## Testing Tools

| Tool                      | Purpose                                                                                                               |
| ------------------------- | --------------------------------------------------------------------------------------------------------------------- |
| **Test (Talk to Bot)**    | Chat interface to test conversations in real time. Validates dialog flow, NLP, and task execution.                    |
| **Utterance Testing**     | Enter utterances and see which engine matches them and which intent wins. Identifies ambiguity and incorrect matches. |
| **Health and Monitoring** | Analyzes training data, test coverage, and results. Identifies intent issues and provides training recommendations.   |
| **Batch Testing**         | Runs a set of utterances against the ML model to get statistical accuracy metrics (F1, precision, recall).            |
| **Conversation Testing**  | Simulates end-to-end conversation flows. Create test cases for business scenarios and run them for regression.        |
