与Gradle Kotlin DSL的集成测试

标签： gradle kotlin integration-testing gradle-kotlin-dsl

我正在使用this blog post为Spring Boot项目配置集成测试，但是我非常想声明源集。我还找到了this post on StackOverflow，但我想我已经走得更远了。

我的项目结构是

project
|_ src
  |_ main
  | |_ kotlin
  | |_ resources
  |_ testIntegration
  | |_ kotlin
  | |_ resources
  |_ test
  | |_ kotlin
  | |_ resources
  |_ build.gradle.kts
  |_ ... other files

和 build.gradle.kts 

import org.jetbrains.kotlin.gradle.tasks.KotlinCompile

plugins {
    idea
    kotlin("jvm")
    id("org.springframework.boot") version "2.0.5.RELEASE"
    id("org.jetbrains.kotlin.plugin.spring") version "1.2.71"
}

fun DependencyHandlerScope.springBoot(module: String) = this.compile("org.springframework.boot:spring-boot-$module:2.0.5.RELEASE")
fun DependencyHandlerScope.springBootStarter(module: String) = this.springBoot("starter-$module")

dependencies {
    springBoot("devtools")

    springBootStarter("batch")
    springBootStarter("... spring boot dependencies")


    compile("... more dependencies")

    testCompile("... more test dependencies")
}

val test by tasks.getting(Test::class) {
    useJUnitPlatform { }
}

kotlin {
    sourceSets {
        val integrationTest by creating {
            kotlin.srcDir("src/testIntegration/kotlin")
            resources.srcDir("src/testIntegration/resources")
        }
    }
}

val integrationTestCompile by configurations.creating {
    extendsFrom(configurations["testCompile"])
}
val integrationTestRuntime by configurations.creating {
    extendsFrom(configurations["testRuntime"])
}

val testIntegration by tasks.creating(Test::class) {
    group = "verification"
    testClassesDirs = kotlin.sourceSets["integrationTest"].kotlin
}

idea {
    module {
        testSourceDirs.addAll(kotlin.sourceSets["integrationTest"].kotlin.srcDirs)
        testSourceDirs.addAll(kotlin.sourceSets["integrationTest"].resources.srcDirs)
    }
}

我认为我的方向很正确。至少它不再抛出异常了：）

运行 testIntegration 任务时，得到以下输出：

Testing started at 12:08 ...
12:08:49: Executing task 'testIntegration'...

> Task :project:compileKotlin UP-TO-DATE
> Task :project:compileJava NO-SOURCE
> Task :project:processResources UP-TO-DATE
> Task :project:classes UP-TO-DATE
> Task :project:compileTestKotlin UP-TO-DATE
> Task :project:compileTestJava NO-SOURCE

> Task :project:testIntegration
BUILD SUCCESSFUL in 2s
5 actionable tasks: 1 executed, 4 up-to-date
12:08:51: Task execution finished 'testIntegration'.

此外，IntelliJ不会将testIntegration目录识别为Kotlin软件包。

答案 0 :(得分：7)

由于Kotlin Slack频道的一些帮助，我终于能够弄清楚。首先，我必须升级到Gradle版本4.10.2。

有关更多信息，请查看Gradle的这两页：

然后我只需要为IntegrationTests创建sourceSets 

sourceSets {
    create("integrationTest") {
            kotlin.srcDir("src/integrationTest/kotlin")
            resources.srcDir("src/integrationTest/resources")
            compileClasspath += sourceSets["main"].output + configurations["testRuntimeClasspath"]
            runtimeClasspath += output + compileClasspath + sourceSets["test"].runtimeClasspath
    }
}

这对于Java来说很好用，但是由于我使用的是Kotlin，因此必须添加一个额外的withConvention包装器

sourceSets {
    create("integrationTest") {
        withConvention(KotlinSourceSet::class) {
            kotlin.srcDir("src/integrationTest/kotlin")
            resources.srcDir("src/integrationTest/resources")
            compileClasspath += sourceSets["main"].output + configurations["testRuntimeClasspath"]
            runtimeClasspath += output + compileClasspath + sourceSets["test"].runtimeClasspath
        }
    }
}

在文档中，他们只放置了runtimeClasspath += output + compileClasspath，但是我添加了sourceSets["test"].runtimeClasspath，因此我可以直接使用测试依赖项，而不必为integrationTest任务声明新的依赖项。

创建sourceSet后，只需声明一个新任务即可

task<Test>("integrationTest") {
    description = "Runs the integration tests"
    group = "verification"
    testClassesDirs = sourceSets["integrationTest"].output.classesDirs
    classpath = sourceSets["integrationTest"].runtimeClasspath
    mustRunAfter(tasks["test"])
}

此后，测试仍然没有运行，但这是因为我正在使用JUnit4。所以我只需要添加useJUnitPlatform()即可使之成为最终代码

task<Test>("integrationTest") {
    description = "Runs the integration tests"
    group = "verification"
    testClassesDirs = sourceSets["integrationTest"].output.classesDirs
    classpath = sourceSets["integrationTest"].runtimeClasspath
    mustRunAfter(tasks["test"])
    useJUnitPlatform()
}

从Gradle 5.2.1开始，请参见https://docs.gradle.org/current/userguide/java_testing.html#sec:configuring_java_integration_tests 

sourceSets {
    create("intTest") {
        compileClasspath += sourceSets.main.get().output
        runtimeClasspath += sourceSets.main.get().output
    }
}

val intTestImplementation by configurations.getting {
    extendsFrom(configurations.testImplementation.get())
}

configurations["intTestRuntimeOnly"].extendsFrom(configurations.runtimeOnly.get())

dependencies {
    intTestImplementation("junit:junit:4.12")
}

val integrationTest = task<Test>("integrationTest") {
    description = "Runs integration tests."
    group = "verification"

    testClassesDirs = sourceSets["intTest"].output.classesDirs
    classpath = sourceSets["intTest"].runtimeClasspath
    shouldRunAfter("test")
}

tasks.check { dependsOn(integrationTest) }

答案 2 :(得分：0)

我不喜欢withwithConvention的使用以及kotlin src目录的设置方式。因此，在检查了gradle文档here和here之后，我想到了：

sourceSets {
    create("integrationTest") {
        kotlin {
            compileClasspath += main.get().output + configurations.testRuntimeClasspath
            runtimeClasspath += output + compileClasspath
        }
    }
}

val integrationTest = task<Test>("integrationTest") {
    description = "Runs the integration tests"
    group = "verification"
    testClassesDirs = sourceSets["integrationTest"].output.classesDirs
    classpath = sourceSets["integrationTest"].runtimeClasspath
    mustRunAfter(tasks["test"])
}

tasks.check {
    dependsOn(integrationTest)
}

在使用kotlin {并将新的IntegrationTestTask的变量使用时，我更喜欢不太冗长的样式。
