Question

我的问题是如何在流量测试中上传附件以使此测试成功。

这是我在trader-demo flowtest中做的测试

private fun issue_commercial_paper( amount: Amount<Currency>,
                            issueRef: OpaqueBytes,
                            recipient: Party,
                            notary: Party,
                            progressTracker: ProgressTracker): SignedTransaction {
    val p = CommercialPaperIssueFlow(amount,issueRef,recipient,notary,progressTracker)
    val future = BankCorpNode.services.startFlow(p)
    mockNet.runNetwork()
    return future.resultFuture.getOrThrow()
}

     @Test
    fun `trade issuance`(){
        issue_commercial_paper(1000.DOLLARS,OpaqueBytes.of(42.toByte()),ACorp,notary,CommercialPaperIssueFlow.tracker())
        val pass = SellerFlow(BCorp ,500.DOLLARS, SellerFlow.tracker() )
        val future = ACorpNode.services.startFlow(pass)
        mockNet.runNetwork()
        val results = future.resultFuture.getOrThrow()
        assertNotNull(results)
    }

这是错误

你可以参考这个样本，看看你是否可以提前帮助我们 https://github.com/corda/corda/tree/c4ceca378762fe1959f075a1c8b1c301e411b6b8/samples/trader-demo

假设您的附件位于main/resources/my-attachment.jar下。在Java流测试中，您将此附件上载到节点，如下所示：

nodeA.transaction(() -> {
    InputStream attachmentStream = getClass().getClassLoader().getResourceAsStream("my-attachment.jar");
    try {
        nodeA.getServices().getAttachments().importAttachment(attachmentStream, "joel", "myAttachment");
    } catch (IOException e) {
        e.printStackTrace();
    }

    // The attachment is now uploaded to the node.
    // TODO: Remainder of the test.

    return null;
});

或者在Kotlin：

nodeA.transaction {
    val attachmentStream = javaClass.classLoader.getResourceAsStream("my-attachment.jar")
    nodeA.services.attachments.importAttachment(attachmentStream, "joel", "myAttachment")

    // The attachment is now uploaded to the node.
    // TODO: Remainder of the test.
}
