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
Prerequisite:
- ESLint is installed (
npm i eslint --save-dev
)
- Install
eslint-plugin-ui-testing
:
npm i eslint-plugin-ui-testing --save-dev
- Add the
ui-testing
plugin to the.eslintrc
configuration file.
{
"plugins": ["ui-testing"]
}
- 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"]
}
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
(underUsage
), 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.
