Diagnostics and Testing

HexView currently ships without a dedicated automated test project, so practical validation usually means:

building the library and sample apps
running the sample views against real binary files
verifying search, edit, save, diff, and annotation paths manually

Useful Diagnostics Targets

file reopen and dispose flows
overwrite versus insert behavior
chunk-boundary search behavior
diff recomputation after edits
annotation load, save, and drag synchronization

Good Next Steps

If you expand test coverage later, the highest-value targets are:

HexSearchService
ByteOverlay
EditJournal
HexAnnotationStorage
control-level selection and editing gestures
