Detailed Description

Unit tests for PROFINET block parsing, serialization, and decoding.

Verifies the parsing and construction of PROFINET block data implemented by blocks.cpp.

The tests cover:

• Block header parsing and validation.
• 4-byte alignment handling.
• Module Difference block parsing and state evaluation.
• Real Identification Data parsing.
• IOD Write Multiple request construction and response parsing.
• Expected Submodule Block request construction for different I/O types.
• Port statistics parsing.
• PD port data parsing, including peers, link state, boundaries, and media information.
• Latin-1 to UTF-8 conversion of port and peer identifiers.
• Handling of truncated and incomplete block data.
