如何为Gradle Kotlin DSL添加集成测试？遇任务未找到问题

你的问题核心是任务创建方式错误：你用tasks.named<Test>("integrationTest")尝试查找一个不存在的任务，但创建integrationTest sourceSet后，Gradle不会自动生成对应的Test任务，需要手动注册。

修正步骤 #

1. 替换任务查找为任务注册 #

把原来的named改为register，用来创建新的Test任务：

tasks {
    register<Test>("integrationTest") {
        description = "Runs Integration Tests"
        testClassesDirs = sourceSets["integrationTest"].output.classesDirs
        classpath = sourceSets["integrationTest"].runtimeClasspath
        // 可选：指定测试框架，比如JUnit Jupiter
        useJUnitPlatform()
    }
}

2. 给integrationTest sourceSet配置依赖 #

集成测试通常需要依赖主代码和测试库，给integrationTest sourceSet关联必要的依赖：

sourceSets {
    create("integrationTest") {
        java.srcDir("src/integration-test/kotlin")
        resources.srcDir("src/integration-test/resources")
        // 继承main代码的编译/运行时输出
        compileClasspath += sourceSets["main"].output
        runtimeClasspath += sourceSets["main"].output
        // 可选：继承test sourceSet的依赖（比如JUnit等）
        compileClasspath += sourceSets["test"].compileClasspath
        runtimeClasspath += sourceSets["test"].runtimeClasspath
    }
}

// 单独配置集成测试的依赖
dependencies {
    // ... 原有依赖 ...
    integrationTestImplementation(project(":common"))
    integrationTestImplementation(rootProject.libs.awssdk.lambda)
    integrationTestImplementation(libs.junit.pioneer)
}

3. 让check任务自动触发集成测试（可选） #

如果希望执行./gradlew check时自动运行集成测试，添加依赖关联：

tasks.named("check") {
    dependsOn(tasks.named("integrationTest"))
}

完整修正后的Gradle代码 #

dependencies {
    implementation(project(":common"))
    implementation(rootProject.libs.awssdk.lambda)
    implementation(rootProject.libs.awssdk.kinesis)
    implementation(rootProject.libs.awssdk.dynamodb)
    implementation(rootProject.libs.lambda.events)
    implementation(libs.awssdk.client)
    testImplementation(libs.junit.pioneer)

    // 集成测试专属依赖
    integrationTestImplementation(project(":common"))
    integrationTestImplementation(rootProject.libs.awssdk.lambda)
    integrationTestImplementation(rootProject.libs.awssdk.kinesis)
    integrationTestImplementation(rootProject.libs.awssdk.dynamodb)
    integrationTestImplementation(rootProject.libs.lambda.events)
    integrationTestImplementation(libs.awssdk.client)
    integrationTestImplementation(libs.junit.pioneer)
}

sourceSets {
    create("integrationTest") {
        java.srcDir("src/integration-test/kotlin")
        resources.srcDir("src/integration-test/resources")
        // 关联主代码和测试代码的依赖链
        compileClasspath += sourceSets["main"].output + sourceSets["test"].compileClasspath
        runtimeClasspath += sourceSets["main"].output + sourceSets["test"].runtimeClasspath
    }
}

tasks {
    register<Test>("integrationTest") {
        description = "Runs Integration Tests"
        testClassesDirs = sourceSets["integrationTest"].output.classesDirs
        classpath = sourceSets["integrationTest"].runtimeClasspath
        useJUnitPlatform()
    }

    // 让check任务包含集成测试环节
    named("check") {
        dependsOn(integrationTest)
    }
}

tasks.withType<Jar>() {
    duplicatesStrategy = DuplicatesStrategy.INCLUDE
    configurations["compileClasspath"].forEach { file: File ->
        from(zipTree(file.absoluteFile))
    }
}

现在执行./gradlew integrationTest就能正常运行集成测试了。
