`TestClient`, [HTTPX](https://www.python-httpx.org) tabanlıdır ve neyse ki API'yi test etmek için HTTPX'i doğrudan kullanabiliriz.

## Örnek { #example }

Basit bir örnek için, [Daha Büyük Uygulamalar](../tutorial/bigger-applications.md) ve [Test Etme](../tutorial/testing.md) bölümlerinde anlatılana benzer bir dosya yapısı düşünelim:

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

      throw new SkipThisScenarioException();
    }
  }

  // This exclusion doesn't exclude the TOMBSTONE objects we set. So 'done' NEW futures will look
  // larger than they are.
  @SuppressWarnings("FutureReturnValueIgnored")
  @Footprint(exclude = {Runnable.class, Executor.class, Thread.class, Exception.class})
  public Object measureSize() {
    for (Thread thread : blockedThreads) {

In previous versions, the whole object was logged in audit events. Starting in 1.11, only `status`, `reason`, and `code` are logged. Code that relies on the older version must be updated to avoid errors.

Dieser Anbieter berechnet Ihnen möglicherweise Gebühren pro <abbr title="Request – Anfrage: Daten, die der Client zum Server sendet">Request</abbr>, und der Aufruf könnte etwas länger dauern, als wenn Sie einen vordefinierten <abbr title="Platzhalter, vorgetäuscht, zum Schein">Mock</abbr>-Benutzer für Tests hätten.

    // TODO(kevinb): check more preconditions (as bufferSize >= chunkSize) if this is ever public
    checkArgument(bufferSize % chunkSize == 0);

    // TODO(user): benchmark performance difference with longer buffer
    // always space for a single primitive
    this.buffer = ByteBuffer.allocate(bufferSize + 7).order(ByteOrder.LITTLE_ENDIAN);
    this.bufferSize = bufferSize;
    this.chunkSize = chunkSize;
  }

  public static <K, V> CacheLoader<K, V> asyncReloading(
      CacheLoader<K, V> loader, Executor executor) {
    checkNotNull(loader);
    checkNotNull(executor);
    return new CacheLoader<K, V>() {
      @Override
      public V load(K key) throws Exception {
        return loader.load(key);
      }

      @Override

Der `RequestValidationError` enthält den empfangenen `body` mit den ungültigen Daten.

Sie könnten diesen während der Entwicklung Ihrer Anwendung verwenden, um den Body zu loggen und zu debuggen, ihn an den Benutzer zurückzugeben usw.

`TestClient` 是建立在 [HTTPX](https://www.python-httpx.org) 之上，所幸我們可以直接使用它來測試 API。

## 範例 { #example }

作為簡單範例，讓我們考慮與[更大型的應用](../tutorial/bigger-applications.md)與[測試](../tutorial/testing.md)中描述的類似檔案結構：

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

檔案 `main.py` 會是：

* `minimum_size` - Do not GZip responses that are smaller than this minimum size in bytes. Defaults to `500`.
* `compresslevel` - Used during GZip compression. It is an integer ranging from 1 to 9. Defaults to `9`. Lower value results in faster compression but larger file sizes, while higher value results in slower compression but smaller file sizes.

## Other middlewares { #other-middlewares }

There are many other ASGI middlewares.

For example:

	dynamicTimeoutDecreaseThresholdPct = 0.10 // Lower threshold for failures in order to decrease timeout
	dynamicTimeoutLogSize              = 16
	maxDuration                        = math.MaxInt64
	maxDynamicTimeout                  = 24 * time.Hour // Never set timeout bigger than this.
)

// timeouts that are dynamically adapted based on actual usage results
