Mockito MissingMethodInvocationException
Mockito MissingMethodInvocationException
提问于 2016-04-26 12:46:53
我知道我的问题有很多类似的问题/答案，但我仍然无法用我的测试来解决这个问题。
问题：，我试图模拟Settings类，但是Mockito抱怨这一行：
when(settings.settingsBuilder().put(new String("test"), "test").build()).thenReturn(settings)MissiongMethodInvocationException：
org.mockito.exceptions.misusing.MissingMethodInvocationException:
when() requires an argument which has to be 'a method call on a mock'.
For example:
when(mock.getArticles()).thenReturn(articles);
Also, this error might show up because:
1. you stub either of: final/private/equals()/hashCode() methods.
Those methods *cannot* be stubbed/verified.
Mocking methods declared on non-public parent classes is not supported.
2. inside when() you don't call method on mock but on some other object.我尝试过许多可能的方法，但没有结果。贝娄是实际的测试方法。
@RunWith(PowerMockRunner.class)
@PrepareForTest({Settings.class, Client.class})
public class AddressMatcherElasticTest {
private final AddressWebConfiguration configuration = mock(AddressWebConfiguration.class);
private final Settings settings = mock(Settings.class);
private final Client client = mock(Client.class);
@Test
public void match() throws Exception {
when(configuration.getClusterName()).thenReturn(new String("name"));
when(settings.settingsBuilder().put(new String("name"), "test").build()).thenReturn(settings);
AddressMatcherElastic test = new AddressMatcherElastic(configuration);
verify(configuration, times(1)).getClusterName();
}

settings是您的模拟，如果调用它，您可以告诉Mockito返回什么。
然而，settings.settingsBuilder()不返回一个模拟，这就是Mockito所抱怨的。当调用settingsBuilder时，您可以告诉Mockito返回一个模拟对象。
Builder settingsBuilder = mock(Builder.class);
when(settingsBuilder.doX()).thenReturn(...);
when(settings.settingsBuilder()).thenReturn(settingsBuilder);如果您不声明否则，则在默认情况下对对象引用返回null，请注意。
