• Data Volume Testing: Testing the system with a large volume of data to see if it can handle the storage, processing, and retrieval of financial information efficiently.
• Resource Exhaustion Testing: Testing the system by exhausting resources like memory, CPU, and disk space to see how it recovers or fails.
• Error Handling Testing: Testing the system's ability to handle errors and exceptions gracefully. This includes ensuring that the system can recover from failures and that error messages are informative.

Compliance Testing

Compliance testing ensures that the financial application adheres to all relevant regulations and standards.

• Regulatory Compliance Testing: Verifying that the system complies with financial regulations such as GDPR, KYC (Know Your Customer), and AML (Anti-Money Laundering).
• Data Privacy Testing: Ensuring that the system protects sensitive financial data and complies with privacy regulations.
• Audit Trail Testing: Testing the system's audit trails to ensure that all transactions and system activities are properly recorded and can be used for compliance audits.
• Reporting Testing: Verifying that the system can generate accurate and complete reports required by regulatory bodies.

Example: Python Code Snippet for Load Testing

Let's put some Python code to work to demonstrate a simple load test using the Requests library and pytest:

# test_api_load.py
import pytest
import requests
import time

API_ENDPOINT = "https://api.example.com/transactions"
NUM_USERS = 10
REQUESTS_PER_USER = 5

@pytest.fixture(scope="module")
def setup_environment():
    # Any setup needed before running tests, e.g., create users
    print("Setting up the test environment...")
    yield
    print("Tearing down the test environment...")


@pytest.mark.usefixtures("setup_environment")
def test_api_load():
    start_time = time.time()
    for user in range(NUM_USERS):
        for _ in range(REQUESTS_PER_USER):
            try:
                response = requests.post(API_ENDPOINT, json={"amount": 100, "user_id": user})
                assert response.status_code == 200, f"Request failed with status code: {response.status_code}"
                # Add more assertions based on your API response
            except requests.exceptions.RequestException as e:
                pytest.fail(f"Request failed: {e}")
    end_time = time.time()
    total_time = end_time - start_time
    print(f"Total time for {NUM_USERS * REQUESTS_PER_USER} requests: {total_time:.2f} seconds")
    print(f"Average time per request: {(total_time / (NUM_USERS * REQUESTS_PER_USER)):.4f} seconds")

This simple code simulates multiple users sending requests to an API endpoint. You can expand it to include more sophisticated tests, such as checking response times and validating data integrity. Remember that this is a basic example; you can customize it to fit your needs. You can integrate it with more advanced tools and libraries for more comprehensive testing.
