There are some scenarios where you might want to override a dependency during testing.

You don't want the original dependency to run (nor any of the sub-dependencies it might have).

Instead, you want to provide a different dependency that will be used only during tests (possibly only some specific tests), and will provide a value that can be used where the value of the original dependency was used.

### Use cases: external service { #use-cases-external-service }

        // Verify it returns a clone, not the original
        password[0] = 'X';
        char[] password2 = authenticator.getPasswordAsCharArray();
        assertNotEquals(password[0], password2[0], "Should return a clone, not the original");
    }

    @Test
    public void testPasswordConstructorWithCharArray() {

        NtlmPasswordAuthenticator original = new NtlmPasswordAuthenticator("DOMAIN", "testuser", testPassword);

        NtlmPasswordAuthenticator cloned = original.clone();

        // Verify cloned values
        assertEquals(original.getUserDomain(), cloned.getUserDomain());
        assertEquals(original.getUsername(), cloned.getUsername());
        assertEquals(original.getPassword(), cloned.getPassword());

        SmbOperationException original = new SmbOperationException(SmbOperationException.ErrorCode.CONNECTION_TIMEOUT, "Timeout");
        original.withContext("attempt", 1);

        // When
        SmbOperationException retry = SmbOperationException.forRetry(original, 2);

        // Then
        assertEquals(original.getErrorCode(), retry.getErrorCode());
        assertEquals(original.getMessage(), retry.getMessage());

    }

    public void testHandleGuidRoundTrip() {
        HandleGuid original = new HandleGuid();
        byte[] bytes = original.toBytes();
        HandleGuid reconstructed = new HandleGuid(bytes);

        assertEquals(original, reconstructed);
        assertEquals(original.toString(), reconstructed.toString());

The **proxy** intercepts the original client request and adds the special *forwarded* headers (`X-Forwarded-*`) before passing the request to the **application server**.

These headers preserve information about the original request that would otherwise be lost:

* **X-Forwarded-For**: The original client's IP address
* **X-Forwarded-Proto**: The original protocol (`https`)
