Interface VoidMethodStubbable<T>


public interface VoidMethodStubbable<T>

Stubs void method with an exception. E.g:

 stubVoid(mock).toThrow(new RuntimeException()).on().someMethod();

 //you can stub with different behavior for consecutive method calls.
 //Last stubbing (e.g: toReturn()) determines the behavior for further consecutive calls.
 stubVoid(mock)
  .toThrow(new RuntimeException())
  .toReturn()
  .on().someMethod();

Method Detail

toThrow

VoidMethodStubbable<T> toThrow(java.lang.Throwable throwable)
Stubs void method with an exception. E.g:
 stubVoid(mock).toThrow(new RuntimeException()).on().someMethod();
 
If throwable is a checked exception then it has to match one of the checked exceptions of method signature. See examples in javadoc for Mockito.stubVoid(T)

Parameters:
throwable - to be thrown on method invocation
Returns:
VoidMethodStubbable - typically to choose void method and finish stubbing

toReturn

VoidMethodStubbable<T> toReturn()
Stubs void method to 'just return' (e.g. to not to throw any exception)

Only use this method if you're stubbing consecutive calls.

For example:

 stubVoid(mock)
   .toReturn()
   .toThrow(new RuntimeException())
   .on().foo(10);
 

See examples in javadoc for Mockito.stubVoid(T)

Returns:
VoidMethodStubbable - typically to choose void method and finish stubbing

toAnswer

VoidMethodStubbable<T> toAnswer(Answer<?> answer)
Stubs a void method with generic Answer

For Example:

 stubVoid(mock)
   .toAnswer(new Answer() {
                 public Object answer(InvocationOnMOck invocation) {
                     Visitor v = (Visitor) invocation.getArguments()[0];
                     v.visitMock(invocation.getMock());

                     return null;
                 }
             })
    .on().accept(any());
 

Parameters:
answer - the custom answer to execute.
Returns:
VoidMethodStubbable - typically to choose void method and finish stubbing

on

T on()
Choose void method for stubbing. E.g:
 stubVoid(mock).toThrow(new RuntimeException()).on().someMethod("some arg");
 
See examples in javadoc for Mockito.stubVoid(T)
