    system. We've fixed this with a new package (`okhttp3.java.net.cookiejar`) and a new artifact,
    `com.squareup.okhttp3:okhttp-java-net-cookiehandler`. (The original artifact now delegates to
    this new one.)

    ```kotlin
    implementation("com.squareup.okhttp3:okhttp-java-net-cookiehandler:5.0.0-alpha.12")
    ```

Você provavelmente quer testar o provedor externo uma vez, mas não necessariamente chamá-lo em todos os testes que executarem.

Neste caso, você pode sobrepor (*override*) a dependência que chama o provedor, e utilizar uma dependência customizada que retorna um *mock* do usuário, apenas para os seus testes.

### Utilize o atributo `app.dependency_overrides`

		if offset >= int64(len(block)) {
			// Decrement offset.
			offset -= int64(len(block))
			continue
		}

		// Skip until offset.
		block = block[offset:]

		// Reset the offset for next iteration to read everything
		// from subsequent blocks.
		offset = 0

		// We have written all the blocks, write the last remaining block.
		if write < int64(len(block)) {
			n, err := dst.Write(block[:write])

		func(ctx context.Context) (time.Time, error) {
			return time.Now(), slowCaller(ctx)
		},
	)

	ctx, cancel := context.WithCancel(context.Background())
	cancel() // cancel context to test.

	_, err := cache.GetWithCtx(ctx)
	if !errors.Is(err, context.Canceled) {
		t.Fatalf("expected context.Canceled err, got %v", err)
	}

	ctx, cancel = context.WithCancel(context.Background())
	defer cancel()

This would be typical after a user initiates a force refresh by a pull to refresh type action.

```java
    val urlIterator = cache.urls()
    while (urlIterator.hasNext()) {
      if (urlIterator.next().startsWith("https://www.google.com/")) {
        urlIterator.remove()
      }
    }
```

### Troubleshooting

1. Valid cacheable responses are not being cached

  interface Callback {
    fun onEvent(
      id: String?,
      type: String?,
      data: String,
    )

    fun onRetryChange(timeMs: Long)
  }

  /**
   * Process the next event. This will result in a single call to [Callback.onEvent] *unless* the
   * data section was empty. Any number of calls to [Callback.onRetryChange] may occur while
   * processing an event.
