unit-testing - Kotest 打破 gradle 的 :test task with java. lang.IllegalArgumentException: Received a failure event for test with unknown id

转载作者：行者123 更新时间：2023-12-03 05:18:48

我开始使用 Kotest 在 Kotlin 中进行单元测试.我使用以下与 Kotest 以某种方式集成的技术:

Kotest 本身

Kotlin/JVM

Gradle

倾城

皮特

IntelliJ IDEA 插件“Kotest”

在 gradle 中，我包含了以下依赖项:

io.kotest:kotest-runner-junit5:$kotest_version : Kotest 框架

io.kotest:kotest-assertions-core:$kotest_version : Kotest 核心 JVM 断言

io.kotest:kotest-property:$kotest_version : Kotest 属性测试

io.kotest:kotest-extensions-allure:$kotest_version : Allure

的数据收集

io.kotest:kotest-plugins-pitest:$kotest_version : Pitest 插件

问题是现在，当我通过 gradle :test 运行我的测试时任务，我得到以下异常:

java.lang.IllegalArgumentException: Received a failure event for test with unknown id '2.27'. Registered test ids: '[2.1, :test, 2.25]'

每次测试运行的未知 id/注册 id 都不同。实际上出现了很多错误，但那个是最后一个出现的错误。下面是完整的 gradle 输出(缩短的内部调用):

可能相关的内容:
1. 我在我的 build.gradle.kts 中使用自定义任务配置
我的 build.gradle.kts的以下部分文件涵盖了所有与测试相关的内容，包括设置测试环境的任务和事后清理的第二个任务:

tasks.withType<Test> {
    useJUnitPlatform()
}

allure {
    autoconfigure = false
    version = "2.13.6"
}

configure<PitestPluginExtension> {
    testPlugin.set("Kotest")
    targetClasses.set(listOf("com.example.*"))
}

val testDir1Path = "/src/test/resources/DirectoryTest"
val testDir2Path = "/src/test/resources/Create"
tasks.register("preTest") {
    doLast {
        mkdir(testDir1Path)
        file("$testDir1Path/json00.json").apply { createNewFile() }.writeText("{ \"s\": \"s\", \"i\": 0, \"b\": true}")
        file("$testDir1Path/json01.json").apply { createNewFile() }.writeText("{}")
        file("$testDir1Path/json02.json").apply { createNewFile() }.writeText("{}")
        file("$testDir1Path/json03.json").apply { createNewFile() }.writeText("{}")
        file("$testDir1Path/json04.json").apply { createNewFile() }.writeText("{}")
        file("$testDir1Path/json05.json").apply { createNewFile() }.writeText("{}")
        file("$testDir1Path/json06.json").apply { createNewFile() }.writeText("{}")
    }
}

tasks.register<Delete>("postTest") {
    for (task in tasks.withType<Test>()) {
        mustRunAfter(task)
    }
    delete(testDir1Path)
    delete(testDir2Path)
    delete("/src/test/resources/NonExistent") // might be created by :pitest
}

tasks.withType<Test>().configureEach {
    dependsOn("preTest")
}

2.首先导致错误的测试套件
该错误发生在我在以下 Kotest 测试类中工作时，更准确地说，它发生在我尝试实现测试工厂并包含它之后:

class JSONFileTests : FunSpec({
    test("Loading a file into the model JSONModel01 should work") {
        shouldNotThrowAny {
            JSONFile("$exists/json00.json", JSONModel01.serializer())
        }.get() shouldBe JSONModel01("s", 0, true)
    }

    include("JSONModel01: ", echoTests(m1))
    include("JSONModel02: ", echoTests(m2))
    include("JSONModel03: ", echoTests(m3))
    include("JSONModel04: ", echoTests(m4))
    include("JSONModel05: ", echoTests(m5))
    include("JSONModel06: ", echoTests(m6))
}) {
    companion object {
        private val m1 = JSONFile("$exists/json01.json", JSONModel01.serializer()) to JSONModel01()
        private val m2 = JSONFile("$exists/json02.json", JSONModel02.serializer()) to JSONModel02()
        private val m3 = JSONFile("$exists/json03.json", JSONModel03.serializer()) to JSONModel03()
        private val m4 = JSONFile("$exists/json04.json", JSONModel04.serializer()) to JSONModel04()
        private val m5 = JSONFile("$exists/json05.json", JSONModel05.serializer()) to JSONModel05()
        private val m6 = JSONFile("$exists/json06.json", JSONModel06.serializer()) to JSONModel06()

        private fun cleanupAll() {
            m1.first.reload()
            m2.first.reload()
            m3.first.reload()
            m4.first.reload()
            m5.first.reload()
            m6.first.reload()
        }

        private fun <T : JSONModelMarker> echoTests(model: Pair<JSONFile<T>, T>) = funSpec {
            test("Writing to and reading from file should result in the original value") {
                model.first.apply { setAndCommit(model.second) }.get() shouldBe model.second
                model.first.reload()
            }
        }
    }
}

所有 JSONModelXX类是仅用于测试的模型数据类。 JSONModelMarker是所有 JSONModelXX 实现的标记接口(interface)类。 JSONFile<T>是我要测试的类(class)。
3. IntelliJ 通知
我总是从 IntelliJ 收到“所有测试成功”的通知，但是当我查看测试工具窗口时，测试被标记为“失败”，因为 gradle 任务 :test失败的。我不知道这对这个问题有何影响。
4. 我有时也会收到不同的异常
如果我只通过 IntelliJ gutter 图标运行测试套件中的第一个测试，我会得到一个不同的异常: java.lang.ExceptionInInitializerError .我做了一些挖掘，发现 Scanner用于读取 JSONFile<T> 中 JSON 文件的内容类抛出 NoSuchElementException因为(出于某种原因)文件是空仅在执行此测试期间。这很奇怪，因为自定义 :preTest我的 build.gradle.kts 中的任务实际上在每个文件中写入了一些内容，当我查看 :preTest 之后的文件时，这些内容实际上就在那里或 :test跑了。这是完整的控制台输出:

现在我不知道这是问题的一部分还是单独的问题，但只是为了确定我想将它包括在这里。当我在 File->Settings->Build, Execution, Deployment->Build Tools->Gradle 中将测试运行器切换到 IntelliJ IDEA 时，也会出现同样的问题
就是这样!现在我的问题是:是什么导致了这个错误，我该如何解决？
与运行

Kotlin /JVM 1.4.10

kotest-runner-junit5 4.3.1

kotest 断言核心 4.3.1

kotest 属性 4.3.1

kotest-extensions-allure 4.3.1

kotest-plugins-pitest 4.3.1

毕业 6.7

魅力 2.13.6

allure gradle 插件 2.8.1

Pitest gradle 插件 1.5.1

Intellij IDEA Ultimate 2020.2

kotest IntelliJ 插件 1.1.20-IC-2020.2

openJDK 11.0.2

最佳答案

好像我找到了解决方案。
问题似乎是 Kotest(以及后来的 JUnit)想要唯一的测试，这意味着唯一的测试名称。通常，这些问题会被 Kotest IntelliJ 插件标记出来。但是如果你使用一个测试工厂，事情就有点不透明了。我假设 include(prefix, testFactory)添加 prefix到测试名称，但事实并非如此。这意味着工厂方法

private fun <T : JSONModelMarker> echoTests(model: Pair<JSONFile<T>, T>) = funSpec {
    test("Writing to and reading from file should result in the original value") {
        model.first.apply { setAndCommit(model.second) }.get() shouldBe model.second
        model.first.reload()
    }
}

实际上每次调用时都会创建一个具有固定标识符的测试。现在，当我通过 include() 多次包含这个测试工厂时，我实际上创建了重复的测试，然后使测试任务崩溃。为了解决这个问题，我刚刚实现了一个替换测试名称的功能，如下所示:

private fun <T : JSONModelMarker> echoTests(name: String, model: Pair<JSONFile<T>, T>) = funSpec {
    test("$name: Writing to and reading from file should result in the original value") {
        model.first.apply { setAndCommit(model.second) }.get() shouldBe model.second
        model.first.reload()
    }
}

现在，当我调用 include()方法，我省略了前缀(因为它无关紧要)，并在工厂方法调用中添加了一个唯一的名称(以前是前缀):

include(echoTests("JSONModel01", m1))

在我这样做之后，错误不再发生。
