We can use an embedded web server to test our web application. We can achieve that by using
@SpringBootTest(webEnvironment = RANDOM_PORT)
and injecting WebTestClient.
WebTestClient is similar to WebClient but after exchange() call further chined methods are used to verify responses.
Example

Example web application
package com.logicbig.example;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
public class MyMvcController {
@Autowired
private HelloService helloService;
@GetMapping(value = "/")
@ResponseBody
public String sayHi(String name) {
return helloService.getMessage(name);
}
}
package com.logicbig.example;
import org.springframework.stereotype.Service;
@Service
public class HelloService {
public String getMessage(String name) {
return String.format("Hi there, %s.", name);
}
}
package com.logicbig.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class WebAppMain {
public static void main(String[] args) {
SpringApplication.run(WebAppMain.class, args);
}
}
JUnit test with embedded server
package com.logicbig.example;
import org.junit.Test;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;

import org.springframework.test.web.reactive.server.WebTestClient;
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class MyWebAppTest {
@Autowired
private WebTestClient webTestClient;
@Test
public void testSayHi() {
webTestClient.get()
.uri(uriBuilder -> uriBuilder.path("/")
.queryParam("name", "Joe")
.build())
.exchange()
.expectStatus().isOk()
.expectBody(String.class).isEqualTo("Hi there, Joe.");
