Springboot test fails

[rustic grail]

I'm following this course https://www.youtube.com/watch?v=Geq60OVyBPg to integrate tests into my already pretty big project. I'm getting errors all over the place, would you recommend me the best approach to integrating tests into a big project?

While you are waiting for getting help, here are some tips to improve your experience:

Code is much easier to read if posted with syntax highlighting and proper formatting.

If nobody is calling back, that usually means that your question was not well asked and hence nobody feels confident enough answering. Try to use your time to elaborate, provide details, context, more code, examples and maybe some screenshots. With enough info, someone knows the answer for sure.

Don't forget to close your thread using the command </help-thread close:1027500463647621170> when your question has been answered, thanks.

this is extremely overwhelming, I can't manage to setup a decent test suite for any of my layers

I would literally pay for someone to link me an optimal guide on testing spring boot rest apis because this feels like black magic

I've tried building a functioning test suite for 3 days now I'm desperate

we can't help you if you don't tell us what the problem is

I've wrote a proper stack overflow question

so It's well formatted and easy to read

sorry for not providing it instantly

@rustic grail can you provide the entire stack trace? Usually bean loading errors sort of show what dependency path caused it to be triggered

[grand hollow]

I uploaded your attachments as gist. That way, they are easier to read for everyone, especially mobile users 👍

[rustic grail]

the requestFilter I guess (?)

@rustic grail might be because you've built a lot things till now, so obviously makes sense testing will cause lot of things to break

I am not sure if you are starting with unit testing first

You need to mock dependencies your classes are using so you won't interrupt them or cause real db connection to be established because that will eat a lot of time to execute each test

You need to mock and constructor-inject dependencies into your test classes

The error you shared above looks like a Spring MVC integration test error

[rustic grail]

I see

Yeah It was a misplaced bean class

I thought that one was an unit test honestly

But apparently isnt

I will delve into this problem

Can you link me any valuable resource to learn testing the proper way???

@hallow sun

Thanks for helping out

[red vault]

@rustic grail have you tried simply disabling the test profile

it seems the video you're using doesn't have that (or at least, the code they shared doesn't)

the root cause is a securityConfig bean btw, which should probably not have been loaded by the DataJpaTest annotation

[red vault]

mmh the sample code still works with the annotation, maybe it's good to compare it

Hello!

What classes or modules you want to test?

and unit test or integration test

Or both?

[rustic grail]

My plan was to unit test the persistence and service layer while making integration tests of the controller layer (as I'd have no idea how to unit test them)

Basically every relevant class

[hallow sun]

Sure @rustic grail I found a playlist

It can help you

here it is:

https://www.youtube.com/watch?v=lPHjo3EWeGA&list=PLGJny_f99PBLcK-rrOoU1tM3GyRLkFXSg

More imporatantly you will also find Stubbing which is quite indeed very useful for mimicking the behavior of your dependent classes

[rustic grail]

Thank you! Really appreciate it

It seems very well done

[hallow sun]

I would say take a look at TDD also

That is the fundamental of producing well-tested and clean code

[rustic grail]

Will do

[hallow sun]

https://www.youtube.com/watch?v=GvAzrC6-spQ

You can find a pretty much content about TDD (all talks, code walkthroughs)

on youtube

[rustic grail]

Will check this out (added everything in a playlist)

[hallow sun]

if you want more help, come in my DM, I will

[rustic grail]

I will leave this thread open while learning

Maybe will post some updates

hey, so for lack of time & will I ended up making half coverage. I solved the HandlerExceptionResolver error getting a good service/repository coverage with @DataJpaTest
but when moving on to integration testing the controller it complains giving me all those errors...

this is now the erro I'm getting: Error creating bean with name 'applicationLoggingAspect' defined in file [...] Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'applicationService' defined in file

This is how I've set up my testing suite:

@WebMvcTest(UserController.class)
@ActiveProfiles("test")
public class UserControllerTest {
    @MockBean
    private UserService userService;
    @Autowired
    private MockMvc mockMvc;
    @MockBean
    private RoleService roleService;

    @Test
    void auth() throws Exception {

        UserDto dto= createBasicDto();

        when(userService.getUserDtoByKey(eq(dto.getKey()))).thenReturn(dto);
        mockMvc.perform(get("/users/auth/")
                        .header("key",dto.getKey()))
                .andExpect(status().isAccepted());
    }
}

applicationLoggingAspect is an aspect class that just takes up a service and its dto. I use it to log stuff inside my api...

@Aspect
@Component
@Slf4j
public class ApplicationLoggingAspect extends BaseLoggingAspect<ApplicationService, ApplicationDto> {

    public ApplicationLoggingAspect(ApplicationService service) {
        super(service);
    }

    @Autowired
    LogService logService;
[...]
}```

Detected code, here are some useful tools:

Formatted code

@WebMvcTest(UserController.class ) @ActiveProfiles("test") public class UserControllerTest {
  @MockBean
  private UserService userService;
  @Autowired
  private MockMvc mockMvc;
  @MockBean
  private RoleService roleService;
  @Test
  void auth() throws Exception {
    UserDto dto = createBasicDto();
    when(userService.getUserDtoByKey(eq(dto.getKey()))).thenReturn(dto);
    mockMvc.perform(get("/users/auth/").header("key", dto.getKey())).andExpect(status().isAccepted());
  }
}

it was an dependency injection problem, I solved! :)) really thanks to @hallow sun
