BitDive

Bitdive provides Regression Safety for Java applications without the hassle of writing mock scripts. Instead of coding tests manually, you simply select real request flows to build versionable Replay Plans. Capture once, then reuse scenarios to build unit replays, integration suites, and contract checks from the same high-fidelity data.

What you get
-Deterministic verification from real behavior. Tests are based on observed executions, not invented data or probabilistic code generation.
-No mock scripts to maintain. Downstream dependencies are isolated using recorded interactions at client and driver boundaries.
-Faster debugging when something breaks. When a replay fails, BitDive provides white box visibility, including cross service call chains, method parameters and results, exceptions, and SQL queries. Root cause is clear without log archaeology.
