为什么我的流测试未能检查某些节点中的事务，即使它们存在于存储中？

Posted 2021-04-28

错误：java.lang.AssertionError：expected：net.corda.core.transactions.SignedTransaction但是：net.corda.core.transactions.SignedTransaction预期：net.corda.core.transactions.SignedTransaction实际：net.corda.core。 transactions.SignedTransaction

据我所知，预期和实际交易都是相同的，但它仍然抛出错误。它正在通过其他测试但突然失败，没有任何令人满意的调试信息。下面是我测试的代码：

@Test
    public void flowRecordsATransactionInBothPartiesTransactionStorages() throws Exception {
        SignedTransaction signedTx = createPlacementCompleteTxn();

        // We check the recorded transaction in both vaults.
        for (StartedMockNode node : ImmutableList.of(participantsNodes.get(0), participantsNodes.get(1), participantsNodes.get(3))) {
            assertEquals(signedTx, node.getServices().getValidatedTransactions().getTransaction(signedTx.getId()));
        }

答案

这对我在Corda 4上工作正常。例如，以下测试通过：

@Test
public void recordedTransactionIsCorrect() throws Exception {
    ExampleFlow.Initiator flow = new ExampleFlow.Initiator(1, b.getInfo().getLegalIdentities().get(0));
    CordaFuture<SignedTransaction> future = a.startFlow(flow);
    network.runNetwork();
    SignedTransaction signedTx = future.get();

    // We check the recorded transaction in both vaults.
    for (StartedMockNode node : ImmutableList.of(a, b)) {
        SignedTransaction recordedTx = node.getServices().getValidatedTransactions().getTransaction(signedTx.getId());
        assertEquals(recordedTx, signedTx);
    }
}
