📝 WalkthroughWalkthroughInstrumentation network checks now use active network capabilities and validation status. Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to The connectivity wait may exceed its documented 10-second timeout by up to about two seconds when polling near the deadline, delaying instrumentation failures. This is a bounded, non-blocking risk that should be corrected or explicitly accepted by the owner. Possibly related PRs

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Keep the connectivity wait within timeoutMs.
The fixed sleep(2) can start just before deadline. It then delays the failure by up to two additional seconds. This violates the stated 10-second timeout.
Proposed fix
while (System.currentTimeMillis() < deadline) {
if (isNetworkConnected(connectivityManager) == expectedConnected) return
- sleep(2)
+ val remainingMs = deadline - System.currentTimeMillis()
+ if (remainingMs > 0) {
+ onView(isRoot()).perform(sleep(minOf(2_000L, remainingMs)))
+ }
}📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Product Description
No user-facing changes. Instrumentation test infrastructure only — nothing here ships in the app.
Technical Summary
Two independent fixes to instrumentation test infrastructure, both aimed at flakiness on
BrowserStack.
1.
setNetworkEnabledwaits on real connectivity, not on the Wi-Fi togglesetNetworkEnabledissues three shell commands (svc wifi,wifi_wakeup,svc data) and thenwaited on
WifiManager.isWifiEnabled. That check reads back the setting the first command justwrote, so it returned almost immediately and told us nothing about whether traffic could actually
flow. It also ignored mobile data entirely — a device could return from
setNetworkEnabled(false)with cellular still up.
Replaced with
waitForNetworkConnectivity, which polls the active network's capabilities:This is transport-agnostic, so a single wait covers Wi-Fi and cellular, and
VALIDATEDmeans thedevice has confirmed a working internet path rather than merely an enabled radio. Same 10s timeout
and 2s poll interval as before; the thrown message now names
setNetworkEnabledinstead of thelong-deleted
changeWifi.ACCESS_NETWORK_STATEis already declared in the manifest and is install-time granted, so no newpermissions or
GrantPermissionRuleentries are needed. API 23+ throughout, matchingminSdk.2. Pin BrowserStack device locale to en-US
scripts/browserstack.pynow sendslanguage: en/locale: US. BrowserStack devices otherwisecome up in whatever locale the pool assigns, which breaks any assertion matching on English UI
strings or on date and number formatting.
3. Drive-by: removed the
WifiManagerimport left unused by change 1.Safety Assurance
Safety story
Test-only. Nothing in this PR is compiled into a shipped APK —
InstrumentationUtilitylives inapp/instrumentation-tests, andbrowserstack.pyis CI tooling. Worst case is that instrumentationtests fail or hang, which is visible in CI and cannot reach users or existing data.
Verified locally:
:app:assembleCommcareDebugAndroidTestbuilds cleanktlintFileclean onInstrumentationUtility.ktWorth a reviewer's attention:
waitForNetworkConnectivity(true)requires a validated internet path. On a BrowserStack devicebehind a captive portal or with no working upstream, validation never completes and the helper
throws after 10s instead of returning early as the old Wi-Fi check did. That is the intended
trade — a loud failure beats a test proceeding without network — but it does mean this can surface
environment problems that were previously silent.
setNetworkEnabled, so the blast radius within theinstrumentation suite is wide even though it is zero outside it.
Automated test coverage
No new tests. This is test infrastructure, and the coverage that matters is the existing
BrowserStack suite —
DemoUserOfflineTest,LoginTest,FormEntryTest,MenuTests,ManualQuarantineTestall toggle the network and are the tests that exercise this path.A full BrowserStack run is the real verification and has not been done yet; the offline-behaviour
tests above are the ones to watch, since they are the tests whose flakiness motivated the change.
