schemathesis 4.18.4

Release 4.18.4

on Python PyPI

🐛 Fixed

• Serialize nested-object query parameters using recursive bracket notation.
• Detect Tomcat strict-decoder rejection when the response carries the default HTML error page.
• Cover both branches of non-body oneOf: [array, string] parameters by forcing non-empty strings.
• Pin Content-Type to the body media type when it is declared as an explicit header parameter.
• Crash in coverage phase on schemas with property names pattern/minLength/maxLength (e.g. Kubernetes CRDs).
• Crash in fuzzing phase on negative mutations of bundled $ref schemas carrying sibling validation keywords.
• Generate a positive coverage case for additionalProperties: {schema} on objects without explicit type: object.
• Emit a populated positive baseline for type: array parameters so item-level keywords reach coverage.
• Drop wildcard */* from Swagger 2.0 consumes so coverage requests carry a concrete Content-Type.
• Treat 409 Conflict as a valid rejection status for negative_data_rejection.
• Retry slow schema endpoints (read timeouts) under --wait-for-schema. #4058
• False positive negative_data_rejection on query-level additionalProperties mutations. #3730
• Resolve bundled $ref in positive_data_acceptance hint to avoid false "additional properties" suggestions.
• Generate positive body cases for schemas combining allOf with readOnly required properties.
• Emit a unique-array case alongside the duplicate for scalar parameters declaring uniqueItems.
