JaCoCo不适用于Robolectric测试

Question

我想在我的android项目中生成我的JUnit测试的代码覆盖率报告，所以我添加了JaCoCo gradle插件。这是我的项目级build.gradle文件：

apply plugin: 'jacoco'

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.0.0-beta6'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots" }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

subprojects { prj ->
    apply plugin: 'jacoco'

    jacoco {
        toolVersion '0.7.6.201602180812'
    }

    task jacocoReport(type: JacocoReport, dependsOn: 'testDebugUnitTest') {
        group = 'Reporting'
        description = 'Generate Jacoco coverage reports after running tests.'

        reports {
            xml {
                enabled = true
                destination "${prj.buildDir}/reports/jacoco/jacoco.xml"
            }
            html {
                enabled = true
                destination "${prj.buildDir}/reports/jacoco"
            }
        }

        classDirectories = fileTree(
                dir: 'build/intermediates/classes/debug',
                excludes: [
                        '**/R*.class',
                        '**/BuildConfig*',
                        '**/*$$*'
                ]
        )

        sourceDirectories = files('src/main/java')
        executionData = files('build/jacoco/testDebugUnitTest.exec')

        doFirst {
            files('build/intermediates/classes/debug').getFiles().each { file ->
                if (file.name.contains('$$')) {
                    file.renameTo(file.path.replace('$$', '$'))
                }
            }
        }
    }
}

jacoco {
    toolVersion '0.7.6.201602180812'
}

task jacocoFullReport(type: JacocoReport, group: 'Coverage reports') {
    group = 'Reporting'
    description = 'Generates an aggregate report from all subprojects'

    //noinspection GrUnresolvedAccess
    dependsOn(subprojects.jacocoReport)

    additionalSourceDirs = project.files(subprojects.jacocoReport.sourceDirectories)
    sourceDirectories = project.files(subprojects.jacocoReport.sourceDirectories)
    classDirectories = project.files(subprojects.jacocoReport.classDirectories)
    executionData = project.files(subprojects.jacocoReport.executionData)

    reports {
        xml {
            enabled = true
            destination "${buildDir}/reports/jacoco/full/jacoco.xml"
        }
        html {
            enabled = true
            destination "${buildDir}/reports/jacoco/full"
        }
    }

    doFirst {
        //noinspection GroovyAssignabilityCheck
        executionData = files(executionData.findAll { it.exists() })
    }
}

它运行./gradlew jacocoFullReport很好。但遗憾的是，没有报告使用RobolectricTestRunner进行的测试的覆盖范围（测试中明显调用的指令未报告为涵盖范围）。测试没有@RunWith注释或运行MockitoJUnitTestRunner报告覆盖率很好。

任何帮助将不胜感激，以解决这个问题。

更新1：我注意到我应该使用RobolectricGradleTestRunner。但它没有帮助。

已知问题可能的解决方法 - https://github.com/jacoco/jacoco/pull/288

或者将jacoco版本降级为0.7.1.201405082137

UPDATE

不再需要解决方法。你必须使用gradle版本2.13和jacoco版本0.7.6.201602180812。

更新root build.gradle：

buildscript {
    dependencies {
        classpath 'org.jacoco:org.jacoco.core:0.7.6.201602180812'
    }
}

task wrapper( type: Wrapper ) {
  gradleVersion = '2.13'
}

运行./gradlew wrapper

更新项目build.gradle：

apply plugin: 'jacoco'

android {
  testOptions {
    unitTests.all {
      jacoco {
        includeNoLocationClasses = true
      }
    }
  }
}

Answer 3

我遇到过同样的问题。我更改了jacoco插件版本并添加了includenolocationclasses属性。这是工作的jacoco.gradle文件（我使用的是gradle wrapper 2.14.1）：

apply plugin: 'jacoco'

jacoco {
    toolVersion = "0.7.6.201602180812"
}

android {
    testOptions {
        unitTests.all {
            jacoco {
                includeNoLocationClasses = true
            }
        }
    }
}

project.afterEvaluate {
    // Grab all build types and product flavors
    def buildTypes = android.buildTypes.collect { type -> type.name }
    def productFlavors = android.productFlavors.collect { flavor -> flavor.name }
    println(buildTypes)
    println(productFlavors)
    // When no product flavors defined, use empty
    if (!productFlavors) productFlavors.add('')

    productFlavors.each { productFlavorName ->
        buildTypes.each { buildTypeName ->
            def sourceName, sourcePath
            if (!productFlavorName) {
                sourceName = sourcePath = "${buildTypeName}"
            } else {
                sourceName = "${productFlavorName}${buildTypeName.capitalize()}"
                sourcePath = "${productFlavorName}/${buildTypeName}"
            }
            def testTaskName = "test${sourceName.capitalize()}UnitTest"
            println("SourceName:${sourceName}")
            println("SourcePath:${sourcePath}")
            println("testTaskName:${testTaskName}")
            // Create coverage task of form 'testFlavorTypeCoverage' depending on 'testFlavorTypeUnitTest'
            task "${testTaskName}Coverage" (type:JacocoReport, dependsOn: "$testTaskName") {
                group = "Reporting"
                description = "Generate Jacoco coverage reports on the ${sourceName.capitalize()} build."

                classDirectories = fileTree(
                        dir: "${project.buildDir}/intermediates/classes/${sourcePath}",
                        excludes: ['**/R.class',
                                   '**/R$*.class',
                                   '**/*$ViewInjector*.*',
                                   '**/*$ViewBinder*.*',
                                   '**/BuildConfig.*',
                                   '**/Manifest*.*']
                )

                def coverageSourceDirs = [
                        "src/main/java",
                        "src/$productFlavorName/java",
                        "src/$buildTypeName/java"
                ]
                additionalSourceDirs = files(coverageSourceDirs)
                sourceDirectories = files(coverageSourceDirs)
                executionData = files("${project.buildDir}/jacoco/${testTaskName}.exec")
                println("${project.buildDir}/jacoco/${testTaskName}.exec")
                reports {
                    xml.enabled = true
                    html.enabled = true
                }
            }
        }
    }
}

Answer 4

接受的答案有点过时了。这是我们刚刚实施的类似修复程序。在模块（即app）build.gradle中添加：

apply plugin: 'jacoco'

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

这确实需要JaCoCo 7.6+，但您可能已经使用它了。

Studio的注释：

1. 这只能修复CLI。如果您使用JaCoCo从Studio运行覆盖，则仍未报告Robolectric覆盖。默认的IntelliJ Coverage Runner似乎运行正常。
2. 测试在Studio中间歇性地崩溃，除非我将-noverify添加到Android JUnit - > VM Options

Answer 5

在android studio中将覆盖运行器更改为jacoco 1-选择应用程序（项目的根目录）2单击菜单（运行 - >编辑配置 - >代码覆盖 - >选择JaCoCo）。
