Test suite for Issue #150: .mdz (Markdown Zip) format implementation.
|
|
|
|
This test module covers the .mdz ZIP-based format functionality:
|
|
- ZIP container creation and extraction
|
|
- Asset embedding (images, CSS, etc.)
|
|
- Manifest.json generation and parsing
|
|
- Path rewriting for embedded assets
|
|
- Compression optimization
|
|
- Cross-platform compatibility
|
|
- Integrity validation
|
|
|
|
These tests follow the TDD8 methodology and should initially fail until
|
|
the corresponding implementation is created.
