Direct Answer (TL;DR)
Brilo AI’s guidance for manual vs AI test cases recommends prioritizing manual test cases for new, high-risk, or compliance-sensitive call flows, and using AI-generated test cases to expand coverage and speed regression testing. Manual test cases are best early in development and for any scenario that requires judgment, privacy review, or complex human escalation paths. AI-generated test cases (synthetic test cases) are useful for broad conversational coverage, load-style variations, and continuous regression suites once core behaviors are validated. Combine both in a repeatable test suite so Brilo AI voice agent changes are validated fast and safely.
How should I rank manual vs AI test cases? — Manual test cases first for high-risk or new flows; AI tests for scale and regression.
Should I trust AI-generated tests for compliance checks? — Use manual tests for compliance and privacy-sensitive checks; use AI tests for supplementary coverage.
When do I switch to mostly AI-driven tests? — After manual validation and guardrail configuration, shift routine regression to AI-generated tests.
Why This Question Comes Up (problem context)
Enterprises ask this because scaling conversational testing across many call flows is expensive and risky. Regulated sectors such as healthcare, banking, and insurance must control for privacy, correctness, and escalation behavior before an automated voice agent handles live calls. Brilo AI buyers need a clear, auditable testing strategy that reduces time-to-production without creating compliance or customer-experience gaps. Teams also want predictable handoff behavior and reproducible test artifacts for audits and change control.
How It Works (High-Level)
Brilo AI separates testing into two complementary streams: manual test cases for exploratory and compliance-sensitive validation, and AI-generated test cases for broad conversational coverage and regression testing. In practice, you hand-author canonical call flows and acceptance criteria in Brilo AI, then seed the system with real call transcripts or canonical prompts so the platform can produce synthetic variations for scale. Use the Brilo AI self-learning voice agents guidance to tune how synthetic conversations mirror real intent and language patterns.
"In Brilo AI, a manual test case is a human-written scenario that asserts expected prompts, responses, and escalation behavior for a specific call flow."
"In Brilo AI, an AI-generated test case is a synthetic conversation produced from seed examples to exercise variants, phrasing, and edge-case prompts at scale."
"In Brilo AI, regression testing is a repeatable test suite that runs after model or script updates to confirm previously validated behaviors remain unchanged."

Guardrails & Boundaries
Treat Brilo AI automated test outputs as supplemental, not a replacement, for human review in sensitive areas. Set these boundaries:
Require manual approval for any call flow that collects or transmits protected data, triggers financial decisions, or affects patient care.
Limit AI-generated test cases from being used as sole evidence for compliance; maintain human-reviewed test artifacts for audits.
Configure intent thresholds and answer-quality filters in Brilo AI so low-confidence responses trigger human handoff instead of automated completion.
"In Brilo AI, an answer-quality guardrail is a configured threshold that forces an escalation or human handoff when model confidence falls below a set level."

Applied Examples
Healthcare example:
Use manual test cases to validate appointment booking flows that require PHI confirmation and consent. After manual approval, add AI-generated test cases to cover phrasing variants and no-answer or silence scenarios. Do not rely on synthetic tests alone for HIPAA-related behavior; retain manual evidence of consent flows.
Banking/Financial services example:
For a debt-collection reminder flow, create manual test cases that verify promise-to-pay capture, dispute routing, and logging. Use AI-generated test cases to validate tone detection, multi-turn payment attempts, and numeric input parsing across accents and phrasing. Maintain a human-reviewed escalation path for any payment or authentication step.
Insurance example:
Manually test eligibility checks, policy changes, and claims triage paths that could have financial impact. Supplement with AI-generated permutations to exercise edge cases and multi-intent calls so Brilo AI voice agent routing and intent recognition remain robust under diverse language.
Human Handoff & Escalation
Brilo AI supports explicit handoff points inside call flows. Configure these patterns:
Escalate on low-confidence responses: set a confidence threshold so the Brilo AI voice agent routes the caller to a human or to a secondary verification workflow when uncertain.
Escalate on policy triggers: tag phrases or intents (for example, “I want to dispute this”) so Brilo AI routes immediately to a specialist queue.
Escalate after N-turns: define turn limits where repeated non-resolution prompts transfer to an agent.
When you design manual test cases, include handoff acceptance criteria (who receives the call, what context is passed, what logging is required). For AI-generated test cases, ensure the synthetic conversations also exercise these escalation triggers.
Setup Requirements
Collect seed transcripts and example calls that represent your canonical call flows and common customer intents.
Define acceptance criteria and success signals for each flow, including confidence thresholds, required data capture, and escalation conditions.
Upload or map historical call examples into Brilo AI so the system can generate synthetic variations.
Configure intent routing and handoff queues inside Brilo AI, including the human queue endpoints and context fields to pass on handoff.
Create a baseline manual test suite for high-risk and compliance flows and store the results for auditability.
Generate AI-driven test cases from seeds and add them to an automated regression pipeline that runs after script or model updates.
Review failed AI-generated tests and convert high-value failures into permanent manual test cases when they indicate business risk.

Business Outcomes
A combined approach reduces time-to-deploy while keeping risk managed. Manual test cases protect compliance and high-impact behaviors; AI-generated test cases reduce manual effort for broad conversational coverage, accelerate regression testing, and surface uncommon phrasing and edge cases. The outcome for Brilo AI customers is fewer production incidents, faster iteration on call flows, and maintainable test artifacts for audits and cross-team collaboration.
FAQs
How many manual test cases should I keep?
Keep manual test cases for all high-risk, compliance-sensitive, and core business flows. Convert recurring AI-generated failures into manual tests; maintain a lean manual suite plus a larger synthetic regression suite.
Can Brilo AI generate test cases directly from call logs?
Yes. Brilo AI can use call transcripts and example interactions to produce synthetic test variations, but you must review and approve generated cases before relying on them for compliance or production validation.
Should I run AI-generated tests in production?
No. Run AI-generated tests in a sandbox or staging environment that mirrors production routing and integrations. Do not use synthetic test traffic in live production channels that could affect customers.
How do I make test results auditable?
Store test inputs, outputs, model versions, configuration snapshots, and human review notes alongside your test artifacts. Retain manual test evidence for regulated workflows.
