android - Jacoco 报告不排除指定文件

Question

我正在使用 Jacoco 0.8.5 和 Gradle 6.4，我有一个 Android project我正在尝试设置我的代码覆盖率。这是我的 jacoco.gradle 文件的方式:

apply plugin: 'jacoco'

def flavor = "debug"
def unitTestTask = "testDebugUnitTest"

jacoco {
    toolVersion = "0.8.5"
}

tasks.withType(Test) {
    jacoco.includeNoLocationClasses = true
}

final androidExcludes =
        ["**/R.class",
         "**/R\$*.class",
         "**/BuildConfig.*",
         "**/Manifest*.*",
         "**/*Test*.*",
         "android/**/*.*",
         "**/*_MembersInjector.class",
         "**/Dagger*Component.class",
         "**/Dagger*Component\$Builder.class",
         "**/*Module_*Factory.class",
         "**/*_Provide*Factory*.*",
         "**/*_Factory*.*",
         "**/*Activity*.*",
         "**/*Fragment*.*",
         "**/*ViewHolder*.*",
         "**/*Adapter*.*"]


task jacocoReport(type: JacocoReport, dependsOn: "${unitTestTask}") {
    reports {
        xml.enabled = true
        html.enabled = true
    }

    afterEvaluate {

        def debugTree = fileTree(dir: "$project.buildDir/intermediates/javac/${flavor}/classes",
                excludes: androidExcludes)
        def kotlinDebugTree = fileTree(dir: "$project.buildDir/tmp/kotlin-classes/${flavor}/",
                excludes: androidExcludes)
        def mainSrc = "$project.projectDir/src/main/java"

        sourceDirectories.setFrom(files([mainSrc]))
        classDirectories.setFrom(files([debugTree], [kotlinDebugTree]))
        executionData.setFrom(fileTree(dir: project.buildDir, includes: ["jacoco/${unitTestTask}.exec"]))
    }
}

我想从覆盖范围中删除一些在 androidExcludes 中设置的文件，例如 Activity 或适配器。但是目前该报告没有考虑到我的排除项，正如您在 CodeCov 的以下报告中看到的那样，我仍然有排除文件(ViewHolder 或适配器)

JaCoCo 可能不会生成覆盖率报告，而 app/src/test 中没有测试(或 app/src/androidTest 用于集成测试)。对于 JUnit 5，它还需要以下依赖项:

dependencies {

    // (Required) Writing and executing Unit Tests on the JUnit Platform
    testImplementation ("org.junit.jupiter:junit-jupiter-api:5.6.2")
    testRuntimeOnly ("org.junit.jupiter:junit-jupiter-engine:5.6.2")

    // (Optional) If you need "Parameterized Tests"
    testImplementation ("org.junit.jupiter:junit-jupiter-params:5.6.2")

    // (Optional) If you also have JUnit 4-based tests
    testImplementation ("junit:junit:4.13")
    testRuntimeOnly("org.junit.vintage:junit-vintage-engine:5.6.2")

    androidTestImplementation ("org.junit.jupiter:junit-jupiter-api:5.6.2")

    // The instrumentation test companion libraries
    androidTestImplementation ("de.mannodermaus.junit5:android-test-core:1.2.0")
    androidTestRuntimeOnly ("de.mannodermaus.junit5:android-test-runner:1.2.0")

    // testImplementation ("androidx.test:core:1.2.0")
    // androidTestImplementation("androidx.test:runner:1.2.0")
    androidTestImplementation("androidx.test:rules:1.2.0")
}

PR #23修复测试。 :jacocoTestReportDebug 的输出看起来像这样:



注意 Created with JaCoCo 0.8.5.201910111838在底部。

对于 CodeCov，您需要添加 codecov.yml ;见 ignoring paths (CodeCov 配置不关心 JaCoCo 配置)。
