"We have tripled our tests and are now executing tests in less than 2 hours with 78% Faster Test Execution"
"We figured out a more efficient way to monitor system health and resolve failures earlier in lower environments."
"TestMu AI has significantly boosted our testing speed, is easy to implement, and provides exceptional support."
"With 70% faster test execution, TestMu AI helped us achieve faster time-to-market and enhanced CX."
Test Every Rasa Layer. One Platform.
AI-native agents that chat and call to plan, run, and score your NLU, dialogue policies, and custom actions across 9 quality and 30+ call metrics.
NLU Pipeline Testing
Rasa's NLU pipeline turns each message into intents and entities. TestMu AI probes every intent with real phrasings across chat and voice, and scores recognition across 9 quality metrics.
Intent and Entity Accuracy
Confirm intents match and entities extract correctly across paraphrases, typos, and accents.
Retrain Regression
Re-run the full intent suite after every model retrain to catch accuracy drops before release.
9 Quality Metrics
Score hallucination, bias, completeness, context awareness, and more on every reply.
From First Intent to Production
Every Stage of Your Rasa Assistant, Covered
Simulate live conversations before launch, then batch-analyze real production transcripts and calls with the same metrics.
Total Quality Coverage for Every Turn
Measure what matters on each turn, from intent and entity recognition to speech-to-text accuracy, bias, and hallucination.
UX and Business Ops Metrics
Track the numbers that decide success, from CSAT and sentiment to containment rate and escalation trends.
Confidence on Every Verdict
Each metric carries a High, Medium, or Low confidence level and an evidence excerpt, so you know how far to trust a Rasa result.
Inside Rasa Testing On TestMu AI
NLU and dialogue, voice and CALM flows, load and CI, plus production conversation analysis, all scored on real Rasa interactions.
NLU & DIALOGUE
Verify NLU and Dialogue on Retrain
Retrain a Rasa model or edit a story and behavior can shift. TestMu AI walks every path to confirm recognition and routing still hold.
Try for free- Intent and entity recognition across paraphrases
- Dialogue routing through stories, rules, and TED policy
- Forms and slot filling validated turn by turn
VOICE & CALM
Test Voice Bots and CALM Flows by Phone
Our evaluator calls your Rasa voice bot like a real caller and drives CALM flows, scoring recognition, custom-action fulfillment, and compliance.
Try for free- Custom actions call your APIs and return expected result
- CALM flow behavior checked against the design intent
- Speech-to-text accuracy and voice quality on real calls
LOAD & PERFORMANCE
Scale to Concurrent Conversations and CI
Simulate concurrent Rasa conversations and calls, check chat-voice parity, and wire cron-driven regression suites into CI, all on HyperExecute.
Try for free- Concurrent conversation and call simulation under load
- Cross-channel parity checks between chat and voice
- Scheduled, cron-driven regression runs in CI/CD
PRODUCTION ANALYSIS
Catch Regressions Before Customers Do
Batch-analyze production Rasa transcripts and call recordings so a drop in containment, CSAT, or intent accuracy never slips past a release.

- Track quality trends across releases over time
- Flag drops in containment, CSAT, or intent accuracy
Built for Every Layer of Rasa Testing
Project & Environment Management
Create testing agents for each Rasa assistant, manage environments, and scope variables with bulk creation support.
Test Profiles & Personas
Drive conversations with reusable test data and 10 pre-built personas plus custom ones, so you simulate real users, accents, and edge cases.
Validation Criteria
Define custom, evidence-based pass/fail rules per scenario, each with High, Medium, or Low confidence tracking.
Security & Infrastructure
Run on HyperExecute with an optional secure tunnel to reach Rasa assistants behind a private network.
Scheduling Engine
Automate runs with preset frequencies or full cron expressions with IANA timezone support, triggered on agent update, manually, or from CI.
Observability & Reporting
