THE UNIT TESTING PROTOCOL

Regression Safety at Millisecond Speed

Providing both humans and agents with the recorded evidence needed to ship complex logic changes with high confidence.

01
CAPTURE

Record the Reality

BitDive Agent watches your production or staging traffic, capturing exact method arguments, complex object states, and return values. Verify **Complex Business Logic** with zero manual data creation.

02
REPLAY

Script-Free JUnits

Transform JSON traces into high-performance JUnit 5 tests. External dependencies (Databases, Kafka, APIs) are automatically stubbed via Mockito while maintaining total isolation.

03
VERIFY

Semantic Validation

Verify logic changes against real production scenarios. BitDive `TestMode.UNIT` provides millisecond-fast validation via standard Maven/Gradle lifecycle.

PHILOSOPHY

Manual Mocking is Dead

Transform recorded reality into executable logic

Traditional unit testing forced you to maintain thousands of lines of fragile Mockito setup. BitDive turns real traffic into an immutable Ground Truth Protocol.

  • ✓10-20x Faster Creation: Generate complex scenarios in minutes, not hours.
  • ✓Minimal Boilerplate: JSON-driven definitions replace verbose Java mock scripts.
  • ✓Instant Updates: Refresh tests automatically when the underlying logic evolves.
ISOLATION TIER 1

Atomic Method Isolation

Zero-infra, pure logic verification

BitDive runs without the `Spring ApplicationContext`, achieving millisecond execution while maintaining absolute isolation from external environment noise.

  • ✓Mockito Inline Interception: Harness uses `mockito-inline` to intercept `new` calls, static methods, and final classes without manual stubs.
  • ✓Deterministic Replay: Same inputs always result in the same execution path, proven by reality.
  • ✓Standard Maven Execution: Run tests via `mvn test` and Surefire. Fully compatible with Jenkins, GitHub Actions, and GitLab.
ROI & BUSINESS VALUE

Data-Driven Quality

Stop guessing, start verifying with Ground Truth

Traditional tests use "invented" data. BitDive provides the reality layer for enterprise Java, ensuring your AI-generated code survives the real world.

  • ✓80% Time Savings: Move from tedious manual test writing to automated verification auditing.
  • ✓Reliable Regressions: Detect "semantic drift" in complex logic that headers alone can't catch.
  • ✓Fluent Assertions: Use AssertJ or standard JUnit 5 assertions to verify state against recorded reality.
RESILIENCE

Fearless Legacy Refactoring

Your automated regression safety net

Monoliths are "black boxes" where developers fear to tread. BitDive captures "as-is" behavior, creating a baseline that ensures correctness.

  • ✓Zero-Touch Baseline: BitDive `UnitTestRunner` maps out behavior for legacy modules with zero code changes.
  • ✓Detect Side Effects: Catch unintended changes in SQL patterns or internal state instantly.
  • ✓AI-Ready Cleanup: Clean up legacy debt with LLMs, then prove behavioral identity with BitDive.
