Test Agents Reliably With Memory Snapshots You Can Pin and Replay

Reliable agent testing requires controllable memory state. Without snapshots, every test run sees different memory and results aren't comparable. MemoryLake provides memory snapshotting — pin memory at known states, test against them, compare outputs.

The problem: agent tests aren't reproducible without memory snapshots

Test A passes. Test B fails. Was it the agent code or memory drift? Without pinned memory, every test runs against a different context. Regression testing becomes unreliable. CI for agent quality is impossible.

How it works for memory snapshot testing

  1. Connect — Create snapshots at known good memory states.
  2. Structure — Tests pin memory to specific snapshots at run time.
  3. Reuse — CI runs against consistent memory; results compare cleanly.
