Real Device Testing with Appium

 📱 Real Device Testing with Appium

Appium is an open-source tool used for automating mobile applications (iOS and Android). Testing on real devices is essential because it gives more accurate results compared to emulators or simulators.


✅ Why Test on Real Devices?

More accurate performance and behavior


Better handling of hardware features (camera, GPS, etc.)


Real user conditions (network, battery, memory)


Identifies bugs missed in emulators


🧰 Prerequisites

🔧 For Android:

Android device with Developer Mode enabled


USB Debugging turned on


Install ADB (Android Debug Bridge)


🍎 For iOS:

macOS system with Xcode


Physical iOS device with a valid Apple developer account


USB connection and WebDriverAgent installed


Common Requirements:

Install Appium Server


Install required drivers (UIAutomator2 for Android, XCUITest for iOS)


Install Java, Node.js, and Appium Client libraries (Java, Python, JS, etc.)


Use tools like Appium Desktop or Appium Inspector (optional, for debugging)


🚀 Basic Steps for Real Device Testing

1. Connect the Device

For Android: Use adb devices to verify the device is detected.


For iOS: Use Xcode > Devices and Simulators to ensure the device is visible.


2. Set Desired Capabilities

These are settings that tell Appium how to connect and interact with your app.


🧪 Example for Android:

python

Copy

Edit

from appium import webdriver


desired_caps = {

    "platformName": "Android",

    "platformVersion": "13.0",

    "deviceName": "Android Device",

    "automationName": "UiAutomator2",

    "appPackage": "com.example.app",

    "appActivity": ".MainActivity",

    "noReset": True

}


driver = webdriver.Remote("http://localhost:4723/wd/hub", desired_caps)

🍏 Example for iOS:

python

Copy

Edit

desired_caps = {

    "platformName": "iOS",

    "platformVersion": "16.0",

    "deviceName": "iPhone 14",

    "automationName": "XCUITest",

    "udid": "<your-device-udid>",

    "xcodeOrgId": "<your-org-id>",

    "xcodeSigningId": "iPhone Developer",

    "bundleId": "com.example.app"

}

3. Write and Run Your Test Script

Example (Python):


python

Copy

Edit

driver.find_element("id", "login_button").click()

Use locators like:


id


xpath


accessibility_id


class name


4. Execute the Script

Run your script using a test framework (like Pytest, JUnit, or Mocha) and observe the app behavior on the real device.


5. Analyze Results

Use Appium logs


Screenshots or video recording (optional)


Validate success/failure of test cases


🛡️ Tips & Best Practices

Always clean up after tests (driver.quit())


Use real user scenarios for more reliable results


Test on multiple real devices (different OS versions, brands)


Monitor logs for crashes, memory leaks, etc.


📌 Summary

Step What You Do

Connect real device USB + enable debugging (ADB/iOS setup)

Set capabilities Tell Appium how to run the test

Start Appium server Use Appium Desktop or run via command line

Write & run test script Automate actions like login, click, swipe

Analyze results Use logs, screenshots, and test output

Handling Frames and Iframes Using Playwright

Handling Frames and Iframes Using Playwright When automating modern web applications, you’ll often come across frames or iframes—HTML elements used to embed another HTML document within the current page. If you're using Playwright for browser automation, knowing how to handle frames properly is crucial for interacting with elements inside them. In this blog, we’ll walk through how to identify, access, and interact with frames and iframes using Playwright with code examples in JavaScript and Python. 🧾 What Are Frames and Iframes? <frame>: Rarely used now; part of the outdated <frameset> HTML structure. <iframe> (inline frame): Embeds another HTML page inside the current one. Common for third-party content like ads, maps, or payment gateways. 🎯 Why Frames Matter in Automation Elements inside an iframe are not part of the main DOM, so trying to interact with them directly will result in errors unless you switch the context to the frame. 🔍 Locating an Iframe in Pla...
