问题描述
在Java中使用Mockito如何验证一个方法只调用一次精确参数忽略对其他方法的调用?
Using Mockito in Java how to verify a method was called only once with exact parameters ignoring calls to other methods?
示例代码:
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())
}
}
应该在 TODO中做什么:不允许所有其他调用add()
部分?
尝试失败:
-
verifyNoMoreInteractions(foo);
verifyNoMoreInteractions(foo);
不。它不允许调用其他方法,如 clear()
。
Nope. It does not allow calls to other methods like clear()
.
-
verify(foo,times(0))。add(any());
verify(foo, times(0)).add(any());
不。它没有考虑到我们允许一次调用 add(1)
。
Nope. It does not take into account that we allow one call to add("1")
.
推荐答案
Mockito.verify(foo, Mockito.times(1)).add("1");
Mockito.verify(foo, Mockito.times(1)).add(Mockito.anyString());
第一个验证
检查预期的参数化调用第二个验证
检查只有一次调用添加
。
The first verify
checks the expected parametrized call and the second verify
checks that there was only one call to add
at all.
