## Why Virtual Environments { #why-virtual-environments }

To work with FastAPI you need to install <a href="https://www.python.org/" class="external-link" target="_blank">Python</a>.

After that, you would need to **install** FastAPI and any other **packages** you want to use.

    /**
     * Set to true if you want to output the current thread name. Defaults to true.
     *
     * @since 4.0.0

    @Config(type = "java.lang.Boolean", defaultValue = "true")
    public static final String MAVEN_LOGGER_SHOW_THREAD_NAME = MAVEN_LOGGER_PREFIX + "showThreadName";

    /**
     * Set to true if you want the Logger instance name to be included in output messages. Defaults to true.

		if cr.debug {
			fmt.Printf("want %q, got %q\n", "\r", string(b))
		}
		cr.err = errMalformedEncoding
		return n, cr.err
	}
	b, err = cr.reader.ReadByte()
	if err == io.EOF {
		err = io.ErrUnexpectedEOF
	}
	if err != nil {
		cr.err = err
		return n, cr.err
	}
	if b != '\n' {
		if cr.debug {
			fmt.Printf("want %q, got %q\n", "\r", string(b))
		}

**FastAPI** provides the same `starlette.testclient` as `fastapi.testclient` just as a convenience for you, the developer. But it comes directly from Starlette.

/// tip

Let's look at how we can make that work.

## pytest.mark.anyio { #pytest-mark-anyio }

You can import it directly from `fastapi`:

```python
from fastapi import Request
```

/// tip

When you want to define dependencies that should be compatible with both HTTP and WebSockets, you can define a parameter that takes an `HTTPConnection` instead of a `Request` or a `WebSocket`.
