問(wèn)題描述

在 Java 中使用 Mockito 如何驗(yàn)證一個(gè)方法只被調(diào)用了一次，而忽略了對(duì)其他方法的調(diào)用?

Using Mockito in Java how to verify a method was called only once with exact parameters ignoring calls to other methods?

示例代碼:

public class MockitoTest {

    interface Foo {
        void add(String str);
        void clear();
    }


    @Test
    public void testAddWasCalledOnceWith1IgnoringAllOtherInvocations() throws Exception {
        // given
        Foo foo = Mockito.mock(Foo.class);

        // when
        foo.add("1"); // call to verify
        foo.add("2"); // !!! don't allow any other calls to add()
        foo.clear();  // calls to other methods should be ignored

        // then
        Mockito.verify(foo, Mockito.times(1)).add("1");
        // TODO: don't allow all other invocations with add() 
        //       but ignore all other calls (i.e. the call to clear())
    }

}

TODO: 不允許使用 add() 部分的所有其他調(diào)用中應(yīng)該做什么?

What should be done in the TODO: don't allow all other invocations with add() section?

已經(jīng)嘗試失敗:

1. verifyNoMoreInteractions(foo);

不.它不允許調(diào)用其他方法，例如 clear().

Nope. It does not allow calls to other methods like clear().

1. verify(foo, times(0)).add(any());

不.它沒(méi)有考慮到我們?cè)试S一次調(diào)用 add("1").

Nope. It does not take into account that we allow one call to add("1").

推薦答案

Mockito.verify(foo, Mockito.times(1)).add("1");
Mockito.verify(foo, Mockito.times(1)).add(Mockito.anyString());

第一個(gè) verify 檢查預(yù)期的參數(shù)化調(diào)用，第二個(gè) verify 檢查是否只有一次對(duì) add 的調(diào)用.

The first verify checks the expected parametrized call and the second verify checks that there was only one call to add at all.
