Give QA engineers instant corrupted fixtures
Ship stronger releases by rehearsing the failure paths customers hit most - without custom scripts or waiting on security teams.
Pain points we hear
Edge cases arrive late
Manual reproduction is slow
Evidence is inconsistent
Outcomes after adoption
Reproduce defects on demand
Automate negative testing
Deliver audit-ready evidence
Reusable playbooks
Daily smoke
Corrupt critical file types before regression sign-off.
- 1.Select top 5 file types used by customers (e.g., PDF, CSV, XLSX).
- 2.Run Byte Flip at 40% intensity to mimic light corruption.
- 3.Capture screenshots and log output for quick triage.
Release hardening
Before every major release, run catastrophic scenarios.
- 1.Corrupt ZIP and MP4 samples using Header Tamper and Entropy Surge.
- 2.Validate expected error messaging across UI, API, and logging layers.
- 3.Attach corruption reports to release notes as evidence.
Regression suite integration
Convert successful corruption runs into automated fixtures.
- 1.Export seeds and modes from the report.
- 2.Drop them into the Hexwilt CLI within your CI pipeline.
- 3.Fail the build if downstream validation deviates from expected outputs.
