Build a CDR Australia data holder mock server for integration testing using the Consumer Data Standards reference implementation

Steps

1. Clone the Consumer Data Standards Australia reference implementation from github.com/ConsumerDataStandardsAustralia/mock-data-holder; this provides a CDR-conformant sandbox with configurable test accounts and transactions
2. Run the mock server locally using Docker Compose; the stack includes an authorization server, resource server, and CDR Register mock — configure ports, test client credentials, and JWKS endpoints in docker-compose.yml
3. Register a test ADR client in the mock CDR Register by POST to the mock register's /cdr-register/v1/banking/data-recipients endpoint with your test JWKS URI and redirect URIs
4. Execute the full CDR authorization code flow against the mock: construct a PAR request with PKCE, receive a request_uri, redirect for consent, and exchange the code for tokens using private_key_jwt
5. Call the mock banking endpoints: GET /cds-au/v1/banking/accounts and GET /cds-au/v1/banking/accounts/{accountId}/transactions; validate that response schemas match the CDR Banking API specification published at consumerdatastandardsaustralia.github.io/standards
6. Run the CDR Conformance Test Suite against your mock integration to identify schema mismatches, missing required fields, or incorrect security configurations before connecting to a real Data Holder
