Unit Testing - Spring

Question

Ich habe kleine Testklasse für meine einfache Anwendung gemacht.

Ich habe einige Probleme mit ApplicationContext und kann nicht einige Klassen autowire.

Hier ist mein Test-Klasse:

package com.myapp.adminpanel.test; 


import com.myapp.adminpanel.service.CityService; 
import org.junit.Test; 
import org.junit.runner.RunWith; 
import org.springframework.beans.factory.annotation.Autowired; 
import org.springframework.context.annotation.Bean; 
import org.springframework.context.annotation.Configuration; 
import org.springframework.test.context.ContextConfiguration; 
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; 
import org.springframework.test.context.support.AnnotationConfigContextLoader; 


import static org.junit.Assert.*; 

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(loader = AnnotationConfigContextLoader.class) 
public class CityServiceTest { 

    @Configuration 
    static class ContextConfiguration { 

     @Bean 
     public CityService getCityService() { 
      return new CityService(); 
     } 
    } 

    @Autowired 
    private CityService cityService; 

    @Test 
    public void testServicePackage() { 
     assertEquals("com.logate.adminpanel.service.CityService",this.cityService. getClass().toString()); 
    } 
} 

Der folgende Code: java.lang.IllegalStateException: Failed to load ApplicationContext

jemand mir mit diesem helfen?

Vielen Dank.

Es ist nicht Ihren Test jede Konfiguration verwendet gerichtet haben zu laden. Say Kontextkonfiguration welche Konfiguration zu verwenden:

@RunWith(SpringJUnit4ClassRunner.class) 
@ContextConfiguration(classes = ContextConfiguration.class) 
public class CityServiceTest { 

Es ist besser, Ihre ContextConfiguration etwas weniger irreführend (MyTestConfig usw.)

Zweiter Ansatz umbenennen, können Sie Ihren Test als Konfiguration mit Anmerkungen versehen:

Aber ich sehe keinen Sinn darin, weil Sie Ihre Bean-Deklaration in anderen Tests nicht wiederverwenden können und Sie können Objekt nur mit Neu erstellen:

private CityService cityService = new CityService(); 

So ist die beste Wahl, um Ihre config separate Klasse extrahieren und übergeben es an ContextConfiguration als Klassen Argument
