otasco

Allows testing class under test without creating useless setters for dependencies.

Makes the test class more readable.

  public class InvoiceManagerTest { 
      @ClassUnderTest private InvoiceManager manager;
      
      @Dependency private InvoiceCalculator invoiceCalculator;
     
      @Dependency private InvoiceDao invoiceDao;
      
      @Before public void setup() {
          invoiceCalculator = new InvoiceCalculator();
          invoiceDao = new InvoiceDao();
          manager = new InvoiceManager();
          Otasco.init(this);
      }
  }

Possibly using Mockito (or your favorite mocking library)

  @RunWith(OtascoMockitoJUnitRunner.class)
  public class InvoiceManagerTest {
      @ClassUnderTest private InvoiceManager manager;
                  
      @Dependency
      @Mock
      private InvoiceCalculator invoiceCalculator;
                  
      @Dependency
      @Mock
      private InvoiceDao invoiceDao;
                  
  }
