UL Host Test Tool Module — Authorization Simulator by UL TS B.V.
The Authorization Simulator is an add-on for the UL Host Test Tool that emulates authorization endpoints so teams can validate host-side transaction logic without connecting to live networks. It enables developers, QA engineers, acquirers, and processors to model realistic authorization scenarios, inject controlled faults, and verify system behavior in a safe, repeatable environment.
Key capabilities:
- Simulates issuer/authorization responses for a wide range of positive, negative, and edge-case scenarios
- Configurable rules, response profiles, and test data to reproduce complex business flows
- Deterministic responses and tunable conditions such as timeouts, declines, partial approvals, and reversals
- Fault and latency injection to test resilience, retry logic, and exception handling
- Detailed logging, message tracing, and reports to speed troubleshooting and audits
- Interactive and automated execution modes to support regression suites and CI/CD pipelines
- Seamless pairing with UL Host Test Tool for end-to-end host testing workflows
Typical uses:
- Functional, integration, and regression testing of host, switch, and gateway components
- Pre-certification preparation and internal quality checks
- Troubleshooting production issues by reproducing field scenarios in a controlled lab
- Training and sandboxing for new features without risking live environments
Benefits:
- Accelerates releases by removing dependencies on external systems and windows
- Improves quality through comprehensive, repeatable coverage of corner cases
- Reduces risk by validating behavior under adverse and failure conditions
- Enhances observability with clear, actionable diagnostics
