Handle missing source in dependencies #72
Conversation
Some GEMs provide functions that internally create their own examples, e.g. rswag's 'run_test!' internally defines examples. In these cases, no source file will be found and even if resolved to the GEM's function, it would make no sense as an execution point.

248-252: LGTM! Consider enhancing the documentation slightly.The guard clause correctly handles cases where GEMs create examples without corresponding source files. The implementation is clean and the comments explain the rationale well.
Consider slightly expanding the comment to clarify the broader impact:
# some Gems provide functions that create their own examples # e.g. rswag's 'run_test!' internally defines examples # in these cases, no source file will be found +# skipping dependency registration in such cases is safe +# as these are external dependencies

248-252: Verify impact on coverage reporting.
While the guard clause correctly handles missing source files, we should verify that skipping these dependencies doesn't impact coverage reporting accuracy.
Let's check for any existing logging of skipped dependencies:
Also, let's verify if similar nil checks exist elsewhere in the codebase:
✅ Verification successful
No coverage impact from skipping missing source files
The nil check for source files is a valid guard clause that properly handles cases where source files cannot be found, particularly for examples generated by gems like rswag. This behavior:
- Is properly documented in the code comments
- Has consistent handling across the codebase:
- In
fetch_changed_files: Reports deleted files when source is nil - In dependency tracking: Safely skips registration for nil sources
- In
- Doesn't impact coverage reporting because:
- Only skips registration of non-existent files
- Coverage filters and reporting systems remain intact for all valid source files
- The reporter still tracks all actual project source files
