A command for Test-Driven Development (TDD), a method where you write a failing test, make it pass with the smallest change, and then improve the code. It also covers Android device and end-to-end tests when needed.

Use it to write tests before new features, reproduce bugs with failing tests, implement fixes, run unit or Android UI tests, and check the full test suite for regressions.

It makes the expected behavior explicit before implementation and provides evidence that a bug is fixed or a feature works without breaking existing behavior.

test — Command for Claude Code by GuillemRoca/agent-skills-android

Install

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.

Clone the repo

git clone --depth 1 https://github.com/GuillemRoca/agent-skills-android

Made for: Claude Code.

Or install agent-skills-android, the plugin that ships this one along with the rest of its 30 skills, 8 commands, 3 agents.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 453 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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00453
Opus 5.5	$0.00000	$0.00181
Sonnet 5.5	$0.00000	$0.00091
Haiku 4.5	$0.00000	$0.00045

Security

Grade A, and why

test 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 1mo 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

/test — Test-Driven Development

Write tests before implementation using Red-Green-Refactor.

Instructions

Load and follow these skills:

test-driven-development from skills/test-driven-development/SKILL.md
android-device-testing from skills/android-device-testing/SKILL.md (for instrumented tests)
android-e2e-verification from skills/android-e2e-verification/SKILL.md (for end-to-end acceptance flows)

New Feature Testing

Write failing test describing the expected behavior
Run test — confirm it FAILS (RED)
Write minimal code to make it pass (GREEN)
Run full suite — ./gradlew test
Refactor while tests stay green
Repeat for next behavior

Bug Fix Testing (Prove-It Pattern)

Write a test that demonstrates the bug
Run test — confirm it FAILS (proves bug exists)
Fix the code
Run test — confirm it PASSES (proves fix works)
Run full suite — ./gradlew test (no regressions)

Test Types

Type	Framework	Command
Unit tests	JUnit5 + MockK	`./gradlew test`
Compose UI tests	Compose test rules	`./gradlew connectedAndroidTest`
Espresso tests	Espresso	`./gradlew connectedAndroidTest`
Room DAO tests	In-memory Room	`./gradlew connectedAndroidTest`
Screenshot tests	Preview Screenshot Testing / Roborazzi	`./gradlew validateDebugScreenshotTest`
E2E acceptance flows	Maestro	`maestro test .maestro/`

Rules

Tests BEFORE implementation (always)
Every test must be seen failing before passing
No Thread.sleep — use advanceUntilIdle() or waitUntil
Mock at boundaries only (DAO, API), not internal classes
Descriptive test names that read like behavior specs

Changes

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.

test is a command published in the GitHub repository GuillemRoca/agent-skills-android (3 stars, last pushed 15d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 453 tokens. 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.
