Cypress E2E Testing Standards Skill

Overview

This skill provides comprehensive standards for Cypress End-to-End (E2E) testing in CUI projects. It extends base JavaScript testing standards with framework-specific adaptations designed for browser-based test automation scenarios.

What This Skill Provides

Framework Configuration:

• ESLint configuration adapted for Cypress testing contexts
• Complexity thresholds adjusted for E2E test scenarios
• Plugin integration for Cypress-specific rules

Test Organization:

• Directory structure and file naming conventions
• Custom command patterns for reusable test logic
• Constants organization using DSL-style patterns
• Test isolation and session management strategies

Quality Standards:

• Console error monitoring and zero-error policy
• Allowed warnings system for third-party libraries
• Test reliability and stability requirements
• Performance optimization patterns

Best Practices:

• No branching logic in tests (mandatory)
• Explicit assertions over conditional checks
• Session management for test isolation
• Navigation patterns and page type verification
• Modern Cypress patterns (cy.session, custom commands)

Build Integration:

• NPM scripts configuration
• Maven integration patterns
• CI/CD pipeline considerations

When to Activate

Activate this skill when:

• Implementing Cypress E2E tests in CUI projects
• Configuring Cypress testing infrastructure
• Creating custom commands or test utilities
• Reviewing or refactoring existing E2E test suites
• Troubleshooting test reliability issues
• Integrating E2E tests with build systems

Workflow

1. Initial Setup

• Review cypress-configuration.md for ESLint and framework setup
• Apply build-integration.md for Maven and NPM integration
• Implement console-monitoring.md patterns for error tracking

2. Test Development

• Follow test-organization.md for file structure and naming
• Apply testing-patterns.md for custom commands and reusable logic
• Use DSL-style constants for selectors and test data

3. Quality Assurance

• Enforce no-branching-logic rule in all tests
• Implement console error monitoring
• Verify session management and test isolation
• Apply performance optimization patterns

4. Maintenance

• Keep custom commands updated with application changes
• Validate test reliability in CI/CD environment
• Review and update allowed warnings list as needed

Standards Organization

Core Configuration

cypress-configuration.md - ESLint setup, complexity adaptations, global configuration

Test Structure

test-organization.md - Directory layout, file naming, constants organization, custom commands

Testing Patterns

testing-patterns.md - Best practices, session management, navigation patterns, error handling, anti-patterns

Quality Monitoring

console-monitoring.md - Zero-error policy, allowed warnings system, error tracking implementation

Build System

build-integration.md - NPM scripts, Maven integration, CI/CD pipeline setup, dependency management

Tool Access

This skill requires:

• Read access to project files for analysis
• Write access for creating/updating test files and configuration
• Bash access for running Cypress commands and build tools
• Grep/Glob for searching existing test patterns

Integration with Other Skills

This skill builds upon:

• cui-javascript: Base JavaScript standards and modern patterns
• cui-javascript-linting: ESLint configuration foundation
• cui-javascript-unit-testing: Shared testing concepts and patterns
• cui-javascript-project: Project structure and dependency management

Critical Rules

Mandatory:

• No branching logic (if/else, switch, ternary) in tests
• Use navigation helpers instead of direct cy.visit() or cy.url()
• Always verify session context after authentication
• Implement console error monitoring in all test suites

Prohibited:

• cy.wait() with fixed timeouts
• Element existence checks in test logic
• Manual session clearing without helpers
• Direct URL manipulation

Success Criteria

Tests following these standards will:

• Execute reliably in CI/CD environments
• Provide clear failure diagnostics
• Complete within reasonable timeframes
• Maintain clean session isolation
• Detect console errors and warnings
• Use consistent, maintainable patterns
