Subunit 5.6: Testing and Validation

Objective: Comprehensive testing of the real Strands integration to ensure production readiness and validate end-to-end pipeline functionality.

Testing Strategy

Phase 1: Unit Testing

Duration: 1-2 hours Goal: Test individual components of Strands integration

1.1 Magic Mirror Integration Tests

  • Test Magic Mirror initialization in Lambda environment
  • Validate repository path handling and extraction
  • Test analysis execution with time constraints
  • Verify output format and content structure

1.2 S3 Integration Tests

  • Test workingcopy download and extraction
  • Validate analysis result upload to correct S3 paths
  • Test file naming and content type handling
  • Verify S3 permissions and access patterns

1.3 EventBridge Integration Tests

  • Test repo_ready event processing
  • Validate analysis_ready event publishing
  • Test error event publishing for failures
  • Verify Component Task Logging Standard compliance

Phase 2: Integration Testing

Duration: 2-3 hours Goal: Test complete pipeline with real repositories

2.1 End-to-End Pipeline Tests

  • Test complete flow: Webhook → Analysis → Delivery
  • Validate with different repository types and sizes
  • Test with CodeRipple repository itself
  • Verify Deliverer can process Strands output correctly

2.2 Repository Variety Tests

  • Small Repository (< 1MB): Simple Python/JavaScript project
  • Medium Repository (1-10MB): Framework-based application
  • Large Repository (10-50MB): Complex multi-language project
  • CodeRipple Repository: Self-analysis validation

2.3 Error Scenario Tests

  • Repository extraction failures
  • Strands analysis timeouts
  • AWS Bedrock service errors
  • S3 upload failures
  • EventBridge publishing errors

Phase 3: Performance Testing

Duration: 1-2 hours Goal: Validate performance within Lambda constraints

3.1 Time Constraint Validation

  • Test analysis completion within 15-minute Lambda limit
  • Measure analysis duration for different repository sizes
  • Validate progressive analysis phases work correctly
  • Test time-aware execution and early termination

3.2 Memory Usage Testing

  • Monitor Lambda memory consumption during analysis
  • Test with repositories of varying complexity
  • Validate temporary file cleanup
  • Ensure no memory leaks or excessive usage

3.3 Cost Analysis

  • Monitor AWS Bedrock API usage and costs
  • Track Lambda execution costs
  • Analyze cost per analysis for different repository types
  • Validate cost efficiency compared to expected usage

Phase 4: Quality Validation

Duration: 1-2 hours Goal: Ensure analysis output quality and consistency

4.1 Output Quality Assessment

  • Validate generated documentation is comprehensive
  • Test analysis adapts to different programming languages
  • Verify repository-specific insights are accurate
  • Ensure professional formatting and structure

4.2 Consistency Testing

  • Run same repository analysis multiple times
  • Verify consistent output quality and structure
  • Test analysis reproducibility
  • Validate no random variations in core content

4.3 Deliverer Compatibility

  • Verify Deliverer can process Strands output
  • Test Showroom website updates work correctly
  • Validate download packages are properly formatted
  • Ensure analysis URLs and links function properly

Test Repositories

Primary Test Cases

  1. CodeRipple (Self-analysis): /Users/robertoallende/code/coderipple
  2. Simple Python Project: Create minimal test repository
  3. JavaScript/Node.js Project: Create typical web application
  4. Multi-language Project: Repository with multiple programming languages

Test Repository Creation

# Create test repositories for validation
mkdir -p /tmp/coderipple-test-repos

# Simple Python project
mkdir -p /tmp/coderipple-test-repos/simple-python
cd /tmp/coderipple-test-repos/simple-python
git init
echo "# Simple Python Project" > README.md
echo "print('Hello, CodeRipple!')" > main.py
echo "requests==2.28.0" > requirements.txt
git add . && git commit -m "Initial commit"

# JavaScript project
mkdir -p /tmp/coderipple-test-repos/simple-js
cd /tmp/coderipple-test-repos/simple-js
git init
echo "# Simple JavaScript Project" > README.md
echo "console.log('Hello, CodeRipple!');" > index.js
echo '{"name": "test-project", "version": "1.0.0"}' > package.json
git add . && git commit -m "Initial commit"
