Because this endpoint is configured to permit unauthenticated access, the response status code is 200. shouldGetUnauthorizedWhenCreateProductWithoutAuthToken() invokes the secured POST /api/products endpoint without an Authorization header and asserts the response status code is 401 (Unauthorized). shouldCreateProductWithAuthToken() first obtains an access_token using the Client Credentials flow. It then includes the token as a Bearer token in the Authorization header when invoking POST /api/products and asserts the response status code is 201 (Created).\n\nThe getToken() helper method requests an access token from the Keycloak token endpoint using the client ID and client secret that were configured in the exported realm.\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
