server to create representative test cases. Or test that your code survives in
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

    assertEquals(4, list.lastIndexOf("b"));
  }

  public void testCopyOfDefensiveCopy() {
    // Depending on JDK version, either toArray() or toArray(T[]) may be called... use this class
    // rather than mocking to ensure that one of those methods is called.
    class TestArrayList<E> extends ArrayList<E> {
      boolean toArrayCalled = false;

      @Override
      public Object[] toArray() {
        toArrayCalled = true;

    }

    /**
     * Test that both mapping and settings resources can be loaded simultaneously.
     * Verifies no resource contention or locking issues.
     */
    @Test
    public void testResourceLoading_simultaneousAccess() throws Exception {
        String mappings;
        String settings;

        // Load both resources

        // to create the stream handler for the connection.
        URLStreamHandlerFactory mockFactory = mock(URLStreamHandlerFactory.class);

        // Create a concrete URLStreamHandler subclass instead of mocking
        URLStreamHandler mockStreamHandler = new URLStreamHandler() {
            @Override
            protected URLConnection openConnection(URL u) throws IOException {
                return mock(HttpURLConnection.class);

        }
    }

    @Nested
    class AttributeAndStateTests {

        @Test
        public void testGetTypeForFile() throws Exception {
            // Mocking underlying connection and info retrieval is complex.
            // This test focuses on the logic based on the URL structure.
            SmbFile file = new SmbFile("smb1://server/share/file.txt");

                }
            }
            assertTrue(hasNonZero, "Signature should be present at correct offset");
        }

        @Test
        @DisplayName("Should be thread-safe with optimized locking")
        void testSignThreadSafety() throws InterruptedException {
            int threadCount = 10;
            Thread[] threads = new Thread[threadCount];
            byte[][] dataArrays = new byte[threadCount][128];

func TestFailedRefreshLock(t *testing.T) {
	if testing.Short() {
		t.Skip("skipping test in short mode.")
	}

	// Simulate Refresh response to return no locking found
	for i := range lockServers[:3] {
		lockServers[i].setRefreshReply(false)
		defer lockServers[i].setRefreshReply(true)
	}

	dm := NewDRWMutex(ds, "aap")
	dm.refreshInterval = 500 * time.Millisecond

            assertEquals(USER_REALM, ticket.getUserRealm());
        }
    }

    // Note: Testing the code path where keys are null and retrieved from
    // KerberosCredentials requires mocking the constructor of KerberosCredentials,
    // which is not possible with standard Mockito. A tool like PowerMock would be needed.

 * and DI container integration.
 *
 * <p>Thread Safety: This class is thread-safe. Each cached entry holds its own
 * GroovyClassLoader. The cache uses Guava Cache with segment-based locking for
 * lock-free concurrent reads. Each evaluate() call creates a new Script instance
 * to ensure thread isolation of bindings.</p>
 *
 * <p>Note on class-level isolation: Compiled Script classes are cached and reused.
