如何使用 Junit5 和 Jacoco 配置 build.gradle 以進行測試覆蓋

[英]How to configure build.gradle using Junit5 and Jacoco for test coverage

問題描述

我正在嘗試配置 build.gradle 文件，以便它同時支持 Junit 5 和 Jacoco。 我之前使用過 useJunitPlatform，但它會產生另一個錯誤。 我也嘗試了其他一些方法，但都無法成功生成 Jacoco 報告。 然而，這個配置成功地為我生成了 Jacoco 報告，但它也給了我一個例外。 下面是我的 build.gradle 文件。

plugins {
    // Build "fat" jars for deployment
    id 'com.github.johnrengelman.shadow' version '5.2.0'

    // Apply the java plugin to add support for Java
    id 'java'

    // Apply the application plugin to add support for building a CLI application.
    id 'application'

    // Deploy directly to heroku without using Git
    id "com.heroku.sdk.heroku-gradle" version "1.0.4"

    // Lombok provides shorthand for repetitive Java tasks
    id "io.freefair.lombok" version "4.1.6"

    // Spotless to format code easily
    id "com.diffplug.gradle.spotless" version "3.27.1"

    // Jacoco test coverage
    id 'jacoco'
}

repositories {
    // Use jcenter for resolving dependencies.
    // You can declare any Maven/Ivy/file repository here.
    jcenter()
}

dependencies {
    // Simple HTTP framework - http://sparkjava.com/
    implementation 'com.sparkjava:spark-core:2.9.1'

    // Basic logging support; used by Spark
    implementation "org.slf4j:slf4j-simple:1.7.25"

    // Jackson to serialize/deserialize JSON
    implementation 'com.fasterxml.jackson.core:jackson-databind:2.10.2'

    // Use JUnit Jupiter API for testing.
    testImplementation 'org.junit.jupiter:junit-jupiter-api:5.6.0'

    testImplementation 'org.junit.platform:junit-platform-launcher:1.5.2'

    // Use JUnit Jupiter Engine for testing.
    testRuntimeOnly 'org.junit.jupiter:junit-jupiter-engine:5.5.2'

    // Use dagger for dependency injection
    implementation 'com.google.dagger:dagger:2.26'
    annotationProcessor 'com.google.dagger:dagger-compiler:2.26'

    // Annotations such as Nullable
    implementation 'com.google.code.findbugs:annotations:3.0.1'

    // Force JRE Guava to work around issues with Truth
    testImplementation "com.google.guava:guava:28.2-jre"

    // Fluent assertions for testing
    testImplementation 'com.google.truth:truth:1.0.1'

    // MongoDB client
    implementation 'org.mongodb:mongodb-driver:3.12.1'
}

application {
    // Define the main class for the application.
    mainClassName = 'edu.northeastern.cs5500.delivery.App'
}

jacoco {
    toolVersion = "0.8.5"
    reportsDir = file("$buildDir/customJacocoReportDir")
}

jacocoTestReport {
    reports {
        xml.enabled false
        csv.enabled false
        html.destination file("${buildDir}/jacocoHtml")
    }
    afterEvaluate {
        classDirectories.from = files(classDirectories.files.collect {
            fileTree(dir: it, exclude: [
                    '**/model/**',
                    '**/view/**',
                    '**/utils/**',
                    '**/service/**'
            ])
        })
    }
    doLast {
        println "file://$buildDir/jacocoHtml/index.html"
    }
}

test {
    // Use junit platform for unit tests
    useJUnit()
    finalizedBy jacocoTestReport
}

// Heroku will run the 'stage' task on deployment via git
task stage(dependsOn: ['clean', 'shadowJar'])
shadowJar.mustRunAfter clean

// Force all builds to be clean builds due to Dagger problems
build.mustRunAfter clean
build.dependsOn += 'clean'

run.mustRunAfter clean
run.dependsOn += 'clean'

// Target Java 1.11 - make sure system.properties matches this as well
sourceCompatibility = 1.11
targetCompatibility = 1.11

sourceSets {
    main {
        java {
            srcDirs 'src/main/java'
            srcDirs 'build/generated/sources/annotationProcessor/java/main'
        }
    }
    test {
        java {
            srcDirs 'src/test/java'
            srcDirs 'build/generated/sources/annotationProcessor/java/test'
        }
    }
}

spotless {
    format 'misc', {
        target '**/*.gradle', '**/*.md', '**/.gitignore'
        targetExclude 'build/**'

        trimTrailingWhitespace()
        indentWithSpaces()
        endWithNewline()
        paddedCell()
    }
    java {
        targetExclude 'build/**'
        googleJavaFormat().aosp()
    }
}

謝謝你的幫助！

2 個解決方案

解決方案1
 4 已采納  2020-11-13 08:48:06

根據您的錯誤信息

Caused by: java.lang.IllegalArgumentException: Unsupported class 文件主要版本 59

根據https://en.wikipedia.org/wiki/Java_class_file你正在使用 Java 15。

根據https://www.jacoco.org/jacoco/trunk/doc/changes.html支持 Java 15 在 JaCoCo 版本 0.8.6 中添加

因此，要么您不需要 Java 15 並且可以使用早期版本，例如 11 (LTS)，要么您需要更改

jacoco {
    toolVersion = "0.8.5"

在

jacoco {
    toolVersion = "0.8.6"

對我來說，問題出在 com.github.johnrengelman.shadow 版本上，升級到 6.1.0 版本后解決了
