Playwright tests in GitLab CI pipelines from the provided knowledge sources. The documents don't contain details about GitLab CI configuration or best practices for running these tests in a GitLab pipeline. To provide an accurate and helpful answer, I would need access to GitLab-specific documentation or Nuxt-GitLab integration guides, which are not present in the given knowledge sources. If you're looking for general guidance on setting up Playwright tests with Nuxt, I can provide some information based on the available documentation. However, for GitLab CI-specific configurations, I recommend consulting GitLab's official documentation or seeking advice from the Nuxt or GitLab communities for the most up-to-date and accurate information. Is there anything specific about Nuxt and Playwright testing setup (without GitLab CI) that you'd like to know more about? I'd be happy to help with that based on the information available in the knowledge sources. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai can you show me how I should correctly wait for the page to load before each test & then continue with my tests

kapa.ai•3d ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- Certainly! I can show you how to properly wait for a page to load before running your tests using Playwright with Nuxt. Based on the information from the Testing in a Browser documentation, here's how you can achieve this: 1. First, make sure you're using the Nuxt-specific Playwright setup:

import { expect, test } from '@nuxt/test-utils/playwright'

import { expect, test } from '@nuxt/test-utils/playwright'

2. When navigating to a page, use the goto function with the waitUntil: 'hydration' option. This ensures that the page is fully loaded and hydrated before proceeding with the test:

test('my test', async ({ page, goto }) => {
  await goto('/', { waitUntil: 'hydration' })
  // Your test assertions go here
})

test('my test', async ({ page, goto }) => {
  await goto('/', { waitUntil: 'hydration' })
  // Your test assertions go here
})

Here's a complete example of how your test file might look:

import { expect, test } from '@nuxt/test-utils/playwright'

test('example test', async ({ page, goto }) => {
  // Navigate to the page and wait for it to be fully loaded and hydrated
  await goto('/', { waitUntil: 'hydration' })

  // Now you can perform your tests
  await expect(page.getByRole('heading')).toHaveText('Welcome to Nuxt!')

  // More test assertions...
})

import { expect, test } from '@nuxt/test-utils/playwright'

test('example test', async ({ page, goto }) => {
  // Navigate to the page and wait for it to be fully loaded and hydrated
  await goto('/', { waitUntil: 'hydration' })

  // Now you can perform your tests
  await expect(page.getByRole('heading')).toHaveText('Welcome to Nuxt!')

  // More test assertions...
})

This approach ensures that each test waits for the page to be fully loaded and hydrated before proceeding with the test assertions. The waitUntil: 'hydration' option is specifically useful for Nuxt applications as it waits for the hydration process to complete. If you need to navigate to different pages within your tests, you can use the same goto function with the waitUntil: 'hydration' option for each navigation:

test('multi-page test', async ({ page, goto }) => {
  await goto('/', { waitUntil: 'hydration' })
  // Test home page

  await goto('/about', { waitUntil: 'hydration' })
  // Test about page
})

test('multi-page test', async ({ page, goto }) => {
  await goto('/', { waitUntil: 'hydration' })
  // Test home page

  await goto('/about', { waitUntil: 'hydration' })
  // Test about page
})

This method should help ensure that your pages are fully loaded before your tests run, potentially resolving the issues you were facing with your first test failing due to timing problems. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai how does this look when I use the beforeEach

kapa.ai•3d ago

Let me check the knowledge base for you again. One moment! :books: ---------------------- To show you how to use beforeEach with Playwright tests in a Nuxt application, I'll refer to the Testing in a Browser documentation and adapt the example to include a beforeEach hook. Here's how it would look:

import { expect, test } from '@nuxt/test-utils/playwright'

test.describe('My Nuxt App Tests', () => {
  test.beforeEach(async ({ page, goto }) => {
    // Navigate to the home page before each test
    await goto('/', { waitUntil: 'hydration' })
  })

  test('home page test', async ({ page }) => {
    // The page is already loaded due to beforeEach
    await expect(page.getByRole('heading')).toHaveText('Welcome to Nuxt!')
  })

  test('another test', async ({ page }) => {
    // The page is already loaded due to beforeEach
    // You can perform other tests here
  })
})

import { expect, test } from '@nuxt/test-utils/playwright'

test.describe('My Nuxt App Tests', () => {
  test.beforeEach(async ({ page, goto }) => {
    // Navigate to the home page before each test
    await goto('/', { waitUntil: 'hydration' })
  })

  test('home page test', async ({ page }) => {
    // The page is already loaded due to beforeEach
    await expect(page.getByRole('heading')).toHaveText('Welcome to Nuxt!')
  })

  test('another test', async ({ page }) => {
    // The page is already loaded due to beforeEach
    // You can perform other tests here
  })
})

In this setup: 1. We use test.describe to group our tests. 2. Inside the describe block, we use test.beforeEach to set up the conditions that should be met before each test runs. 3. In the beforeEach hook, we navigate to the home page and wait for it to be fully loaded and hydrated. 4. Each individual test can then focus on its specific assertions without needing to handle navigation. This approach ensures that each test starts with a fresh, fully-loaded home page. If you need to test different pages, you can either: 1. Use goto within specific tests to navigate to other pages, or 2. Pass a parameter to beforeEach to determine which page to load. For example:

import { expect, test } from '@nuxt/test-utils/playwright'

test.describe('My Nuxt App Tests', () => {
  test.beforeEach(async ({ page, goto }, testInfo) => {
    const path = testInfo.title.includes('about') ? '/about' : '/'
    await goto(path, { waitUntil: 'hydration' })
  })
test('home page test', async ({ page }) => {
    await expect(page.getByRole('heading')).toHaveText('Welcome to Nuxt!')
  })

  test('about page test', async ({ page }) => {
    await expect(page.getByRole('heading')).toHaveText('About Us')
  })
})

import { expect, test } from '@nuxt/test-utils/playwright'

test.describe('My Nuxt App Tests', () => {
  test.beforeEach(async ({ page, goto }, testInfo) => {
    const path = testInfo.title.includes('about') ? '/about' : '/'
    await goto(path, { waitUntil: 'hydration' })
  })
test('home page test', async ({ page }) => {
    await expect(page.getByRole('heading')).toHaveText('Welcome to Nuxt!')
  })

  test('about page test', async ({ page }) => {
    await expect(page.getByRole('heading')).toHaveText('About Us')
  })
})

This setup allows you to reuse the waiting logic across all your tests while still providing flexibility for testing different pages. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
