• Workflow has triggers
• Workflow has jobs
• Jobs have required structure

✅ Job Configuration:

• Python validation job steps
• PySpark validation job steps
• SQL validation job steps
• Python version specified
• Java version specified (PySpark)
• Action versions specified
• Checkout step present

✅ Trigger Configuration:

• Push triggers configured
• Pull request triggers configured

Terraform Tests (12 tests)

✅ File Validation:

• Terraform file exists
• Has resource definitions

✅ Resource Validation:

• S3 buckets defined (all 4 required)
• IAM roles defined
• Glue jobs defined
• Step Functions defined
• EventBridge rules defined
• CloudWatch alarms defined
• Glue Data Catalog defined

✅ Security Validation:

• S3 encryption configured
• S3 versioning enabled
• S3 public access blocked

✅ Syntax Validation:

• Balanced braces
• Resource blocks present

Integration Tests (4 tests)

✅ Consistency:

• Workflow jobs match Terraform infrastructure
• Workflow tests Task 1 code
• Workflow tests Task 3 code
• Environment consistency across jobs

Total: 31 tests

🎯 Unified Testing Convention

All tasks now follow the same structure:

Component	Task 1	Task 3	Task 4
Test directory	tests/	tests/	tests/
Configuration	pytest.ini	pytest.ini	pytest.ini
Fixtures	conftest.py	conftest.py	conftest.py
Makefile	✅	✅	✅
Reports	reports/	reports/	reports/
Test markers	unit, integration	syntax, logic	workflow, terraform

🚀 Usage

Quick Start (Docker - Recommended)

cd tasks/04_devops_cicd

# Run all tests in Docker (no setup required!)
make test

# Run specific categories
make test-workflow
make test-terraform
make test-integration

Benefits of Docker:

• ✅ No dependency installation needed
• ✅ Consistent environment across all machines
• ✅ Isolated from system Python
• ✅ Same as CI/CD environment

Test Output

Tests generate:

• Console output - Immediate feedback
• JSON report - reports/test_report.json (machine-readable)
• HTML report - reports/test_report.html (human-readable)

📊 Comparison with Tasks 1 and 3

Task 1 (ETL)

• Test files: 20+ test files
• Test count: 54+ tests
• Features: Metrics collection, Spark tests, S3 tests
• Command: make test, make test-with-metrics

Task 3 (SQL)

• Test files: 1 test file
• Test count: 4 tests
• Features: DuckDB isolation, SQL validation
• Command: make test, make test-docker

Task 4 (CI/CD)

• Test files: 3 test files
• Test count: 31 tests
• Features: YAML validation, Terraform validation, integration tests
• Command: make test, make test-workflow, make test-terraform

✅ Benefits

1. Consistency - Same structure as Tasks 1 and 3
2. Automation - Automated validation of CI/CD configuration
3. Early Detection - Catch issues before deployment
4. Documentation - Tests serve as documentation
5. Maintainability - Easy to extend and modify
