There was a problem hiding this comment.
The comment says "150 lines" but the actual array creates 148 lines (5 initial + 140 dependencies + 3 final). Is this intentional, or should we fix either the comment or the actual line count?

This variable is created but never used in the test. Could we remove it to keep the test cleaner?

Consider adding test cases for edge scenarios:
- Empty JSON files
- Malformed JSON
- Files with only whitespace/comments
- What happens when truncation cuts off mid-JSON structure?
These would help ensure the truncation feature is robust across all scenarios.

Consider extracting these magic numbers into named constants at the top of the file:
This would make the tests more maintainable and the intent clearer.

Summary
This PR adds comprehensive tests to verify that JSON file truncation is working correctly when the
maxReadFileLinesetting is configured.Context
Issue #8149 reported that JSON files were not being truncated properly even when a 50-line limit was set. After investigation and adding comprehensive tests, I found that the truncation feature is actually working correctly for JSON files.
Changes

All tests pass successfully, confirming that the JSON file truncation feature is working as expected:
Conclusion
The tests demonstrate that the truncation feature is functioning correctly for JSON files. The issue reported might be:
