corda-集成测试期间无法解析匿名参与方

(corda - Failed to resolve anonymous Party during integration test)

发布于 2021-01-02 18:52:46

我开发了一个简单的状态“物品”，代表卖家将出售给一群匿名买家的物品。我写了流程测试，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。由于卖方节点启动无法通过其公钥解析买方，因此我的流程失败。我能够在没有任何自己的代码的情况下重现代码。我觉得我错过了注册步骤或其他什么，但卖家节点可以使用 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析买方节点时遇到问题。

要复制，克隆cordapps-kotlin-template 并用以下代码替换DriverBasedTest.kt 的内容，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
}

测试结果如下：

请注意，TestIdentity即使你提供相同的名称，Corda也会以这种方式产生误导，因为它们是新的且语义上独立的身份。

很高兴听到你们都准备好了穆斯塔法。祝你好运

是的，模板代码非常具有误导性，因为辅助函数startnodes将TestIdentity用作输入并让我认为输入覆盖了节点标识。我不得不花几个小时才明白事实并非如此。
