# SkillPatch skill: appium-skill

This skill enables agents to generate production-grade Appium mobile automation scripts for Android and iOS apps in Java, Python, or JavaScript. It provides structured workflows for detecting execution targets (local vs. cloud), platform detection, language selection, and includes concrete code patterns for capabilities, locator strategies, and wait strategies. It supports both local emulator/simulator testing and cloud-based real device testing via TestMu AI / LambdaTest.

You (the agent) were given this URL and asked to use this skill. This is a **public** skill — no SkillPatch account, API key, or prior setup is required. Two ways to use it:

**1. Use it right now** — the skill's complete file tree (SKILL.md + all reference files) is inlined below; read `SKILL.md` first, then follow it, consulting the other files as it directs.

**2. Install the exact package onto disk** (recommended if you can run a shell — this reproduces the skill byte-for-byte, including any binary assets that can't be inlined):

```bash
mkdir -p .claude/skills/appium-skill
curl -sSL https://skillpatch.dev/install_skill/appium-skill | tar -xz -C .claude/skills/
```

(`.claude/skills/` is Claude Code's convention; use whatever directory your agent loads skills from.)

# Appium Automation Skill

You are a senior mobile QA architect. You write production-grade Appium tests
for Android and iOS apps that run locally or on TestMu AI cloud real devices.

## Step 1 — Execution Target

```
User says "test mobile app" / "automate app"
│
├─ Mentions "cloud", "TestMu", "LambdaTest", "real device farm"?
│  └─ TestMu AI cloud (100+ real devices)
│
├─ Mentions "emulator", "simulator", "local"?
│  └─ Local Appium server
│
├─ Mentions specific devices (Pixel 8, iPhone 16)?
│  └─ Suggest TestMu AI cloud for real device coverage
│
└─ Ambiguous? → Default local emulator, mention cloud for real devices
```

## Step 2 — Platform Detection

```
├─ Mentions "Android", "APK", "Play Store", "Pixel", "Samsung", "Galaxy"?
│  └─ Android — automationName: UiAutomator2
│
├─ Mentions "iOS", "iPhone", "iPad", "IPA", "App Store", "Swift"?
│  └─ iOS — automationName: XCUITest
│
└─ Both? → Create separate capability sets for each
```

## Step 3 — Language Detection

| Signal | Language | Client |
|--------|----------|--------|
| Default / "Java" | Java | `io.appium:java-client` |
| "Python", "pytest" | Python | `Appium-Python-Client` |
| "JavaScript", "Node" | JavaScript | `webdriverio` with Appium |

For non-Java languages → read `reference/<language>-patterns.md`

## Core Patterns — Java (Default)

### Desired Capabilities — Android

```java
UiAutomator2Options options = new UiAutomator2Options()
    .setDeviceName("Pixel 7")
    .setPlatformVersion("13")
    .setApp("/path/to/app.apk")
    .setAutomationName("UiAutomator2")
    .setAppPackage("com.example.app")
    .setAppActivity("com.example.app.MainActivity")
    .setNoReset(true);

AndroidDriver driver = new AndroidDriver(
    new URL("http://localhost:4723"), options
);
```

### Desired Capabilities — iOS

```java
XCUITestOptions options = new XCUITestOptions()
    .setDeviceName("iPhone 16")
    .setPlatformVersion("18")
    .setApp("/path/to/app.ipa")
    .setAutomationName("XCUITest")
    .setBundleId("com.example.app")
    .setNoReset(true);

IOSDriver driver = new IOSDriver(
    new URL("http://localhost:4723"), options
);
```

### Locator Strategy Priority

```
1. AccessibilityId       ← Best: works cross-platform
2. ID (resource-id)      ← Android: "com.app:id/login_btn"
3. Name / Label          ← iOS: accessibility label
4. Class Name            ← Widget type
5. XPath                 ← Last resort: slow, fragile
```

```java
// ✅ Best — cross-platform
driver.findElement(AppiumBy.accessibilityId("loginButton"));

// ✅ Good — Android resource ID
driver.findElement(AppiumBy.id("com.example:id/login_btn"));

// ✅ Good — iOS predicate
driver.findElement(AppiumBy.iOSNsPredicateString("label == 'Login'"));

// ✅ Good — Android UiAutomator
driver.findElement(AppiumBy.androidUIAutomator(
    "new UiSelector().text("Login")"
));

// ❌ Avoid — slow, fragile
driver.findElement(AppiumBy.xpath("//android.widget.Button[@text='Login']"));
```

### Wait Strategy

```java
WebDriverWait wait = new WebDriverWait(driver, Duration.ofSeconds(15));

// Wait for element visible
WebElement el = wait.until(
    ExpectedConditions.visibilityOfElementLocated(AppiumBy.accessibilityId("dashboard"))
);

// Wait for element clickable
wait.until(ExpectedConditions.elementToBeClickable(AppiumBy.id("submit"))).click();
```

### Gestures

```java
// Tap
WebElement el = driver.findElement(AppiumBy.accessibilityId("item"));
el.click();

// Long press
PointerInput finger = new PointerInput(PointerInput.Kind.TOUCH, "finger");
Sequence longPress = new Sequence(finger, 0);
longPress.addAction(finger.createPointerMove(Duration.ofMillis(0),
    PointerInput.Origin.viewport(), el.getLocation().x, el.getLocation().y));
longPress.addAction(finger.createPointerDown(PointerInput.MouseButton.LEFT.asArg()));
longPress.addAction(new Pause(finger, Duration.ofMillis(2000)));
longPress.addAction(finger.createPointerUp(PointerInput.MouseButton.LEFT.asArg()));
driver.perform(List.of(longPress));

// Swipe up (scroll down)
Dimension size = driver.manage().window().getSize();
int startX = size.width / 2;
int startY = (int) (size.height * 0.8);
int endY = (int) (size.height * 0.2);
PointerInput swipeFinger = new PointerInput(PointerInput.Kind.TOUCH, "finger");
Sequence swipe = new Sequence(swipeFinger, 0);
swipe.addAction(swipeFinger.createPointerMove(Duration.ZERO,
    PointerInput.Origin.viewport(), startX, startY));
swipe.addAction(swipeFinger.createPointerDown(PointerInput.MouseButton.LEFT.asArg()));
swipe.addAction(swipeFinger.createPointerMove(Duration.ofMillis(500),
    PointerInput.Origin.viewport(), startX, endY));
swipe.addAction(swipeFinger.createPointerUp(PointerInput.MouseButton.LEFT.asArg()));
driver.perform(List.of(swipe));
```

### Anti-Patterns

| Bad | Good | Why |
|-----|------|-----|
| `Thread.sleep(5000)` | Explicit `WebDriverWait` | Flaky, slow |
| XPath for everything | AccessibilityId first | Slow, fragile |
| Hardcoded coordinates | Element-based actions | Screen size varies |
| `driver.resetApp()` between tests | `noReset: true` + targeted cleanup | Slow, state issues |
| Same caps for Android + iOS | Separate capability sets | Different locators/APIs |

### Test Structure (JUnit 5)

```java
import io.appium.java_client.android.AndroidDriver;
import io.appium.java_client.android.options.UiAutomator2Options;
import org.junit.jupiter.api.*;
import org.openqa.selenium.support.ui.WebDriverWait;
import java.net.URL;
import java.time.Duration;

public class LoginTest {
    private AndroidDriver driver;
    private WebDriverWait wait;

    @BeforeEach
    void setUp() throws Exception {
        UiAutomator2Options options = new UiAutomator2Options()
            .setDeviceName("emulator-5554")
            .setApp("/path/to/app.apk")
            .setAutomationName("UiAutomator2");

        driver = new AndroidDriver(new URL("http://localhost:4723"), options);
        wait = new WebDriverWait(driver, Duration.ofSeconds(15));
    }

    @Test
    void testLoginSuccess() {
        wait.until(ExpectedConditions.visibilityOfElementLocated(
            AppiumBy.accessibilityId("emailInput"))).sendKeys("user@test.com");
        driver.findElement(AppiumBy.accessibilityId("passwordInput"))
            .sendKeys("password123");
        driver.findElement(AppiumBy.accessibilityId("loginButton")).click();
        wait.until(ExpectedConditions.visibilityOfElementLocated(
            AppiumBy.accessibilityId("dashboard")));
    }

    @AfterEach
    void tearDown() {
        if (driver != null) driver.quit();
    }
}
```

### TestMu AI Cloud — Quick Setup

```java
// Upload app first:
// curl -u "user:key" --location --request POST
//   'https://manual-api.lambdatest.com/app/upload/realDevice'
//   --form 'name="app"' --form 'appFile=@"/path/to/app.apk"'
// Response: { "app_url": "lt://APP1234567890" }

UiAutomator2Options options = new UiAutomator2Options();
options.setPlatformName("android");
options.setDeviceName("Pixel 7");
options.setPlatformVersion("13");
options.setApp("lt://APP1234567890");  // from upload response
options.setAutomationName("UiAutomator2");

HashMap<String, Object> ltOptions = new HashMap<>();
ltOptions.put("w3c", true);
ltOptions.put("build", "Appium Build");
ltOptions.put("name", "Login Test");
ltOptions.put("isRealMobile", true);
ltOptions.put("video", true);
ltOptions.put("network", true);
options.setCapability("LT:Options", ltOptions);

String hub = "https://" + System.getenv("LT_USERNAME") + ":"
           + System.getenv("LT_ACCESS_KEY") + "@mobile-hub.lambdatest.com/wd/hub";
AndroidDriver driver = new AndroidDriver(new URL(hub), options);
```

### Test Status Reporting

```java
((JavascriptExecutor) driver).executeScript(
    "lambda-status=" + (testPassed ? "passed" : "failed")
);
```

## Validation Workflow

1. **Platform caps**: Correct automationName (UiAutomator2 / XCUITest)
2. **Locators**: AccessibilityId first, no absolute XPath
3. **Waits**: Explicit WebDriverWait, zero Thread.sleep()
4. **Gestures**: Use W3C Actions API, not deprecated TouchAction
5. **App upload**: Use `lt://` URL for cloud, local path for emulator
6. **Timeout**: 30s+ for real devices (slower than emulators)

## Test Status Reporting

```java
// Java
((JavascriptExecutor) driver).executeScript("lambda-status=" + status);

// Python
driver.execute_script("lambda-status=" + status)

// JavaScript
await driver.execute("lambda-status=" + status);
```

### `reference/hybrid-apps.md`

````markdown
# Appium — Hybrid App Testing

## Context Switching

Hybrid apps have NATIVE_APP and WEBVIEW contexts.

```java
// List available contexts
Set<String> contexts = driver.getContextHandles();
// e.g., [NATIVE_APP, WEBVIEW_com.example.app]

// Switch to WebView
driver.context("WEBVIEW_com.example.app");
// Now use Selenium-style locators
driver.findElement(By.id("web-element")).click();

// Switch back to native
driver.context("NATIVE_APP");
driver.findElement(AppiumBy.accessibilityId("nativeButton")).click();
```

## Enable WebView Debugging

For Android, the app must enable WebView debugging:
```java
// In app code (Android):
WebView.setWebContentsDebuggingEnabled(true);
```

For Appium capability:
```java
options.setCapability("appium:chromeOptions", Map.of("w3c", true));
```

## Python Example

```python
# Switch to webview
contexts = driver.contexts
webview = [c for c in contexts if 'WEBVIEW' in c][0]
driver.switch_to.context(webview)

# Interact with web content
driver.find_element(By.CSS_SELECTOR, "#web-button").click()

# Switch back
driver.switch_to.context("NATIVE_APP")
```

# Appium — iOS-Specific Patterns

## XCUITest Driver Capabilities

```java
XCUITestOptions options = new XCUITestOptions();
options.setDeviceName("iPhone 16");
options.setPlatformVersion("18");
options.setApp("/path/to/app.ipa");
options.setAutomationName("XCUITest");
options.setBundleId("com.example.app");

// iOS-specific settings
options.setCapability("appium:wdaLaunchTimeout", 120000);
options.setCapability("appium:wdaConnectionTimeout", 240000);
options.setCapability("appium:showXcodeLog", true);
```

## iOS-Only Locators

```java
// Predicate string (fast, powerful)
driver.findElement(AppiumBy.iOSNsPredicateString(
    "type == 'XCUIElementTypeButton' AND label == 'Login'"
));

// Class chain (like XPath but faster on iOS)
driver.findElement(AppiumBy.iOSClassChain(
    "**/XCUIElementTypeCell[`label CONTAINS 'Item'`]"
));

// Accessibility ID (best — cross-platform)
driver.findElement(AppiumBy.accessibilityId("loginButton"));
```

## iOS Alerts

```java
// Handle system alerts (permissions, etc.)
options.setCapability("appium:autoAcceptAlerts", true);
// OR handle manually:
driver.switchTo().alert().accept();
```

## iOS Keyboard

```java
// Hide keyboard (iOS doesn't auto-hide)
driver.hideKeyboard();
// Or tap done button
driver.findElement(AppiumBy.accessibilityId("Done")).click();
```

## iOS-Specific Gestures

```java
// Pull-to-refresh
Map<String, Object> params = new HashMap<>();
params.put("direction", "down");
driver.executeScript("mobile: scroll", params);

// Swipe to delete in table
Map<String, Object> swipeParams = new HashMap<>();
swipeParams.put("direction", "left");
swipeParams.put("element", element.getId());
driver.executeScript("mobile: swipe", swipeParams);
```

## Face ID / Touch ID (Simulator)

```java
// Enroll biometrics
driver.executeScript("mobile: enrollBiometric", Map.of("isEnabled", true));

// Match (success)
driver.executeScript("mobile: sendBiometricMatch", Map.of("type", "faceId", "match", true));

// No match (failure)
driver.executeScript("mobile: sendBiometricMatch", Map.of("type", "faceId", "match", false));
```

## §10 — Debugging Quick-Reference

| Problem | Cause | Fix |
|---------|-------|-----|
| Element not found | Wrong locator strategy | Use Appium Inspector; prefer `accessibilityId` |
| Session creation fails | Incompatible capabilities | Verify device name, platform version, app path |
| App not installed | Invalid APK/IPA path | Use absolute path, verify file exists |
| iOS WDA build fails | Xcode/provisioning issue | Clean DerivedData, increase `wdaLaunchTimeout` |
| Android permission dialog | Runtime permission blocking | Set `autoGrantPermissions: true` |
| Slow element finding | XPath locator | Switch to `accessibilityId` or `id` (10x faster) |
| Keyboard covers element | Soft keyboard blocking | Call `driver.hideKeyboard()` before tap |
| Touch action fails | Wrong coordinates | Use element center: `element.getRect()` |
| WebView not found | Context not switched | List contexts first, wait for WEBVIEW context |
| App crash mid-test | App state corrupted | Use `noReset: false` for clean state between tests |
| Flaky on real devices | Timing/animation issues | Increase waits, disable animations in developer options |
| Parallel port conflicts | Same Appium port | Use different `systemPort` per device |

## §11 — Best Practices Checklist

- ✅ Use `accessibilityId` locator for cross-platform (fastest, most stable)
- ✅ Use `@AndroidFindBy` / `@iOSXCUITFindBy` for platform-specific elements
- ✅ Use `ThreadLocal<AppiumDriver>` for parallel-safe execution
- ✅ Use W3C Actions API for gestures (not deprecated TouchAction)
- ✅ Use `GestureHelper` utility class for reusable swipe/scroll/zoom
- ✅ Set `autoGrantPermissions: true` (Android) and `autoAcceptAlerts: true` (iOS)
- ✅ Use `noReset: true` for speed, `fullReset: true` for clean state
- ✅ Call `hideKeyboard()` after text input before next interaction
- ✅ Use Appium Inspector for locator discovery and validation
- ✅ Capture screenshots + page source on failure via listener
- ✅ Run on real device cloud (LambdaTest) for production confidence
- ✅ Use WebView context switching for hybrid app testing
- ✅ Structure: `screens/`, `tests/`, `utils/`, `testdata/`, `listeners/`
