Use this skill to write Espresso 3.7.0 tests against Android Views — `onView(matcher).perform(action).check(matches(...))`, `onData(...)` for `AdapterView`, `RecyclerViewActions`, `Intents.intended/intending`, and `IdlingResource` registration. Covers the full `ViewMatchers` / `ViewActions` / `ViewAssertions` catalog, the `RootMatchers.DEFAULT` exclusion of dialogs and popups (the `inRoot(isDialog())` requirement), the `BottomNavigationViewActions` doesn't-exist gotcha in 3.7.0 contrib, and the `PickerActions.setDate(year, month, day)` 1-12 month convention. Use when the user reports `NoMatchingViewException`, `AmbiguousViewMatcherException`, `PerformException`, asks "how do I click in a dialog", "Espresso typeText doesn't fire", "intent stub for camera", or "Espresso vs UiAutomator".

From the source SKILL.md

Espresso is the canonical instrumentation-time UI test framework for Android Views (not Compose — for Compose, use the compose/ skill set; for cross-Compose-View interop see ../../../compose/interop/testing-with-espresso-interop/SKILL.md). Each onView(...).perform(...).check(...) call internally pumps the main looper to idle, finds exactly one matching view, runs the action, and pumps to idle again before checking. This skill encodes the full matcher/action/assertion catalog, the RootMatchers.DEFAULT trap, and the per-version gotchas.

What this skill does

Writing Espresso Tests is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/writing-espresso-tests/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when the user reports `NoMatchingViewException`, `AmbiguousViewMatcherException`, `PerformException`, asks "how do I click in a dialog", "Espresso typeText doesn't fire", "intent stub for camera", or "Espresso vs UiAutomator".
