Overview

Configuration pattern for registering component testing plugins and Vite/Webpack dev server settings in Nightwatch.js.

Description

The component testing configuration adds the plugins array and optional vite_dev_server settings to nightwatch.conf.js. The plugins array lists installed component testing packages. The dev server configuration controls auto-start behavior and port assignment. This is a user-created configuration file; no canonical component config exists in the Nightwatch repository.

Usage

Add the plugins array and dev server settings to nightwatch.conf.js after installing the component testing plugin.

Code Reference

Source Location

• Repository: nightwatch
• File: nightwatch.conf.js (user-created configuration file)

Signature

  // Register component testing plugins

  // Vite dev server configuration
  vite_dev_server: {
    start_vite: true,  // Auto-start Vite dev server
    port: 5173         // Dev server port
  },

  // Other standard Nightwatch settings...
};
