JMock期望调用void方法

Question

我使用JMock在ProcessingTest类中测试以下方法：

public void handle(Process process) {
    processor.handleProcess(process);
}

我已经模拟出了processor和process类。对于我对这种特定方法的测试，我对JMock的期望如下：

checking( new Expectations() {
         {
            oneOf( ProcessingTest.this.processor ).handleProcess(
                  ProcessingTest.this.process );
         }
      } );

这导致以下错误：

unexpected invocation ...
no expectations specified
....

我认为预期中有一些不正确的地方，应该是什么？我曾试图期望中的方法调用atLeast一次，但这似乎是void方法的一个问题。

我不知道你的问题到底在哪里，因为你没有提供足够的代码。以下是使用JMock:的方法

import org.jmock.Expectations;
import org.jmock.integration.junit4.JUnitRuleMockery;
import org.jmock.lib.legacy.ClassImposteriser;
import org.junit.Rule;
import org.junit.Test;
public class ProcessingTest {
    @Rule
    public final JUnitRuleMockery mockery = new JUnitRuleMockery() {{
        setImposteriser(ClassImposteriser.INSTANCE);
    }};
    // just some dummy object, we will be comparing reference only
    private final Process process = mockery.mock(Process.class);
    private final Processor processor = mockery.mock(Processor.class);
    private final Processing processing = new Processing(processor);
    @Test
    public void test() {
        mockery.checking(new Expectations() {{
            oneOf(ProcessingTest.this.processor).handleProcess(ProcessingTest.this.process);
        }});
        processing.handle(process);
    }
}
public class Processing {
    private final Processor processor;
    public Processing(Processor processor) {
        this.processor = processor;
    }
    public void handle(Process process) {
        processor.handleProcess(process);
    }
}
public interface Processor {
    void handleProcess(Process process);
}
