### Lanza un `HTTPException` en tu código { #raise-an-httpexception-in-your-code }

`HTTPException` es una excepción de Python normal con datos adicionales relevantes para APIs.

Debido a que es una excepción de Python, no la `return`, sino que la `raise`.

   * @return an unmodifiable list containing the cause chain starting with {@code throwable}
   * @throws IllegalArgumentException if there is a loop in the causal chain
   */
  public static List<Throwable> getCausalChain(Throwable throwable) {
    checkNotNull(throwable);
    List<Throwable> causes = new ArrayList<>(4);
    causes.add(throwable);

    }

    @Test
    void throwsOnUnexpectedStructureSize() throws Exception {
        // structureSize != 49 and != 9 should raise an exception
        byte[] header = buildHeader(NtStatus.NT_STATUS_SUCCESS);
        byte[] buf = new byte[header.length + 10];
        System.arraycopy(header, 0, buf, 0, header.length);

  }

  /** Test that giving a null 'safeChars' string causes a {@link NullPointerException}. */
  @SuppressWarnings("nullness") // test of a bogus call
  public void testBadArguments_null() {
    assertThrows(NullPointerException.class, () -> new PercentEscaper(null, false));
  }

  /**
   * Tests that specifying any alphanumeric characters as 'safe' causes an {@link
   * IllegalArgumentException}.
   */

### In Abhängigkeiten mit `yield` und `except` immer `raise` verwenden { #always-raise-in-dependencies-with-yield-and-except }

Wenn Sie eine Exception in einer Abhängigkeit mit `yield` abfangen, sollten Sie – sofern Sie nicht eine andere `HTTPException` oder Ähnliches auslösen – **die ursprüngliche Exception erneut auslösen**.

Sie können dieselbe Exception mit `raise` erneut auslösen:

// TransitionDate is a embedded type containing time.Time to unmarshal
// Date in Transition
type TransitionDate struct {
	time.Time
}

// UnmarshalXML parses date from Transition and validates date format
func (tDate *TransitionDate) UnmarshalXML(d *xml.Decoder, startElement xml.StartElement) error {
	var dateStr string
	err := d.DecodeElement(&dateStr, &startElement)
	if err != nil {

* TLS Termination Proxy: прокси-сервер TSL-терминации
* utilize (resources): использовать
* сontent: содержимое (or `контент`)
* raise exception: вызвать исключение (also possible to use `сгенерировать исключение` or `выбросить исключение`)
* password flow: password flow (clarify as `аутентификация по паролю` if needed)
* tutorial: руководство (or `учебник`)
