v2.0.0

2026-04-16auto-detect

send() and readRecords() now auto-detect the format. Simpler API, fewer overloads.

Highlights

01
Format auto-detection on publish
KafkaTestPublisher.send(topic, key, value) detects String / Avro GenericRecord / SpecificRecord / JSON DTO from the value type — no more sendJson / sendAvro variants.

02
Format auto-detection on read
KafkaTopicReader.readRecords(topic, Class, count) and readSingleRecord(topic, Class) detect deserialisation format from the target class.

03
Object batch publishing
sendBatch(topic, List<?>) and sendBatch(topic, Map<String, ?>) accept DTOs, Avro records, and strings.

Removed sendJson(), sendAvro(), sendJsonBatch() from KafkaTestPublisher. Use send(topic, key, (Object) value) — format is auto-detected from the value type.
Removed readJsonRecords(), readSingleJsonRecord(), readAvroRecords(), readSingleAvroRecord() from KafkaTopicReader. Use readRecords(topic, Class, count) and readSingleRecord(topic, Class).
Batch methods now accept Map<String, ?> and List<?> instead of Map<String, String> and List<String>, with auto-detection per element.
Explicit schemaRegistryUrl parameters have been removed from the public API; the mock schema registry URL is used internally.
Removed SharedKafkaProperties from public documentation (internal class).
Removed the configuration-constants docs page and api-reference top-level page (consolidated into the api/ section).

Auto-detection of serialisation format in KafkaTestPublisher.send() based on value type.
Auto-detection of deserialisation format in KafkaTopicReader.readRecords() and readSingleRecord().
Object batch publishing: sendBatch(topic, List<?>) and sendBatch(topic, Map<String, ?>).
Comprehensive error handling tests and shared-broker convenience overload tests.
