10  * Generic interface to be used for configuring mock's answer for a two argument invocation that returns nothing.
11  *
12  * Answer specifies an action that is executed when you interact with the mock.
13  * <p>
14  * Example of stubbing a mock with this custom answer:
15  *
16  * <pre class="code"><code class="java">
17  * import static org.mockito.AdditionalAnswers.answerVoid;
18  *
19  * doAnswer(answerVoid(
20  *     new VoidAnswer2&lt;String, Integer&gt;() {
21  *         public void answer(String msg, Integer count) throws Exception {
22  *             throw new Exception(String.format(msg, count));
23  *         }
24  * })).when(mock).someMethod(anyString(), anyInt());
25  *
26  * //Following will raise an exception with the message "boom 3"
27  * mock.someMethod("boom %d", 3);
28  * </code></pre>
