Scale Your Test Coverage, Not Your Codebase
Stop writing test code to test code.
Build a regression shield that runs anywhere. BitDive isolates services virtually, allowing you to verify logic without spinning up complex staging infrastructure.
- Dependency Virtualization: Test services in total isolation. BitDive virtually replaces downstream calls (DBs, Kafka, APIs).
- Infrastructure-Free Execution: Run integration-level scenarios on a laptop or ephemeral CI agent.
- Eliminate Flakiness & Tech Debt: No fragile scripts or manual mocks. Test against captured deterministic behavior.
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 deterministic, auto-mocked JUnit tests.
- 10-20x Faster Creation: Create 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.
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.
Data-Driven Quality
Stop guessing, start verifying with runtime traces
Traditional tests use "invented" data. BitDive provides the reality layer for enterprise Java, ensuring your AI-built 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.
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.
Regression Safety at Millisecond Speed
Providing both humans and agents with the recorded evidence needed to ship complex logic changes with high confidence.
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.
Script-Free JUnits
Turn JSON traces into high-performance JUnit 5 tests. External dependencies (Databases, Kafka, APIs) are automatically stubbed via Mockito while maintaining total isolation.
Semantic Validation
Verify logic changes against real production scenarios. BitDive `TestMode.UNIT` provides millisecond-fast validation via standard Maven/Gradle lifecycle.
