You can easily create your own HandlerMethod without mocking. There's a constructor that accepts an Object (the controller) and a Method (the controller method). The easiest way to get a Method is to simply call Class.getMethod(). What you want to do is just create a dummy controller class, and then use that class to get the method. For example

class TestController {
    @Custom
    public void testMethod() {}
}

Method method = TestController.class.getMethod("testMethod");
TestController controller = new TestController();
HandlerMethod handlerMethod = new HandlerMethod(controller, method);

Custom annotation = handlerMethod.getMethodAnnotation(Custom.class);

It's that easy. Below is a complete test.

public class HandlerInterceptorTest {

    @Target(ElementType.METHOD)
    @Retention(RetentionPolicy.RUNTIME)
    private @interface Custom {
    }

    private static class MyHandlerInterceptor implements HandlerInterceptor {

        @Override
        public boolean preHandle(HttpServletRequest req, HttpServletResponse res, Object handler) {
            if (handler instanceof HandlerMethod) {
                HandlerMethod handlerMethod = (HandlerMethod) handler;
                Custom annotation = handlerMethod.getMethodAnnotation(Custom.class);
                if (annotation != null) {
                    return true;
                }
            }
            return false;
        }
    }

    private static class TestController {
        @Custom
        public void testMethodWithAnnotation() {}

        public void testMethodWithoutAnnotation() {}
    }

    @Test
    public void testMethodWithAnnotation() throws Exception {
        Method method = TestController.class.getMethod("testMethodWithAnnotation");
        TestController controller = new TestController();
        HandlerMethod handlerMethod = new HandlerMethod(controller, method);

        MyHandlerInterceptor interceptor = new MyHandlerInterceptor();
        boolean result = interceptor.preHandle(null, null, handlerMethod);

        assertTrue(result);
    }

    @Test
    public void testMethodWithoutAnnotation() throws Exception {
        Method method = TestController.class.getMethod("testMethodWithoutAnnotation");
        TestController controller = new TestController();
        HandlerMethod handlerMethod = new HandlerMethod(controller, method);

        MyHandlerInterceptor interceptor = new MyHandlerInterceptor();
        boolean result = interceptor.preHandle(null, null, handlerMethod);

        assertFalse(result);
    }

Mockito 2 now supports final classes and methods!

But for now that's an "incubating" feature. It requires some steps to activate it which are described in What's New in Mockito 2:

Mocking of final classes and methods is an incubating, opt-in feature. It uses a combination of Java agent instrumentation and subclassing in order to enable mockability of these types. As this works differently to our current mechanism and this one has different limitations and as we want to gather experience and user feedback, this feature had to be explicitly activated to be available ; it can be done via the mockito extension mechanism by creating the file src/test/resources/mockito-extensions/org.mockito.plugins.MockMaker containing a single line:
mock-maker-inline
After you created this file, Mockito will automatically use this new engine and one can do :
 final class FinalClass {
   final String finalMethod() { return "something"; }
 }

 FinalClass concrete = new FinalClass(); 

 FinalClass mock = mock(FinalClass.class);
 given(mock.finalMethod()).willReturn("not anymore");

 assertThat(mock.finalMethod()).isNotEqualTo(concrete.finalMethod());
In subsequent milestones, the team will bring a programmatic way of using this feature. We will identify and provide support for all unmockable scenarios. Stay tuned and please let us know what you think of this feature!

https://stackoverflow.com/questions/14292863/how-to-mock-a-final-class-with-mockito

If you want to test using the URL, then you will need to start a server from your test. You can explicitly start an embedded server, which is pretty common for tests. Something like

public class MyResourceTest {

    public static final String BASE_URI = "http://localhost:8080/api/";
    private HttpServer server;

    @Before
    public void setUp() throws Exception {
        final ResourceConfig rc = new ResourceConfig(Service.class);
        server = GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI), rc);       
    }

    @After
    public void tearDown() throws Exception {
        server.stop();
    }

    @Test
    public void testService() {
        Client client = ClientBuilder.newClient();
        WebTarget target = client.target(BASE_URI).path("service");
        ...
    }
}

It's basically an integration test. You're starting the Grizzly container and loading a ResourceConfig to the server with only the Service class. Of course you could add more classes to the configuration. You can use "real" resource config if you wanted.

The above test uses this dependency

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-grizzly2-http</artifactId>
    <version>${jersey2.version}</version>
</dependency>

Another option, which is the one I prefer, is to make use of the Jersey Test Framework, which will start an embedded container for you. A test might look something more like

public class SimpleTest extends JerseyTest {
 
    @Override
    protected Application configure() {
        return new ResourceConfig(Service.class);
    }
 
    @Test
    public void test() {
        String hello = target("service").request().get(String.class);
    }
}

Using this dependency

<dependency>
    <groupId>org.glassfish.jersey.test-framework.providers</groupId>
    <artifactId>jersey-test-framework-provider-grizzly2</artifactId>
    <version>${jersey2.version}</version>
    <scope>test</scope>
</dependency>

And embedded Grizzly container will get started under the hood, with your ResourceConfig configuration. In both examples above it is assumed the @Path value for the Service class is service, as you can see in the test URLs.

Some Examples

UPDATE

If you're not using Maven, here are the jars you will need to run an embedded Grizzly container for the Jersey Test Fraemwork

enter image description here

I usually search for all my jars here. You can select the version and there should be a link in the next page, to download. You can use the search bar to search for the others.

Here's a simple running example, once you have all the jars

import com.sun.jersey.api.client.WebResource;
import com.sun.jersey.api.core.DefaultResourceConfig;
import com.sun.jersey.spi.container.servlet.WebComponent;
import com.sun.jersey.test.framework.JerseyTest;
import com.sun.jersey.test.framework.WebAppDescriptor;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import junit.framework.Assert;
import org.junit.Test;

public class SimpleTest extends JerseyTest {
    
    @Path("service")
    public static class Service {
        @GET
        public String getTest() { return "Hello World!"; }
    }

    public static class AppConfig extends DefaultResourceConfig {
        public AppConfig() {
            super(Service.class);
        }
    }
    
    @Override
    public WebAppDescriptor configure() {
        return new WebAppDescriptor.Builder()
                .initParam(WebComponent.RESOURCE_CONFIG_CLASS, 
                           AppConfig.class.getName())
                .build();
    }
    
    @Test
    public void doTest() {
        WebResource resource = resource().path("service");
        String result = resource.get(String.class);
        Assert.assertEquals("Hello World!", result);
        System.out.println(result);
    }
}

You're most likely not going to have the resources and ResourceConfig in the same class as the test, but I just want to keep it simple and all visible in one class.

Whether you are using a web.xml or a ResourceConfig subclass (as shown above), you can cut down what you test by using a separate ResourceConfig, built in the test class, as I have done. Otherwise, if you are using your normal ResourceConfig class, you can just replace it in the configure method.

The configure method, is pretty much just building a web.xml file, just in Java code. You can see different methods in the WebAppDescriptor.Builder, like initParam, which is the same as an <init-param> in your web xml. You can simply use the string in the arguments, but there are some constants, as I used above.

The @Test is you usual JUnit test that will run. It is using the Jersey Client. But instead of creating the Client, you can simply just use the preconfigured Client by just accessing the resource() method, which returns a WebResource. If you are familiar with the Jersey Client, then this class should not be new to you.

The right thing to do is to restructure your code to make it more testable as shown below. Restructuring your code to remove the direct dependency on Date will allow you to inject different implementations for normal runtime and test runtime:

interface DateTime {
    Date getDate();
}

class DateTimeImpl implements DateTime {
    @Override
    public Date getDate() {
       return new Date();
    }
}

class MyClass {

    private final DateTime dateTime;
    // inject your Mock DateTime when testing other wise inject DateTimeImpl

    public MyClass(final DateTime dateTime) {
        this.dateTime = dateTime;
    }

    public long getDoubleTime(){
        return dateTime.getDate().getTime()*2;
    }
}

public class MyClassTest {
    private MyClass myClassTest;

    @Before
    public void setUp() {
        final Date date = Mockito.mock(Date.class);
        Mockito.when(date.getTime()).thenReturn(30L);

        final DateTime dt = Mockito.mock(DateTime.class);
        Mockito.when(dt.getDate()).thenReturn(date);

        myClassTest = new MyClass(dt);
    }

    @Test
    public void someTest() {
        final long doubleTime = myClassTest.getDoubleTime();
        assertEquals(60, doubleTime);
    }
}

https://stackoverflow.com/questions/11887799/how-to-mock-new-date-in-java-using-mockito

You could refactor MyClass so that it uses dependency injection. Instead of having it create an AnythingPerformerClass instance you could pass in an instance of the class to the constructor of MyClass like so :

class MyClass {

   private final AnythingPerformerClass clazz;

   MyClass(AnythingPerformerClass clazz) {
      this.clazz = clazz;
   }

   public boolean performAnything() {         
     return clazz.doSomething();        
   }
}

You can then pass in the mock implementation in the unit test

@Test
public void testPerformAnything() throws Exception {
   AnythingPerformerClass mockedPerformer = Mockito.mock(AnythingPerformerClass.class);
   MyClass clazz = new MyClass(mockedPerformer);
   ...
}

Alternatively, if your AnythingPerformerClass contains state then you could pass a AnythingPerformerClassBuilder to the constructor.

proguard-maven-plugin will obfuscate the primary artifact of your project, not the secondary artifact jar-with-dependencies that the maven-assembly-plugin generated.

You need to configure the plugin to obfuscate the jar-with-dependencies by specifying the injar attribute:

Specifies the input jar name (or wars, ears, zips) of the application to be processed.

<injar>${project.build.finalName}-jar-with-dependencies.jar</injar>

Now, there is also a problem in the order of execution of plugins in your POM: we need to make sure that the maven-assembly-plugin is executed before the proguard-maven-plugin. As such, it is best to define an explicit execution for the maven-assembly-plugin bound to the package phase instead of manually invoking it from the command line with assembly:single. This would be the configuration:

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <executions>
        <execution>
            <id>assembly</id>
            <goals>
                <goal>single</goal>
            </goals>
            <phase>package</phase>
            <configuration>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
            </configuration>
        </execution>
    </executions>
</plugin>

and then, you just need to make sure that the proguard-maven-plugin plugin configuration is after that in your POM.

Having done that, invoking Maven with mvn clean install will result in an obfuscated jar with dependencies.

To test with your actual POM, I added two repositories:

https://repo.spongepowered.org/maven to resolve the spongeapi dependency.
http://maven.restlet.com to resolve the org.restlet.jse dependencies.

With those 2 dependencies, warnings were generated by ProGuard because the org.restlet.ext.jackson dependency utilizes com.sun.msv.* classes that are not on the buildpath. Since I figure that your code is currently working, it means those classes don't need to be included and that those warnings can be ignored. As such, I added the -dontwarn option so that ProGuard doesn't error when there is a warning.

The final POM for which I was able to successfully obfuscate the jar with dependencies is the following:

The try-with-resources statement can define multiple AutoCloseable instances, both of which will be closed at the end:

try (MockedStatic<ObjectFactory> objectFactory = mockStatic(ObjectFactory.class);
     MockedStatic<Context> contextMock = mockStatic(Context.class)) {

In my case, I had a similar issue when I worked with JUnit5

@ExtendWith(MockitoExtension.class)
class MyServiceTest {
...

@InjectMocks
MyService underTest;

@Test
void myMethodTest() {
...
}

underTest was null. The cause of the problem was that I used @Test from JUnit4 package import org.junit.Test; instead JUnit5 import org.junit.jupiter.api.Test;

You need to have prepared the class calling the constructor, not the class on which the constructor is called, the following should fix you up:

@PrepareForTest(DummyTarget.class)
