Absolutely! You can absolutely use Selenium to launch Microsoft Edge with mobile device emulation enabled for your automated mobile testing needs. Let me break down exactly how to pull this off, with practical code examples and key tips.

Prerequisites First #

Before diving into code, make sure you have these bases covered:

• The latest version of Microsoft Edge installed on your machine
• A matching version of EdgeDriver (critical—EdgeDriver must align with your Edge browser version to avoid compatibility bugs)
• Selenium bindings installed for your preferred programming language (I’ll use Python here since it’s widely used for test automation)

Basic Implementation (Predefined Device) #

Here’s a working example that emulates an iPhone 14—one of Edge’s predefined mobile device profiles:

from selenium import webdriver
from selenium.webdriver.edge.options import Options

# Configure Edge options for mobile emulation
edge_options = Options()
mobile_emulation = {
    "deviceName": "iPhone 14"
}
edge_options.add_experimental_option("mobileEmulation", mobile_emulation)

# Launch Edge with the emulation settings
driver = webdriver.Edge(options=edge_options)

# Navigate to your target mobile site and run tests
driver.get("https://m.your-test-domain.com")

# Insert your test logic here (e.g., clicking elements, filling forms)

# Clean up: quit the driver when tests are done
driver.quit()

Customize Your Emulated Device #

If none of Edge’s predefined devices fit your needs, you can define custom parameters like screen dimensions, pixel ratio, and user agent:

mobile_emulation = {
    "deviceMetrics": { "width": 390, "height": 844, "pixelRatio": 3.0 },
    "userAgent": "Mozilla/5.0 (iPhone; CPU iPhone OS 16_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/16.0 Mobile/15E148 Safari/604.1"
}
edge_options.add_experimental_option("mobileEmulation", mobile_emulation)

Key Tips for Smooth Testing #

• Keep Edge and EdgeDriver in sync: Every time you update Edge, download the corresponding EdgeDriver version immediately—mismatches cause most common errors here.
• Touch gestures: For actions like swiping or pinching, use Selenium’s ActionChains (or the newer Actions API) to simulate touch interactions accurately.
• Cross-language support: If you use Java, C#, or another language, the core logic stays the same—you’ll just configure the mobile emulation capability in the Edge driver’s options instead of Python’s Options class.
