Mockito.any() for <T>
提问by Rajesh Kolhapure
I want to mock a method with signature as:
我想模拟一个带有签名的方法：
public <T> T documentToPojo(Document mongoDoc, Class<T> clazz)
I mock it as below:
我嘲笑它如下：
Mockito.when(mongoUtil.documentToPojo(Mockito.any(Document.class), Mockito.any(WorkItemDTO.class)))
But I get error as:
但我得到的错误是：
The method documentToPojo(Document, Class<T>)in the type MongoUtilis not applicable for the arguments (Document, WorkItemDTO)
documentToPojo(Document, Class<T>)类型中的方法MongoUtil不适用于参数(Document, WorkItemDTO)
Is there any method in Mockito which will help me mock for T?
Mockito 中是否有任何方法可以帮助我模拟 T？

Note that documentToPojotakes a Classas 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:
请注意，documentToPojo将Class作为其第二个参数。any(Foo.class)返回 type 的参数，而Foo不是 type Class<Foo>，而eq(WorkItemDTO.class)应该Class<WorkItemDTO>按预期返回 a 。我会这样做：
when(mongoUtil.documentToPojo(
Mockito.any(Document.class),
Mockito.eq(WorkItemDTO.class))).thenReturn(...);

You can match a generic Class<T>argument using simply any( Class.class ), eg.:
您可以Class<T>使用 simple匹配泛型参数any( Class.class )，例如：
Mockito.when( mongoUtil.documentToPojo( Mockito.any( Document.class ),
Mockito.any( Class.class ) ) );

You can do it using ArgumentMatchers.any() qualified with the type, like so:
您可以使用带有类型限定的 ArgumentMatchers.any() 来完成，如下所示：
Mockito.when(
mongoUtil.documentToPojo(
Mockito.any(Document.class),
ArgumentMatchers.<Class<WorkItemDTO>>any()
)
).thenReturn(...);
