TDD — Test-Driven Development for BitcoinAddressFinder

You are working on BitcoinAddressFinder (group net.ladenthin, Java 21, Maven).

Generic Java TDD Guide

Follow all conventions from the generic Java TDD skill (.claude/skills/java-tdd-guide/SKILL.md). That guide covers:

• Red → Green → Refactor workflow
• File headers (Apache 2.0 license)
• Test framework stack (JUnit 4, DataProviderRunner, Hamcrest, Mockito)
• Test naming, AAA structure, editor folds
• Assertions (Hamcrest only), exception testing
• Data providers, named constants, DRY
• Logger injection (constructor over setter)
• Null safety (JSpecify + NullAway)
• Records, immutability, concurrency
• Import style, anti-patterns, completeness checklist

Project-Specific Supplements

For BitcoinAddressFinder-specific conventions, also follow:

• CODE_WRITING_GUIDE.md — BitHelper radix constants, C-prefix configuration POJOs, custom domain exceptions, graceful shutdown (Interruptable), lambda callbacks
• TEST_WRITING_GUIDE.md — Marker annotations (@AwaitTimeTest, @ToStringTest, @OpenCLTest), timing/await tests, static address constants (StaticKey, P2PKH, P2SH, P2WPKH), platform assumptions, LMDB/OpenCL test patterns, producer test helpers, socket test utilities

Package

net.ladenthin.bitcoinaddressfinder

Build & Test

./mvnw compile       # compile (NullAway enforced)
./mvnw test          # run all tests
./mvnw test -Dnet.ladenthin.bitcoinaddressfinder.disableLMDBTest=true  # skip LMDB tests
