When working with network connections and HTTP requests, implement flexible configuration patterns and robust response handling to prevent flaky behavior and ensure compatibility across environments.

For network configurations:

  • Always specify complete endpoint information including port numbers
  • Use environment variables for configurable network settings
// Instead of:
baseUrl: 'http://localhost', // May cause connection issues

// Use:
baseUrl: process.env.CYPRESS_BASE_URL || 'http://localhost:80', // Configurable with explicit port

For HTTP response handling:

  • Accept all valid status codes for a given scenario rather than requiring a specific one
  • Consider cache-related status codes (like 304) alongside traditional success codes
// Instead of:
cy.wait('@request').its('response.statusCode').should('eq', 200)

// Use:
cy.wait('@request').its('response.statusCode').should('be.oneOf', [200, 304])

This approach accommodates legitimate response variations and different deployment environments, resulting in more reliable and maintainable network code.
