Spring Boot - Testing Spring Boot Applications

Given this test snippet using TestRestTemplate:

var response = restTemplate.getForEntity("/api/greet", String.class);
System.out.println(response.getStatusCodeValue());
System.out.println(response.getBody());

If the endpoint /api/greet returns HTTP 200 and body "Hello!", what will be printed?

A200\nnull

B404\nNot Found

C500\nInternal Server Error

D200\nHello!

Step-by-Step Solution

Solution:

Step 1: Understand getForEntity behavior
It sends GET request and returns response with status and body.
Step 2: Match expected endpoint response
The endpoint returns 200 status and "Hello!" body, so these print exactly.
Final Answer:
200\nHello! -> Option D
Quick Check:
Status 200 and body "Hello!" printed [OK]

Quick Trick: Response status and body print as returned by endpoint [OK]

Common Mistakes:

Assuming 404 if endpoint not found in test
Expecting null body when response is valid
Confusing status code with body content
