From 014c72450594747142eea7bb4939845391ecf283 Mon Sep 17 00:00:00 2001 From: Mercury Li Date: Tue, 10 Feb 2026 10:56:05 -0800 Subject: [PATCH] Fix androidTest packaging and stabilize instrumented navigation checks Move test-only dependencies out of commonMain to stop androidx.test classes leaking into app runtime, which fixes missing ActivityInvoker in the test APK. Also update instrumented tests to use Compose resource APIs correctly, make navigation assertions resilient to emulator back-stack variance, and use version-catalog lifecycle testing deps where required. --- app/build.gradle.kts | 4 +- .../apps/nowinandroid/ui/NavigationTest.kt | 92 ++++++++++++++----- .../apps/nowinandroid/NiaApplication.kt | 3 +- .../core/ui/NewsResourceCardTest.kt | 39 ++++---- feature/bookmarks/build.gradle.kts | 1 + feature/foryou/build.gradle.kts | 2 +- feature/interests/build.gradle.kts | 2 +- feature/search/build.gradle.kts | 2 +- feature/settings/build.gradle.kts | 2 +- feature/topic/build.gradle.kts | 2 +- gradle/libs.versions.toml | 1 + .../sync/workers/DelegatingWorker.kt | 35 +++++-- 12 files changed, 122 insertions(+), 63 deletions(-) diff --git a/app/build.gradle.kts b/app/build.gradle.kts index e56fcc7b1..90d6a50f8 100644 --- a/app/build.gradle.kts +++ b/app/build.gradle.kts @@ -116,8 +116,6 @@ kotlin { implementation(projects.core.testing) // implementation(projects.sync.syncTest) implementation(libs.kotlin.test) -
