HOW IT WORKS

Full Context, Stubbed Boundaries, Zero Flakiness

BitDive boots the full Spring context and replays all external boundaries from captured traces. Your entire internal chain is tested with real data. No infrastructure required.

01
CAPTURE

Record Real Execution

BitDive captures the full execution trace: HTTP entry point, method calls, SQL queries, API responses, Kafka messages. This becomes the test scenario.

02
REPLAY

Full Chain Replay

The test boots the full Spring context. All external boundaries (DB responses, HTTP calls, Kafka) are replayed from the captured trace. The entire internal chain runs for real.

03
DETERMINISM

Execution Stability

UUIDs, Random numbers, and Clock values (Instant.now) are fixed to match the recording. Your integration tests are fully predictable across every CI run.

IMPLEMENTATION

Zero-Boilerplate Setup

Minimal code, maximum verification surface

Inherit from `ReplayTestBase` and provide a scenario UUID. BitDive handles Spring context boot, boundary interception, and replay of all external dependencies.

  • No @MockBean Lists: All external boundaries are auto-stubbed from the captured trace.
  • Runtime Traces: Test scenarios use actual captured payloads, SQL results, and API responses from verified executions.
  • Strict Verification: Automatically fail tests if unexpected external calls or SQL queries are detected.
INCIDENT RESPONSE

Instant Bug Reproduction

From production failure to green test in minutes

When a scenario fails in production, capture its `scenarioId` and drop it into your integration test. Replay the exact failure path locally with your debugger attached.

  • Exact Reproduction: Stop trying to "recreate" bugs. Replay the actual execution context.
  • Fix Verification: Prove your fix works by replaying the failing scenario against your local code changes.
  • Permanent Regression Check: Every incident becomes a permanent regression test automatically.
WHAT IT CATCHES

Bugs That Unit Tests Miss

The full Spring context reveals what isolated mocks hide

Unit tests mock the very infrastructure where expensive bugs live. Integration tests exercise the real Spring context, catching issues at the seams between components.

  • @Transactional Bypass: Self-invocation within a bean skips the proxy. Integration tests catch it.
  • Serialization Breaks: ObjectMapper, DTO renames, enum format changes. Real HTTP round-trip reveals them.
  • Security & Validation: Missing @Validated, changed filter chains, broken Spring Security rules.
REAL DATABASE TESTING

Need Real Database Verification?

Catch schema drift, constraint violations, and migration issues with a real PostgreSQL, MongoDB, or Redis via Testcontainers. External APIs still replayed from traces.

Frequently Asked Questions

Common questions about the platform.

Spring defines any test that loads an ApplicationContext as an integration test. BitDive boots the full Spring context with real beans, transactions, validation, and security filters. External boundaries are auto-stubbed from captured traces. This is an integration test by Spring's definition. Some teams call it a "component test" because it tests one service as a whole. Both terms describe the same test.
No. In Replay mode, all dependencies including database responses are replayed from captured traces. You run tests with `mvn test` anywhere — no database, no Docker, no infrastructure. If you need real database verification, see our Testcontainers mode.
ObjectMapper misconfiguration (dates, enums), missing @Validated on controller parameters, @Transactional proxy bypass (self-invocation), JPQL failures against real column types, DTO field renames breaking JSON contracts, Spring Security filter changes blocking requests, and aspect side effects swallowing exceptions.
By recording API responses once and replaying them from the captured trace, your tests never hit the real 3rd party API, avoiding rate limits and costs.
Yes. BitDive captures consumed Kafka messages and replays them to your consumer, ensuring your event-driven architecture is tested with real data.
