Test Framework Layers

• Fixtures Layer: Contains JSON or other files with test data (e.g., user.json). Loaded using cy.fixture().
• Test Specs Layer: Test files in cypress/e2e/ that use cy.fixture() to load data and run tests.
• Support Layer: Custom commands and reusable utilities to keep tests clean.
• Configuration Layer: cypress.config.js manages environment settings, base URLs, and test options.

Configuration Patterns

Use cypress.config.js to define base URLs and environment variables.

    // cypress.config.js
    import { defineConfig } from 'cypress'

    export default defineConfig({
      e2e: {
        baseUrl: 'https://example.com',
        env: {
          username: 'testuser',
          password: 'password123'
        },
        setupNodeEvents(on, config) {
          // implement node event listeners here
        }
      }
    })
    

Fixtures are stored as JSON files in cypress/fixtures/. Load them in tests with cy.fixture('user').then((user) => {...}).

Test Reporting and CI/CD Integration

• Use built-in Cypress test runner for interactive reports.
• Integrate with mochawesome reporter for detailed HTML reports.
• Configure CI pipelines (GitHub Actions, Jenkins) to run npx cypress run and collect reports.
• Store test artifacts like screenshots and videos for failed tests.

Best Practices for Using cy.fixture()

• Keep fixture files small and focused on specific test data sets.
• Use descriptive file names for fixtures to clarify their purpose.
• Load fixtures in beforeEach() hooks to reuse data across tests.
• Avoid hardcoding test data inside test specs; use fixtures instead.
• Combine fixtures with environment variables for flexible test configurations.

Self Check Question

Where in this folder structure would you add a new fixture file for storing login credentials?

Key Result

Use fixtures folder to store test data files and load them in tests with cy.fixture() for clean, reusable data-driven tests.
