Describe the bug

I just installed playwright version 1.12 to try out the new test runner but I am consistently getting Please install @playwright/test package to use Playwright Test. no matter how many times I do yarn add --dev @playwright/test.

You don't need playwright when using @playwright/test:

yarn init -y
yarn add --dev @playwright/test
npx playwright test

Had the same issue, because previous beta versions of @playwright/test did require playwright.

Solution:

• npm rm playwright
• npm install @playwright/test -D

Then it works.

[cyrilletuzi]

Note/question: for projects using Playwright for both unit tests and e2e tests, could this be a problem? or is @playwright/test-only the way to go in this scenario?

[mpuertao]

In my case,

• Delete playwright,
• Install @playwright/test
• Reinstall playwright.

Success!!!

You don't need playwright when using @playwright/test:

yarn init -y
yarn add --dev @playwright/test
npx playwright test

Yep. This worked.

I ran into this issue because I had test in my .yarnclean file. Yarn removed the lib/test folder and the entire node_modules/@playright/test folder because of this 🤦

I fixed by adding this to .yarnclean:

!@playwright/test/**

[mrienstra]

The solutions above did not work for me, I couldn't figure out how to get past

Please install @playwright/test package to use Playwright Test.
  npm install -D @playwright/test

... when running npx playwright test.

Resolved by running yarn playwright test instead of npx playwright test.

See also #8495 for another snag one may encounter when using Yarn 2 PnP and @playwright/test (will likely be fixed in the next release).

I've been trying everything I can think of to get testing to work in an Azure Pipeline.

My YAML:

resources:
  containers:
  - container: playwright
    image: mcr.microsoft.com/playwright:focal

  repositories:
  - repository: self
    type: git
    ref: refs/heads/develop

jobs:
- job: e2e_testing
  container: playwright
  displayName: E2E Testing

  pool:
    vmImage: ubuntu-latest

  steps:
  - checkout: self

  - script: |
      yarn
      npx playwright test
    displayName: 'Run test'

  - task: PublishTestResults@2
    inputs:
      testResultsFormat: 'JUnit'
      testRunTitle: 'Test Report'
    displayName: 'Publish Reports'

but I get...

Please install @playwright/test package to use Playwright Test.
  npm install -D @playwright/test
##[error]Bash exited with code '1'.

If I try to use yarn playwright test, then I get...

yarn run v1.22.11
$ playwright test
/bin/sh: 1: playwright: not found
error Command failed with exit code 127.

What is the magic combination to make this work??

[mrienstra]

@nathanchase, does yarn playwright test work locally? Might be hard to diagnose without knowing more.

Yes, works fine locally.

[mrienstra]

@nathanchase, stab in the dark, but maybe you need to run yarn playwright install in CI?
