* Update docs for testing FastAPI. Include using `POST`, sending JSON, testing headers, etc. New documentation: [Testing](https://fastapi.tiangolo.com/tutorial/testing/#testing-extended-example). PR [#271](https://github.com/tiangolo/fastapi/pull/271).

:checkJavaCmd
if not exist "%JAVACMD%" (
  echo The java.exe command does not exist in PATH nor is JAVA_HOME set, so Apache Maven cannot be started. >&2
  goto error
)

    echo Error: Apache Maven 4.x requires Java 17 or newer to run. >&2

Sonra bunu dependency olarak *path operation function*'dan talep edebilir ve ihtiyaç duyduğumuz her yerde kullanabiliriz.

### Ayarlar ve test { #settings-and-testing }

Ardından, `get_settings` için bir dependency override oluşturarak test sırasında farklı bir settings nesnesi sağlamak çok kolay olur:

{* ../../docs_src/settings/app02_an_py310/test_main.py hl[9:10,13,21] *}

                    throw new InvalidUserDataException("$snippet: "
                        + "Snippet missing a language. This is required by "
                        + "Elasticsearch's doc testing infrastructure so we "
                        + "be sure we don't accidentally forget to test a "
                        + "snippet.")
                }
                // Try to detect snippets that contain `curl`

А далі ми можемо вимагати її у *функції операції шляху* як залежність і використовувати будь-де, де це потрібно.

### Налаштування і тестування { #settings-and-testing }

Потім буде дуже просто надати інший об'єкт налаштувань під час тестування, створивши переписування залежності для `get_settings`:
