How to test Temenos Infinity

Temenos Infinity testing is the verification of a bank's configured Temenos Infinity digital banking solution, including its customer journeys, business rules, interfaces and operational controls. Testing should cover the bank's implementation and its connected services, since workflows, configuration and dependencies vary between deployments. The aim is to confirm that customers and staff can complete intended tasks accurately, securely and consistently across supported channels.

Establish the scope before testing

Map the user journeys in scope to their requirements, configuration and connected systems. Depending on the implementation, these may include core banking, payment processing, identity and access management, customer relationship management, notification services and other bank platforms. Confirm which system owns each decision and data item, such as the available balance, payment status or customer permissions.

Record the supported channels, user roles, browsers and devices, along with the environments and test data available. Use synthetic or appropriately anonymised data, and agree controls for access, retention and disposal. Avoid test transactions reaching live payment networks or customer accounts. Where an external dependency is unavailable, use a controlled simulator and record which behaviours it does not represent.

Define expected results at each boundary. A transfer test, for example, may require a successful customer confirmation, a submitted payment instruction, the expected core banking posting, an updated balance and a matching transaction history entry. A green confirmation screen alone does not prove that the transaction completed correctly.

Test customer journeys and business rules

Start with functional testing of critical journeys such as sign-in, account viewing, beneficiary management, payments and servicing actions included in the deployment. Cover valid flows, rejected inputs, permission restrictions, timeouts, interrupted sessions and recovery after a failed step. Verify that validation messages explain the problem without exposing sensitive information.

Derive cases from business rules and acceptance criteria. For a transfer, test permitted and exceeded limits, insufficient funds, an invalid beneficiary, a duplicate submission and relevant approval requirements. Check amount precision, currency handling and any configured cut-off or availability rules. Expected outcomes should include both what the user sees and what the connected systems record.

Test user roles separately. Confirm that each role can perform permitted actions and that restricted actions remain unavailable through the interface and relevant service endpoints. Include session expiry and re-authentication where required by the bank's policy.

Verify integrations and cross-channel consistency

Integration testing checks whether Temenos Infinity and its dependencies exchange the right data and handle responses safely. Validate application programming interface (API) requests and responses against agreed contracts, including field values, error codes, timeouts and retries. Check that a timeout does not create duplicate payments when a user retries an action.

For each important workflow, follow the transaction across system boundaries using a correlation identifier or equivalent trace. Reconcile the customer-facing status with downstream records, such as payment state, account entries and audit events. Test delayed, rejected and unavailable dependencies, then verify recovery and any required customer messaging.

Repeat selected journeys across supported channels, such as web and mobile, when both are in scope. Confirm that changes made in one channel appear correctly in another, subject to the system's expected update timing. Differences in display should not conceal conflicting transaction or account data.

Run regression, security and non-functional checks

After configuration changes, interface changes or upgrades, run regression tests against the affected journeys and their dependencies. Prioritise scenarios by customer and operational impact, including payment execution, access control and balance presentation. Keep a small smoke suite for essential environment checks, then run broader regression coverage at planned release points.

Security testing should follow the bank's approved scope and controls. Check authentication, authorisation, sensitive data handling, session behaviour and audit records. Use authorised security testing methods and test accounts; do not probe production systems without explicit approval. Performance and accessibility checks should reflect agreed service expectations, supported devices and applicable requirements for the deployment.

Example: verify a customer transfer

Create a test customer with a funded account and a permitted beneficiary. Submit a transfer within the configured limit, then verify the confirmation and transaction reference. Check the payment service's accepted status, the expected debit and any required ledger entries, and the transaction's appearance in account history. Confirm that a repeated submission with the same request does not create a second debit. Repeat with insufficient funds and an unavailable payment dependency, checking that the request is rejected or safely recoverable and that displayed status matches the recorded outcome.

Keep evidence for each result, including the tested configuration or build, test data identifier, relevant request and response details, and linked downstream records. This makes failures easier to distinguish from environment drift, stale data or a defect in the digital banking workflow.
