WalkthroughThe PiP tests now use a Robolectric-created activity and real package-manager feature flags. Tests assert actual activity PiP state for supported, pre-Oreo, and unsupported-device scenarios. ChangesPicture-in-picture test updates
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The PR replaces flaky Android context mocking with a Robolectric activity, reducing CI setup failures. Merge readiness is moderate because the test still needs to use the repository-required test base and verify the exact PiP parameters rather than only mode entry and non-null values.

for this fast unit-test scope, preserving its existing test behavior and setup.
- Around line 73-75: Update the PictureInPictureTest entry and helper assertions
to retrieve parameters via Activity.getPictureInPictureParams(), then assert the
configured aspect ratio with getAspectRatio() and, on SDK S+, the expected
isAutoEnterEnabled() value. Do not rely on ShadowActivity for parameter access,
and retain the existing mode assertion.

The connecting progress bar covers the same call join round-trip as waitForCallToStart, which can exceed 10s on a loaded CI emulator. This is the assertConnectingView failure seen on PR #1781.

Flake fix is right and I'd land it — @Before mocked the whole PictureInPictureKt file class while @After unmocked ContextCompat::class, so the instrumentation leaked across the JVM fork. Ran the class 5x plus the full module suite, all green.
My comments are about the assertions, not the fix, and build on the resolved thread rather than reopening it. All found by mutation: gutting getPictureInPictureParams to return PictureInPictureParams.Builder() leaves 9 of the 10 tests green.
Two non-blocking notes, on lines outside the diff so I couldn't inline them:
- Pre-existing: the
getAspecttests passActivityInfo.SCREEN_ORIENTATION_*, but production feedsConfiguration.ORIENTATION_*. Portrait matches by coincidence (both1); real landscape (2) is never tested. Same behaviour either way, just the wrong contract. - Description says "All 9 tests pass"; the second commit made it 10.
|
Thanks for the mutation pass, all four comments are addressed in 308ca0c. Also acted on the two notes from the review body: the getAspect tests now pass Configuration.ORIENTATION_* (production still compares against ActivityInfo.SCREEN_ORIENTATION_PORTRAIT, which has the same value, so behavior is unchanged; happy to fix that contract in a follow-up), and the description now says 10 tests. |
* [AND-1445] Stabilize the flaky E2E emulator tests The nightly E2E cron was red on 11 of the last 13 runs. Most failures came from retry attempts that were not independent: the instrumentation runs inside the app process, so a failed attempt could leave the internet connection disabled or a call still active, and the remaining attempts inherited that state and failed the same way. - RetryRule now restores the connection and leaves any leftover call between attempts, and all post-failure steps are best-effort so an attachment error cannot replace the real failure or skip retries. - The UiAutomator wait helpers are replaced with the polling, stale-safe versions from stream-chat-android. Timeouts now throw a clear error naming the selector instead of an NPE. - All UserRobot clicks go through the new stale-safe waitToAppearAndClick. - Longer windows for joining a call and for the outgoing ringing screen, and the recording label assertion polls through the reconnect banner. - run_e2e_test accepts a test_class option, and the PR workflow exposes api_level and test_class dispatch inputs to sample one flaky test. - Failure artifacts include allure-results, and the E2E concurrency groups are scoped by workflow name. * [AND-1445] Address review findings and widen the view menu wait - Pass test_class to fastlane through the step environment with a quoted expansion, so the dispatch input cannot inject shell commands into the emulator action script. - Drop '$' from the allowed test_class characters: the local and device shells would expand it. All E2E test classes are top-level anyway. - Give the view menu items in setView a 15s window. In the failed batch 0 run, the Spotlight item was present in the hierarchy dump seconds after the 5s timeout: with many live video tiles the popup lands in the accessibility tree late on the emulator. * [AND-1445] Widen the connecting screen window to match the join window The connecting progress bar covers the same call join round-trip as waitForCallToStart, which can exceed 10s on a loaded CI emulator. This is the assertConnectingView failure seen on PR #1781.

Goal
Fix the flaky
PictureInPictureTest > should enter pip mode with correct paramstest. It fails intermittently on CI duringsetupwith:The failure is a race in MockK's inline agent when it proxies platform classes. The test shares its JVM with the Paparazzi snapshot tests, which append to the bootstrap classpath, and that combination makes the agent attach unreliable on the Linux runners. Seen on PR #1776, where the diff was test-only.
Resolves AND-1446.
Implementation
The test class already runs with Robolectric, so the platform classes do not need to be mocked at all:
mockk<Context>()with a real RobolectricActivity(Robolectric.buildActivity(Activity::class.java).create().get()). Since the context is itself anActivity,findActivity()resolves it naturally, so themockkStatic("...PictureInPictureKt")call is gone too.shadowOf(activity.packageManager).setSystemFeature(...)instead of mockedPackageManagerandResources.activity.isInPictureInPictureMode. Robolectric'sShadowActivitysets that flag in bothenterPictureInPictureModeoverloads (verified in the Robolectric 4.11.1 shadow source).Call,ScreenSharingSession,ParticipantState).tearDownnow only callsclearAllMocks(); the oldunmockkStatic(ContextCompat::class)was unmocking something that was never mocked.With no inline-agent proxying of
android.content.Context, the race that caused the flake cannot happen anymore.After review, the assertions were strengthened:
getPictureInPictureParamstests assert the built params values where the runtime allows it:isAutoEnterEnabledon S and above, plus aspect ratio and title on TIRAMISU (getAspectRatio()returnedfloatuntil API 32, so it can only be asserted from 33).setAutoEnterEnabledcall in production fails the tests.getAspecttests passConfiguration.ORIENTATION_*, the values production actually feeds, instead ofActivityInfo.SCREEN_ORIENTATION_*.🎨 UI Changes
No UI changes, this is a test-only change.
Testing
Run the test class locally:
All 10 tests pass (0 failures, 0 skipped).
