jerseytest | Writing lightweight REST integration tests with the Jersey | Code Editor library

Ran into a few errors as I am upgrading jdk11 and jersey but this one particularly stumped. So jersey 2.28 is supposedly compatible with OpenJDK11 and fixed some issues that was previously in 2.25.1, so I upgraded it

I also saw this already, not a working solution - Jersey Spring Maven java.lang.NoClassDefFoundError: org/glassfish/jersey/hk2/HK2InjectionManager

In my gradle build, failed on this task:

> Task :ods-impl:test FAILED

Under my task for this, here is the list of dependencies

I'm trying to mock a controller/resource including the jax-rs layer. The class has dependencies that need to be injected. It however also has some String values that are injected using a qualifier interface.

Basically, I'm using JerseyTest to run a single controller and use HK2 for dependency injection. I created a ResourceConfig and registered a AbstractBinder to bind the injected classes.

This works fine for regular injected dependencies, but when the the additional @SomeQualifierInterface annotation is added, it crashes with the following error:

When testing with JerseyTest, I am having trouble to bind to a:

I'm building a Java REST API with Jersey 2.27 and in my test class (as shown below) I get the following compile error: Cannot resolve method 'bindFactory(java.lang.Class)'.

I don't get why this is not compiling. The bindFactorymethod has one parameter of type Class>, and my factory class is implementing Supplier as shown below. Can someone explain to me why this won't compile?

PS: Tthese are only snippets of the full code to make things clearer.

Trying to test a fairly simple JAX-RS endpoint

I configured jackson so that it gives me a smiple string representation if java.time.LocalDate and java.time.LocalDateTime. This works find in the serialization process, e.g when I get data on the REST api.

It doesn't work the other way round though. When I try to send data to the server and the JSON should be parsed to java objects this exception is thrown:

javax.ws.rs.client.ResponseProcessingException: com.fasterxml.jackson.databind.JsonMappingException: Can not construct instance of java.time.LocalDateTime: no String-argument constructor/factory method to deserialize from String value ('2018-04-19T14:10:30.903')

After a few hours of research I managed to get it to work, but only with the attributes I annotated with @JsonDeserialize(using = LocalDateDeserializer.class) or @JsonDeserialize(using = LocalDateTimeDeserializer.class) respectively.

In my opinion it would be ideal, if I could define these mappings in one central place.

ObjectMapper configuration:

I know that the error "MessageBodyProvider" not found for application type question has been asked a lot of time, but my case is a bit different.

The REST works fine when I manually invoke the REST API through Fiddler or in the browser. So there seems to something odd with the test. I can't get my head around this.

I am creating a application that should be able to create an account using a REST api. When I wrote the AccountController.java class everything worked fine. I used postman to verify that I got the right response.

So my AccountController.java works correctly but the unit test I wrote with it don't work. When the unit test is executed it returns a NullPointerException which results in a InternalServerError within the REST API. While debugging i found out that if I remove the use of UriInfo in AccountController.java and return Response.ok() instead of created the test is successfull.

So my question is. How do i properly test/mock a method that returns and URI?

Bellow are all relevant classes and dependencies. The Account.java class is in another package. But both the main application as the project that contains Account.java are part of the same parent pom. I am not sure if this is relevant to my question.

I am trying to write some integration tests for an application that uses Jersey with some Spring DI. Tests always come back as a 500 with no real explaination. Grizzly appears to start ok and boots up my hibernate connections just fine. Here is the error trace along with all of relevant files sans the class under test. I think it may be an issue with Grizzly and the configuration but I cant find anything that seems to work including switching to a webappcontext.
