Question

我正在尝试在单元测试中模拟响应器流，我的响应器流做了几个处理配置和关闭分类帐服务的验证。我想模拟值以始终返回true，以便单元测试与网络中的其他组件没有任何依赖关系。

目的仅限于单元测试，有没有什么方法可以使用API模拟响应，因为我知道我们必须在模拟网络设置期间注册响应者类？

只需定义一个虚拟响应者流，并在设置模拟网络时注册而不是真正的响应者流：

public class FlowTests {
    private MockNetwork network;
    private StartedMockNode a;
    private StartedMockNode b;

    @InitiatedBy(ExampleFlow.Initiator.class)
    public static class DummyResponder extends FlowLogic<Void> {

        private final FlowSession otherPartySession;

        public DummyResponder(FlowSession otherPartySession) {
            this.otherPartySession = otherPartySession;
        }

        @Suspendable
        @Override
        public Void call() throws FlowException {
            otherPartySession.send(true);
            return null;
        }
    }

    @Before
    public void setup() {
        network = new MockNetwork(ImmutableList.of("com.example.contract"));
        a = network.createPartyNode(null);
        b = network.createPartyNode(null);
        // For real nodes this happens automatically, but we have to manually register the flow for tests.
        for (StartedMockNode node : ImmutableList.of(a, b)) {
            node.registerInitiatedFlow(DummyResponder.class);
        }
        network.runNetwork();
    }

    @After
    public void tearDown() {
        network.stopNodes();
    }

    @Rule
    public final ExpectedException exception = ExpectedException.none();

    @Test
    public void flowUsesDummyResponder() throws ExecutionException, InterruptedException {
        ExampleFlow.Initiator flow = new ExampleFlow.Initiator(-1, b.getInfo().getLegalIdentities().get(0));
        CordaFuture<Boolean> future = a.startFlow(flow);
        network.runNetwork();
        Boolean bool = future.get();
        assertEquals(true, bool);
    }
}
