Selective Testing
As a probability problem.
In complex systems, “run everything” is not rigor. It is a habit.
Selective Testing treats validation as an adaptive decision. The goal is information gain.
The shift from execution to selection
Traditional QA optimizes for coverage. Selective Testing optimizes for what remains unknown.
The question changes. Not “How much did we run?”. But “What is most likely to surprise us?”.
Change events
Structural diffs reshape impact. Risk is never static after a commit.
Historical outcomes
Versioned results refine priors. Memory becomes calibration.
Runtime signals
Telemetry shifts uncertainty. Observation changes what matters.
The loop
Change, history, and signals feed a single operation: probability distribution recalibration.
Selection is the output. Learning is the consequence.
- 1InputsChange events, historical outcomes, runtime signals.
- 2RecalibrationUpdate regression probabilities across interdependent components.
- 3SelectionChoose validations by expected information gain.
- 4Execution + LearningResults update the model. The system evolves per run.
How it worksThe Quantik Mind flow
Quantum-inspired selection that learns from history, listens to your systems, and runs only what matters.
- Train risk priors from historical runs (Functional runs & results)
- Learn failure correlations across services (entangled_with graph)
- Calibrate dynamic thresholds using percentiles and z-scores
- Cold-start safe: fallback priors only when no real history exists
- Parse commit metadata and impacted services
- Pull live observability signals (Monitoring metrics, traces, logs, anomalies)
- Load customer test library via API (no hardcoded tests)
- Compute service change magnitude and volatility score
- Superposition: risk-based probabilistic scoring per service
- Entanglement: expand selection using historical + runtime correlations
- Uncertainty: boost under-tested or low-confidence areas
- Output prioritized, minimal set of high-information tests
- Return selected tests via API before pipeline execution
- Customer tools run them (Selenium, Playwrit, Cypress, TestComplete, etc.)
- No framework changes required
- Works in shadow mode or enforced mode
- Persist run results per project (multi-tenant aware)
- Update risk priors and entanglement graph
- Track real KPIs: risk coverage, avoided redundancy, execution delta, etc.
- Structured logs for future ML retraining
1. Risk model initialization
2. Context ingestion
3. Quantum selection engine
4. Execution through existing tooling
5. Learning loop & signal amplification
Selective Testing, operationalized.
Quantik Mind implements this paradigm as a lightweight CI/CD layer. No test rewriting. No framework replacement.
