What Is Software Testing — In One Job's Worth Of Words
2026-05-12 4 min read
Software testing is the discipline of deliberately trying to break a product before customers do, then writing down exactly what broke, how to reproduce it, and why it matters.
On the job that looks like:
- Reading a user story and asking "what could go wrong?"
- Running through the happy path, then the angry path, then the lazy path
- Filing a bug with steps, expected vs actual, severity and priority
- Re-testing after the developer claims a fix
- Doing it again next sprint, faster
The rest — frameworks, automation, certifications — is scaffolding around that core loop.
