JMock 期望调用 void 方法

Question

我正在使用JMock 在 ProcessingTest 类中测试以下方法：

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

我已经模拟了 processor 和 process 类。对于我对这个特定方法的测试，我对JMock 的期望如下：

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

这会导致以下错误：

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

我认为期望中有一些不正确的地方，它们应该是什么？ 我曾试图期望该方法在调用atLeast 一次，但这似乎是void 方法的问题。

我不知道您的问题出在哪里，因为您没有提供足够的代码。这是使用 JMock 执行此操作的方法：

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);

}
