What should the developer do to meet these requirements?
Set up a mock integration request in API Gateway. Configure the method’s integration request and integration response to associate a response with a given status code.
Set up the request validators in the API’s OpenAPI definition file. Import the OpenAPI definitions into API Gateway to test the API.
Set up a gateway response for the API in API Gateway. Configure response headers with hardcoded HTTP status codes and responses.
Set up a request parameter-based Lambda authorizer to control access to the API. Configure the Lambda function with the necessary mapping template.
Explanations:
Setting up a mock integration allows the developer to create predefined responses for API requests without needing a backend service. This is ideal for testing and enables other teams to interact with the API immediately using mock data. It also allows configuring specific response codes, making it flexible for various testing scenarios.
While setting up request validators in an OpenAPI definition can be useful for validating requests, it does not directly help in generating API responses for testing. Importing the OpenAPI definitions into API Gateway does not provide immediate test responses; it is focused on defining the structure and validation of the API.
Configuring a gateway response with hardcoded HTTP status codes and responses does not facilitate immediate testing for teams. Gateway responses are more for handling errors and customizing responses for specific status codes rather than generating testable API responses during development.
A request parameter-based Lambda authorizer is used for controlling access to the API rather than generating responses. While it can secure the API, it does not directly assist in creating mock responses for testing purposes, which is the primary requirement in this scenario.
I compute that the answer is:
Set up a mock integration request in API Gateway. Configure the method’s integration request and integration response to associate a response with a given status code.
