When Restassured can be useful

Ideal Scenarios

• Testing backend services and microservices independently of the UI.
• Validating APIs as part of a CI/CD pipeline for fast regression feedback.
• Verifying data contracts between services in a Java-based tech stack.
• Automating large numbers of positive and negative test cases across many endpoints.

When It May Not Be the Best Fit

For teams without Java expertise, or for very quick, one-off exploratory checks, a GUI tool like Postman may be more efficient.
