Key points
- Record the source of truth and direction of every exchange.
- Test changes and recovery, as well as initial creation.
- Approve launch through evidence and explicit treatment of open defects.
Define the exchange contract before testing
Bring together front desk, housekeeping, the IT owner and contacts for both systems. For each field, record its source, destination, trigger, expected mapping and error behaviour. Distinguish reservation status, physical occupancy, cleaning status and technical unavailability. Combining these concepts for convenience can hide a room that is clean but still unavailable.
Add one test-plan entry for each confirmed trigger: a user action, a scheduled request or a transmitted event, according to the mechanism described by the suppliers. Record the expected destination result and the evidence to retain. Confirm read and write permissions separately. Having a connection does not prove that a change made by a room attendant can be written back to the PMS or that every status is supported.
Prepare an identifiable test data set
Create fictional identifiers reserved for testing and a small set of test rooms. Record the initial state in both systems and the interface configuration. Avoid real guest contact details. One owner authorises changes in the selected environment while another checks that they will not affect a live stay or room sales.
Give each case a reference, a precise action and an expected result written before execution. Collect evidence at both source and destination: identifier, value, observed time and user role. Technical logs support the business check, but they do not prove by themselves that front desk can use the information to make the right decision.
Run the acceptance matrix
| Case | Action | Outcome to define and verify |
|---|---|---|
| Creation | Create a test stay. | Only the agreed data appears within the correct scope. |
| Modification | Change the dates. | The new period replaces the old one without duplication. |
| Cancellation | Cancel the stay. | Tasks follow the agreed cancellation rule. |
| Room move | Move the stay. | Old and new locations remain consistent. |
| Departure | Confirm departure. | The intended trigger occurs without premature room release. |
| Cleaning status | Change an authorised status. | The agreed mapping and permitted direction are respected. |
| Unavailability | Block and release through the approved process. | Cleaning does not remove a technical restriction. |
| Repeated event | Replay an event in an authorised test setup. | No unwanted duplicate task is created. |
| Interruption | Simulate a controlled interruption. | The gap is detectable and recovery loses no change. |
Detailed outcomes depend on the interface contract. If a case is outside scope, record the accepted manual process and its owner. Do not classify an unsupported exchange as a passed test simply because no visible error occurred.
Check events that happen close together
In a fictional example, a stay moves from room 214 to room 216 and is then cancelled. Check the final state of both rooms, the tasks still active and the information available to front desk. Independent room-move and cancellation tests can pass while the sequence reveals an inconsistency that matters in daily operation.
Observe the interval between the action and its operational availability. Compare it with the tolerance defined by the hotel and documented with the supplier. This plan proposes no universal response time. If events arrive in a different order, investigate the final outcome with the integration owner rather than attempting improvised changes to live records.
Turn each defect into an explicit decision
The defect register contains the case reference, initial state, observed result, operational impact, owner, required correction and retest evidence. Separate launch blockers from issues with accepted workarounds. A technically corrected defect remains open until the business scenario has been repeated successfully with the relevant users.
Front desk and housekeeping approve their workflows; IT confirms interface monitoring; management makes the launch decision. No overall score should hide a room released incorrectly or critical information that is inaccessible. Accepted exceptions need a named owner and an explicit internal target date, together with the temporary process that keeps the operation workable.
Plan reconciliation after launch
Decide who checks the first live exchanges, how discrepancies are reported and when to use the agreed continuity procedure. Compare a sample of stays and rooms against the reference records, retaining only the information needed to investigate an issue. Prepare any return to the previous process with the suppliers before launch.
Close acceptance testing with the tested version, business approvals under the hotel’s internal process, open exceptions and support contacts. Significant changes to the PMS, connector or status rules may require the affected cases to be rerun. The test record should remain useful during change, rather than becoming a screenshot showing that a connection once worked.

Frequently asked questions
Should every PMS status be tested?
Test statuses within scope and any that can interact with them. Document the expected treatment of excluded values. An unknown status should not silently be interpreted as a room ready for arrival, especially when a technical restriction may still apply.
Is technical testing enough?
No. Exchange logs must be complemented by checks from business user roles. A value can arrive correctly but be displayed poorly, linked to the wrong location or unavailable when a user needs it to decide the next action.
