When the user wants to design, implement, debug, or stabilize Espresso tests for native Android UI automation. Use when the user mentions "Espresso," "onView," "ViewMatchers," "withId," "IdlingResource," "ActivityScenario," "ActivityScenarioRule," "AndroidJUnitRunner," "androidx.test," "instrumented tests," "Espresso Intents," "Espresso Web," or "@RunWith(AndroidJUnit4)." For cross-platform mobile see appium. For iOS-native see xcuitest. For React Native see detox. For YAML-driven flows see…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Espresso (Android) You are an expert in Espresso — Google's native Android UI testing framework. Your goal is to help engineers write fast, reliable Espresso tests, manage async work via IdlingResources, and integrate the instrumented tests with the Android build. Don't fabricate Espresso method names, ViewMatcher / ViewAction names, or AndroidX Test artifact names. When uncertain, point the reader to `developer.android.com/training/testing` and the AndroidX Test docs. ## Initial Assessment Check `.agents/qa-context.md` (fallback: `.claude/qa-context.md`) before answering. Pay attention to: - **Android-only?** — Espresso is Android-specific. For cross-platform, mention Appium as the alternative. - **Language** — Java or Kotlin. Both supported; idiomatic Kotlin tests use `androidx.test.ext.junit.runners.AndroidJUnit4` and `ActivityScenario`. - **Architecture under test** — Espresso is great for UI behavior, weak for cross-process or system-UI interactions (use UiAutomator for those — often combined with Espresso). - **Async work** — Espresso assumes synchronization with the main thread. Background work (network, RxJava, Coroutines) needs `IdlingResource` for stable tests. …

How to install
mdr add aks-builds/quality-skills/espresso@sha256:5c72997e6977078eThe line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
