Operational Test Matrix
Routing changes are often quick to implement but difficult to release safely without a clear review model. A compact operational test matrix closes that gap.
For each scenario, define input key, expected target environment, allowed paths, and forbidden paths explicitly. This makes routing correctness immediately verifiable.
{
"testMatrix": [
{ "inputKey": "carrier_a", "expectedEnv": "PROD", "allow": ["prodSend"], "deny": ["testSend"] },
{ "inputKey": "carrier_test", "expectedEnv": "TEST", "allow": ["testSend"], "deny": ["prodSend"] },
{ "inputKey": "unknown_key", "expectedEnv": "OFF", "allow": [], "deny": ["testSend", "prodSend"] }
]
}
In parallel, define expected log indicators per scenario: decision values, permitted send actions, and forbidden send actions.
A critical point is separating routing correctness from channel activation state. A disabled outbound channel is not proof of correct mapping, only a separate runtime condition.
When these layers are validated independently, release decisions become reliable: decision is correct, selected path is correct, execution path is correct.
The outcome is a reproducible review process that speeds up approvals and reduces noise from ambiguous logs.
