e2e framework benchmark — ios 2026-10-25

Fairness rules
- Same
.appfor every framework (sha256 recorded above) - Zero LLM calls
- Same assertions per canonical test id
- Same retry helpers (dropped first tap, dropped deep link, system alerts)
- Fresh app launch per test
retries=0- Frameworks run sequentially
caffeinate -dimsheld for the run- Warm medians exclude rep 1 (cold)
- Machine-readable reporters only
- Host otherwise idle; load average recorded
- Android
simcounts the app and every framework's on-device helpers (uiautomator, instrumentation runners, agent-device, Argent, warden-uiad), matched case-insensitively - Host processes are tracked by pid and start time, so a reused pid is never counted
- Android animation scales are reset to the device's original values before every framework and restored at the end
Summary
| Framework | Status | Version | Suite median (warm) | p95 | Ratio | Cold rep 1 | Cold-start cost | Prepare | Teardown | Overhead | Pass rate | Flake | Residue | Footprint (LOC / deps) |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| warden | ✓ ok | bun 1.3.14 + warden-e2e | 91.89 s | 94.65 s | 1.00× | 89.75 s | none (rep 1 not slower, -1.35 s) | 800 ms | 76 ms | 94 ms | 100% | 0% | 0 proc / 0 app / 0 path | 379 LOC / 0 B |
Warm suite wall time
- warden
Bar = warm median. Whisker = p95. Dot = cold rep 1. Lower is faster; ratios are against the fastest framework.

Median per test
- warden
Spread across warm reps
Whisker = min to max. Shaded box = min to p95. Tick = median. A distribution carries no quartiles, so the box is not an interquartile range.
Per-step latency
- warden
Whisker = min to max. Shaded box = min to p95. Tick = median. Only frameworks that report steps appear.
| Framework | Steps | Median | p95 | Max |
|---|---|---|---|---|
| warden | 504 | 107 ms | 3.95 s | 5.19 s |

Memory
| Framework | Scope | CPU-s / rep | CPU avg | CPU peak | RSS avg | RSS peak |
|---|---|---|---|---|---|---|
| warden | host | 3.79 s | 2.9% | 41.8% | 146.1 MB | 177.6 MB |
| warden | sim | — | 164.0% | 822.3% | 33.3 GB | 33.5 GB |
CPU-s / rep is the host CPU time of the timed run (warm median) and the headline. CPU avg and peak are ps %cpu, a decaying average on macOS: they move with suite length, do not judge on them.
Where the CPU goes
One table per framework, from the warm-median rep's timed run (the rep whose host CPU-seconds is the lower median). Rows are processes grouped by label (top 12 per scope, the rest in other); host is the framework's own process tree, sim the simulator's launchd_sim tree (iOS only). Share is of the scope's CPU-seconds. RSS is the label's summed RSS per 500 ms tick (0 where it had no process). Spawns counts distinct pids a tick saw: a process that lives between two ticks is only seen through the (exit charge) rows (CPU of a child the bench ran, booked at its exit), so many short-lived xcrun simctl calls read low in Spawns and in CPU.
