Testing & Validation

Integration Testing

Webhook Endpoint Testing

• Test all endpoints with various scenarios (happy path and error cases)
• Verify response format compliance
• Test with invalid/malformed requests
• Validate signature verification with various cases

Concurrent Request Testing

• Simulate multiple transactions for same player
• Test database locking mechanisms
• Verify balance consistency under load
• Check for race conditions

Load Testing

Peak Load Simulation

• Test with 2-3x expected peak traffic
• Monitor response times under stress (must stay under 500ms)
• Identify bottlenecks and resource limits

Failover Scenarios

Test these failure cases:

• Database primary failure
• Network partition
• Service dependency outage
• Memory/CPU/disk exhaustion

Test Data Management

Test Player Accounts

• Create dedicated test players with various balance states
• Test edge cases (zero balance, max balance)
• Include multi-currency scenarios if applicable

Essential Test Cases

1. Simple withdraw and deposit operations
2. Rapid consecutive transactions
3. Large amount transactions
4. Minimum/maximum bet scenarios
5. Rollback after withdraw
6. Duplicate tx_id handling

Security Testing

Penetration Testing

• Test authentication bypasses
• Attempt replay attacks
• Verify signature validation robustness
• Check for injection vulnerabilities

Compliance Validation

• Ensure audit logging meets requirements
• Verify data retention policies
• Test transaction history accuracy
