春ブーツの統合は、テスト別のmavenモジュール

Question

内の既存のBeanを拾うことができ、エラーをスローしていない私は、次のMavenベースのプロジェクト構造

product-app 
    product-web 
    product-service 
    product-integration-tests 

を持っている私は希望product-serviceモジュールで書かれたMailClientServiceサービスがありますに統合テストをするのが好きです。統合テストは明らかにproduct-integration-testsモジュールに書かれています。

product-integration-testsモジュールのpomには、すでにproduct-web moduleが追加されています。

しかし、問題は、統合テストの実行中にMailClientServiceのBeanを構築できず、実行時例外がスローされていることです。

例外

Answer 1

よく見ると、あなたがインスタンスを作成することができますMailClientServiceのインスタンスであるが、Springだけではは、@Autowiredアノテーションを使ってインスタンスをテストクラスに挿入します。

No qualifying bean of type [com.radial.hostedpayments.service.MailClientService] found for dependency [com.radial.hostedpayments.service.MailClientService]: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException 

テストクラスで使用できるMailClientServiceクラスのSpring Beanインスタンスを提供する必要があります。 @ContextConfigurationアノテーションによってこれを行うことができます。

ステップ1 - あなたのMailServiceClientを公開@Configurationクラスを作成します。

@Configuration 
public class TestConfig { 

    @Bean 
    public JavaMailSender mailSender() { 
     // example of returning a mock object 
     return Mockito.mock(JavaMailSender.class); 
    }  

    @Bean 
    public GreenMail smtpServer() { 
     // another mock 
     return Mockito.mock(GreenMail.class); 
    } 

    @Bean 
    public MailClientService mailClientService(){ 
     // this could also be used to return a Mock object 
     return new MailClientService(); 
    } 
} 

ステップ2 - あなたのテストに設定クラスを追加します。

... 
@ContextConfiguration(classes = {TestConfig.class}) 
public class MailClientServiceIntegrationTest { 
... 

を私がどのように表示するには、これを編集しましたconfigクラスからモックを返すことができます。あなたの実装では、JavaMailSenderは自動で作成されますが、GreenMail変数は自動作成されません。
