⚙️ Centralized Configuration in RestAssured

📘 Introduction​

Centralized configuration is a key aspect of building a scalable and maintainable API automation framework. By externalizing settings like base URLs, authentication tokens, and environment-specific parameters, you can easily switch between environments without modifying your test code.

🎯 Why Centralize Configuration?​

  • Environment independence
  • Reusability
  • Maintainability
  • Security

🛠️ Using Properties Files​

base.uri=https://api.example.com
auth.token=token
RestAssured.baseURI = ConfigLoader.getProperty("base.uri");

📦 Using Constants​

public class EnvironmentConfig {
    public static final String BASE_URI = "https://api.example.com";
}

🔐 Using Environment Variables​

String baseUri = System.getenv("BASE_URI");

🌍 Multiple Environments​

mvn test -Denv=prod

✅ Best Practices​

  1. Externalize sensitive data
  2. Validate configs
  3. Use defaults wisely
  4. Document keys

🏁 Conclusion​

Centralized configuration improves flexibility, maintainability, and security of your API automation framework.
