Q2. Explain correlation and Parameterization
Ans. 
Correlation is used to handle dynamic values in scripts, while Parameterization is used to pass different values to the script.
• Correlation is used to extract dynamic values from server responses and replace them in subsequent requests.

• Parameterization is used to pass different sets of data to the script for testing different scenarios.

• Correlation is important for maintaining session integrity and ensuring accurate test...read more
