的Mockito。验证方法参数是否为特定类

Question

I have a method:

void putObject(<T extends BaseEntity> param)

Have some test where I mock this method, but I wonder, how to verify that method was called with parameter of particular class? Tried to do it in such ways:

verify(foo).putObject((SomeClass)anyObject());
------
verify(foo).putObject(any(SomeClass.class));
------
ArgumentCaptor<SomeClass> parameter = ArgumentCaptor
            .forClass(SomeClass.class);
verify(foo).putObject(parametr);

Works only the second variant with any() , but it doesn t check class of parameter`. So if it is possible to verify that method get any object of particular class?

Answer 1

User Matcher documentation isA() method.

public static <T> T isA(java.lang.Class<T> clazz)

That will solve your problem.

verify(foo).putObject(isA(SomeClass.class));

Answer 2

Actually you can check with ArgumentCaptor.

ArgumentCaptor<SomeClass> parameterCaptor = ArgumentCaptor
            .forClass(SomeClass.class);
verify(foo).putObject(parameterCaptor.capture());

SomeClass instance = parameterCaptor.getValue();
// check intance.getX()
// check instance.getY()
