How do you perform E2E testing using Protractor?

Short answer: Protractor is built on WebDriverJS for Angular E2E tests. Write test specs using Jasmine syntax. Run tests against a running Angular app. Example test: describe('App E2E Test', () => { it('should display welcome message', () => { browser.get('/'); expect(element(by.css('h1')).getText()).toEqual('Welcome'); }); }); Run with: ng e2e

Real-world example (ShopNest)

ShopNest admin can be built in Angular with modules/components, services for API calls, and reactive forms for product edit.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
