Test your tests, not your patience
Mutation testing is brutally honest: it changes your code and asks your tests, “would you notice?”
The problem is that traditional mutation testing is often too expensive:
- Too many mutants
- Too much runtime
- Too much noise (equivalent or low-signal mutations)
MutantZero exists to make mutation testing feel like a high-signal loop: run → review survivors → upgrade tests → repeat.
AI aim-assist (two layers)
MutantZero uses two complementary ideas:
- Archetypes: classify function intent (algorithm, transformer, guard, etc.) so we can generate mutations that match purpose.
- PMT (Predictive Mutation Testing): predict likely-survivors and skip them to save time.
Quick start
npm install -g mutantzero
mutantzero
What’s next
- Solidify the core lanes (AI Intelligence, Performance, Operators, Languages, Reporting, Desktop App)
- Launch MutantZero Cloud: credits-based infrastructure runs for the big suites
