ESLint Plugin Playwright

ESLint plugin for Playwright.

Installation

npm

npm install -D eslint-plugin-playwright

Yarn

yarn add -D eslint-plugin-playwright

pnpm

pnpm add -D eslint-plugin-playwright

Usage

The recommended setup is to use the files field to target only Playwright test files. In the examples below, this is done by targeting files in the tests directory and only applying the Playwright rules to those files. In your project, you may need to change the files field to match your Playwright test file patterns.

Flat config (eslint.config.js)

import playwright from 'eslint-plugin-playwright'

export default [
  {
    ...playwright.configs['flat/recommended'],
    files: ['tests/**'],
    rules: {
      ...playwright.configs['flat/recommended'].rules,
      // Customize Playwright rules
      // ...
    },
  },
]

Legacy config (.eslintrc)

{
  "overrides": [
    {
      "files": "tests/**",
      "extends": "plugin:playwright/recommended"
    }
  ]
}

Settings

Aliased Playwright Globals

If you import Playwright globals (e.g. test, expect) with a custom name, you can configure this plugin to be aware of these additional names.

{
  "settings": {
    "playwright": {
      "globalAliases": {
        "test": ["myTest"],
        "expect": ["myExpect"]
      }
    }
  }
}

Custom Messages

You can customize the error messages for rules using the settings.playwright.messages property. This is useful if you would like to increase the verbosity of error messages or provide additional context.

Only the message ids you define in this setting will be overridden, so any other messages will use the default message defined by the plugin.

{
  "settings": {
    "playwright": {
      "messages": {
        "conditionalExpect": "Avoid conditional expects as they can lead to false positives"
      }
    }
  }
}
