**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

## An example file structure { #an-example-file-structure }

Let's say you have a file structure like this:

```
.
├── app
│   ├── __init__.py
│   ├── main.py

 */
package jcifs.internal.smb2.ioctl;

import jcifs.Decodable;
import jcifs.internal.SMBProtocolDecodingException;
import jcifs.internal.util.SMBUtil;

/**
 * SMB2 SRV_COPYCHUNK_COPY response data structure. This structure contains the result
 * of a server-side copy operation.
 *
 * @author mbechler

 */
public class SrvCopyChunkCopyResponse implements Decodable {

    /**

        @Test
        @DisplayName("Should decode error response with correct structure size")
        void testReadErrorResponseValid() throws SMBProtocolDecodingException {
            byte[] buffer = new byte[256];
            int bufferIndex = 0;

            // Write error response structure
            SMBUtil.writeInt2(9, buffer, bufferIndex); // structure size
            buffer[bufferIndex + 2] = 2; // error context count

### Project file structure { #project-file-structure }

Let's say your project file structure looks like this:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
```

Now create a directory to store those static files.

Your new file structure could look like this:

```
.
├── app
│   ├── __init__.py
│   ├── main.py

            byte[] buffer = new byte[256];

            // Execute
            int bytesWritten = request.writeBytesWireFormat(buffer, 0);

            // Verify structure
            assertEquals(49, SMBUtil.readInt2(buffer, 0)); // Structure size
            assertEquals(2, buffer[2]); // Padding
            assertEquals(0x01, buffer[3]); // Read flags
            assertEquals(4096, SMBUtil.readInt4(buffer, 4)); // Read length

        assertNotNull(authenticator);

        // The constant should be accessible and properly named
        // We can't easily test the actual configuration without full DI setup,
        // but we verify the class structure is correct
        assertTrue(true);
    }

    @Test
    public void test_securitySettings_allowUnsecureBasic() throws Exception {
        // Verify the ALLOW_UNSEC_BASIC setting is documented with security warnings
