Spring WS - Unit Test Client

---

---

In this chapter, we will learn how to unit test a client created in the Spring WS - Writing Client for the web application server created in chapter Spring WS - Writing Server using Spring WS.

CountryServiceClientTest.java

package com.tutorialspoint;

import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.BeforeEach;
import org.junit.jupiter.api.Test;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;

import com.tutorialspoint.client.CountryServiceClient;

public class CountryServiceClientTest {
   CountryServiceClient client;
   
   @BeforeEach
   public void setUp() throws Exception {
      client = new CountryServiceClient();
      Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
      marshaller.setContextPath("com.tutorialspoint");
      client.setMarshaller(marshaller);
      client.setUnmarshaller(marshaller);
   }
   @Test
   public void test() {
      GetCountryResponse response = client.getCountryDetails("United States");
      Country expectedCountry = new Country();
      expectedCountry.setCapital("Washington");
      Country actualCountry = response.getCountry();
      Assertions.assertEquals(expectedCountry.getCapital(), actualCountry.getCapital());
   }
}
