Cypress Automation Training Course in Chennai

Cypress is a front-end testing tool for web applications built on JavaScript. Unlike Selenium, which runs outside the browser, Cypress runs directly in the browser, giving faster and more reliable results.

Cypress supports end-to-end (E2E) testing, integration testing, and some unit testing. It focuses mainly on testing UI flows like login, form validation, and navigation inside the browser.

Cypress commands are promise-like but auto-managed. You don’t use async/await or .then chaining often. Cypress executes steps sequentially and automatically waits for each to finish before proceeding.

Fixtures are external files (like JSON or CSV) that hold test data. You can load them in tests using cy.fixture('filename') to keep your test scripts clean and reusable.

describe('Login Test', () => { it('should login successfully', () => { cy.visit('/login'); cy.get('#email').type('user@test.com'); cy.get('#password').type('123456'); cy.get('button').click(); cy.contains('Welcome').should('be.visible'); }); });

The Test Runner is the visual UI where you can run your test scripts, see the commands executed step-by-step, inspect DOM elements, and debug failed tests easily.

Cypress is capable of intercepting and stubbing API requests through the use of cy.intercept(). This allows testing front-end behavior without depending on actual backend responses or external APIs.

Yes, Cypress supports responsive testing. You can set the viewport size using cy.viewport(width, height) or preset device names like cy.viewport('iphone-x').

Cypress only supports testing in Chrome-family and Electron browsers, doesn't support multiple tabs or native mobile apps, and runs inside the browser, which may not suit all backend-heavy applications.
