How It Works

Testing architecture for the AI era that perfectly replicates production, guarantees full test coverage, manages dependencies, and diagnoses flaky test results.

We Learn From Real Traffic

Manually written tests can't cover all features. Synthetic test data can't cover all scenarios. Softprobe passively observes live production requests.

  • API inputs and Auth context
  • Downstream calls and DB queries
  • External API responses

Ensure 100% coverage of real user behavior.

We Capture the Full Execution State

Flaky tests aren’t flaky. They’re missing context.

We snapshot the entire runtime environment so every test case becomes deterministic and reproducible.

  • Dependency responses and database result sets
  • Feature flags and environment configuration
  • Time-based inputs
  • External API interactions

All failures are reproducible.

4 "context": { "seed": "0x8fa2", "ver": "v1.4.2" }

We Generate Millions of Tests Automatically

We don't generate test code. We generate executable replays from real traffic. No writing tests. No maintaining mocks. No brittle fixtures.

  • Parameterized regression cases
  • Injected dependencies
  • Mirrored environment

Every request becomes a permanent test. Instantly.

We Replay Against Your New Version

When you ship new code, we compare the output of the Old version vs. the New version. If behavior changes unexpectedly, we catch it before users see it.

  • JSON Responses and Structure
  • Side effects (DB writes, events)
  • Schema changes

Zero production risk. Faster releases.

See the Exact Cause of Test Failures

Our session graph architecture retraces errors & behavior changes to the exact point of failure.

  • Visualize preserved states and execution paths
  • Replay full API requests and response bodies
  • Trace the regression to the exact breaking change

Every failure is traceable to its exact cause.
