Validation Suite¶

Comprehensive Testing

JAF includes a comprehensive validation suite that ensures production readiness, security compliance, and functional programming best practices. All tests must pass before production deployment.

Overview¶

The JAF validation suite provides multi-tier testing to validate the complete transformation from prototype to production-ready framework:

** Security Validation**: Verifies elimination of vulnerabilities
** Functional Programming Compliance**: Tests immutability and pure functions
** Infrastructure Validation**: Confirms production components work correctly
** Integration Testing**: End-to-end workflow validation

Quick Start¶

Run Master Validation¶

# From project root (recommended)
python3 validation/tests/validate_production_improvements.py

# Expected output:
#  ALL TESTS PASSED - JAF ADK IS PRODUCTION READY!
#  RECOMMENDATION: APPROVED for production deployment

Run All Test Suites¶

# Fast test suite for CI/CD
python3 validation/tests/run_all_tests.py --suite fast

# Comprehensive testing for releases
python3 validation/tests/run_all_tests.py --suite comprehensive

Security Validation¶

Test Categories¶

1. Safe Math Evaluator Validation¶

# Tests secure mathematical evaluation
from adk.utils.safe_evaluator import safe_calculate

# Safe expressions should work
result = safe_calculate("2 + 3 * 4")
assert result["status"] == "success"
assert result["result"] == 14

# Dangerous expressions should be blocked
result = safe_calculate("import os")
assert result["status"] == "error"

2. Input Sanitization Testing¶

# Tests multi-level input protection
from adk.security import AdkInputSanitizer, SanitizationLevel

sanitizer = AdkInputSanitizer(SanitizationLevel.STRICT)

# Test SQL injection detection
dangerous_input = '<script>alert("xss")</script> OR 1=1 --'
result = sanitizer.sanitize(dangerous_input)

assert not result.is_safe
assert len(result.detected_issues) > 0
assert "sql_injection" in result.detected_issues or "xss_injection" in result.detected_issues

3. Authentication Framework Testing¶

# Tests authentication and authorization
from adk.security import validate_api_key, AdkSecurityConfig

# Valid key authentication
validation_result = validate_api_key("test-key", "test-key")
assert validation_result.is_valid

# Invalid key rejection
validation_result = validate_api_key("wrong-key", "test-key")
assert not validation_result.is_valid

Security Test Results¶

Test Category	Before	After	Status
Code Injection	Vulnerable	Protected	Fixed
Input Sanitization	Missing	Comprehensive	Implemented
Authentication	Basic	Enterprise	Enhanced
Authorization	None	Role-based	Added

Functional Programming Validation¶

Immutability Tests¶

1. Session Immutability¶

# Tests that sessions are truly immutable
from adk.types import create_immutable_session, create_user_message

# Create original session
session = create_immutable_session("test", "user", "app")
original_message_count = len(session.messages)

# Add message (should create new session)
message = create_user_message("Test message")
new_session = session.with_message(message)

# Original unchanged, new session has message
assert len(session.messages) == original_message_count
assert len(new_session.messages) == original_message_count + 1
assert session != new_session

2. Pure Function Validation¶

# Tests that functions are pure (no side effects)
from adk.types import add_message_to_session

original_session = create_immutable_session("pure-test", "user", "app")
message = create_user_message("Pure function test")

result_session = add_message_to_session(original_session, message)

# Pure function: original unchanged, new result created
assert len(original_session.messages) == 0
assert len(result_session.messages) == 1
assert original_session != result_session

3. Thread Safety Testing¶

# Tests concurrent operations on immutable data
import threading
import time

def concurrent_operation(session_ref, result_list, thread_id):
    """Simulate concurrent operations on session."""
    for i in range(10):
        msg = create_user_message(f"Thread {thread_id} message {i}")
        new_session = session_ref.with_message(msg)
        result_list.append(len(new_session.messages))
        time.sleep(0.001)  # Small delay

session = create_immutable_session("thread-test", "user", "app")
results = []

# Run concurrent threads
threads = []
for i in range(3):
    thread_results = []
    results.append(thread_results)
    thread = threading.Thread(
        target=concurrent_operation, 
        args=(session, thread_results, i)
    )
    threads.append(thread)
    thread.start()

for thread in threads:
    thread.join()

# All threads should produce consistent results
assert all(len(result_list) == 10 for result_list in results)

Functional Programming Results¶

Principle	Before	After	Status
Immutability	Mutable state	Immutable data	Fixed
Pure Functions	Side effects mixed	Pure functions	Separated
Thread Safety	Race conditions	Thread-safe	Ensured

Infrastructure Validation¶

Production Components Testing¶

1. Configuration System¶

# Tests production configuration
from adk.config import create_adk_llm_config, validate_adk_llm_config, AdkProviderType

config = create_adk_llm_config(AdkProviderType.LITELLM)
assert config.provider == AdkProviderType.LITELLM

errors = validate_adk_llm_config(config)
assert len(errors) == 0

2. Error Handling Framework¶

# Tests circuit breakers and error recovery
from adk.errors import create_circuit_breaker, AdkLLMError

circuit_breaker = create_circuit_breaker(
    name="test-breaker",
    failure_threshold=3,
    recovery_timeout=60
)
assert circuit_breaker is not None

# Test error hierarchy
error = AdkLLMError("Test LLM error")
assert isinstance(error, AdkError)

3. Session Providers¶

# Tests database session providers
from adk.sessions import create_in_memory_session_provider, AdkSessionConfig

config = AdkSessionConfig()
provider = create_in_memory_session_provider(config)
assert provider is not None

# Test provider operations
await provider.store_session(session)
retrieved = await provider.get_session(session.session_id)
assert retrieved.session_id == session.session_id

Infrastructure Results¶

Component	Before	After	Status
Session Providers	Mock only	Redis/PostgreSQL	Implemented
LLM Integration	Simulated	Real providers	Connected
Error Handling	Basic	Circuit breakers	Enhanced
Configuration	Hardcoded	Environment-based	Flexible

Integration Testing¶

End-to-End Workflows¶

1. Security Integration¶

# Tests complete security workflow
from adk.security import AdkInputSanitizer, SanitizationLevel
from adk.types import create_immutable_session, create_user_message
from adk.utils import safe_calculate

# Simulate secure user input processing
sanitizer = AdkInputSanitizer(SanitizationLevel.MODERATE)
user_input = "Calculate 15 * 7 for me please"

# Sanitize input
sanitized = sanitizer.sanitize(user_input)
assert sanitized.is_safe

# Create session with sanitized input
session = create_immutable_session("integration-test", "user", "app")
message = create_user_message(sanitized.sanitized_input)
session_with_msg = session.with_message(message)

# Process mathematical calculation safely
calc_result = safe_calculate("15 * 7")
assert calc_result["status"] == "success"
assert len(session_with_msg.messages) == 1

2. Functional Conversation Flow¶

# Tests functional conversation patterns
from adk.types import create_immutable_session, create_user_message, create_assistant_message

# Build conversation functionally
session = create_immutable_session("func-test", "user", "app")
session = session.with_message(create_user_message("Hello"))
session = session.with_message(create_assistant_message("Hi there!"))
session = session.with_message(create_user_message("How are you?"))
session = session.with_message(create_assistant_message("I'm doing well!"))

# Test conversation integrity
assert len(session.messages) == 4
assert session.messages[0].role == "user"
assert session.messages[1].role == "assistant"
assert session.messages[0].content == "Hello"
