Add unit tests for parsing functions in `cmd/status/view_test.go`:
- `parseInt`: parses integers from strings with padding/decimals
- `parseRefreshRate`: parses display refresh rates from system output
- `isNoiseInterface`: filters noise network interfaces
- `parsePMSet`: parses macOS pmset battery output
Coverage for `cmd/status` improved from 8.4% to 12.6%.
Add unit tests for utility functions in cmd/status/view_test.go:
- formatRate: MB/s rate formatting with adaptive precision
- shorten: string truncation with ellipsis
- humanBytesShort: byte formatting with binary units
Add unit tests for heap implementations in cmd/analyze/heap_test.go:
- entryHeap: min-heap for dirEntry (basic ops, empty, single element)
- largeFileHeap: min-heap for fileEntry (basic ops, top N pattern)
- Replace parentheses with commas for supplementary info
- Use commas instead of em-dashes for separators
- Update bullet points from - to * in some contexts
- Improve version extraction regex with fallback logic
Add comprehensive test coverage for the RingBuffer circular buffer
data structure used in network history tracking.
Test cases:
- Constructor initialization (NewRingBuffer)
- Empty buffer returns nil slice
- Adding elements within capacity
- Exact capacity boundary
- Wrap-around behavior with chronological ordering
- Multiple wrap-arounds stress test
- Single-element buffer edge case
- Slice returns independent copy (not reference)
- Disable sensors data collection (CPU temp already shown in CPU card)
- Remove unused sensor-related functions (collectSensors, prettifyLabel, hasSensorData, renderSensorsCard)
- Remove unused gopsutil/sensors import
- Fix inline spinner disown call with explicit PID
- Update version from 1.22.0 to 1.22.1
- Update SECURITY_AUDIT.md to match new version and date
- Fix display of invalid large values like 18446744073709544W
- macOS ioreg returns negative values as uint64 (two's complement)
- Detect overflow pattern (value > 2^63) and convert to signed
- Validate reasonable power range (-200W to 200W) for battery
- Add range validation for SystemPower (0 to 1000W)
Root cause: During charging, battery power is negative but ioreg
formats it as unsigned uint64, causing overflow. This fix properly
converts these values back to signed integers.
- Restore performance test threshold to 200ms (from 500ms)
User caching is highly effective (~8ms for 100 calls)
- Add unit tests for colorizeTemp() covering thresholds and edge cases
