/// tip

If you want to call `async` functions in your tests apart from sending requests to your FastAPI application (e.g. asynchronous database functions), have a look at the [Async Tests](../advanced/async-tests.md) in the advanced tutorial.

## Separating tests { #separating-tests }

In a real application, you probably would have your tests in a different file.

### Thread-Local Storage

Use `CrawlingParameterUtil` to set/get `CrawlerContext` and `UrlQueue` in worker threads. Always clear in finally block with `CrawlingParameterUtil.clearAll()`.

### Resource Cleanup Pattern

Always use try-with-resources for `ResponseData` - temp files are auto-deleted on close.
