android_ui_testing

A set of guidelines for testing Android app interfaces with Espresso and Jetpack Compose testing tools. It covers testing user interactions, waiting for asynchronous work, isolating backend services, and running tests on devices or emulators.

In plain words
What is it for?
Use it when writing Android tests for traditional Views or Jetpack Compose screens, especially tests that involve delayed work, user actions, or backend calls.
Why use it?
It keeps interface tests focused and less fragile while ensuring they wait for the app to become ready. Mock servers and test doubles prevent network services from making tests unreliable.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Made for: Cursor.

Per session 10 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 139 The whole file, excluding the scripts and references it only reads on demand.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

android_ui_testing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

  • Use Espresso for testing classic Android Views; use Compose Testing APIs for Jetpack Compose UI.
  • Keep UI tests focused on user interactions and visible UI changes.
  • Avoid complex logic in UI tests; delegate business logic testing to unit tests.
  • Use Idling Resources or composeTestRule.awaitIdle() to synchronize asynchronous events.
  • Use clear, descriptive test names that reflect user behavior being tested.
  • Isolate UI tests from backend dependencies by using mock servers or test doubles.
  • Run UI tests on real or emulated devices to catch platform-specific issues.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

android_ui_testing is a cursor rule published in the GitHub repository nphausg/ai-agent-skills (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 10 tokens to every session and 139 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
