inject into unit test (only XML)

fixed the issue. Will look into that further What methods in the DAO do you want to unit test? Are you not actually trying to test the DB connectivity?
Otherwise I agree with @duffymo.
final ClassPathXmlApplicationContext beanFactory = 
    new ClassPathXmlApplicationContext( "applicationContext.xml" );
AutowireCapableBeanFactory factory = beanFactory.getAutowireCapableBeanFactory();
factory.autowireBeanProperties( this, AutowireCapableBeanFactory.AUTOWIRE_BY_TYPE , true );
ProductDao dao = context.getBean( "productDao" );

Couldn't Inject Service class in grails unit test- Test Fails

this one helps. Assuming you are using a version before 2 (and JUnit instead of Spock), you need to manually add the service:
class QuoteServiceTests extends GrailsUnitTestCase {
    def quoteService 

    void setUp() {
        quoteService = new QuoteService()

    void testStaticQuote() {
        def staticQuote = quoteService.getStaticQuote()
        // ...
@TestFor(QuoteService) // Allows you to call the QuoteService via 'service'
class QuoteServiceTests {
    void testStaticQuote() {
        def staticQuote = service.getStaticQuote()
        // ...

How to inject module in test for requirejs to unit test application?

Does that help This code pattern is not unit testable. I guess someone could come up with a way of tricking RequireJS to load different module definition and unload it at the end of the test but that would be too complicated and too error prone, and wouldn't solve the problem of bad coding practice.
The pattern is not testable because inside of moduleB definition you are creating new instance of moduleA (plus loading of ModuleA is "hardcoded"). To make it testable you need to inject it. Consider something like:
define('moduleB', function() {
    var ModuleB = function(moduleA) {
        this.__moduleA = moduleA;
        this.doSomethingElse = function() {
            if(this.__moduleA.doSomething()) {
                // do something else and return

            } else {
                // do other things and return

    return ModuleB

Jersey 2 inject dependencies into unit test

Any of those help You can use the main IoC container, and just explicitly inject the test class. Jersey uses HK2 as its DI framework, and its IoC container is the ServiceLocator, which has a method inject(anyObject) that can inject any objects with dependencies that are in its registry.
For example you could do something like
public class InjectionTest {

    private TestController controller;

    public void setUp() {
        final Binder b = new AbstractBinder() {
            public void configure() {
        final ServiceLocator locator = ServiceLocatorUtilities.bind(new TestBinder(), b);

    public void doTest() {
        String response = controller.get();
        assertEquals("Hello Tests", response);
public abstract class AbstractControllerTest {

    protected ServiceLocator locator;
    private final Class<?> controllerClass;

    protected AbstractControllerTest(Class<?> controllerClass) {
        this.controllerClass = controllerClass;

    public void setUp() {
        final AbstractBinder binder = new AbstractBinder() {
            public void configure() {
        locator = ServiceLocatorUtilities.bind(new TestBinder(), binder);

    public void tearDown() {
        if (locator != null) {
public class TestControllerTest extends AbstractControllerTest {

    public TestControllerTest() {

    private TestController controller;

    public void doTest() {
        assertEquals("Hello Tests", controller.get());
