From 4840636d26e93678267b9582fab1f9c94c744034 Mon Sep 17 00:00:00 2001 From: janetpius-cmd Date: Sat, 29 Aug 2026 22:06:06 +0100 Subject: [PATCH 1/4] a11y: guard minimum touch target size (Issue: touch target audit) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fix VaultCard's StatusChip (the dense row called out in the issue) to meet the 48x48dp Android minimum touch target by wrapping it in a Box(Modifier.sizeIn(minWidth/minHeight = 48.dp)). Audit the rest of Screens.kt and Views.swift interactive controls (IconButtons, notification actions, iOS toolbar buttons) and document findings in docs/touch-target-audit.md — all were already compliant. Add an automated regression guard: AccessibilityScanTest.kt runs the Android Accessibility Test Framework (ATF) via Espresso's AccessibilityChecks against VaultListScreen, wired into a new accessibility-scan CI job in android-ci.yml so a shrinking tap target fails the build instead of being caught manually later. --- .github/workflows/android-ci.yml | 53 +++++++++++++++++++ android/app/build.gradle.kts | 5 ++ .../ethosprotocol/AccessibilityScanTest.kt | 51 ++++++++++++++++++ .../com/ethosprotocol/ui/screens/Screens.kt | 19 +++++-- docs/touch-target-audit.md | 25 +++++++++ 5 files changed, 148 insertions(+), 5 deletions(-) create mode 100644 android/app/src/androidTest/java/com/ethosprotocol/AccessibilityScanTest.kt create mode 100644 docs/touch-target-audit.md diff --git a/.github/workflows/android-ci.yml b/.github/workflows/android-ci.yml index 1ac75ae..9f418e5 100644 --- a/.github/workflows/android-ci.yml +++ b/.github/workflows/android-ci.yml @@ -264,3 +264,56 @@ jobs: name: android-instrumented-test-reports path: android/app/build/reports/androidTests/connected if-no-files-found: ignore + + # --------------------------------------------------------------------------- + # Automated accessibility scanner: runs the Android Accessibility Test + # Framework (ATF) via Espresso's AccessibilityChecks against AccessibilityScanTest, + # which asserts every interactive control on VaultListScreen (including + # VaultCard's StatusChip) meets the 48x48dp minimum touch target size. + # Kept as its own job so an a11y regression is clearly attributable in the + # PR checks list rather than buried in the general instrumented-tests run. + # --------------------------------------------------------------------------- + accessibility-scan: + runs-on: ubuntu-latest + steps: + - uses: actions/checkout@v4 + + - name: Set up JDK 17 + uses: actions/setup-java@v4 + with: + distribution: temurin + java-version: "17" + + - name: Set up Android SDK + uses: android-actions/setup-android@v3 + + - name: Set up Gradle + uses: gradle/actions/setup-gradle@v4 + + - name: Grant execute permission for gradlew + run: chmod +x gradlew + + - name: Enable KVM group perms + run: | + echo 'KERNEL=="kvm", GROUP="kvm", MODE="0666", OPTIONS+="static_node=kvm"' \ + | sudo tee /etc/udev/rules.d/99-kvm4all.rules + sudo udevadm control --reload-rules + sudo udevadm trigger --name-match=kvm + + - name: Run accessibility scanner (ATF) + uses: reactivecircus/android-emulator-runner@v2 + with: + api-level: 34 + arch: x86_64 + target: aosp_atd + profile: Nexus 6 + disable-animations: true + script: cd android && ./gradlew connectedDebugAndroidTest -Pandroid.testInstrumentationRunnerArguments.class=com.ethosprotocol.AccessibilityScanTest + + - name: Upload accessibility scan report + if: always() + uses: actions/upload-artifact@v4 + with: + name: android-accessibility-scan-report + path: android/app/build/reports/androidTests/connected + if-no-files-found: ignore diff --git a/android/app/build.gradle.kts b/android/app/build.gradle.kts index ecdab77..573eefc 100644 --- a/android/app/build.gradle.kts +++ b/android/app/build.gradle.kts @@ -275,4 +275,9 @@ dependencies { // @HiltAndroidTest / HiltAndroidRule, used by the instrumented tests under androidTest/. androidTestImplementation(libs.hilt.android.testing) kspAndroidTest(libs.hilt.compiler) + // Espresso accessibility-checks module + the Android Accessibility Test Framework (ATF) + // itself, used by AccessibilityScanTest to guard minimum touch target size (and other a11y + // checks) in CI. + androidTestImplementation("androidx.test.espresso:espresso-accessibility:3.6.1") + androidTestImplementation("com.google.android.apps.common.testing.accessibility.framework:accessibility-test-framework:4.0.0") } diff --git a/android/app/src/androidTest/java/com/ethosprotocol/AccessibilityScanTest.kt b/android/app/src/androidTest/java/com/ethosprotocol/AccessibilityScanTest.kt new file mode 100644 index 0000000..6ced279 --- /dev/null +++ b/android/app/src/androidTest/java/com/ethosprotocol/AccessibilityScanTest.kt @@ -0,0 +1,51 @@ +package com.ethosprotocol + +import androidx.compose.ui.test.junit4.createComposeRule +import androidx.test.espresso.accessibility.AccessibilityChecks +import com.ethosprotocol.ui.screens.VaultListScreen +import com.ethosprotocol.ui.theme.EthosProtocolTheme +import dagger.hilt.android.testing.HiltAndroidRule +import dagger.hilt.android.testing.HiltAndroidTest +import org.junit.Before +import org.junit.Rule +import org.junit.Test + +/** + * Automated accessibility-scanner guard (Issue: "No automated check currently guards against + * interactive controls ... shrinking below the standard minimum touch target size"). + * + * Uses the Android Accessibility Test Framework (ATF), wired through Espresso's + * `AccessibilityChecks.enable()`, which runs a suite of checks (touch target size, contrast, + * speakable text, etc.) against every view hierarchy touched during the test.

The banner being labeled only covered the case where it's already visible on first render; a transition while the screen is open needs an explicit announcement call. Add a checklist item to docs/manual-qa-checklist.md's TalkBack/ VoiceOver pass to verify both directions of the transition announce correctly, and note that the WebSocket connection-status indicator proposed in #254 doesn't exist yet but should reuse this pattern. docs/offline-banner-live-region-readme.md documents why this stays a manual check rather than an automated test. --- .../com/ethosprotocol/ui/screens/Screens.kt | 17 +++++++++ docs/manual-qa-checklist.md | 10 ++++++ docs/offline-banner-live-region-readme.md | 36 +++++++++++++++++++ ios/EthosProtocol/Sources/Views/Views.swift | 10 ++++++ 4 files changed, 73 insertions(+) create mode 100644 docs/offline-banner-live-region-readme.md diff --git a/android/app/src/main/java/com/ethosprotocol/ui/screens/Screens.kt b/android/app/src/main/java/com/ethosprotocol/ui/screens/Screens.kt index 37eb387..cab56a1 100644 --- a/android/app/src/main/java/com/ethosprotocol/ui/screens/Screens.kt +++ b/android/app/src/main/java/com/ethosprotocol/ui/screens/Screens.kt @@ -216,6 +216,23 @@ fun VaultListScreen( LaunchedEffect(Unit) { vm.load() } + // #a11y-live-region: OfflineBanner being present/labeled is not enough — TalkBack only + // announces a view when it first appears or when an explicit accessibility event fires. + // Toggling isOffline swaps the banner's presence but, without this, that swap is silent to a + // screen-reader user unless they happen to be scrolled to that part of the list.
