Aşağıdaki argümanlar desteklenir:

* `allowed_hosts` - Hostname olarak izin verilmesi gereken domain adlarının listesi. `*.example.com` gibi wildcard domain'ler subdomain eşleştirmesi için desteklenir. Herhangi bir hostname'e izin vermek için `allowed_hosts=["*"]` kullanın veya middleware'i hiç eklemeyin.

`TestClient` побудований на основі [HTTPX](https://www.python-httpx.org), і на щастя, ми можемо використовувати його безпосередньо для тестування API.

Для простого прикладу розгляньмо структуру файлів, подібну до описаної в [Більші застосунки](../tutorial/bigger-applications.md) та [Тестування](../tutorial/testing.md):

Você pode definir esses casos usando uma lista na declaração de tipo.

Você receberá todos os valores do cabeçalho duplicado como uma `list` Python.

Por exemplo, para declarar um cabeçalho de `X-Token` que pode aparecer mais de uma vez, você pode escrever:

 * String type = toolchain.getType(); // Get the type of the toolchain
