@JsonTest does not load ApplicaitonContext correctly.

[hantsy]

I am trying to use@JsonTest to the @JsonComponent, but it seems there are some ApplicationContext loading problem existed.

The sample is hosted on my github, there is a 1.4-upgrade branch to taste Spring Boot 1.4.0M2.

https://github.com/hantsy/angularjs-springmvc-sample-boot/.

The test codes:

LocalDateTimeJsonComponentTest

If I used @JsonTest instead of @SpringBootTest, it will report the ApplicationSecurity constructor injection failure. The following is the logging details.

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.hantsylabs.restexample.springmvc.Application$ApplicationSecurity': Unsatisfied dependency expressed through constructor parameter 0: No qualifying bean of type [com.hantsylabs.restexample.springmvc.repository.UserRepository] found for dependency [com.hantsylabs.restexample.springmvc.repository.UserRepository]: expected at least 1 bean which qualifies as autowire candidate for this dependency.

[snicoll]

@JsonTest is not a replacement for @SpringBootTest; it is a way to easily test json serialization. Your application class is expecting a bunch of beans to be present (for instance JPA to be present with this UserRepository). They won't. You should move all that code to separate @Configuration classes.

[hantsy]

@snicoll

UserRepository is a Spring Data JPA interface. I have to disable JPA in projects to use @JsonTest?

I found @DataJpaTest, @WebMvcTest have the same problems, they do not load ApplicationContext as the @SpringBootTest, I really do not know the design purpose of the @JsonTest, @DataJpaTest, @WebMvcTest if they can not be used freely.

[snicoll]

This is explained in the documentation. It's test slicing (only starting a part of the actual application to have tests that are isolated on a single concept). DataJpaTest for instance only starts JPA (and does not scan your controllers, etc. If that's not what you want, just keep @SpringBootTest and use the new Autoconfigure annotations. In your case that should be AutoConfigureJsonTesters.

The new infra also auto-detects your @SpringBootApplication. If you have a bunch of requirements there, that's not going to work.

[wimdeblauwe]

I wanted to test @JsonTest and I believe I have the same issue. I added a new test class that is only annotated with @JsonTest. When I run it, it tries to load my DatabaseUserDetailsService as well, but it seems the entityManagerFactory is not present:

No bean named 'entityManagerFactory' is defined

Like @hantsy, I am wondering how you can use this in a real world application.

If I understand things correctly, it would be more clear to have an annotation on the JacksonTester field instead of the class or Spring Boot should only create the ObjectMapper and the @JsonComponent beans (Of course, those beans might be dependent on other beans).

[philwebb]

@wimdeblauwe Do you have a sample that you can share? The JsonExcludeFilter class tries to filter out non-relevant beans so I'm wondering why DatabaseUserDetailsService is still included.

I'm not following what you mean about the "annotation on JacktonTest" can you clarify? It is possible to use that class directly with your own ObjectMapper. Use JacksonTester.initFields (see the class-level Javadoc).

[wimdeblauwe]

@philwebb I have added a sample project at https://github.com/wimdeblauwe/spring-boot-issue-5776/tree/master. See the README there for some more info.

[philwebb]

@wimdeblauwe The problem you're seeing is because you have directly declared @EnableJpaRepositories, @EnableJpaAuditing and @ComponentScan annotations. You can fix @ComponentScan by adding an additional filter:

@ComponentScan(excludeFilters = { @Filter(pattern = ".*TestConfiguration", type = FilterType.REGEX),
        @Filter(type = FilterType.CUSTOM, classes = TypeExcludeFilter.class) })

The other ones are a little more tricky to fix and I'm not sure what we should do. You might be better off using a full @SpringBoot test in combination with @AutoConfigureJsonTesters, or using JacksonTester.initFields.

[wimdeblauwe]

The @ComponentScan is only there to exclude any inner classes that are Spring configurations just for a unit test. Without that, the application might pick beans from those tests contexts. What would be the recommended way to handle that?

I have @EnableJpaRepositories and @EnableJpaAuding because I am using Spring Data JPA. Are you saying I don't need to declare those?

[philwebb]

@wimdeblauwe Boot 1.4 adds a new @TestComponent and @TestConfiguration annotations which can be used on components that Spring Boot's default scanning should ignore (the JavaDoc has more details).

You can safely drop @EnableJpaRepositories and it will be auto-configured. I'm not sure about @EnableJpaAuding, that one might be a problem.
