java - How to capture variable parameters with Mockito?

Question

There is a method which has variable parameters:

class A {
    public void setNames(String... names) {}
}

Now I want to mock it with mockito, and capture the names passed to it. But I can't find a way to capture any number of names passed, I can only get them like this:

ArgumentCaptor<String> captor1 = ArgumentCaptor.fromClass(String.class);
ArgumentCaptor<String> captor2 = ArgumentCaptor.fromClass(String.class);

A mock = Mockito.mock(A.class);
mock.setNames("Jeff", "Mike");
Mockito.verity(mock).setNames(captor1.capture(), captor2.capture());
String name1 = captor1.getValue(); // Jeff
String name2 = captor2.getValue(); // Mike

If I pass three names, it won't work, and I have to define a captor3 to capture the 3rd name.

How to fix it?

Answer 1

Mockito 1.10.5 引入了这个特性。

对于问题中的代码示例，这是捕获可变参数的一种方法：

    ArgumentCaptor<String> varArgs = ArgumentCaptor.forClass(String.class);
    A mock = Mockito.mock(A.class);
    mock.setNames("Jeff", "Mike", "John");
    Mockito.verify(mock).setNames(varArgs.capture());

    //Results may be validated thus:
    List<String> expected = Arrays.asList("Jeff", "Mike", "John");
    assertEquals(expected, varArgs.getAllValues());

有关详细信息，请参阅ArgumentCaptor javadoc。
