Polling

Angular 19 frontend for the Polling application.

Pre-requisites

• Node.js 18+
• Firefox (used as the test browser)
• The Polling-API backend running locally or accessible via the configured apiUrl

Installation

npm install

Development server

ng serve

Navigate to http://localhost:4200/. The app reloads automatically on file changes.

Build

ng build

Build artifacts are output to the dist/ directory.

Running tests

Tests use Karma + Jasmine with Firefox (headless by default).

# Run all tests once (no watch)
npx ng test --watch=false

# Run tests in watch mode (reruns on file changes)
npx ng test

Test setup notes

• The test browser is FirefoxHeadless (configured in karma.conf.js). Firefox must be installed.
• Components are Angular 19 standalone — specs use imports: [ComponentName] (not declarations).
• HTTP services use HttpClientTestingModule; standalone component specs use provideHttpClient() + provideHttpClientTesting().
• StorageService tests mock sessionStorage via Object.defineProperty for Firefox compatibility.
• Navigation in production code uses Angular Router (not window.location) to keep tests framework-friendly.
