You can also combine `dataclasses` with other type annotations to make nested data structures.

In some cases, you might still have to use Pydantic's version of `dataclasses`. For example, if you have errors with the automatically generated API documentation.

In that case, you can simply swap the standard `dataclasses` with `pydantic.dataclasses`, which is a drop-in replacement:

    @Test
    @DisplayName("Test initProtocolVersions with strings")
    void testInitProtocolVersionsWithStrings() {
        config.initProtocolVersions("SMB202", "SMB311");

        assertEquals(DialectVersion.SMB202, config.getMinimumVersion());
        assertEquals(DialectVersion.SMB311, config.getMaximumVersion());
    }

    @Test
    @DisplayName("Test initProtocolVersions with null/empty strings")

        assertNotNull(emptyUnicodeStringTrue.buffer, "Buffer should not be null for empty string with zterm");
        assertEquals(1, emptyUnicodeStringTrue.buffer.length, "Buffer length should be 1 for empty string with zterm");
        assertEquals(0, emptyUnicodeStringTrue.buffer[0], "Buffer should contain only zero for empty string with zterm");

        // Test with an empty string and zterm = false

        // ACE.toString() outputs "Inherited " with 1 space
        assertTrue(result.contains("Inherited"));
        assertTrue(result.contains("This folder, subfolders and files"));
    }

    @Test
    @DisplayName("Test appendCol helper method")
    void testAppendCol() {
        StringBuffer sb = new StringBuffer();

        // Test with short string
        ace.appendCol(sb, "test", 10);

        }
    }

    @Test
    @DisplayName("Test decode with non-zero buffer offset")
    void testDecodeWithOffset() throws SMBProtocolDecodingException {
        // Prepare test data with offset
        byte[] buffer = new byte[100];
        int offset = 50;

        // Fill resume key at offset with test pattern
        for (int i = 0; i < 24; i++) {
            buffer[offset + i] = (byte) (0xFF - i);

    public void test_constructor_withNullMessage() {
        // Test with null message
        DataStoreException exception = new DataStoreException((String) null);

        assertNotNull(exception);
        assertNull(exception.getMessage());
        assertNull(exception.getCause());
    }

    public void test_constructor_withNullCause() {
        // Test with null cause

If you don't want to include the `standard` optional dependencies, you can install with `pip install fastapi` instead of `pip install "fastapi[standard]"`.

### Without `fastapi-cloud-cli` { #without-fastapi-cloud-cli }

If you want to install FastAPI with the standard dependencies but without the `fastapi-cloud-cli`, you can install with `pip install "fastapi[standard-no-fastapi-cloud-cli]"`.

        // Test with null cause
        TransportException nullCauseException = new TransportException((Throwable) null);
        assertNull(nullCauseException.getCause());
    }

    @Test
    @DisplayName("Test constructor with message and cause creates exception with both")
    public void testConstructorWithMessageAndCause() {
        // Create exception with both message and cause

public interface Cache<K, V> {

  /**
   * Returns the value associated with {@code key} in this cache, or {@code null} if there is no
   * cached value for {@code key}.
   *
   * @since 11.0
   */
  @CanIgnoreReturnValue // TODO(b/27479612): consider removing this?
  @Nullable V getIfPresent(@CompatibleWith("K") Object key);

  /**

4. **Backward Compatibility**: Must maintain compatibility with SMB2/SMB1

### Mitigation Strategies
1. Implement features behind configuration flags
2. Provide graceful fallback mechanisms
3. Extensive testing with various server configurations
4. Phased rollout with beta testing

## Resource Requirements

### Development Team
- 2-3 Senior Java developers with SMB protocol expertise
- 1 QA engineer for test infrastructure
