How to use Junit with Demoiselle 2.4.2?

Question

Hello

I have a project with the following profile:

• Eclipse Luna
• Java 6
• JSF 2.2/Primefaces 5.3
• Jboss 7
• Demoiselle 2.4.2.

The application already works, the problem is in the execution of test cases of the Junit 4.12. The test case shown below corresponds to the invocation of a method of a Managed bean annotated with @ViewController, that is, is the test of a backing bean one-page XHTML:

@RunWith(DemoiselleRunner.class)
public class CaixaAberturaTests {

    @Inject
    CaixaOperacaoEditMB caixaOperacao;

    @Test
    public void shouldConfirmarAberturaParaUsuarioLogado() {
        // Arrange
        caixaOperacao.setSaldoInicial(new BigDecimal(100.00));

        // Act
        String destino = caixaOperacao.confirmarAbertura();

        // Assert
        assertNotNull(destino);
    }
}

When executing, the exception is thrown on the session line Arrange, which is nothing more than the attribution of a value to a property. The code of such a method follows below:

public void setSaldoInicial(BigDecimal value) {
  saldoInicial = value; 
}

However, the method never gets to be executed, it is intercepted before and in this process is that the exception is thrown, as stack next:

I’d like some tips to solve the case.

Thanks in advance!

Alex the problem seems in the injection of Managedbean, probably Démoiselle is not able to do the injection because it is a class managed by JSF. Usually the rules of the business are in the classes with the annotation @Bussinesscontroller. I had not yet tried to inject a Managedbean. Don’t you have a Caixaoperacaobc class where you confirm Bertura() is actually being realized? If you do, change the test class and change your method to receive the balance (or the object that contains it) and insert that class into your test. Managedbean will basically get the data from the screen and direct to the respective business class to carry out the rules. In that case you wouldn’t need it for your tests.
