Are you testing your software’s failure modes, or only testing the “happy path”?

Read about a moment on our CTRL OS project where we applied processes for developing safety-critical software, discovered a hole in our assumptions and fixed an important issue.

Software Without Evidence Is Just Belief.

The Eclipse Trustable Software Framework (TSF) has been engineered to provide a practical approach to understanding risks in software engineering.

Speed Up Embedded Software Testing with QEMU Facing hardware delays? Testing embedded software doesn’t have to wait—here’s how QEMU bridges the gap.

Software Testing with QEMU.
No hardware? No problem.

QEMU helps embedded software teams:
- Start development earlier
- Run automated CI testing at scale
- Debug faster in a virtual environment
