# Testando a Base de Dados { #testing-a-database }

Você pode estudar sobre bases de dados, SQL e SQLModel na [documentação de SQLModel](https://sqlmodel.tiangolo.com/). 🤓

Aqui tem um mini [tutorial de como usar SQLModel com FastAPI](https://sqlmodel.tiangolo.com/tutorial/fastapi/). ✨

- **Rule**: Pattern-based response routing (`RegexRule`, `SitemapsRule`)
- **ResponseProcessor**: `DefaultResponseProcessor`, `SitemapsResponseProcessor`, `NullResponseProcessor`
- **Transformer**: `HtmlTransformer`, `XmlTransformer`, `FileTransformer`, etc.
- **Extractor**: Weight-based selection (tries in descending weight order)
