We Keep Coding

Getting "Failed to load ApplicationContext" only on test environment

My app works ok when i run it. Now I'm coding some integration tests.
I managed to build a Test Container environment and it's working properly. But when I tried to test the login endpoint with Spring Security, it fails to load the application.
I was doing my requests on Postman, and this specific request was a POST with the x-www-urlencoded content, with the email and password in it. But the app got bigger and harder to test anything by hand.
I already successfuly tested the registration endpoint, thats why I think the problem started when I needed to use WebSecurityConfig class.
This is my SecurityConfiguration class:
#Configuration
#AllArgsConstructor
#EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
private final UserService userService;
private final BCryptPasswordEncoder bCryptPasswordEncoder;
#Override
protected void configure(HttpSecurity http) throws Exception {
CustomAuthenticationFilter customAuthenticationFilter = new CustomAuthenticationFilter(authenticationManagerBean());
customAuthenticationFilter.setFilterProcessesUrl("/api/v1/login");
http.csrf().disable();
http.sessionManagement().sessionCreationPolicy(STATELESS)
.and()
.authorizeRequests().antMatchers("/api/v1/login/**", "/api/v1/user/token/refresh/**").permitAll()
.and()
.authorizeRequests().antMatchers("/api/v1/registration/**").permitAll()
.and()
.authorizeRequests().antMatchers("/api/v1/user/**").hasAnyAuthority("ROLE_ADMIN", "ROLE_USER")
.and()
.addFilter(customAuthenticationFilter)
.addFilterBefore(new CustomAuthorizationFilter(), UsernamePasswordAuthenticationFilter.class);
}
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(daoAuthenticationProvider());
}
#Bean
public DaoAuthenticationProvider daoAuthenticationProvider() {
DaoAuthenticationProvider provider = new DaoAuthenticationProvider();
provider.setPasswordEncoder(bCryptPasswordEncoder);
provider.setUserDetailsService(userService);
return provider;
}
#Bean
#Override
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
}
This is my test class:
#IntegrationTest
#Slf4j
#ContextConfiguration(classes = {WebSecurityConfig.class})
class UserLoginIntegrationTest {
#Autowired
private WebApplicationContext context;
#Autowired
private UserRepository userRepository;
private MockMvc mockMvc;
#BeforeEach
public void setup() {
mockMvc = MockMvcBuilders
.webAppContextSetup(context)
.build();
}
#Test
void shouldSuccessWhenAttemptingToLoginWithValidData() throws Exception {
UserRegistrationRequest requestObject = userRegistrationRequest(1L);
userRepository.save(enabledUserFrom(requestObject));
assertThat(userRepository.findByEmail(requestObject.getEmail())).isPresent();
RequestBuilder request = urlEncodedLoginRequest(LOGIN_URL, new UserLoginRequest(requestObject.getEmail(), requestObject.getPassword()));
MvcResult result = this.mockMvc.perform(request).andExpect(status().is2xxSuccessful()).andReturn();
MvcResult result2 = mockMvc.perform(post(LOGIN_URL).with(httpBasic(requestObject.getEmail(),requestObject.getPassword()))).andExpect(status().is2xxSuccessful()).andReturn();
assertThat(result.getResponse().getContentAsString()).contains("access_token");
assertThat(result2.getResponse().getContentAsString()).contains("access_token");
}
The IntagrationTest annotation above stands for this interface below:
#Target(ElementType.TYPE)
#Retention(RetentionPolicy.RUNTIME)
#ExtendWith(PostgresTestContainer.class)
#RunWith(SpringRunner.class)
#WebMvcTest
#ActiveProfiles(profiles = "test")
#Transactional
public #interface IntegrationTest {
}

This UserService is used on the UserController as well on the WebSecurityConfig.
It would be awesome if there's a better way of doing this.
I know WebSecurityConfigurerAdapter is now deprecated, but didn't spent time changing it yet.
Thank you very much.

Try defining a mock of the UserService in your UserLoginIntegrationTest class.
#MockBean
UserService userService;
If you want to test real implementation, I believe you will need to start the whole application context.

Unable to test Spring Boot Rest Controller (stack trace attached)

I'm trying to write tests for my Rest controller. I followed this guide here: https://www.javachinna.com/spring-boot-rest-controller-junit-tests-mockito/ and tried to apply it to my own setup. The application works fine, I just need to know how to write the tests.
Here is the stack trace I am getting:

If anyone has any resources for learning how to do this with modern practices, I would appreciate any and all knowledge passed on.

You need to add a public default constructor (one without a parameters) in AuthController.
Then create a method with annotation #PostConstruct to initialize your AuthController with values that it needs to work properly.
I personally prefer dependency injection through setters because it's easier to create test in that way.
Here you have a nice example of how to do dependency injection with setters: https://www.amitph.com/spring-setter-injection-example/

Unit Testing Javalin Framework, Mocking Context doesn't work

I'm using Javalin 4 and Mockito 4, and I want to test a simple controller method.
I was reading a tutorial in here : https://javalin.io/tutorials/testing
here is my controller :
package mhndev.controller;
import io.javalin.http.Context;
public final class CakeController
{
private CakeController() {}
static String[] cakes = {"Cheese", "Chocolate", "Carrot", "Banana"};
public static void getOneCake(Context ctx) {
for(String cake: cakes) {
if(cake.equals(ctx.pathParam("cake"))) {
ctx.result(cake);
return;
}
}
ctx.result("cake was not found!");
}
}
And this is my very simple test:
package mhndev;
import io.javalin.http.Context;
import mhndev.controller.CakeController;
import org.junit.jupiter.api.Test;
import static org.mockito.Mockito.*;
public class CakeControllerTest {
private final Context ctx = mock(Context.class);
#Test
public void GET_apple_cakes() {
when(ctx.pathParam("cake")).thenReturn("Banana");
CakeController.getOneCake(ctx);
verify(ctx, times(1)).pathParam("Banana");
}
}
And I received this error upon running the test :
java.lang.NullPointerException: Parameter specified as non-null is null: method io.javalin.http.util.ContextUtil.pathParamOrThrow, parameter pathParams
at io.javalin.http.util.ContextUtil.pathParamOrThrow(ContextUtil.kt)

It's like Context.pathParam method is really getting called, using mockito and mocking the context object shouldn't create a new object and not calling the real method from real object? Why this happens and How should I test?

https://spring.io/guides/gs/consuming-rest/ Consuming a RESTful Web Service

I am trying to learn spring by doing it's quick guides, and when I was trying to follow this spring quick guide I have problems, even if I do everything as it's put there.
I have problems en the consuming Rest guide, but I thing there is a mistake in the http request link.
Here you can find the guide https://spring.io/guides/gs/consuming-rest/
In my com.example.consumingrest I have:
package com.example.consumingrest;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.boot.CommandLineRunner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;
#SpringBootApplication
public class ConsumingRestApplication {
private static final Logger log = LoggerFactory.getLogger(ConsumingRestApplication.class);
public static void main(String[] args) {
SpringApplication.run(ConsumingRestApplication.class, args);
}
#Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
return builder.build();
}
#Bean
public CommandLineRunner run(RestTemplate restTemplate) throws Exception {
return args -> {
Quote quote = restTemplate.getForObject(
"https://gturnquist-quoters.cfapps.io/api/random", Quote.class);
log.info(quote.toString());
};
}
}
the file Value.java
package com.example.consumingrest;
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
#JsonIgnoreProperties(ignoreUnknown = true)
public class Value {
private Long id;
private String quote;
public Value() {
}
public Long getId() {
return this.id;
}
public String getQuote() {
return this.quote;
}
public void setId(Long id) {
this.id = id;
}
public void setQuote(String quote) {
this.quote = quote;
}
#Override
public String toString() {
return "Value{" +
"id=" + id +
", quote='" + quote + '\'' +
'}';
}
}
and the qoute.java:
package com.example.consumingrest;
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
#JsonIgnoreProperties(ignoreUnknown = true)
public class Quote {
private String type;
private Value value;
public Quote() {
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public Value getValue() {
return value;
}
public void setValue(Value value) {
this.value = value;
}
#Override
public String toString() {
return "Quote{" +
"type='" + type + '\'' +

}
}

But I should get:

Your assumption is right. The request url is not found. When I tried navigating to the url mentioned, the browser itself throws a 404 not found error code. This is not an issue with your code.

java.lang.ExceptionInInitializerError when trying to mock

I'm running into this issue when trying to mock an object of the interface org.springframework.ui.Model. I'm using Mockito 3.5.15 w/Java 8 and JUnit Jupiter. I've tried using both #Mock and Mockito.mock(), globally and inside a method, but get the error regardless. Since initMocks() is deprecated, I am using Mockito.openMocks(). I know that the contents of testGetMenu() aren't causing the error, because I get it even when the method body is empty. The class being tested is a Spring MVC controller.

The use case you want to test is not what #InjectMocks in combination with #Mock is made for. You use this setup whenever you want to mock a collaborator of your class under test.
Let's say your AppController would inject (e.g. via constructor) a UserService to fetch data. For this scenario, you could then use #Mock for the UserService and mock the behavior of this service throughout your whole unit test for your AppController.
The Model is not a collaborator of your AppController, but rather injected by Spring to your method.
In your test scenario, mocking the Model does not make much sense. Rather use #WebMvcTest to start a sliced Spring Context and then use MockMvc to access your endpoint. You can then use verification methods of MockMvc to check the Model, the view name, the response code.
An example of this might look like the following:
#WebMvcTest(DashboardController.class)
class DashboardControllerTest {
#Autowired
private MockMvc mockMvc;
#MockBean
private DashboardService dashboardService;
#Test
public void shouldReturnViewWithPrefilledData() throws Exception {
when(dashboardService.getAnalyticsGraphData()).thenReturn(new Integer[]{13, 42});
this.mockMvc
.perform(get("/dashboard"))
.andExpect(status().isOk())
.andExpect(view().name("dashboard"))
.andExpect(model().attribute("user", "Duke"))
.andExpect(model().attribute("analyticsGraph", Matchers.arrayContaining(13, 42)))
.andExpect(model().attributeExists("quickNote"));
}
}
You can find more information in this MockMvc guide.
PS: #RunWith(MockitoRunner.class) is for JUnit 4, you can remove it if you use JUnit Jupiter.
