How do you work with environment variables in REST Assured tests?

• A. By declaring them in the test class
• B. By fetching the variables using System.getenv()
• C. By using properties files only
• D. By hardcoding them in the test methods

Answer: (B)

The correct answer revolves around the method of obtaining environment variables in REST Assured tests. Fetching environment variables using `System.getenv()` is a standard approach in Java applications, including those using REST Assured. This method allows you to retrieve environment-specific values dynamically, which is essential for writing tests that can run across different environments (like development, staging, or production) without changing the code. By calling `System.getenv("VARIABLE_NAME")`, you access the value of the environment variable named `VARIABLE_NAME`, which enables better flexibility and adaptability in your test configurations. This practice promotes good development ethics by separating the codebase from configuration details, allowing for cleaner and more maintainable code. Hardcoding values into the test methods can lead to a brittle test suite that is difficult to manage and validate across different configurations. Using properties files requires additional overhead to read and manage these files, which might not always be necessary if the environment leverages system variables effectively. Therefore, utilizing `System.getenv()` is not only the correct method but also aligns with best practices for creating robust and adaptable test scenarios within REST Assured.
