## Testing Your Assistant

### [End-to-End Testing](https://legacy-docs-v1.rasa.com/1.10.21/user-guide/testing-your-assistant/#end-to-end-testing)
Rasa Open Source lets you test dialogues end-to-end by running through test conversations and making sure that both NLU and Core make correct predictions.

### [Evaluating an NLU Model](https://legacy-docs-v1.rasa.com/1.10.21/user-guide/testing-your-assistant/#evaluating-an-nlu-model)
A standard technique in machine learning is to keep some data separate as a test set.

### [Comparing NLU Pipelines](https://legacy-docs-v1.rasa.com/1.10.21/user-guide/testing-your-assistant/#comparing-nlu-pipelines)
By passing multiple pipeline configurations to the CLI, Rasa will run a comparative examination between the pipelines.

### [Intent Classification](https://legacy-docs-v1.rasa.com/1.10.21/user-guide/testing-your-assistant/#intent-classification)
The evaluation script will produce a report, confusion matrix, and confidence histogram for your model.

### [Response Selection](https://legacy-docs-v1.rasa.com/1.10.21/user-guide/testing-your-assistant/#response-selection)
The evaluation script will produce a combined report for all response selector models in your pipeline.

### [Entity Extraction](https://legacy-docs-v1.rasa.com/1.10.21/user-guide/testing-your-assistant/#entity-extraction)
The `CRFEntityExtractor` is the only entity extractor which you train using your own data.

### [Entity Scoring](https://legacy-docs-v1.rasa.com/1.10.21/user-guide/testing-your-assistant/#entity-scoring)
To evaluate entity extraction we apply a simple tag-based approach.

### [Evaluating a Core Model](https://legacy-docs-v1.rasa.com/1.10.21/user-guide/testing-your-assistant/#evaluating-a-core-model)
You can evaluate your trained model on a set of test stories by using the evaluate script.

### [Comparing Core Configurations](https://legacy-docs-v1.rasa.com/1.10.21/user-guide/testing-your-assistant/#comparing-core-configurations)
To choose a configuration for your core model, you want to measure how well Rasa Core will generalise to conversations which it hasn’t seen before.
