eslint-plugin-ui-testing

ESLint plugin that helps following best practices when writing UI tests. It supports the following automation tools (in alphabetical order):

• Cypress
• Playwright
• Puppeteer
• TestCafe
• WebdriverIO

Usage

Prerequisite:

• ESLint is installed (npm i eslint --save-dev)

1. Install eslint-plugin-ui-testing:

npm i eslint-plugin-ui-testing --save-dev

2. Add the ui-testing plugin to the .eslintrc configuration file.

{
    "plugins": ["ui-testing"]
}

3. Configure the rules as follows by using the recommended ruleset per automation tool. Choose one from:

• plugin:ui-testing/cypress
• plugin:ui-testing/playwright
• plugin:ui-testing/puppeteer
• plugin:ui-testing/testcafe
• plugin:ui-testing/webdriverio

Example:

{
    "extends": ["plugin:ui-testing/webdriverio"]
}

Customization

You can customize specific rules in the .eslintrc configuration file.

{
    "rules": {
        "ui-testing/no-disabled-tests": "error", // default = warn
        "ui-testing/no-css-page-layout-selector": ["warn", "webdriverio"] // default = error
    }
}

• In case you are using a recommended ruleset as described in step 3 (under Usage), then these customized rules will override the default.
• It is also possible to omit the recommended ruleset and just set each rule specifically as above.
