KotlinJS 测试不包括公共类

Question

我有一个编译为 JS 和 JVM 的多平台 kotlin 项目，具有以下构建配置：

常见 - build.gradle

plugins {
    id 'kotlin-platform-common' version '1.3.10'
}

repositories {
    mavenCentral()
    jcenter()
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib-common:1.3.10"
    compile 'org.jetbrains.kotlinx:kotlinx-coroutines-core-common:1.0.1'

    testCompile "org.jetbrains.kotlin:kotlin-test-annotations-common"
    testCompile "org.jetbrains.kotlin:kotlin-test-common"
}

js - build.gradle

plugins {
    id 'kotlin-platform-js' version '1.3.10'
}

repositories {
    mavenCentral()
    jcenter()
}

dependencies {
    expectedBy project(":Lib-common")

    compile "org.jetbrains.kotlin:kotlin-stdlib-js:1.3.10"
    compile 'org.jetbrains.kotlinx:kotlinx-coroutines-core-js:1.0.1'

    testCompile "org.jetbrains.kotlin:kotlin-test"
    testCompile "org.jetbrains.kotlin:kotlin-test-js"
}

compileKotlin2Js {
    kotlinOptions.outputFile = "${projectDir}/output/lib."
    kotlinOptions.moduleKind = "commonjs"
    kotlinOptions.metaInfo = false
}

compileTestKotlin2Js {
    kotlinOptions.outputFile = "${projectDir}/output/lib_test.js"
    kotlinOptions.moduleKind = "commonjs"
    kotlinOptions.metaInfo = false
}

jvm - build.gradle

plugins {
    id 'kotlin-platform-jvm' version '1.3.10'
}

repositories {
    mavenCentral()
    jcenter()
}

dependencies {
    expectedBy project(":Lib-common")

    compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.3.10"
    compile 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.0.1'

    compile 'org.apache.httpcomponents:httpcore:4.4.11'
    compile 'org.apache.httpcomponents:httpclient:4.5.7'
    compile 'org.apache.httpcomponents:httpmime:4.5.7'

    testCompile "junit:junit:4.12"
    testCompile "org.jetbrains.kotlin:kotlin-test"
    testCompile "org.jetbrains.kotlin:kotlin-test-junit"
}

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

sourceCompatibility = "1.8"

我在 JVM 上按预期运行的公共模块中有一个测试。 JS模块通过compileKotlin2Js任务成功编译生成js文件，但是当我运行compileTestKotlin2Js时，公共模块中的测试类找不到它正在测试的类。这是我尝试运行compileTestKotlin2Js时的失败：

> Task :Lib-js:classes
e: <location>\Lib\Lib-common\src\test\kotlin\mypackage\ClientTest.kt: (3, 45): Unresolved reference: Client


FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':Lib-js:compileTestKotlin2Js'.
> Compilation error. See log for more details

kotlin-platform-js gradle 插件不创建任务来运行测试，它只编译 main 和 test 源集中的 Kotlin 代码，所以你需要自己设置所有的 JS 测试基础设施。

当所有代码都驻留在应用了kotlin-mutliplatform 插件的单个模块中时，我建议切换到新的多平台项目创作方法。该插件可以开箱即用地配置 JS 测试任务。

此类项目的 build.gradle 文件如下所示：

plugins {
    id 'org.jetbrains.kotlin.multiplatform' version '1.3.50'
}
repositories {
    mavenCentral()
}
group 'com.example'
version '0.0.1'

kotlin {
    jvm()
    js {
        nodejs { // target and run tests on node.js
        }
    }

    sourceSets {
        commonMain {
            dependencies {
                implementation kotlin('stdlib-common')
            }
        }
        commonTest {
            dependencies {
                implementation kotlin('test-common')
                implementation kotlin('test-annotations-common')
            }
        }
        jvmMain {
            dependencies {
                implementation kotlin('stdlib-jdk8')
            }
        }
        jvmTest {
            dependencies {
                implementation kotlin('test')
                implementation kotlin('test-junit')
            }
        }
        jsMain {
            dependencies {
                implementation kotlin('stdlib-js')
            }
        }
        jsTest {
            dependencies {
                implementation kotlin('test-js')
            }
        }
    }
}
