Question

I want to throw a ContentIOException from a method whose signature look like this.

public void putContent(InputStream is) throws ContentIOException.

When I try to throw ContentIOException from Mockito like such:

when(StubbedObject.putContent(contentStream)).thenThrow(ContentIOException.class);

I get the following compilation error:

The method when(T) in the type Mockito is not applicable for the arguments (void).

What am I doing wrong?

Take a look at this reference in the official API. You want to reverse the way your call is made and adjust the argument too, since this is a void method that you expect to throw an exception.

doThrow(new ContentIOException()).when(StubbedObject).putContent(contentStream);
