Description

This PR runs the maestro flows split across 2 devices per job on both platforms, cutting the e2e step from roughly 10 minutes to 5 on each. It also folds the restart check into the sign-in flow, so one fewer native sign-in runs per job.

Also simplified the workflow and job names

📝 Walkthrough

Walkthrough

The pull request hardens Expo native E2E execution. It adds sign-out status reporting and restart-session assertions. It provisions multiple iOS simulators and Android emulators. It runs Maestro flows across shards, parses JUnit results, reruns failed flows, and reports flaky outcomes. CI now installs a pinned Maestro archive, collects per-device logs, scrubs credentials on all runs, and uploads artifacts.

Priority: ⬇️ Low

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 7682e

The sharded E2E workflow still carries unresolved security, reliability, and CI-performance risks that should be addressed before merge.

Clear the password field before input.

Maestro 2.8.0 inputText appends to existing text. If password autofill prepopulates this field, the flow submits the wrong password and has no password-step retry. Select all and delete the existing value before inputText.

Comment thread integration/tests/expo-native/run-flows.sh
Each e2e job now boots two devices and runs the flows once with
--shard-split across them, then reruns only the flows the JUnit report
marked failed. That keeps the per-flow retry while paying Maestro's
startup once instead of once per flow. Two iPhone 17 Pro simulators on
the 6 vCPU macOS runner halved the flow phase, 549s to 274s.

The simulators boot right after checkout so they settle during the
native build, and the keyboard and animation defaults move into
boot-ios-simulators.sh, which replaces the simulator action. On Android
run-android-flows.sh starts the extra emulator as a read-only instance
of the booted AVD. MAESTRO_SHARDS sets the device count for both.
session-persists-across-restart was sign-in.yaml with a stop and
relaunch inserted before the JS sign-out, so the restart now lives in
sign-in.yaml and the duplicate flow is gone. Every assertion survives in
the order it ran before; one full sign-in fewer per run.

The identifier eraseText drops from 100 to 60, which still covers the
CI addresses, and the password field no longer erases at all since it
has never held a value. Maestro erases one character at a time, so the
count is the cost.
The failed-only rerun decided the result, so a flow that failed and then
passed left the check green. The rerun now only labels a failure flaky or
deterministic in the summary, and any first-attempt failure fails the step
with an error annotation naming the flow.
Release builds log nothing from JS, so a sign-out that never ran and one
that rejected look the same in the artifacts. The sign-out button now
renders whether signOut is pending, resolved, or rejected with its
message, readable from Maestro screenshots and hierarchies.
simctl bootstatus has no deadline of its own, so a simulator that never
finished booting would hold the job until its 60-minute timeout. The
wait now gives up after 240s, prints the device state, and fails the
step, matching the Android boot wait.
Booting them alongside the build slowed every build-phase step on the
6 vCPU runner and gave back most of the cold-run saving. The boot now
starts once the build is done and overlaps the maestro install and the
BAPI user provisioning instead.

294-300: 🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Clean up simulator log processes on every exit.

The workflow starts one background log stream process per simulator. If simctl install or log setup fails before Line 305, the shell exits without killing already-started processes. Add an EXIT trap that kills and waits for all recorded PIDs so cleanup and artifact upload do not race with leftover log writers.

wobsoriano force-pushed the rob/maestro-ci-hardening branch from 2dc8f49 to 4664b8a Compare September 11, 2026 19:00
Android occasionally kills the freshly started process when pm clear's
task removal lands after am start, leaving a blank screen for the whole
auth-state wait. The launch and that first wait now retry once; every
assertion on app behaviour stays unretried.
…runner

The upload now requires the credential scrub to have succeeded instead
of running on always(). run-flows.sh needs PLATFORM since the device
split, which broke the root package script; it is now one script per
platform, and force-stop targets the default device when MAESTRO_UDID
is unset.
@wobsoriano wobsoriano changed the title test(expo): maestro improvements test(e2e): shard maestro flows across two devices per job Sep 11, 2026
Reads as "Expo / Native E2E (ios, sdk 57)" in the checks list, matching
the "CI / Integration Tests (astro, chrome)" convention, with the
platform first since that is what a red check gets read for.
