Integration Testing

Purpose

Integration testing verifies that the components of the API interact correctly, as expected in end-to-end workflows.

Test Approach

• Use mock requests and mock data where appropriate.
• Confirm that endpoints return correct status codes and response structures.
• Verify that POST requests correctly process input data.

Example Integration Test Cases

Test Case	Description	Input	Expected Output
GET /test	Verify endpoint returns correct JSON	N/A	{ "name": "Test1", "status": "test" }
POST /test/:id with info	Ensure POST data is processed	{ "info": "hello" } and id=123	{ "name": "Test message with info: hello and ID: 123" }
POST /test/:id without info	Validate handling of missing data	{} and id=123	Status code 418 with { "message": "No info!" }

Running Integration Tests

Currently, the unit tests also serve as a basic integration check.

npm test

Notes

• All tests are automated.
• No manual entry or interpretation is required.
