Jersey 2, Spring framework, Mockito test example

The problem I ran into while using Jersey 2 in combination with Spring Framework was, that I was unable to wire in Mockito mocks into Jersey 2 resources while doing integration test. I created this sample application to show you how to solve this problem.

For jersey 2.8 and above you can checkout my solution here

Problem

I want to be able to test a Jersey 2 resource (get status codes, etc...) without creating a complete Spring Application Context.

Goals

The example application has the following goals:

  • Show how to wire a mocked context into resources
  • How gain control over mocked item with Mockito
  • Show you if you're Jersey 2 behaviour is correct

Solution

I've created the following solution.

The SpringContextJerseyTest is a copy of the JerseyTest, the Jersey test didn't allow you to have access to the Spring ApplicationContext. The can be done with SpringContextJerseyTest.getSpringApplicationContext().

I'm able to create mocked objects with Mockito using a factory pattern in the MockFactory. The MockFactory is able to create a mocked version of SomeService.

Testing

You're able to run the test by running this command, or run the test in you're IDE.

mvn test

The real implementation can also be tested, you're able to run the application with the following command.

mvn jetty:run

And when the application is started, you can test the resource with following command (OSX tested only)

curl -i http://localhost:8080/resources/someaction

You should expect a response like this
