How do you implement handling of responses to incoming requests in your system?

The processing of responses to incoming requests in the system is usually implemented through the following steps:

1. Receiving the request — the server or test system accepts the incoming request.
2. Parsing and validation — the correctness and completeness of the request data are checked.
3. Executing processing logic — based on the request, the necessary functionality or service is invoked.
4. Forming the response — a response with the required data or status is created.
5. Sending the response — the response is returned to the client or calling system.

In QA Automation, to verify responses, the following are usually implemented:

• Automated tests that send requests and check the correctness of responses (statuses, body, headers).
• Logging and analyzing responses to identify errors.
• Using tools (e.g., Postman, REST-assured) for convenient work with requests and responses.

An example in Java using REST-assured to verify the response:

given()
  .when()
    .get("https://api.example.com/data")
  .then()
    .statusCode(200)
    .body("name", equalTo("John"));

Thus, response processing is a combination of correct server-side logic and validation of correctness during testing.
