# TopManager — Testing Process
|
||||
|
||||
This document defines the repeatable test process used while evolving TopManager.
|
||||
Every feature increment must pass all five gates below before it is considered done.
|
||||
|
||||
## Gate 1 — Compile
|
||||
```bash
|
||||
scripts/test.sh build
|
||||
```
|
||||
Fast feedback that the code compiles for `platform=macOS,arch=arm64`. First gate on every change.
|
||||
|
||||
## Gate 2 — Unit tests (automated, self-run)
|
||||
```bash
|
||||
scripts/test.sh test # or: xcodebuild ... test
|
||||
```
|
||||
Pure-logic is covered by XCTest in `TopManagerTests/` using `@testable import TopManager`.
|
||||
The suite intentionally targets deterministic logic (no live system state):
|
||||
|
||||
- **Formatting / model math** — bytes, rates, percentages, uptime, usage %.
|
||||
- **MetricsStore** — ring-buffer trim, persistence round-trip, downsampling per range.
|
||||
- **Energy heuristic** — score is monotonic in CPU and wakeups, clamped to 0–100.
|
||||
- **Alert engine** — threshold crossings fire/clear correctly, sustained-window logic,
|
||||
de-duplication (no alert storms), severity ordering.
|
||||
- **Health score** — 0–100, decreases with pressure/thermal/swap/disk load.
|
||||
- **Battery math** — time-remaining and capacity-health formatting.
|
||||
|
||||
Tests must stay hermetic: no sleeping on real timers, no asserting on live CPU numbers.
|
||||
|
||||
## Gate 3 — Runtime smoke test (self-run on this machine)
|
||||
Launch the built app, drive real load, confirm no crash and data populates.
|
||||
```bash
|
||||
# build a runnable .app
|
||||
xcodebuild -project TopManager.xcodeproj -scheme TopManager -configuration Debug \
|
||||
-destination 'platform=macOS,arch=arm64' build CODE_SIGNING_ALLOWED=NO
|
||||
APP=$(find ~/Library/Developer/Xcode/DerivedData/TopManager-*/Build/Products/Debug -name TopManager.app | head -1)
|
||||
open "$APP"
|
||||
# generate CPU load in the background, then verify TopManager surfaces it
|
||||
yes > /dev/null & LOAD=$!; sleep 8; kill $LOAD
|
||||
```
|
||||
Verify: process list shows the load generator near the top, charts move, no crash in
|
||||
`Console`/stderr, menu bar updates, alerts fire when thresholds are crossed.
|
||||
|
||||
## Gate 4 — Ground-truth cross-checks
|
||||
TopManager's numbers are validated against OS tools so we don't ship wrong data:
|
||||
|
||||
| TopManager metric | Ground truth command |
|
||||
|------------------------|---------------------------------------------|
|
||||
| Per-process CPU/mem | `ps -Ao pid,pcpu,pmem,comm -r | head` |
|
||||
| System memory | `vm_stat`, `sysctl vm.swapusage` |
|
||||
| Disk volumes / free | `df -h` |
|
||||
| Battery / power | `pmset -g batt`, `ioreg -rn AppleSmartBattery` |
|
||||
| Thermal state | `pmset -g therm` |
|
||||
| Network throughput | `netstat -ib` |
|
||||
|
||||
Small deltas are expected (sampling windows differ); order-of-magnitude or ranking
|
||||
mismatches are bugs.
|
||||
|
||||
## Gate 5 — Regression: original features intact
|
||||
Manually confirm each shipped feature still works: Processes (sort/search/kill/suspend/
|
||||
resume), Apps (activate/hide/quit/force-quit/copy bundle id), Performance (CPU/Mem/Net
|
||||
charts), Power & Storage (system/GPU/storage/network), and the menu-bar readout.
|
||||
|
||||
## Loop
|
||||
```
|
||||
implement slice → Gate 1 → Gate 2 → Gate 3 → Gate 4 → Gate 5 → checkpoint commit
|
||||
```
|
||||
Repeat per increment until the value rubric in `docs/VALUE_PLAN.md` is met.

# TopManager — 10× Value Plan
|
||||
|
||||
## Thesis
|
||||
TopManager today is a polished, **read-only Activity Monitor clone**: it *shows* numbers.
|
||||
Its value ceiling is "I can see what's using my Mac and kill a process."
|
||||
|
||||
To make it ~10× more valuable we move it from **viewer → system-intelligence & control
|
||||
center**: it watches the system for you, remembers its history, explains problems, exposes
|
||||
data Activity Monitor hides, and lets you act — including always-on from the menu bar.
|
||||
|
||||
All existing features are preserved (several are improved).
|
||||
|
||||
## Value rubric (capability scoring)
|
||||
| Dimension | Before | After (target) |
|
||||
|---|---|---|
|
||||
| Per-process depth | CPU, mem, threads, state | + disk I/O rate, energy impact, args, open files, full path, tree |
|
||||
| Time memory | 60 in-RAM points, lost on quit | persistent history, minutes → 24h, survives restart |
|
||||
| Proactivity | none | threshold alerts + native notifications + health score + diagnosis |
|
||||
| Energy / battery | **absent** | battery health (cycles/condition/capacity) + per-process energy |
|
||||
| Always-on surface | bare "12%" | rich menu-bar HUD: CPU/RAM/net + top consumers + quick-kill |
|
||||
| Customization | none (all hardcoded) | Settings: refresh rate, menu metric, thresholds, launch-at-login |
|
||||
|
||||
## Increments
|
||||
0. **Test harness** — XCTest target, `@testable import`, 5-gate process. ✅
|
||||
1. **Persistent history** — `MetricsStore` ring buffer on disk; 1m/5m/1h/24h charts.
|
||||
2. **Deep per-process data** — disk I/O, energy impact, args, open files, path; surface the
|
||||
(currently unused) `ProcessDetailView` as a real inspector; new sortable columns.
|
||||
3. **Battery + energy** — IOKit `PowerMonitor`; Energy/Battery UI; menu-bar battery.
|
||||
4. **Alerts + health** — `AlertEngine`, `UserNotifications`, in-app inbox, 0–100 health score,
|
||||
"why is my Mac slow?" diagnosis.
|
||||
5. **Settings + rich menu bar** — configurable refresh/metric/thresholds, launch-at-login
|
||||
(`SMAppService`), menu-bar HUD with top consumers + quick actions.
|
||||
6. **Verification** — full test run, runtime smoke, ground-truth cross-checks, sign, commit.
|
||||
|
||||
## Non-negotiables
|
||||
- Never break a shipped feature (regression Gate 5).
|
||||
- No new entitlements / no root / no privileged helper — must run & sign as-is.
|
||||
- Every increment passes all five gates in `docs/TESTING.md` before moving on.
