### Bug or Regression

- Client-go: resolves an issue with informers falling back to full list requests when timeouts are encountered, rather than re-establishing a watch. ([#89976](https://github.com/kubernetes/kubernetes/pull/89976), [@liggitt](https://github.com/liggitt)) [SIG API Machinery and Testing]

import org.junit.jupiter.api.Test;

class SmbComNtTransactionResponseTest {

    private TestableSmbComNtTransactionResponse response;

    // A concrete implementation of the abstract class for testing purposes.
    private static class TestableSmbComNtTransactionResponse extends SmbComNtTransactionResponse {
        @Override
        int writeSetupWireFormat(byte[] dst, int dstIndex) {
            return 0;
        }

## Пример

В качестве простого примера, давайте рассмотрим файловую структуру, схожую с описанной в [Большие приложения](../tutorial/bigger-applications.md){.internal-link target=_blank} и [Тестирование](../tutorial/testing.md){.internal-link target=_blank}:

6.  For the mainline flavor, we test the libraries using OpenJDK 8, 11, and 17
    on Linux, with some additional testing on newer JDKs and on Windows. Some
    features, especially in `com.google.common.io`, may not work correctly in
    non-Linux environments. For the Android flavor, our unit tests also run on
    API level 23 (Marshmallow).
