Appium Parameterization Using Property File – TestNG (Part 8)

By Bhau Automation • Appium Automation Framework

🎯 What You Will Learn

• What is parameterization in TestNG
• How to read data from property file
• How Appium uses config files
• Passing values dynamically
• Creating scalable automation framework

📌 What is Parameterization?

Parameterization allows you to pass external input data into your automation scripts instead of hardcoding values. It helps in creating flexible, reusable, and scalable automation frameworks.

📁 Why Use Property File?

• Centralized configuration management
• Easy environment switching
• No hardcoded values
• Improves framework maintenance

📄 Sample config.properties File

platformName=Android
deviceName=Android Emulator
automationName=UiAutomator2
appPackage=com.saucelabs.mydemoapp
appActivity=com.saucelabs.mydemoapp.MainActivity

📘 Reading Property File in Java

Properties prop = new Properties();
FileInputStream fis = new FileInputStream("config.properties");
prop.load(fis);

String platform = prop.getProperty("platformName");
String device = prop.getProperty("deviceName");

🚀 Using Property Values in Appium

DesiredCapabilities caps = new DesiredCapabilities();
caps.setCapability("platformName", platform);
caps.setCapability("deviceName", device);
caps.setCapability("automationName", prop.getProperty("automationName"));
caps.setCapability("appPackage", prop.getProperty("appPackage"));
caps.setCapability("appActivity", prop.getProperty("appActivity"));

🧠 Benefits of Parameterization

• Reusable automation scripts
• Environment-independent execution
• Easy CI/CD integration
• Professional framework design
