What I Do

Provide guidance for developing and maintaining the crypto-scout-test library, a Java 25 Maven library offering test support utilities.

Core Components

MockData

Typed API for loading bundled JSON fixtures:

java

// Load SPOT 1m klines
var spotKlines = MockData.get(MockData.Source.BYBIT_SPOT, MockData.Type.KLINE_1);
// Load LINEAR tickers
var linearTickers = MockData.get(MockData.Source.BYBIT_LINEAR, MockData.Type.TICKERS);
// Load crypto-scout FGI
var fgi = MockData.get(MockData.Source.CRYPTO_SCOUT, MockData.Type.FGI);

Sources: CRYPTO_SCOUT, BYBIT_SPOT, BYBIT_LINEAR Types: KLINE_1, KLINE_5, KLINE_15, KLINE_60, KLINE_240, KLINE_D, KLINE_W, TICKERS, PUBLIC_TRADE, ORDER_BOOK_1, ORDER_BOOK_50, ORDER_BOOK_200, ORDER_BOOK_1000, FGI, LPL, BTC_PRICE_RISK, BTC_RISK_PRICE, ALL_LIQUIDATION

PodmanCompose

Container lifecycle management:

java

@BeforeAll
static void setUp() {
    PodmanCompose.up();  // Starts TimescaleDB + RabbitMQ, waits for readiness
}

@AfterAll
static void tearDown() {
    PodmanCompose.down();  // Stops containers, removes volumes
}

RabbitMQ Utilities

Streams Protocol (port 5552):

•StreamTestPublisher.create(reactor, executor, environment, stream)
•StreamTestConsumer.create(reactor, executor, environment, stream)

AMQP Protocol (port 5672):

•AmqpTestPublisher.create(reactor, executor, connectionFactory, queue)
•AmqpTestConsumer.create(reactor, executor, connectionFactory, queue)

DBUtils

java

// Check connectivity
DBUtils.canConnect();
// Clean tables for test isolation
DBUtils.deleteFromTables(dataSource, "crypto_scout.bybit_spot_tickers", "crypto_scout.bybit_spot_kline_1m");

Assertions

java

Assertions.assertTableCount("crypto_scout.bybit_spot_tickers", 5);

Configuration

All settings via system properties:

Property	Default	Description
`test.db.jdbc.url`	`jdbc:postgresql://localhost:5432/crypto_scout`	Database URL
`test.db.user`	`crypto_scout_db`	Database user
`test.db.password`	`crypto_scout_db`	Database password
`test.mq.host`	`localhost`	RabbitMQ host
`test.mq.port`	`5552`	RabbitMQ Streams port
`test.mq.user`	`crypto_scout_mq`	RabbitMQ user
`test.mq.password`	`crypto_scout_mq`	RabbitMQ password
`podman.compose.up.timeout.min`	`3`	Container startup timeout
`podman.compose.down.timeout.min`	`1`	Container shutdown timeout

When to Use Me

Use this skill when:

•Implementing new test utilities or mock data fixtures
•Understanding the library's component architecture
•Configuring test environments with Podman containers
•Working with RabbitMQ Streams or AMQP in tests
•Managing database state in integration tests
