Java 如何模拟ElasticSeach客户端

我正在努力模仿下面的代码：

Client client = TransportClient.builder().settings(settings).build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

我的方法：

Settings.Builder settingsBuilder = mock(Settings.Builder.class);
when(settingsBuilder.put(new String("test"), new String("test"))).thenReturn(settings.settingsBuilder());
when(settingsBuilder.build()).thenReturn(settings);

TransportClient.Builder clientBuilder = mock(TransportClient.Builder.class);
when(clientBuilder.settings(settings)).thenReturn(clientBuilder);

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.

到目前为止，测试工作正常，但当尝试模拟客户端上使用的其他类时，Mockito抛出以下异常：

错误：

Settings.Builder settingsBuilder = mock(Settings.Builder.class);
when(settingsBuilder.put(new String("test"), new String("test"))).thenReturn(settings.settingsBuilder());
when(settingsBuilder.build()).thenReturn(settings);

TransportClient.Builder clientBuilder = mock(TransportClient.Builder.class);
when(clientBuilder.settings(settings)).thenReturn(clientBuilder);

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);

问题：

Settings.Builder settingsBuilder = mock(Settings.Builder.class);
when(settingsBuilder.put(new String("test"), new String("test"))).thenReturn(settings.settingsBuilder());
when(settingsBuilder.build()).thenReturn(settings);

TransportClient.Builder clientBuilder = mock(TransportClient.Builder.class);
when(clientBuilder.settings(settings)).thenReturn(clientBuilder);

现在，我明白了，这可能会被抛出，因为我没有正确地模仿某些东西，但我无法找出我这次模仿的错误。如何正确模拟客户机，以便模拟所有依赖类并返回新的模拟客户机

谢谢。

我想根据你们的类名在这里猜一下

Client client = TransportClient.builder().settings(settings).build().addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("localhost"), 9300));

假设TransportClient.builder（）返回TransportClient.builder，则需要：

when(clientBuilder.settings(anyOf(Settings.class)).thenReturn(clientBuilder);
when(clientBuilder.build()).thenReturn(a transport client mock);

我假设TransportClient.addTransportAddress不需要模拟——它只需要验证。

Hi@Jerry Andrews感谢您的建议。它解决了问题，但现在我得到以下错误：需要但未调用：transportClient.addTransportAddress（localhost/127.0.0.1:9300）；我已经验证了addTransportAddress，请参见下面的验证（mockedTransportClient）.addTransportAddress（新的InetSocketTransportAddress（InetAddress.getByName（“localhost”），9300））；你知道是什么导致了这个问题吗？谢谢我建议你在addTransportAddress中添加一个captor，而不是精确地验证入站地址，然后看看它是如何被调用的（如果它被调用的话）。嗨@Jerry Andrews谢谢你的建议。它解决了问题，但现在我得到以下错误：需要但未调用：transportClient.addTransportAddress（localhost/127.0.0.1:9300）；我已经验证了addTransportAddress，请参见下面的验证（mockedTransportClient）.addTransportAddress（新的InetSocketTransportAddress（InetAddress.getByName（“localhost”），9300））；你知道是什么导致了这个问题吗？谢谢，我建议您在addTransportAddress中添加一个captor，而不是精确地验证入站地址，并查看它实际上是如何被调用的（如果它被调用的话）。
