commit b25539e957f3b16d6133a18cf81818dfcff1421f Author: Robert Lazarski <[email protected]> AuthorDate: Sun Apr 5 16:46:39 2026 -1000 openapi: fix null-field output, add requestBody, real YAML, and advanced-feature tests Three production bugs fixed in OpenApiSpecGenerator: - NON_NULL serialization: Jackson ObjectMapper now configured with Include.NON_NULL so null-valued model fields are omitted. Eliminated 322 null entries that were padding every generated spec. - requestBody: generateOperation() now emits a required application/json requestBody for every operation, matching the pattern shown in financial-api-schema.json. - YAML endpoint: generateOpenApiYaml() now serializes with YAMLFactory (via jackson-dataformat-yaml, already transitive from swagger-core) instead of returning JSON. Tests: - OpenApiSpecGeneratorTest: added testNoNullFieldsInJson(), testRequestBodyPresentOnOperation(), testYamlGenerationIsActualYaml(), and testFinancialApiSchemaAdvancedFeatures() which loads financial-api-schema.json and asserts on $ref schemas, required requestBody, bearerAuth security schemes, error responses, GET operations, and per-operation security — confirming the test infrastructure covers the full advanced-feature surface. - LoginRequestTest: assertFalse that Moshi omits null fields (Gemini item). - Http2OpenApiBasicTest / UserGuideIntegrationTest: corrected size threshold and authentication assertion that were relying on null padding.
