Testing Instructions

Quiz App Testing

cd quiz-app
npm run lint       # Check for code style issues
npm run build      # Verify build succeeds

Bank API Testing

cd 7-bank-project/api
npm run lint       # Check for code style issues
node server.js     # Verify server starts without errors

General Testing Approach

• This is an educational repository without comprehensive automated tests
• Manual testing focuses on:
  • Code examples run without errors
  • Links in documentation work correctly
  • Project builds complete successfully
  • Examples follow best practices

Pre-submission Checks

• Run npm run lint in directories with package.json
• Verify markdown links are valid
• Test code examples in browser or Node.js
• Check that translations maintain proper structure

Code Style Guidelines

JavaScript

• Use modern ES6+ syntax
• Follow standard ESLint configurations provided in projects
• Use meaningful variable and function names for educational clarity
• Add comments explaining concepts for learners
• Format using Prettier where configured

HTML/CSS

• Semantic HTML5 elements
• Responsive design principles
• Clear class naming conventions
• Comments explaining CSS techniques for learners

Python

• PEP 8 style guidelines
• Clear, educational code examples
• Type hints where helpful for learning

Markdown Documentation

• Clear heading hierarchy
• Code blocks with language specification
• Links to additional resources
• Screenshots and images in images/ directories
• Alt text for images for accessibility

File Organization

• Lessons numbered sequentially (1-getting-started-lessons, 2-js-basics, etc.)
• Each project has solution/ and often start/ or your-work/ directories
• Images stored in lesson-specific images/ folders
• Translations in translations/{language-code}/ structure

Build and Deployment

Quiz App Deployment (Azure Static Web Apps)

The quiz-app is configured for Azure Static Web Apps deployment:

cd quiz-app
npm run build      # Creates dist/ folder
# Deploys via GitHub Actions workflow on push to main

Azure Static Web Apps configuration:

• App location: /quiz-app
• Output location: dist
• Workflow: .github/workflows/azure-static-web-apps-ashy-river-0debb7803.yml

Documentation PDF Generation

npm install                    # Install docsify-to-pdf
npm run convert               # Generate PDF from docs

Docsify Documentation

npm install -g docsify-cli    # Install Docsify globally
docsify serve                 # Serve on localhost:3000

Project-specific Builds

Each project directory may have its own build process:

• Vue projects: npm run build creates production bundles
• Static projects: No build step, serve files directly

Pull Request Guidelines

Title Format

Use clear, descriptive titles indicating the area of change:

• [Quiz-app] Add new quiz for lesson X
• [Lesson-3] Fix typo in terrarium project
• [Translation] Add Spanish translation for lesson 5
• [Docs] Update setup instructions

Required Checks

Before submitting a PR:

1. Code Quality:

   • Run npm run lint in affected project directories
   • Fix all linting errors and warnings

2. Build Verification:

   • Run npm run build if applicable
   • Ensure no build errors

3. Link Validation:

• Follow the Microsoft Open Source Code of Conduct
• See CONTRIBUTING.md for detailed guidelines
• Reference issue numbers in PR description if applicable

Review Process

• PRs reviewed by maintainers and community
• Educational clarity is prioritized
• Code examples should follow current best practices
• Translations reviewed for accuracy and cultural appropriateness

Translation System

Automated Translation

• Uses GitHub Actions with co-op-translator workflow
• Translates to 50+ languages automatically
• Source files in main directories
• Translated files in translations/{language-code}/ directories

Adding Manual Translation Improvements

1. Locate file in translations/{language-code}/
2. Make improvements while preserving structure
3. Ensure code examples remain functional
4. Test any localized quiz content

Translation Metadata

Translated files include metadata header:

<!--
CO_OP_TRANSLATOR_METADATA:
{
  "original_hash": "...",
  "translation_date": "...",
  "source_file": "...",
  "language_code": "..."
}
-->

Debugging and Troubleshooting

Common Issues

Quiz app fails to start:

• Check Node.js version (v14+ recommended)
• Delete node_modules and package-lock.json, run npm install again
• Check for port conflicts (default: Vite uses port 5173)

API server won't start:

• Verify Node.js version meets minimum (node >=10)
• Check if port is already in use
• Ensure all dependencies installed with npm install

Browser extension won't load:

• Verify manifest.json is properly formatted
• Check browser console for errors
• Follow browser-specific extension installation instructions

Python chat project issues:

• Ensure OpenAI package installed: pip install openai
• Verify GITHUB_TOKEN environment variable is set
• Check GitHub Models access permissions

Docsify not serving docs:

• Install docsify-cli globally: npm install -g docsify-cli
• Run from repository root directory
• Check that docs/_sidebar.md exists

Development Environment Tips

• Use VS Code with Live Server extension for HTML projects
• Install ESLint and Prettier extensions for consistent formatting
• Use browser DevTools for debugging JavaScript
• For Vue projects, install Vue DevTools browser extension

Performance Considerations

• Large number of translated files (50+ languages) means full clones are large
• Use shallow clone if only working on content: git clone --depth 1
• Exclude translations from searches when working on English content
• Build processes may be slow on first run (npm install, Vite build)

Security Considerations

Environment Variables

• API keys should never be committed to repository
• Use .env files (already in .gitignore)
• Document required environment variables in project READMEs

Python Projects

• Use virtual environments: python -m venv venv
• Keep dependencies updated
• GitHub tokens should have minimal required permissions

GitHub Models Access

• Personal Access Tokens (PAT) required for GitHub Models
• Tokens should be stored as environment variables
• Never commit tokens or credentials
