     Integer so the cps query will not work if the value is passed as string.

+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'.
