当我尝试模拟存储库时出错

Question

我试图模拟一个存储库并返回保存的同一个对象。

这是我的代码片段：

public TransactionType createTransactionType(TransactionTypeEnum type) { 
     TransactionType transactionType = new TransactionType(); 
     transactionType.setStatus(type.code()); 
     transactionType.setDescription(type.name()); 

     return transactionTypeRepository.save(transactionType); 
} 

我试图假装是这样的：

1.

public TransactionTypeRepositoryMockBuilder doSave(){ 
      Mockito.when(this.target.save(Mockito.any(TransactionType.class))) 
      .then(new SaveMock<>()) 
      .then(AdditionalAnswers.returnsFirstArg()); 
      return this; 
} 

2.

public TransactionTypeRepositoryMockBuilder doSave(){ 
       Mockito.when(this.target.save(Mockito.any(TransactionType.class))).then(new SaveMock<>()); 
       return this; 
} 

3.

public TransactionTypeRepositoryMockBuilder doSave(){ 
        Mockito.when(this.target.save(Mockito.any(TransactionType.class))).thenReturn(new TransactionType()); 
        return this; 
} 

4.

public TransactionTypeRepositoryMockBuilder doSave(){ 

    Mockito.when(this.target.save(Mockito.any(TransactionType.class))).then(AdditionalAnswers.returnsFirstArg()); 

     return this; 

    } 

我的生成器类

public class TransactionTypeRepositoryMockBuilder { 
    private final TransactionTypeRepository target; 

    private TransactionTypeRepositoryMockBuilder() { 
     this.target = Mockito.spy(TransactionTypeRepository.class); 
    } 

    public static TransactionTypeRepositoryMockBuilder create(){ 
     return new TransactionTypeRepositoryMockBuilder(); 
    } 

    public TransactionTypeRepository build() { 
     return this.target; 
    } 

    public TransactionTypeRepositoryMockBuilder doSave(){ 
     Mockito.when(this.target.save(Mockito.any(TransactionType.class))).thenReturn(new TransactionType()); 
     return this; 
    } 

} 

我收到此错误： _java.lang.NoSuchMethodError：org.mockito.invocation.InvocationOnMock.getArgumentAt（ILjava/lang/Class;）Ljava/lang/Object; _ 我做错了什么？

Answer 1

mockito-2.1中有一个update。方法getArgumentAt()采用不同的参数。所以你必须在你的mockito罐子里有不一致的地方。

when(userDeviceService.save(any(UserDevice.class))) .then(invocation -> invocation.getArgumentAt(0, UserDevice.class)); Now:

when(userDeviceService.save(any())) .then(invocationOnMock -> invocationOnMock.getArgument(0));
