“Address already in use: bind” exception lors de l'exécution de Gradle JUnit tests

Je suis en utilisant le Printemps de Démarrage 1.2.1.LIBÉRATION, JUnit4, et Gradle 2.1 pour un service RESTful et suis en train de définir un fichier de propriétés qui comprend et/ou remplace les valeurs qui seront utilisées dans JUnit tests seulement.
Tous les tests à exécuter sans problème lorsqu'il est invoqué comme un test JUnit. Toutefois, lorsque ces mêmes tests sont exécutés au cours d'une gradle "construire" ou "test" de la tâche, ils ne parviennent pas à l'exception de "Causé par: java.lang.IllegalStateException: Tomcat connecteur à l'échec de l'état" avec la cause sous-jacente comme "java.net.BindException: Adresse déjà en cours d'utilisation: bind".

Il y a plusieurs classes de test qui nécessitent un contexte d'application pour exécuter la commande.

Pour faciliter les autres valeurs par l'intermédiaire d'un fichier de propriétés, j'ai inclus TestPropertySource()

Est-il Gradle configuration nécessaire pour faire ce travail?

ControllerTest classe

@RunWith(SpringJUnit4ClassRunner.class)
@WebAppConfiguration
@SpringApplicationConfiguration(classes = RESTAdapter.class)
@TestPropertySource(locations="classpath:application-junit.properties")
public class ControllerTest {

    @Value("${test.token}")
    private String token;

    @Autowired
    private WebApplicationContext wac;

    private MockMvc mockMvc;

    @Before
    public void setup() {
          this.mockMvc = MockMvcBuilders.webAppContextSetup(this.wac).build();
    }

    public void TestMockMvc(String[] strings) throws Exception{

        mockMvc.perform(URL_all_paramters, strings)
            .param(Constants.PARAM_TOKEN, token)
            .accept(Constants.APPLICATION_JSON_UTF8))
            .andDo(print())
            .andExpect(status().isOk())
            .andExpect(content().contentType(Constants.APPLICATION_JSON_UTF8))
            .andExpect(content().json(strings[strings.length-1]));
    }
  }

Gradle est de le faire tourner un autre exemple de l'embedded serveur Tomcat, provoquant la liaison exception. Ajout de l'indicateur de débogage à Gradle de l'exécution révélé cela.

Gradle du test, forEvery des biens dont la valeur par défaut est 0 (pas de maximum). Il est décrit ici comme

"Le nombre maximum de classes de test à exécuter dans une fourche de test
processus. La fourche processus de test doivent être redémarrés lorsque cette limite est
atteint. La valeur par défaut est 0 (pas de maximum)."

JUnit tests sont exécutés en parallèle, et en raison des multiples contrôleur de tests à un contexte d'application à exécuter, le même port est utilisé sur Tomcat initialisation.

On pourrait s'en tirer avec adjonction de construire.gradle, même si ce serait ralentir considérablement les tests:

construire.gradle:
```
test{
forkEvery = 1
}
```
Au lieu de cela, il suffit de remplacer le serveur Tomcat port, comme indiqué ici, dans l'autre les propriétés de fichier Tomcat initialiser avec un port non utilisé à chaque fois qu'il a lancé.

application-junit.propriétés:
```
server.port=0
```
