Y estos modelos están compartiendo muchos de los datos y duplicando nombres y tipos de atributos.

Podríamos hacerlo mejor.

Podemos declarar un modelo `UserBase` que sirva como base para nuestros otros modelos. Y luego podemos hacer subclases de ese modelo que heredan sus atributos (anotaciones de tipos, validación, etc).

        assertThat(i.next().getKey(), is(nullValue()));
        assertThat(i.next().getKey(), is("1"));
        assertThat(i.next().getKey(), is("2"));
    }

    /**
     * Test method for {@link org.seasar.util.collection.ArrayIterator#remove()}
     * .
     */
    @Test
    public void testArrayIteratorRemoveException() {
        exception.expect(ClIllegalStateException.class);

    //                                                                        main
    //                                                                        ============

    /**
     * Main method to start the Fess application.
     * Sets up system properties, configures Tomcat, and starts the server.

#### Blocking APIs

Blocking APIs are convenient because you get top-to-bottom procedural code without indirection. Network calls work like regular method calls: ask for data and it is returned. If the request fails, you get a stacktrace right where the call was made.

                Config.store(log, "JCIFS PROPERTIES");
            } catch (final IOException ioe) {}
        }
    }

    @Override
    public void destroy() {
    }

    /**
     * This method simply calls {@code negotiate( req, resp, false )}
     * and then {@code chain.doFilter}. You can override and call
     * negotiate manually to achive a variety of different behavior.
     */
    @Override

        // Arrange: first ensureTreeConnected comes from pipe
        when(pipe.ensureTreeConnected()).thenReturn(tree);
        when(tree.acquire()).thenReturn(tree); // method returns itself per implementation

        // Act: call twice
        try (SmbTreeHandleImpl t1 = target.ensureTreeConnected(); SmbTreeHandleImpl t2 = target.ensureTreeConnected()) {
            assertSame(tree, t1);

              getLowerEndpoint(),
              getLowerBoundType());
      result.reverse = this;
      return this.reverse = result;
    }
    return result;
  }

  // This method helps J2KT's type inference.
  private static <T extends @Nullable Object> Comparator<T> reverseComparator(
      Comparator<T> comparator) {
    return Ordering.from(comparator).reverse();
  }

Following is an example lambda handler.
```py
from flask import Flask, request, abort, make_response
import requests

app = Flask(__name__)
@app.route('/', methods=['POST'])
def get_webhook():
	if request.method == 'POST':
		# obtain the request event from the 'POST' call
		event = request.json

		object_context = event["getObjectContext"]

		# Get the presigned URL to fetch the requested
		# original object from MinIO

        // Act
        int bytesRead = trans.readDataWireFormat(buffer, 0, 10);

        // Assert
        assertEquals(0, bytesRead);
    }

    @Test
    @DisplayName("Test toString method")
    void testToString() {
        // Arrange
        TransTransactNamedPipe trans = new TransTransactNamedPipe(mockConfig, TEST_FID, TEST_DATA, TEST_OFFSET, TEST_LENGTH);

        // Act

                        IllegalArgumentException.class),

                // Name length larger than remaining bytes - use method reference
                Arguments.of("name length exceeds remaining", (java.util.function.Supplier<byte[]>) () -> {
                    byte[] buf = buildBuffer(der, nameBytes);
