What it does

Mobile App Testing is an agent skill from secondsky/claude-skills. Mobile app testing with unit tests, UI automation, performance testing. Use for test infrastructure, E2E tests, testing standards, or encountering test framework setup, device farms, flaky tests, platform-specific test errors.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Testing & QA, covering Unit testing, Mobile testing and debugging and Load testing. The repository describes itself as: Production-ready skills for Claude Code CLI - Cloudflare, React, Tailwind v4, and AI integrations. The licence is MIT.

When your agent uses it

Test infrastructure
Testing standards
Encountering test framework setup
Platform-specific test errors

Example prompts

“/mobile-app-testing”

What it can do on your machine

Read from SKILL.md and the folder at commit 8837836. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are javascript, swift and kotlin).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Mobile App Testing loads about 643 tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 79 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~61
When it runs · the whole SKILL.md, loaded when a task matches: ~643

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Mobile App Testing

Implement comprehensive testing strategies for mobile applications.

Testing Pyramid

Level	Tools	Coverage
Unit	Jest, XCTest, JUnit	70%
Integration	Detox, Espresso	20%
E2E	Appium, Detox	10%

React Native (Jest + Detox)

javascript

// Unit test
describe('CartService', () => {
  it('calculates total correctly', () => {
    const cart = new CartService();
    cart.addItem({ price: 10, quantity: 2 });
    expect(cart.getTotal()).toBe(20);
  });
});

// E2E test (Detox)
describe('Login flow', () => {
  beforeEach(async () => {
    await device.reloadReactNative();
  });

  it('should login successfully', async () => {
    await element(by.id('email-input')).typeText('user@example.com');
    await element(by.id('password-input')).typeText('password123');
    await element(by.id('login-button')).tap();
    await expect(element(by.id('dashboard'))).toBeVisible();
  });
});

iOS (XCTest)

swift

func testLoginSuccess() {
    let app = XCUIApplication()
    app.launch()

    app.textFields["email"].tap()
    app.textFields["email"].typeText("user@example.com")
    app.secureTextFields["password"].typeText("password123")
    app.buttons["Login"].tap()

    XCTAssertTrue(app.staticTexts["Welcome"].exists)
}

Android (Espresso)

kotlin

@Test
fun loginSuccess() {
    onView(withId(R.id.email)).perform(typeText("user@example.com"))
    onView(withId(R.id.password)).perform(typeText("password123"))
    onView(withId(R.id.loginButton)).perform(click())
    onView(withId(R.id.dashboard)).check(matches(isDisplayed()))
}

Best Practices

Test business logic first (unit tests)
Mock external dependencies
Test both success and failure paths
Automate critical user flows
Maintain >80% code coverage
Test on real devices periodically

Avoid

Testing implementation details
Hardcoded test data
Interdependent tests
Skipping error case testing
