How do I set up environment and install cypress?

# Prerequisites - Install Node.js (v18 or later, check `.nvmrc` in repo for exact). ## Steps 1. Create a new directory: ```bash mkdir cypress-learning cd cypress-learning npm init -y ``` 2. Install Cypress (v15.11.0 latest): ```bash npm install cypress --save-dev ``` 3. Open Cypress Test Runner: ```bash npx cypress open ``` This downloads browsers and opens the app. Select E2E Testing, create a spec file.

How do I write and run your first e2e test?

## Create First Test In `cypress/e2e/` create `first.cy.js`: ```javascript describe('My First Test', () => { it('Visits Kitchen Sink and interacts', () => { cy.visit('https://example.cypress.io'); cy.contains('type').click(); cy.url().should('include', '/commands/actions'); cy.get('.action-email') .type('fake@email.com'); cy.get('.action-email') .should('have.value', 'fake@email.com'); }); }); ``` Save file – test runs automatically in Test Runner. Watch Command Log.

How do I master core commands and assertions?

## Key Concepts - **Querying**: `cy.get('.selector')`, `cy.contains('text')` - **Actions**: `.click()`, `.type('text')` - **Assertions**: `.should('be.visible')`, `.should('have.value', 'x')` - **Chaining**: Commands queue asynchronously. ## Practice Extend test: ```javascript cy.get('[data-cy="submit"]').click(); cy.get('.success').should('contain', 'Email sent'); ``` Explore [Commands docs](https://docs.cypress.io/api/table-of-contents). 74

How do I organize tests with fixtures and hooks?

## Fixtures Create `cypress/fixtures/users.json`: ```json {"email": "user@example.com"} ``` Use in test: ```javascript cy.fixture('users.json').then((user) => { cy.get('.email').type(user.email); }); ``` ## Hooks ```javascript beforeEach(() => { cy.visit('/'); }); afterEach(() => { cy.screenshot(); }); ``` Run headlessly: `npx cypress run`.

How do I advanced: ci integration and best practices?

## CI with GitHub Actions `.github/workflows/cypress.yml`: ```yaml name: Cypress Tests on: [push] jobs: cypress-run: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - uses: cypress-io/github-action@v6 ``` ## Best Practices - Use aliases: `cy.get('form').as('form')` - Custom commands in `cypress/support/commands.js` - Study real apps in learn.cypress.io courses.
