Corda 在集成测试期间解析匿名参与方失败

我开发了一个简单的状态“item”，表示卖家将向一群匿名买家出售的物品。我写了流量测试，一切似乎都很顺利。我还想实施集成测试，以确认我的逻辑工作正常。我的流程失败，因为启动的卖方节点无法从其公钥解析买方。我能够在没有自己代码的情况下复制代码。我觉得我错过了注册步骤或其他什么，但是卖家节点可以使用X500名称解析买家节点。我有点困惑，为什么我在通过其公钥解决买方节点时遇到问题

要复制、克隆cordapps kotlin模板并用以下代码替换DriverBasedTest.kt的内容，请运行

gradlew integrationTest

import net.corda.core.identity.AbstractParty
import net.corda.core.identity.CordaX500Name
import net.corda.core.utilities.getOrThrow
import net.corda.testing.core.TestIdentity
import net.corda.testing.driver.DriverDSL
import net.corda.testing.driver.DriverParameters
import net.corda.testing.driver.NodeHandle
import net.corda.testing.driver.driver
import net.corda.testing.node.User
import org.junit.Test
import kotlin.test.assertEquals

class AnonymousTest {
    private val seller = TestIdentity(CordaX500Name("Seller", "", "GB"))
    private val buyer = TestIdentity(CordaX500Name("Buyer", "", "US"))

    @Test
    fun `anonymous resolution test`() = withDriver {
        val sellerUser = User("sellerUser", "testPassword1", permissions = setOf("ALL"))
        val buyerUser = User("buyerUser", "testPassword1", permissions = setOf("ALL"))

        val sellerHandle = startNode(providedName = seller.name, rpcUsers = listOf(sellerUser)).getOrThrow()
        startNode(providedName = buyer.name, rpcUsers = listOf(buyerUser)).getOrThrow()
        val resolvedNameBuyerA = sellerHandle.resolveName(buyer.name)
        assertEquals(buyer.name, resolvedNameBuyerA)
        val resolveFromAnonymous = sellerHandle.resolveFromAnonymous(buyer.party.anonymise())
        assertEquals(buyer.name, resolveFromAnonymous)
    }

    // Runs a test inside the Driver DSL, which provides useful functions for starting nodes, etc.
    private fun withDriver(test: DriverDSL.() -> Unit) = driver(
            DriverParameters(isDebug = true, startNodesInProcess = true)
    ) { test() }

    // Makes an RPC call to retrieve another node's name from the network map.
    private fun NodeHandle.resolveName(name: CordaX500Name) = rpc.wellKnownPartyFromX500Name(name)!!.name

    private fun NodeHandle.resolveFromAnonymous(name: AbstractParty) = rpc.wellKnownPartyFromAnonymous(name)!!.name
}

试验结果如下：

请注意，Corda

TestIdentity

可能会产生误导，因为它们是新的、语义上独立的身份，即使您提供相同的名称

很高兴听到你们都准备好了，穆斯塔法。好运

TestIdentity

使用与节点中同名公钥不匹配的公钥创建标识。这个故事的寓意是TestIdentity不应该用于集成测试。是的，模板代码具有极大的误导性，因为helper函数

startnodes

将

TestIdentity

作为输入，让我认为输入超过了节点标识。我花了几个小时才明白事实并非如此。
