awkward-to-reproduce situations like 500 errors or slow-loading responses.


### Example

Use MockWebServer the same way that you use mocking frameworks like
[Mockito](https://github.com/mockito/mockito):

1. Script the mocks.
2. Run application code.
3. Verify that the expected requests were made.

Here's a complete example:

### Java
```java
public void test() throws Exception {

import java.util.concurrent.ExecutionException;
import java.util.concurrent.Executor;
import java.util.concurrent.TimeUnit;
import java.util.concurrent.TimeoutException;
import java.util.concurrent.locks.AbstractQueuedSynchronizer;
import org.jspecify.annotations.NullUnmarked;
import org.jspecify.annotations.Nullable;

    @Mock
    private sid_t mockSidT;

    private MsrpcLookupSids lookupSids;
    private jcifs.SID[] testSids;

    @BeforeEach
    void setUp() {
        // Setup is minimal - mocks are configured per test as needed
    }

    @Test
    void constructor_shouldInitializeWithValidParameters() {
        // Arrange
        jcifs.SID mockSid1 = mock(jcifs.SID.class);

    @Mock
    private CommonServerMessageBlockRequest splitRequest;

    @Mock
    private CommonServerMessageBlockRequest cancelRequest;

    @BeforeEach
    void setUp() {
        // Reset mocks before each test
        reset(request, nextRequest, splitRequest, cancelRequest);
    }

    @Test
    @DisplayName("Test isResponseAsync returns true when response is async")
    void testIsResponseAsyncTrue() {

        assertEquals("Malformed PAC", exception.getMessage());
    }

    @Test
    @DisplayName("Test getters return expected values using mocks")
    void testGetters() throws Exception {
        // Use mocking to test getters without complex PAC data creation
        PacLogonInfo logonInfo = mock(PacLogonInfo.class);

        // Setup mock responses

    void equalsAndHashCode_consistency(byte[] id1, byte[] id2, long treeId, boolean expectEqual) {
        lenient().when(cfg.isTraceResourceUsage()).thenReturn(false);

        // Prepare two separate tree mocks but with same tree id
        SmbTreeHandleImpl tA = mock(SmbTreeHandleImpl.class);
        SmbTreeHandleImpl tB = mock(SmbTreeHandleImpl.class);
        lenient().when(tA.acquire()).thenReturn(tA);

        lenient().when(cifsContext.getConfig()).thenReturn(config);
    }

    @AfterEach
    void teardown() {
        // No global state to reset beyond mocks
    }

    static Stream<String> wildcardProvider() {
        return Stream.of(null, "", "*");
    }

    @ParameterizedTest
    @MethodSource("wildcardProvider")

    assertEquals(0, cms.count("a"));
    assertTrue(cms.removeExactly("b", 2));
    assertEquals(1, cms.count("b"));
  }

  public void testIteratorRemove_actualMap() {
    // Override to avoid using mocks.
    multiset = ConcurrentHashMultiset.create();

    multiset.add(KEY);
    multiset.add(KEY + "_2");
    multiset.add(KEY);

    int mutations = 0;

	// works, but only when running one binary at a time.
	// Use a file lock to make sure only one wrapper is running at a time.
	//
	// The lock file is never deleted, to avoid concurrent locks on distinct
	// files with the same path.
	lockName := filepath.Join(os.TempDir(), "go_ios_exec-"+deviceID+".lock")
	lock, err = os.OpenFile(lockName, os.O_CREATE|os.O_RDONLY, 0666)
	if err != nil {
		return 1, err
	}

    }

    @BeforeEach
    public void setUp() throws UnknownHostException {
        ntlmSsp = new NtlmSsp();

        // Use lenient stubbing to avoid UnnecessaryStubbing errors for tests that don't need all mocks
        lenient().when(mockCifsContext.getConfig()).thenReturn(mockConfig);
        lenient().when(mockConfig.getDefaultDomain()).thenReturn("DOMAIN");
        lenient().when(mockConfig.isUseUnicode()).thenReturn(true);
