This tutorial shows a basic example of JUnit 5 Test Method.
Tutorial isn't using @SpringBootTest which means that @Autowired isn't work which is why we use new MyController().
This approach is useful when we don't need Spring Boot Context so that tests could run faster.

Create Project: springboot_junit (add Spring Boot Starters from the table)
Create Package: controllers (inside main package)
– Create Class: MyController.java (inside controllers package)
Create Test Class: MyControllerTest.java
MyController.java
package com.ivoronline.springboot_junit.controllers;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class MyController {
@ResponseBody
@RequestMapping("/Hello")
public String hello() {
return "Hello from Controller";
}
}
