Test Every Bland AI Pathway and Call. One Platform.
Test Your Bland AI Conversational Pathways
Bland agents follow node-based Conversational Pathways. Simulate thousands of callers and score every turn on 9 quality metrics to prove each branch behaves.

9 Quality Metrics
Score bias, hallucination, completeness, context awareness, response quality, conversation flow, user satisfaction, file handling, and file generation accuracy on every turn, so a missing knowledge node never becomes a guessed answer.
Branch and Loop Coverage
Auto-generate scenarios from your PDFs, Confluence, Jira, or GitHub and drive callers down every branch, including reschedules, cancellations, and the edge cases your decision nodes were built to catch.
Go-Live Assessment
Get a Green, Yellow, or Red production-readiness verdict with customizable 0-100% pass/fail thresholds before the pathway goes live on a phone line.
From the First Ring to Full Production
Pre- and Post-Launch, End to End
Rehearse every pathway with simulated callers and live test calls before you flip the inbound number on, then batch-analyze the real recordings with the same metrics, so quality holds from the first pilot call to a full outbound campaign.

Total Quality Coverage for Bland Agents
Score pathway conversations across 9 quality metrics and phone calls across 30+ flow, accuracy, audio, and speech-to-text metrics, from branching logic to how the agent sounds on the line.

Caller Experience and Ops Metrics
Track CSAT and detected sentiment, containment rate, early-termination rate, and how often a call escalates to a live human transfer across every Bland conversation.

Go-Live Assessment by Confidence
Get a Green, Yellow, or Red verdict from four weighted dimensions, with confidence levels scaled to how many calls you tested before launch.

Inside Bland AI Phone Testing on TestMu AI
9 QUALITY METRICS
Score Conversations on 9 Quality Metrics
Your Bland agent is driven down every pathway branch across thousands of caller scenarios and scored on the same nine metrics every turn, with customizable 0-100% pass/fail thresholds.
Try for free- Bias, hallucination, and completeness checks
- Context awareness across pathway branches
- CSAT, file handling, and generation accuracy
PRE & POST EVALUATION
Test Before Launch, Analyze After
Pre-launch rehearses pathways with simulated callers and live test calls; post-launch batch-analyzes the real recordings and transcripts, so quality holds from first pilot to full outbound campaign.
Try for free- Live test calls into your inbound line
- Passive monitoring and outbound number pool
- Batch analysis of production recordings
SCENARIO & VOICE CONFIGURATION
Configure Scenarios and Voices
Shape each test to mirror the real world a caller answers in: generate scenarios from your own knowledge, pick a cloned or library voice, layer background noise, and control call flow down to response timing.
Try for free- Auto-generated scenarios and a persona library
- 15 background-noise presets for resilience
- Masked numbers and call-flow controls
AUDIO, STT & ISSUE DETECTION
Catch Failures Automatically
Beyond pass and fail, the platform surfaces exactly why a call broke, from a hallucinated policy or wrong-branch route to a stalled webhook, patchy audio, or incorrect speech-to-text, with precise mismatch logging.
Start Testing Your Bland AI Agent- Pitch tracker, Voice Quality Index, and SNR
- Speech-to-text accuracy mapping
- Automated issue tags for every failure
Built on Universal Testing Foundations
Project & Environment Management
Create agents, manage test environments, and scope pathway variables with bulk creation support.
Test Profiles & Personas
Inject reusable key-value caller data and use a pre-built or custom persona library for targeted scenarios.
Validation Criteria
Define custom, evidence-based pass/fail rules per pathway scenario with High/Medium/Low confidence tracking.
Security & Infrastructure
Execute via HyperExecute with optional secure tunnels for firewall-restricted voice and webhook endpoints.
Scheduling Engine
Automate call runs using preset frequencies or full custom cron expressions with IANA timezone support.
Go-Live Assessment
Get a Green, Yellow, or Red verdict from four weighted dimensions with AI-powered failure-pattern analysis.
