Mockito.any() for <T>

Question

I want to mock a method with signature as:

public <T> T documentToPojo(Document mongoDoc, Class<T> clazz) 

I mock it as below:

Mockito.when(mongoUtil.documentToPojo(Mockito.any(Document.class), Mockito.any(WorkItemDTO.class))) 

But I get error as:

The method documentToPojo(Document, Class<T>) in the type MongoUtil is not applicable for the arguments (Document, WorkItemDTO)

Is there any method in Mockito which will help me mock for T?

Answer 1

Note that documentToPojo takes a Class as its second argument. any(Foo.class) returns an argument of type Foo, not of type Class<Foo>, whereas eq(WorkItemDTO.class) should return a Class<WorkItemDTO> as expected. I'd do it this way:

when(mongoUtil.documentToPojo(     Mockito.any(Document.class),     Mockito.eq(WorkItemDTO.class))).thenReturn(...); 

Answer 2

You can match a generic Class<T> argument using simply any( Class.class ), eg.:

Mockito.when( mongoUtil.documentToPojo( Mockito.any( Document.class ),                                         Mockito.any( Class.class ) ) ); 

Cheers,
