[royliz3090-jpg]

Summary

Adds comprehensive API test suite for health_check, config_generator, and benchmark modules.

Closes #6

Changes

• Created tests/test_api_suite.py with:
  • TestHealthCheck: Tests for TCP port checks, HTTP service checks, disk usage, memory usage
  • TestConfigGenerator: Tests for config merging, sensitive value masking, environment config generation
  • TestBenchmark: Tests for argument parsing
  • TestIntegration: Integration tests for tool interactions

Test Coverage

Health Check Tests

• test_check_tcp_port_open: Tests TCP port check when port is open
• test_check_tcp_port_closed: Tests TCP port check when port is closed
• test_check_http_service_ok: Tests HTTP service check when service is healthy
• test_check_http_service_error: Tests HTTP service check when service is unhealthy
• test_check_disk_usage_normal: Tests disk usage check when usage is normal
• test_check_disk_usage_high: Tests disk usage check when usage is high
• test_check_memory_usage_normal: Tests memory usage check when usage is normal
• test_check_memory_usage_high: Tests memory usage check when usage is high

Config Generator Tests

• test_merge_config_simple: Tests simple config merging
• test_merge_config_nested: Tests nested config merging
• test_merge_config_no_mutation: Tests that merge_config does not mutate original dicts
• test_mask_sensitive: Tests sensitive value masking
• test_generate_config_development: Tests config generation for development environment
• test_generate_config_production: Tests config generation for production environment
• test_generate_config_with_overrides: Tests config generation with custom overrides

Benchmark Tests

• test_benchmark_latency_parser: Tests latency benchmark argument parsing
• test_benchmark_throughput_parser: Tests throughput benchmark argument parsing

Integration Tests

• test_health_check_json_output: Tests health check with JSON output format
• test_config_roundtrip: Tests config generation and masking roundtrip

Acceptance Criteria

• Feature implemented
• Passes existing tests
• Code follows conventions
• Includes diagnostic artifacts

Diagnostic Artifacts

Build diagnostic artifacts generated via python3 build.py.
