Also the DMI plug :maxdepth: 1 cps-ncmp-message-status-codes.rst + +Contract Testing (stubs) +======================== + +The CPS team is committed to supporting consumers of our APIs through contract testing. +Obviously we test our own contracts on a continuous basis as part of the build and delivery process. +CPS uses a contract-first approach. That means we write our OpenAPi contracts first and then generate the interface code from that. +This means our interface implementation simply cannot deviate from the OpenApi contracts we deliver. + +Another advantage is that we can also generate 'stubs'. Stubs are a basic implementation of the same interface for testing purposes. +These stubs can be used by clients for unit testing but also for more higher level integration-like testing where the real service is replaced by a stub. +This can be useful for faster feedback loops where deployment of a full stack is difficult and not strictly needed for the purpose of the tests. + +Stubs for contract testing typically always return the same response which is sufficient for the strict definition of a contract test. +However it is often useful to allow more variation in the responses so different clients or the same client can test different scenarios without having to mock the service. +CPS has implemented what we call 'extended stubs' that allow clients to provide alternate responses.implementation + +The available stubs and how to use them are described in :doc:'cps-stubs'. + + + |
