Implementation Summary: SDK Examples Validation System

Date: 2026-01-15 Status: Complete and Tested Location: /home/fox/git/un-inception/scripts/validate-examples.sh

Overview

The SDK Examples Validation System is the heart of self-validating documentation. It automatically finds, executes, and validates all SDK example files, proving that documentation examples actually work.

What Was Created

1. Core Validation Script

File: scripts/validate-examples.sh (600+ lines)

Features:

• Recursively finds all example files in clients/*/examples/ directories
• Auto-detects programming language from file extension
• Executes examples via unsandbox API with authentication
• Validates outputs and tracks execution times
• Generates comprehensive reports (JSON + HTML)
• Parallel execution for speed (configurable concurrency)
• Timeout protection (30 seconds per example)
• Detailed logging with color-coded output

Core Functions:

detect_language()           # Identify language from file extension
find_examples()            # Recursively find all example files
validate_example()         # Execute and validate a single example
generate_json_report()     # Create machine-readable JSON report
generate_html_report()     # Create visual HTML dashboard
main()                     # Orchestrate entire validation process

2. Test Suite

File: tests/test_validation_script.sh (230+ lines)

Coverage:

• ✓ Script exists and is executable
• ✓ Bash syntax validation
• ✓ Core functions defined
• ✓ Environment variable handling
• ✓ Language detection patterns
• ✓ Report generation
• ✓ Script execution and artifact creation
• ✓ JSON report format validation
• ✓ HTML report format validation
• ✓ Example file discovery
• ✓ Language extension detection

All 11 tests pass successfully

3. Documentation

File: docs/EXAMPLES-VALIDATION.md (400+ lines)

Includes:

• Comprehensive usage guide
• Environment variable reference
• Language support matrix
• Example creation guidelines
• Report format specifications
• Pipeline integration details
• Troubleshooting guide
• Best practices for maintainers
• Future enhancement suggestions

4. CI/CD Integration

Files Modified: .gitlab-ci.yml

Updated Jobs:

• science-validate-examples: Runs core validation script
• validate-examples: Consumes and verifies science job artifacts

Pipeline Stage: Science (pool burning) - runs in parallel with other science jobs

5. Example Files (for demonstration)

Created sample examples showing proper format:

• clients/python/sync/examples/hello_world.py
• clients/python/sync/examples/fibonacci.py
• clients/javascript/sync/examples/hello_world.js
• clients/go/sync/examples/hello_world.go
• clients/ruby/sync/examples/hello_world.rb

Key Capabilities

Language Support

Detects and validates examples in 12+ languages:

• Python, JavaScript, Go, Rust, Java, Ruby, PHP, TypeScript, C++, C, Bash, Perl

Report Generation

JSON Report (examples-validation-results.json)

• Machine-readable statistics
• Timestamp and versioning
• Per-language execution metrics
• Success/failure counts
• Integration-ready format

{
  "report_type": "examples_validation",
  "timestamp": "2026-01-15T20:44:42Z",
  "summary": {
    "total_examples": 5,
    "total_validated": 5,
    "total_failed": 0,
    "success_rate": "100%"
  },
  "language_stats": [...]
}

HTML Report (examples-validation-results.html)

• Professional visual dashboard
• Status badges (passing/failing)
• Statistics grid with color coding
• Language coverage table
• Execution time metrics
• Responsive design (desktop & mobile)
• Last verified timestamp

Parallel Execution

• Default: 4 concurrent examples
• Configurable: PARALLEL_JOBS environment variable
• Efficient resource usage
• Maintains 30-second timeout per execution

How to Use

Local Testing

# Basic usage
bash scripts/validate-examples.sh

# With API key (for actual execution)
export UNSANDBOX_API_KEY="unsb-sk-xxxxx-xxxxx-xxxxx-xxxxx"
bash scripts/validate-examples.sh

# Verbose output for debugging
VERBOSE=1 bash scripts/validate-examples.sh

# Customize parallel jobs
PARALLEL_JOBS=8 bash scripts/validate-examples.sh

Creating Examples

1. Create directory (if needed):

   mkdir -p clients/{language}/{sync,async}/examples
   

2. Add example file:

   # clients/python/sync/examples/my_example.py
   #!/usr/bin/env python3
   """
   Description of what this example demonstrates
   Expected output: result value
   """
   
   print("Hello from unsandbox!")
   

3. Run validation:

   bash scripts/validate-examples.sh
   

4. Check reports:

   • JSON: science-results/examples-validation-results.json
   • HTML: science-results/examples-validation-results.html

CI/CD Integration

The script is automatically called by GitLab CI:

# In .gitlab-ci.yml
science-validate-examples:
  stage: science
  script:
    - apk add --no-cache curl jq bc
    - bash scripts/validate-examples.sh
  artifacts:
    paths:
      - science-results/

Environment Variables

Variable	Description	Default	Required
UNSANDBOX_API_KEY	API authentication token	(none)	Yes*
UNSANDBOX_API_URL	API endpoint	https://api.unsandbox.com	No
PARALLEL_JOBS	Concurrent executions	4	No
TIMEOUT_SECONDS	Timeout per example	30	No
VERBOSE	Debug output (0/1)	0	No

*Required only for actual execution; without it, script finds examples but skips API calls.

Output Structure

science-results/
├── examples-validation-results.json    # Machine-readable report
├── examples-validation-results.html    # Visual dashboard
└── science-results.xml                 # JUnit format for CI

2. Run validation: bash scripts/validate-examples.sh
3. Verify success in reports
4. Commit changes

Monitoring Health
