   - Using comparative operators with string values will lead to an error at runtime. This error can't be validated earlier as the datatype is unknown until the execution phase.

     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'.
